TECHNICAL FIELD
[0003] The present invention relates to targeted genome editing in
eukaryotic cells or organisms. More particularly, the present
invention relates to a composition for cleaving a target DNA in
eukaryotic cells or organisms comprising a guide RNA specific for
the target DNA and Cas protein-encoding nucleic acid or Cas
protein, and use thereof.
BACKGROUND ART
[0004] CRISPRs (Clustered Regularly Interspaced Short Palindromic
Repeats) are loci containing multiple short direct repeats that are
found in the genomes of approximately 40% of sequenced bacteria and
90% of sequenced archaea. CRISPR functions as a prokaryotic immune
system, in that it confers resistance to exogenous genetic elements
such as plasmids and phages. The CRISPR system provides a form of
acquired immunity. Short segments of foreign DNA, called spacers,
are incorporated into the genome between CRISPR repeats, and serve
as a memory of past exposures. CRISPR spacers are then used to
recognize and silence exogenous genetic elements in a manner
analogous to RNAi in eukaryotic organisms.
[0005] Cas9, an essential protein component in the Type II
CRISPR/Cas system, forms an active endonuclease when complexed with
two RNAs termed CRISPR RNA (crRNA) and trans-activating crRNA
(tracrRNA), thereby slicing foreign genetic elements in invading
phages or plasmids to protect the host cells. crRNA is transcribed
from the CRISPR element in the host genome, which was previously
captured from such foreign invaders. Recently, Jinek et al. (1)
demonstrated that a single-chain chimeric RNA produced by fusing an
essential portion of crRNA and tracrRNA could replace the two RNAs
in the Cas9/RNA complex to form a functional endonuclease.
[0006] CRISPR/Cas systems offer an advantage to zinc finger and
transcription activator-like effector DNA-binding proteins, as the
site specificity in nucleotide binding CRISPR-Cas proteins is
governed by a RNA molecule instead of the DNA-binding protein,
which can be more challenging to design and synthesize.
[0007] However, until now, a genome editing method using the
RNA-guided endonuclease (RGEN) based on CRISPR/Cas system has not
been developed.
[0008] Meanwhile, Restriction fragment length polymorphism (RFLP)
is one of the oldest, most convenient, and least expensive methods
of genotyping that is still used widely in molecular biology and
genetics but is often limited by the lack of appropriate sites
recognized by restriction endonucleases.
[0009] Engineered nuclease-induced mutations are detected by
various methods, which include mismatch-sensitive T7 endonuclease I
(T7E1) or Surveyor nuclease assays, RFLP, capillary electrophoresis
of fluorescent PCR products, Dideoxy sequencing, and deep
sequencing. The T7E1 and Surveyor assays are widely used but are
cumbersome. Furthermore, theses enzymes tend to underestimate
mutation frequencies because mutant sequences can form homoduplexes
with each other and cannot distinguish homozygous bi-allelic mutant
clones from wildtype cells. RFLP is free of these limitations and
therefore is a method of choice. Indeed, RFLP was one of the first
methods to detect engineered nuclease-mediated mutations in cells
and animals. Unfortunately, however, RFLP is limited by the
availability of appropriate restriction sites. It is possible that
no restriction sites are available at the target site of
interest.
DISCLOSURE OF INVENTION
Technical Problem
[0010] Until now, a genome editing and genotyping method using the
RNA-guided endonuclease (RGEN) based on CRISPR/Cas system has not
been developed.
[0011] Under these circumstances, the present inventors have made
many efforts to develop a genome editing method based on CRISPR/Cas
system and finally established a programmable RNA-guided
endonuclease that cleave DNA in a targeted manner in eukaryotic
cells and organisms.
[0012] In addition, the present inventors have made many efforts to
develop a novel method of using RNA-guided endonucleases (RGENs) in
RFLP analysis. They have used RGENs to genotype recurrent mutations
found in cancer and those induced in cells and organisms by
engineered nucleases including RGENs themselves, thereby completing
the present invention.

Chr. 5 N/A (SEQ ID NO: 131), each of which carries 3-base
mismatches with the CCR5 on-target (SEQ ID NO: 127). Mismatched
bases are underlined. FIG. 4B: The T7E1 assay was used to
investigate whether these sites were mutated in cells transfected
with the Cas9/RNA complex. No mutations were detected at these
sites. N/A (not applicable), an intergenic site. FIG. 4C: Cas9 did

BEST MODE FOR CARRYING OUT THE INVENTION
[0075] In accordance with one aspect of the invention, the present
invention provides a composition for cleaving target DNA in
eukaryotic cells or organisms comprising a guide RNA specific for
target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein. In addition, the
present invention provides a use of the composition for cleaving
target DNA in eukaryotic cells or organisms comprising a guide RNA
specific for target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein.
[0076] In the present invention, the composition is also referred
to as a RNA-guided endonuclease (RGEN) composition.
[0077] ZFNs and TALENs enable targeted mutagenesis in mammalian
cells, model organisms, plants, and livestock, but the mutation
frequencies obtained with individual nucleases are widely different
from each other. Furthermore, some ZFNs and TALENs fail to show any
genome editing activities. DNA methylation may limit the binding of
these engineered nucleases to target sites. In addition, it is
technically challenging and time-consuming to make customized
nucleases.
[0078] The present inventors have developed a new RNA-guided
endonuclease composition based on Cas protein to overcome the
disadvantages of ZFNs and TALENs.
[0079] Prior to the present invention, an endonuclease activity of
Cas proteins has been known. However, it has not been known whether
the endonuclease activity of Cas protein would function in an
eukaryotic cell because of the complexity of the eukaryotic genome.
Further, until now, a composition comprising Cas protein or Cas
protein-encoding nucleic acid and a guide RNA specific for the
target DNA to cleave a target DNA in eukaryotic cells or organisms
has not been developed.
[0080] Compared to ZFNs and TALENs, the present RGEN composition
based on Cas protein can be more readily customized because only
the synthetic guide RNA component is replaced to make a new
genome-editing nuclease. No sub-cloning steps are involved to make
customized RNA guided endonucleases. Furthermore, the relatively
small size of the Cas gene (for example, 4.2 kbp for Cas9) as
compared to a pair of TALEN genes (.about.6 kbp) provides an
advantage for this RNA-guided endonuclease composition in some
applications such as virus-mediated gene delivery. Further, this
RNA-guided endonuclease does not have off-target effects and thus
does not induce unwanted mutations, deletion, inversions, and
duplications. These features make the present RNA-guided
endonuclease composition a scalable, versatile, and convenient
tools for genome engineering in eukaryotic cells and organisms. In
addition, RGEN can be designed to target any DNA sequence, almost
any single nucleotide polymorphism or small insertion/deletion
(indel) can be analyzed via RGEN-mediated RFLP. The specificity of
RGENs is determined by the RNA component that hybridizes with a
target DNA sequence of up to 20 base pairs (bp) in length and by
the Cas9 protein that recognize the protospacer-adjacent motif
(PAM). RGENs are readily reprogrammed by replacing the RNA
component. Therefore, RGENs provide a platform to use simple and
robust RFLP analysis for various sequence variations.
[0081] The target DNA may be an endogenous DNA, or artificial DNA,
preferably, endogenous DNA.
[0082] As used herein, the term "Cas protein" refers to an
essential protein component in the CRISPR/Cas system, forms an
active endonuclease or nickase when complexed with two RNAs termed
CRISPR RNA (crRNA) and trans-activating crRNA (tracrRNA).
[0083] The information on the gene and protein of Cas are available
from GenBank of National Center for Biotechnology Information
(NCBI), without limitation.
[0084] The CRISPR-associated (cas) genes encoding Cas proteins are
often associated with CRISPR repeat-spacer arrays. More than forty
different Cas protein families have been described. Of these
protein families, Cas1 appears to be ubiquitous among different
CRISPR/Cas systems. There are three types of CRISPR-Cas system.
Among them, Type II CRISPR/Cas system involving Cas9 protein and
crRNA and tracrRNA is representative and is well known. Particular
combinations of cas genes and repeat structures have been used to
define 8 CRISPR subtypes (Ecoli, Ypest, Nmeni, Dvulg, Tneap, Hmari,
Apern, and Mtube).
[0085] The Cas protein may be linked to a protein transduction
domain. The protein transduction domain may be poly-arginine or a
TAT protein derived from HIV, but it is not limited thereto.
[0086] The present composition may comprise Cas component in the
form of a protein or in the form of a nucleic acid encoding Cas
protein.
[0087] In the present invention, Cas protein may be any Cas protein
provided that it has an endonuclease or nickase activity when
complexed with a guide RNA.
[0088] Preferably, Cas protein is Cas9 protein or variants
thereof.
[0089] The variant of the Cas9 protein may be a mutant form of Cas9
in which the cataytic asapartate residue is changed to any other
amino acid. Preferably, the other amino acid may be an alanine, but
it is not limited thereto.
[0090] Further, Cas protein may be the one isolated from an
organism such as Streptococcus sp., preferably Streptococcus
pyogens or a recombinant protein, but it is not limited
thereto.
[0091] The Cas protein derived from Streptococcus pyogens may
recognizes NGG trinucleotide. The Cas protein may comprise an amino
acid sequence of SEQ ID NO: 109, but it is not limited thereto.
[0092] The term "recombinant" when used with reference, e.g., to a
cell, nucleic acid, protein, or vector, indicates that the cell,
nucleic acid, protein or vector, has been modified by the
introduction of a heterologous nucleic acid or protein or the
alteration of a native nucleic acid or protein, or that the cell is
derived from a cell so modified. Thus, for example, a recombinant
Cas protein may be generated by reconstituting Cas protein-encoding
sequence using the human codon table.
[0093] As for the present invention, Cas protein-encoding nucleic
acid may be a form of vector, such as plasmid comprising
Cas-encoding sequence under a promoter such as CMV or CAG. When Cas
protein is Cas9, Cas9 encoding sequence may be derived from
Streptococcus sp., and preferably derived from Streptococcus
pyogenes. For example, Cas9 encoding nucleic acid may comprise the
nucleotide sequence of SEQ ID. NO: 1. Moreover, Cas9 encoding
nucleic acid may comprise the nucleotide sequence having homology
of at least 50% to the sequence of SEQ ID NO: 1, preferably at
least 60, 70, 80, 90, 95, 97, 98, or 99% to the SEQ ID NO:1, but it
is not limited thereto. Cas9 encoding nucleic acid may comprise the
nucleotide sequence of SEQ ID NOs. 108, 110, 106, or 107.
[0094] As used herein, the term "guide RNA" refers to a RNA which
is specific for the target DNA and can form a complex with Cas
protein and bring Cas protein to the target DNA.
[0095] In the present invention, the guide RNA may consist of two
RNA, i.e., CRISPR RNA(crRNA) and transactivating crRNA(tracrRNA) or
be a single-chain RNA (sgRNA) produced by fusion of an essential
portion of crRNA and tracrRNA.
[0096] The guide RNA may be a dualRNA comprising a crRNA and a
tracrRNA.
[0097] If the guide RNA comprises the essential portion of crRNA
and tracrRNA and a portion complementary to a target, any guide RNA
may be used in the present invention.
[0098] The crRNA may hybridize with a target DNA.
[0099] The RGEN may consist of Cas protein, and dualRNA (invariable
tracrRNA and target-specific crRNA), or Cas protein and sgRNA
(fusion of an essential portion of invariable tracrRNA and
target-specific crRNA), and may be readily reprogrammed by
replacing crRNA.
[0100] The guide RNA further comprises one or more additional
nucleotides at the 5' end of the single-chain guide RNA or the
crRNA of the dualRNA.
[0101] Preferably, the guide RNA further comprises 2-additional
guanine nucleotides at the 5' end of the single-chain guide RNA or
the crRNA of the dualRNA.
[0102] The guide RNA may be transferred into a cell or an organism
in the form of RNA or DNA that encodes the guide RNA. The guide RNA
may be in the form of an isolated RNA, RNA incorporated into a
viral vector, or is encoded in a vector. Preferably, the vector may
be a viral vector, plasmid vector, or agrobacterium vector, but it
is not limited thereto.
[0103] A DNA that encodes the guide RNA may be a vector comprising
a sequence coding for the guide RNA. For example, the guide RNA may
be transferred into a cell or organism by transfecting the cell or
organism with the isolated guide RNA or plasmid DNA comprising a
sequence coding for the guide RNA and a promoter.
[0104] Alternatively, the guide RNA may be transferred into a cell
or organism using virus-mediated gene delivery.
[0105] When the guide RNA is transfected in the form of an isolated
RNA into a cell or organism, the guide RNA may be prepared by in
vitro transcription using any in vitro transcription system known
in the art. The guide RNA is preferably transferred to a cell in
the form of isolated RNA rather than in the form of plasmid
comprising encoding sequence for a guide RNA. As used herein, the
term "isolated RNA" may be interchangeable to "naked RNA". This is
cost- and time-saving because it does not require a step of
cloning. However, the use of plasmid DNA or virus-mediated gene
delivery for transfection of the guide RNA is not excluded.
[0106] The present RGEN composition comprising Cas protein or Cas
protein-encoding nucleic acid and a guide RNA can specifically
cleave a target DNA due to a specificity of the guide RNA for a
target and an endonuclease or nickase activity of Cas protein.
[0107] As used herein, the term "cleavage" refers to the breakage
of the covalent backbone of a nucleotide molecule.
[0108] In the present invention, a guide RNA may be prepared to be
specific for any target which is to be cleaved. Therefore, the
present RGEN composition can cleave any target DNA by manipulating
or genotyping the target-specific portion of the guide RNA.
[0109] The guide RNA and the Cas protein may function as a pair. As
used herein, the term "paired Cas nickase" may refer to the guide
RNA and the Cas protein functioning as a pair. The pair comprises
two guide RNAs. The guide RNA and Cas protein may function as a
pair, and induce two nicks on different DNA strand. The two nicks
may be separated by at least 100 bps, but are not limited
thereto.
[0110] In the Example, the present inventors confirmed that paired
Cas nickase allow targeted mutagenesis and large deletions of up to
1-kbp chromosomal segments in human cells. Importantly, paired
nickases did not induce indels at off-target sites at which their
corresponding nucleases induce mutations. Furthermore, unlike
nucleases, paired nickases did not promote unwanted translocations
associated with off-target DNA cleavages. In principle, paired
nickases double the specificity of Cas9-mediated mutagenesis and
will broaden the utility of RNA-guided enzymes in applications that
require precise genome editing such as gene and cell therapy.
[0111] In the present invention, the composition may be used in the
genotyping of a genome in the eukaryotic cells or organisms in
vitro.
[0112] In one specific embodiment, the guide RNA may comprise the
nucleotide sequence of Seq ID. No. 1, wherein the portion of
nucleotide position 3.about.22 is a target-specific portion and
thus, the sequence of this portion may be changed depending on a
target.
[0113] As used herein, a eukaryotic cell or organism may be yeast,
fungus, protozoa, plant, higher plant, and insect, or amphibian
cells, or mammalian cells such as CHO, HeLa, HEK293, and COS-1, for
example, cultured cells (in vitro), graft cells and primary cell
culture (in vitro and ex vivo), and in vivo cells, and also
mammalian cells including human, which are commonly used in the
art, without limitation.
[0114] In one specific embodiment, it was found that Cas9
protein/single-chain guide RNA could generate site-specific DNA
double-strand breaks in vitro and in mammalian cells, whose
spontaneous repair induced targeted genome mutations at high
frequencies.
[0115] Moreover, it was found that gene-knockout mice could be
induced by the injection of Cas9 protein/guide RNA complexes or
Cas9 mRNA/guide RNA into one-cell stage embryo and germ-line
transmittable mutations could be generated by Cas9/guide RNA
system.
[0116] Using Cas protein rather than a nucleic acid encoding Cas
protein to induce a targeted mutagenesis is advantageous because
exogeneous DNA is not introduced into an organism. Thus, the
composition comprising Cas protein and a guide RNA may be used to
develop therapeutics or value-added crops, livestock, poultry,
fish, pets, etc.
[0117] In accordance with another aspect of the invention, the
present invention provides a composition for inducing targeted
mutagenesis in eukaryotic cells or organisms, comprising a guide
RNA specific for target DNA or DNA that encodes the guide RNA, and
Cas protein-encoding nucleic acid or Cas protein. In addition, the
present invention provides a use of the composition for inducing
targeted mutagenesis in eukaryotic cells or organisms, comprising a
guide RNA specific for target DNA or DNA that encodes the guide
RNA, and Cas protein-encoding nucleic acid or Cas protein.
[0118] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
[0119] In accordance with another aspect of the invention, the
present invention provides a kit for cleaving a target DNA or
inducing targeted mutagenesis in eukaryotic cells or organisms
comprising a guide RNA specific for target DNA or DNA that encodes
the guide RNA, and Cas protein-encoding nucleic acid or Cas
protein.
[0120] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
[0121] The kit may comprise a guide RNA and Cas protein-encoding
nucleic acid or Cas protein as separate components or as one
composition.
[0122] The present kit may comprise some additional components
necessary for transferring the guide RNA and Cas component to a
cell or an organism. For example, the kit may comprise an injection
buffer such as DEPC-treated injection buffer, and materials
necessary for analysis of mutation of a target DNA, but are not
limited thereto.
[0123] In accordance with another aspect, the present invention
provides a method for preparing a eukaryotic cell or organism
comprising Cas protein and a guide RNA comprising a step of
co-transfecting or serial-transfecting the eukaryotic cell or
organism with a Cas protein-encoding nucleic acid or Cas protein,
and a guide RNA or DNA that encodes the guide RNA.
[0124] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
[0125] In the present invention, a Cas protein-encoding nucleic
acid or Cas protein and a guide RNA or DNA that encodes the guide
RNA may be transferred into a cell by various methods known in the
art, such as microinjection, electroporation, DEAE-dextran
treatment, lipofection, nanoparticle-mediated transfection, protein
transduction domain mediated transduction, virus-mediated gene
delivery, and PEG-mediated transfection in protoplast, and so on,
but are not limited thereto. Also, a Cas protein encoding nucleic
acid or Cas protein and a guide RNA may be transferred into an
organism by various method known in the art to administer a gene or
a protein such as injection. A Cas protein-encoding nucleic acid or
Cas protein may be transferred into a cell in the form of complex
with a guide RNA, or separately. Cas protein fused to a protein
transduction domain such as Tat can also be delivered efficiently
into cells.
[0126] Preferably, the eukarotic cell or organisms is
co-transfected or serial-transfected with a Cas9 protein and a
guide RNA.
[0127] The serial-transfection may be performed by transfection
with Cas protein-encoding nucleic acid first, followed by second
transfection with naked guide RNA. Preferably, the second
transfection is after 3, 6, 12, 18, 24 hours, but it is not limited
thereto.
[0128] In accordance with another aspect, the present invention
provides a eukaryotic cell or organism comprising a guide RNA
specific for target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein.
[0129] The eukaryotic cells or organisms may be prepared by
transferring the composition comprising a guide RNA specific for
target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein into the cell or
organism.
[0130] The eukaryotic cell may be yeast, fungus, protozoa, higher
plant, and insect, or amphibian cells, or mammalian cells such as
CHO, HeLa, HEK293, and COS-1, for example, cultured cells (in
vitro), graft cells and primary cell culture (in vitro and ex
vivo), and in vivo cells, and also mammalian cells including human,
which are commonly used in the art, without limitation. Further the
organism may be yeast, fungus, protozoa, plant, higher plant,
insect, amphibian, or mammal.
[0131] In accordance with another aspect of the invention, the
present invention provides a method for cleaving a target DNA or
inducing targeted mutagenesis in eukaryotic cells or organisms,
comprising a step of treating a cell or organism comprising a
target DNA with a composition comprising a guide RNA specific for
target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein.
[0132] The step of treating a cell or organism with the composition
may be performed by transferring the present composition comprising
a guide RNA specific for target DNA or DNA that encodes the guide
RNA, and Cas protein-encoding nucleic acid or Cas protein into the
cell or organism.
[0133] As described in the above, such transfer may be performed by
microinjection, transfection, electroporation, and so on.
[0134] In accordance with another aspect of the invention, the
present invention provides an embryo comprising a genome edited by
the present RGEN composition comprising a guide RNA specific for
target DNA or DNA that encodes the guide RNA, and Cas
protein-encoding nucleic acid or Cas protein.
[0135] Any embryo can be used in the present invention, and for the
present invention, the embryo may be an embryo of a mouse. The
embryo may be produced by injecting PMSG (Pregnant Mare Serum
Gonadotropin) and hCG (human Choirinic Gonadotropin) into a female
mouse of 4 to 7 weeks and the super-ovulated female mouse may be
mated to males, and the fertilized embryos may be collected from
oviduts.
[0136] The present RGEN composition introduced into an embryo can
cleave a target DNA complementary to the guide RNA by the action of
Cas protein and cause a mutation in the target DNA. Thus, the
embryo into which the present RGEN composition has been introduced
has an edited genome.
[0137] In one specific embodiment, it was found that the present
RGEN composition could cause a mutation in a mouse embryo and the
mutation could be transmitted to offsprings.
[0138] A method for introducing the RGEN composition into the
embryo may be any method known in the art, such as microinjection,
stem cell insertion, retrovirus insertion, and so on. Preferably, a
microinjection technique can be used.
[0139] In accordance with another aspect, the present invention
provides a genome-modified animal obtained by transferring the
embryo comprising a genome edited by the present RGEN composition
into the oviducts of an animal.
[0140] In the present invention, the term "genome-modified animal"
refers to an animal of which genome has been modified in the stage
of embryo by the present RGEN composition and the type of the
animal is not limited.
[0141] The genome-modified animal has mutations caused by a
targeted mutagenesis based on the present RGEN composition. The
mutations may be any one of deletion, insertion, translocation,
inversion. The site of mutation depends on the sequence of guide
RNA of the RGEN composition.
[0142] The genome-modified animal having a mutation of a gene may
be used to determine the function of the gene.
[0143] In accordance with another aspect of the invention, the
present invention provides a method of preparing a genome-modified
animal comprising a step of introducing the present RGEN
composition comprising a guide RNA specific for the target DNA or
DNA that encodes the guide RNA and Cas protein-encoding nucleic
acid or Cas protein into an embryo of an animal; and a step of
transferring the embryo into a oviduct of pseudopregnant foster
mother to produce a genome-modified animal.
[0144] The step of introducing the present RGEN composition may be
accomplished by any method known in the art such as microinjection,
stem cell insertion, retroviral insertion, and so on.
[0145] In accordance with another aspect of the invention, the
present invention provides a plant regenerated form the
genome-modified protoplasts prepared by the method for eukaryotic
cells comprising the RGEN composition.
[0146] In accordance with another aspect of the invention, the
present invention provides a composition for genotyping mutations
or variations in an isolated biological sample, comprising a guide
RNA specific for the target DNA sequence Cas protein. In addition,
the present invention provides a composition for genotyping nucleic
acid sequences in pathogenic microorganisms in an isolated
biological sample, comprising a guide RNA specific for the target
DNA sequence and Cas protein.
[0147] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
[0148] As used herein the term "genotyping" refers to the
"Restriction fragment length polymorphism (RFLP) assay".
[0149] RFLP may be used in 1) the detection of indel in cells or
organisms induced by the engineered nucleases, 2) the genotyping
naturally-occurring mutations or variations in cells or organisms,
or 3) the genotyping the DNA of infected pathogenic microorganisms
including virus or bacteria, etc.
[0150] The mutations or variation may be induced by engineered
nucleases in cells.
[0151] The engineered nuclease may be a Zinc Finger Nuclease
(ZFNs), Transcription Activator-Like Effector Nucleases (TALENs),
or RGENs, but it is not limited thereto.
[0152] As used herein the term "biological sample" includes samples
for analysis, such as tissues, cells, whole blood, semm, plasma,
saliva, sputum, cerbrospinal fluid or urine, but is not limited
thereto
[0153] The mutations or variation may be a naturally-occurring
mutations or variations.
[0154] The mutations or variations are induced by the pathogenic
microorganisms. Namely, the mutations or variation occure due to
the infection of pathogenic microorganisms, when the pathogenic
microorganisms are detected, the biological sample is identified as
infected.
[0155] The pathogenic microorganisms may be virus or bacteria, but
are not limited thereto.
[0156] Engineered nuclease-induced mutations are detected by
various methods, which include mismatch-sensitive Surveyor or T7
endonuclease I (T7E1) assays, RFLP analysis, fluorescent PCR, DNA
melting analysis, and Sanger and deep sequencing. The T7E1 and
Surveyor assays are widely used but often underestimate mutation
frequencies because the assays detect heteroduplexes (formed by the
hybridization of mutant and wild-type sequences or two different
mutant sequences); they fail to detect homoduplexes formed by the
hybridization of two identical mutant sequences. Thus, these assays
cannot distinguish homozygous bialleic mutant clones from wild-type
cells nor heterozygous biallelic mutants from heterozygous
monoalleic mutants (FIG. 22). In addition, sequence polymorphisms
near the nuclease target site can produce confounding results
because the enzymes can cleave heteroduplexes formed by
hybridization of these different wild-type alleles. RFLP analysis
is free of these limitations and therefore is a method of choice.
Indeed, RFLP analysis was one of the first methods used to detect
engineered nuclease-mediated mutations. Unfortunately, however, it
is limited by the availability of appropriate restriction
sites.
[0157] In accordance with another aspect of the invention, the
present invention provides a kit for genotyping mutations or
variations in an isolated biological sample, comprising the
composition for genotyping mutations or variations in an isolated
biological sample. In addition, the present invention provides a
kit for genotyping nucleic acid sequences in pathogenic
microorganisms in an isolated biological sample, comprising a guide
RNA specific for the target DNA sequence and Cas protein.
[0158] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
[0159] In accordance with another aspect of the invention, the
present invention provides a method of genotyping mutations or
variations in an isolated biological sample, using the composition
for genotyping mutations or variations in an isolated biological
sample. In addition, the present invention provides a method of
genotyping nucleic acid sequences in pathogenic microorganisms in
an isolated biological sample, comprising a guide RNA specific for
the target DNA sequence and Cas protein.
[0160] A guide RNA, Cas protein-encoding nucleic acid or Cas
protein are as described in the above.
MODE FOR THE INVENTION
[0161] Hereinafter, the present invention will be described in more
detail with reference to Examples. However, these Examples are for
illustrative purposes only, and the invention is not intended to be
limited by these Examples.
Example 1: Genome Editing Assay
[0162] 1-1. DNA Cleavage Activity of Cas9 Protein
[0163] Firstly, the DNA cleavage activity of Cas9 derived from
Streptococcus pyogenes in the presence or absence of a chimeric
guide RNA in vitro was tested.
[0164] To this end, recombinant Cas9 protein that was expressed in
and purified from E. coli was used to cleave a predigested or
circular plasmid DNA that contained the 23-base pair (bp) human
CCR5 target sequence. A Cas9 target sequence consists of a 20-bp
DNA sequence complementary to crRNA or a chimeric guide RNA and the
trinucleotide (5'-NGG-3') protospacer adjacent motif (PAM)
recognized by Cas9 itself (FIG. 1A).
[0165] Specifically, the Cas9-coding sequence (4,104 bp), derived
from Streptococcus pyogenes strain M1 GAS (NC 002737.1), was
reconstituted using the human codon usage table and synthesized
using oligonucleotides. First, 1-kb DNA segments were assembled
using overlapping .about.35-mer oligonucleotides and Phusion
polymerase (New England Biolabs) and cloned into T-vector
(SolGent). A full-length Cas9 sequence was assembled using four
1-kbp DNA segments by overlap PCR. The Cas9-encoding DNA segment
was subcloned into p3s, which was derived from pcDNA3.1
(Invitrogen). In this vector, a peptide tag
(NH2-GGSGPPKKKRKVYPYDVPDYA-COOH, SEQ ID NO: 2) containing the HA
epitope and a nuclear localization signal (NLS) was added to the
C-terminus of Cas9. Expression and nuclear localization of the Cas9
protein in HEK 293T cells were confirmed by western blotting using
anti-HA antibody (Santa Cruz).
[0166] Then, the Cas9 cassette was subcloned into pET28-b(+) and
transformed into BL21 (DE3). The expression of Cas9 was induced
using 0.5 mM IPTG for 4 h at 25.degree. C. The Cas9 protein
containing the His6-tag at the C terminus was purified using Ni-NTA
agarose resin (Qiagen) and dialyzed against 20 mM HEPES (pH 7.5),
150 mM KCl, 1 mM DTT, and 10% glycerol (1). Purified Cas9 (50 nM)
was incubated with super-coiled or pre-digested plasmid DNA (300
ng) and chimeric RNA (50 nM) in a reaction volume of 20 .mu.l in
NEB buffer 3 for 1 h at 37.degree. C. Digested DNA was analyzed by
electrophoresis using 0.8% agarose gels.
[0167] Cas9 cleaved the plasmid DNA efficiently at the expected
position only in the presence of the synthetic RNA and did not
cleave a control plasmid that lacked the target sequence (FIG.
1B).
[0168] 1-2. DNA Cleavage by Cas9/Guide RNA Complex in Human
Cells
[0169] A RFP-GFP reporter was used to investigate whether the
Cas9/guide RNA complex can cleave the target sequence incorporated
between the RFP and GFP sequences in mammalian cells.
[0170] In this reporter, the GFP sequence is fused to the RFP
sequence out-of-frame (2). The active GFP is expressed only when
the target sequence is cleaved by site-specific nucleases, which
causes frameshifting small insertions or deletions (indels) around
the target sequence via error-prone non-homologous end-joining
(NHEJ) repair of the double-strand break (DSB) (FIG. 2).
[0171] The RFP-GFP reporter plasmids used in this study were
constructed as described previously (2). Oligonucleotides
corresponding to target sites (Table 1) were synthesized (Macrogen)
and annealed. The annealed oligonucleotides were ligated into a
reporter vector digested with EcoRI and BamHI.
[0172] HEK 293T cells were co-transfected with Cas9-encoding
plasmid (0.8 .mu.g) and the RFP-GFP reporter plasmid (0.2 .mu.g) in
a 24-well plate using Lipofectamine 2000 (Invitrogen).
[0173] Meanwhile, the in vitro transcribed chimeric RNA had been
prepared as follows. RNA was in vitro transcribed through run-off
reactions using the MEGAshortscript T7 kit (Ambion) according to
the manufacturer's manual. Templates for RNA in vitro transcription
were generated by annealing two complementary single strand DNAs or
by PCR amplification (Table 1). Transcribed RNA was resolved on a
8% denaturing urea-PAGE gel. The gel slice containing RNA was cut
out and transferred to probe elution buffer. RNA was recovered in
nuclease-free water followed by phenol:chloroform extraction,
chloroform extraction, and ethanol precipitation. Purified RNAs
were quantified by spectrometry.
[0174] At 12 h post transfection, chimeric RNA (1 .mu.g) prepared
by in vitro transcription was transfected using Lipofectamine
2000.
[0175] At 3d post-transfection, transfected cells were subjected to
flow cytometry and cells expressing both RFP and GFP were
counted.
[0176] It was found that GFP-expressing cells were obtained only
when the cells were transfected first with the Cas9 plasmid and
then with the guide RNA 12 h later (FIG. 2), demonstrating that
RGENs could recognize and cleave the target DNA sequence in
cultured human cells. Thus GFP-experssing cells were obtained by
serial-transfection of the Cas9 plasmid and the guide RNA rather
than co-transfection.

[0177] 1-3. Targeted Disruption of Endogeneous Genes in Mammalian
Cells by RGEN
[0178] To test whether RGENs could be used for targeted disruption
of endogenous genes in mammalian cells, genomic DNA isolated from
transfected cells using T7 endonuclease I (T7E1), a
mismatch-sensitive endonuclease that specifically recognizes and
cleaves heteroduplexes formed by the hybridization of wild-type and
mutant DNA sequences was analyzed (3).
[0179] To introduce DSBs in mammalian cells using RGENs,
2.times.10.sup.6 K562 cells were transfected with 20 .mu.g of
Cas9-encoding plasmid using the 4D-Nucleofector, SF Cell Line
4D-Nucleofector X Kit, Program FF-120 (Lonza) according to the
manufacturer's protocol. For this experiment, K562 (ATCC, CCL-243)
cells were grown in RPMI-1640 with 10% FBS and the
penicillin/streptomycin mix (100 U/ml and 100 .mu.g/ml,
respectively).
[0180] After 24 h, 10-40 .mu.g of in vitro transcribed chimeric RNA
was nucleofected into 1.times.10.sup.6 K562 cells. The in vitro
transcribed chimeric RNA had been prepared as described in the
Example 1-2.
[0181] Cells were collected two days after RNA transfection and
genomic DNA was isolated. The region including the target site was
PCR-amplified using the primers described in Table 1. The amplicons
were subjected to the T7E1 assay as described previously (3). For
sequencing analysis, PCR products corresponding to genomic
modifications were purified and cloned into the T-Blunt vector
using the T-Blunt PCR Cloning Kit (SolGent). Cloned products were
sequenced using the M13 primer.
[0182] It was found that mutations were induced only when the cells
were transfected serially with Cas9-encoding plasmid and then with
guide RNA (FIG. 3). Mutation frequencies (Indels (%) in FIG. 3A)
estimated from the relative DNA band intensities were RNA-dosage
dependent, ranging from 1.3% to 5.1%. DNA sequencing analysis of
the PCR amplicons corroborated the induction of RGEN-mediated
mutations at the endogenous sites. Indels and microhomologies,
characteristic of error-prone NHEJ, were observed at the target
site. The mutation frequency measured by direct sequencing was 7.3%
(=7 mutant clones/96 clones), on par with those obtained with zinc
finger nucleases (ZFNs) or transcription-activator-like effector
nucleases (TALENs).
[0183] Serial-transfection of Cas9 plasmid and guide RNA was
required to induce mutations in cells. But when plasmids that
encode guide RNA, serial transfection was unnecessary and cells
were co-transfected with Cas9 plasmid and guide RNA-encoding
plasmid.
[0184] In the meantime, both ZFNs and TALENs have been successfully
developed to disrupt the human CCR5 gene (3-6), which encodes a
G-protein-coupled chemokine receptor, an essential co-receptor of
HIV infection. A CCR5-specific ZFN is now under clinical
investigation in the US for the treatment of AIDS (7). These ZFNs
and TALENs, however, have off-target effects, inducing both local
mutations at sites whose sequences are homologous to the on-target
sequence (6, 8-10) and genome rearrangements that arise from the
repair of two concurrent DSBs induced at on-target and off-target
sites (11-12). The most striking off-target sites associated with
these CCR5-specific engineered nucleases reside in the CCR2 locus,
a close homolog of CCR5, located 15-kbp upstream of CCR5. To avoid
off-target mutations in the CCR2 gene and unwanted deletions,
inversions, and duplications of the 15-kbp chromosomal segment
between the CCR5 on-target and CCR2 off-target sites, the present
inventors intentionally chose the target site of our CCR5-specific
RGEN to recognize a region within the CCR5 sequence that has no
apparent homology with the CCR2 sequence.
[0185] The present inventors investigated whether the CCR5-specific
RGEN had off-target effects. To this end, we searched for potential
off-target sites in the human genome by identifying sites that are
most homologous to the intended 23-bp target sequence. As expected,
no such sites were found in the CCR2 gene. Instead, four sites,
each of which carries 3-base mismatches with the on-target site,
were found (FIG. 4A). The T7E1 assays showed that mutations were
not detected at these sites (assay sensitivity, .about.0.5%),
demonstrating exquisite specificities of RGENs (FIG. 4B).
Furthermore, PCR was used to detect the induction of chromosomal
deletions in cells separately transfected with plasmids encoding
the ZFN and RGEN specific to CCR5. Whereas the ZFN induced
deletions, the RGEN did not (FIG. 4C).
[0186] Next, RGENs was reprogrammed by replacing the CCR5-specific
guide RNA with a newly-synthesized RNA designed to target the human
C4BPB gene, which encodes the beta chain of C4b-binding protein, a
transcription factor. This RGEN induced mutations at the
chromosomal target site in K562 cells at high frequencies (FIG.
3B). Mutation frequencies measured by the T7E1 assay and by direct
sequencing were 14% and 8.3% (=4 mutant clones/48 clones),
respectively. Out of four mutant sequences, two clones contained a
single-base or two-base insertion precisely at the cleavage site, a
pattern that was also observed at the CCR5 target site. These
results indicate that RGENs cleave chromosomal target DNA at
expected positions in cells.
Example 2: Proteinaceous RGEN-Mediated Genome Editing
[0187] RGENs can be delivered into cells in many different forms.
RGENs consist of Cas9 protein, crRNA, and tracrRNA. The two RNAs
can be fused to form a single-chain guide RNA (sgRNA). A plasmid
that encodes Cas9 under a promoter such as CMV or CAG can be
transfected into cells. crRNA, tracrRNA, or sgRNA can also be
expressed in cells using plasmids that encode these RNAs. Use of
plasmids, however, often results in integration of the whole or
part of the plasmids in the host genome. The bacterial sequences
incorporated in plasmid DNA can cause unwanted immune response in
vivo. Cells transfected with plasmid for cell therapy or animals
and plants derived from DNA-transfected cells must go through a
costly and lengthy regulation procedure before market approval in
most developed countries. Furthermore, plasmid DNA can persist in
cells for several days post-transfection, aggravating off-target
effects of RGENs.
[0188] Here, we used recombinant Cas9 protein complexed with in
vitro transcribed guide RNA to induce targeted disruption of
endogenous genes in human cells. Recombinant Cas9 protein fused
with the hexa-histidine tag was expressed in and purified from E.
coli using standard Ni ion affinity chromatography and gel
filtration. Purifed recombinant Cas9 protein was concentrated in
storage buffer (20 mM HEPES pH 7.5, 150 mM KCl, 1 mM DTT, and 10%
glycerol). Cas9 protein/sgRNA complex was introduced directly into
K562 cells by nucleofection: 1.times.10.sup.6 K562 cells were
transfected with 22.5-225 (1.4-14 .mu.M) of Cas9 protein mixed with
100 .mu.g (29 .mu.M) of in vitro transcribed sgRNA (or crRNA40 ug
and tracrRNA 80 ug) in 100p1 solution using the 4D-Nucleofector, SF
Cell Line 4D-Nucleofector X Kit, Program FF-120 (Lonza) according
to the manufacturer's protocol. After nucleofection, cells were
placed in growth media in 6-well plates and incubated for 48 hr.
When 2.times.10.sup.5 K562 cells were transfected with 1/5
scale-downed protocol, 4.5-45 .mu.g of Cas9 protein mixed with 6-60
ug of in vitro transcribed sgRNA (or crRNA 8 .mu.g and tracrRNA 16
.mu.g) were used and nucleofected in 20p1 solution. Nucleofected
cell were then placed in growth media in 48-well plates. After 48
hr, cells were collected and genomic DNA was isolated. The genomic
DNA region spanning the target site was PCR-amplified and subjected
to the T7E1 assay.
[0189] As shown in FIG. 10, Cas9protein/sgRNA complex induced
targeted mutation at the CCR5 locus at frequencies that ranged from
4.8 to 38% in a sgRNA or Cas9 protein dose-dependent manner, on par
with the frequency obtained with Cas9 plasmid transfection (45%).
Cas9 protein/crRNA/tracrRNA complex was able to induce mutations at
a frequency of 9.4%. Cas9 protein alone failed to induce mutations.
When 2.times.10.sup.5 cells were transfected with 1/5 scale-downed
doses of Cas9 protein and sgRNA, mutation frequencies at the CCR5
locus ranged from 2.7 to 57% in a dose-dependent manner, greater
than that obtained with co-transfection of Cas9 plasmid and sgRNA
plasmid (32%).
[0190] We also tested Cas9 protein/sgRNA complex that targets the
ABCC11 gene and found that this complex induced indels at a
frequency of 35%, demonstrating general utility of this method.

Example 3: RNA-Guided Genome Editing in Mice
[0191] To examine the gene-targeting potential of RGENs in
pronuclear (PN)-stage mouse embryos, the forkhead box N1 (Foxn1)
gene, which is important for thymus development and keratinocyte
differentiation (Nehls et al., 1996), and the protein kinase, DNA
activated, catalytic polypeptide (Prkdc) gene, which encodes an
enzyme critical for DNA DSB repair and recombination (Taccioli et
al., 1998) were used.
[0192] To evaluate the genome-editing activity of the Foxn1-RGEN,
we injected Cas9 mRNA (10-ng/.mu.l solution) with various doses of
the sgRNA (FIG. 5a) into the cytoplasm of PN-stage mouse embryos,
and conducted T7 endonuclease I (T7E1) assays (Kim et al. 2009)
using genomic DNAs obtained from in vitro cultivated embryos (FIG.
6a).
[0193] Alternatively, we directly injected the RGEN in the form of
recombinant Cas9 protein (0.3 to 30 ng/.mu.l) complexedwith the
two-fold molar excess of Foxn1-specific sgRNA (0.14 to 14 ng/.mu.l)
into the cytoplasm or pronucleus of one-cell mouse embryos, and
analyzed mutations in the Foxn1 gene using in vitro cultivated
embryos (FIG. 7).
[0194] Specifically, Cas9 mRNA and sgRNAs were synthesized in vitro
from linear DNA templates using the mMESSAGE mMACHINE T7 Ultra kit
(Ambion) and MEGAshortscript T7 kit (Ambion), respectively,
according to the manufacturers' instructions, and were diluted with
appropriate amounts of diethyl pyrocarbonate (DEPC, Sigma)-treated
injection buffer (0.25 mM EDTA, 10 mM Tris, pH 7.4). Templates for
sgRNA synthesis were generated using oligonucleotides listed in
Table 3. Recombinant Cas9 protein was obtained from ToolGen,
Inc.

[0195] All animal experiments were performed in accordance with the
Korean Food and Drug Administration (KFDA) guidelines. Protocols
were reviewed and approved by the Institutional Animal Care and Use
Committees (IACUC) of the Laboratory Animal Research Center at
Yonsei University (Permit Number: 2013-0099). All mice were
maintained in the specific pathogen-free facility of the Yonsei
Laboratory Animal Research Center. FVB/NTac (Taconic) and ICR mouse
strains were used as embryo donors and foster mothers,
respectively. Female FVB/NTac mice (7-8 weeks old) were
super-ovulated by intra-peritoneal injections of 5 IU pregnant mare
serum gonadotropin (PMSG, Sigma) and 5 IU human chorionic
gonadotropin (hCG, Sigma) at 48-hour intervals. The super-ovulated
female mice were mated to FVB/NTac stud males, and fertilized
embryos were collected from oviducts.
[0196] Cas9 mRNA and sgRNAs in M2 medium (Sigma) were injected into
the cytoplasm of fertilized eggs with well-recognized pronuclei
using a Piezo-driven micromanipulator (Prime Tech).
[0197] In the case of injection of recombinant Cas9 protein, the
recombinant Cas9 protein: Foxn1-sgRNA complex was diluted with
DEPC-treated injection buffer (0.25 mM EDTA, 10 mM Tris, pH 7.4)
and injected into male pronuclei using a TransferMan NK2
micromanipulator and a FemtoJet microinjector (Eppendorf).
[0198] The manipulated embryos were transferred into the oviducts
of pseudopregnant foster mothers to produce live animals, or were
cultivated in vitro for further analyses.
[0199] To screen F0 mice and in vitro cultivated mouse embryos with
RGEN-induced mutations, T7E1 assays were performed as previously
described using genomic DNA samples from tail biopsies and lysates
of whole embryos (Cho et al., 2013).
[0200] Briefly, the genomic region encompassing the RGEN target
site was PCR-amplified, melted, and re-annealed to form
heteroduplex DNA, which was treated with T7 endonuclease 1 (New
England Biolabs), and then analyzed by agarose gel electrophoresis.
Potential off-target sites were identified by searching with bowtie
0.12.9 and were also similarly monitored by T7E1 assays. The primer
pairs used in these assays were listed in Tables 4 and 5.

[0201] Mutant founders identified by the T7E1 assay were further
analyzed by fPCR. Appropriate regions of genomic DNA were sequenced
as described previously (Sung et al., 2013). For routine PCR
genotyping of F1 progenies, the following primer pairs were used
for both wild-type and mutant alleles: 5'-CTACTCCCTCCGCAGTCTGA-3'
(SEQ ID NO: 69) and 5'-CCAGGCCTAGGTTCCAGGTA-3' (SEQ ID NO: 70) for
the Foxn1 gene, 5'-CCCCAGCATTGCAGATTTCC-3' (SEQ ID NO: 71) and
5'-AGGGCTTCTTCTCTACAATCACG-3' (SEQ ID NO: 72) for Prkdc gene.
[0202] In the case of injection of Cas9 mRNA, mutant fractions (the
number of mutant embryos/the number of total embryos) were
dose-dependent, ranging from 33% (1 ng/.mu.l sgRNA) to 91% (100
ng/.mu.l) (FIG. 6b). Sequence analysis confirmed mutations in the
Foxn1 gene; most mutations were small deletions (FIG. 6c),
reminiscent of those induced by ZFNs and TALENs (Kim et al.,
2013).
[0203] In the case of injection of Cas9 protein, these injection
doses and methods minimally affected the survival and development
of mouse embryos in vitro: over 70% of RGEN-injected embryos
hatched out normally in both experiments. Again, mutant fractions
obtained with Cas9 protein injection were dose-dependent, and
reached up to 88% at the highest dose via pronucleus injection and
to 71% via intra-cytoplasmic injection (FIGS. 7a and 7b). Similar
to the mutation patterns induced by Cas9 mRNA plus sgRNA (FIG. 6c),
those induced by the Cas9 protein-sgRNA complex were mostly small
deletions (FIG. 7c). These results clearly demonstrate that RGENs
have high gene-targeting activity in mouse embryos.
[0204] Encouraged by the high mutant frequencies and low
cytotoxicity induced by RGENs, we produced live animals by
transferring the mouse embryos into the oviducts of pseudo-pregnant
foster mothers.
[0205] Notably, the birth rates were very high, ranging from 58% to
73%, and were not affected by the increasing doses of Foxn1-sgRNA
(Table 6).

(Tables 6 and 7, FIG. 5b).

[0207] To generate Prkdc-targeted mice, we applied a 5-fold higher
concentration of Cas9 mRNA (50 ng/.mu.l) with increasing doses of
Prkdc-sgRNA (50, 100, and 250 ng/.mu.l). Again, the birth rates
were very high, ranging from 51% to 60%, enough to produce a
sufficient number of newborns for the analysis (Table 6). The
mutant fraction was 57% (21 mutant founders among 37 newborns) at
the maximum dose of Prkdc-sgRNA. These birth rates obtained with
RGENs were approximately 2- to 10-fold higher than those with
TALENs reported in our previous study (Sung et al., 2013). These
results demonstrate that RGENs are potent gene-targeting reagents
with minimal toxicity.
[0208] To test the germ-line transmission of the mutant alleles, we
crossed the Foxn1 mutant founder #108, a mosaic with four different
alleles (FIG. 5c, and Table 8) with wild-type mice, and monitored
the genotypes of F1 offspring.

[0209] As expected, all the progenies were heterozygous mutants
possessing the wild-type allele and one of the mutant alleles (FIG.
5d). We also confirmed the germ-line transmission in independent
founder mice of Foxn1 (FIG. 8) and Prkdc (FIG. 9). To the best of
our knowledge, these results provide the first evidence that
RGEN-induced mutant alleles are stably transmitted to F1 progenies
in animals.
Example 4: RNA-Guided Genome Editing in Plants
[0210] 4-1. Production of Cas9 protein
[0211] The Cas9 coding sequence (4104 bps), derived from
Streptococcus pyogenes strain M1 GAS (NC 002737.1), was cloned to
pET28-b(+) plasmid. A nuclear targeting sequence (NLS) was included
at the protein N terminus to ensure the localization of the protein
to the nucleus. pET28-b(+) plasmid containing Cas9 ORF was
transformed into BL21(DE3). Cas9 was then induced using 0.2 mM IPTG
for 16 hrs at 18.degree. C. and purified using Ni-NTA agarose beads
(Qiagen) following the manufacturer's instructions. Purified Cas9
protein was concentrated using Ultracel-100K (Millipore).
[0212] 4-2. Production of Guide RNA
[0213] The genomic sequence of the Arabidopsis gene encoding the
BRI1 was screened for the presence of a NGG motif, the so called
protospacer adjacent motif (PAM), in an exon which is required for
Cas9 targeting To disrupt the BRI1 gene in Arabidopsis, we
identified two RGEN target sites in an exon that contain the NGG
motif. sgRNAs were produced in vitor using template DNA. Each
template DNA was generated by extension with two partially
overlapped oligonucleotides (Macrogen, Table X1) and Phusion
polymerase (Thermo Scientific) using the following

[0214] The extended DNA was purified and used as a template for the
in vitro production of the guide RNA's using the MEGAshortscript T7
kit (Life Technologies). Guide RNA were then purified by
Phenol/Chloroform extraction and ethanol precipitation. To prepare
Cas9/sgRNA complexes, 10 ul of purified Cas9 protein (12
.mu.g/.mu.l) and 4 ul each of two sgRNAs (11 .mu.g/.mu.l) were
mixed in 20 .mu.l NEB3 buffer (New England Biolabs) and incubated
for 10 min at 37.degree. C.
[0215] 4-3. Transfection of Cas9/sgRNA Complex to Protoplast
[0216] The leaves of 4-week-old Arabidopsis seedlings grown
aseptically in petri dishes were digested in enzyme solution (1%
cellulose R10, 0.5% macerozyme R10, 450 mM mannitol, 20 mM MES pH
5.7 and CPW salt) for 8-16 hrs at 25.degree. C. with 40 rpm shaking
in the dark. Enzyme/protoplast solutions were filtered and
centrifuged at 100.times.g for 3-5 min. Protoplasts were
re-suspended in CPW solution after counting cells under the
microscope (.times.100) using a hemacytometer. Finally, protoplasts
were re-suspended at 1.times.10.sup.6/ml in MMG solution (4 mM
HEPES pH 5.7, 400 mM mannitol and 15 mM MgCl2). To transfect the
protoplasts with Cas9/sgRNA complex, 200 .mu.L (200,000
protoplasts) of the protoplast suspension were gently mixed with
3.3 or 10 uL of Cas9/sgRNA complex [Cas9 protein (6 .mu.g/.mu.L)
and two sgRNAs (2.2 .mu.g/.mu.L each)] and 200 ul of 40%
polyethylene glycol transfection buffer (40% PEG4000, 200 mM
mannitol and 100 mM CaCl.sub.2)) in 2 ml tubes. After 5-20 min
incubation at room temperature, transfection was stopped by adding
wash buffer with W5 solution (2 mM MES pH 5.7, 154 mM NaCl, 125 mM
CaCl.sub.2) and 5 mM KCl). Protoplasts were then collected by
centrifugation for 5 min at 100.times.g, washed with 1 ml of W5
solution, centrifuged for another 5 min at 100.times.g. The density
of protoplasts was adjusted to 1.times.10.sup.3/ml and they were
cultured in modified KM 8p liquid medium with 400 mM glucose.
[0217] 4-4. Detection of Mutations in Arabidopsis Protoplasts and
Plants
[0218] After 24 hr or 72 hr post-transfection, protoplasts were
collected and genomic DNA was isolated. The genomic DNA region
spanning the two target sites was PCR-amplified and subjected to
the T7E1 assay. As shown in FIG. 11, indels were induced by RGENs
at high frequencies that ranged from 50% to 70%. Surprisingly,
mutations were induced at 24 hr post-transfection. Apparently, Cas9
protein functions immediately after transfection. PCR products were
purified and cloned into T-Blunt PCR Cloning Kit (Solgent).
Plasmids were purified and subjected to Sanger sequencing with M13F
primer. One mutant sequence had a 7-bp deletion at one site (FIG.
12). The other three mutant sequences had deletions of
.about.220-bp DNA segments between the two RGEN site.
Example 5: Cas9 Protein Transduction Using a Cell-Penutrating
Peptide or Protein Transduction Domain
[0219] 5-1. Construction of his-Cas9-Encoding Plasmid
[0220] Cas9 with a cysteine at the C-terminal was prepared by PCR
amplification using the previously described Cas9 plasmid {Cho,
2013 #166} as the template and cloned into pET28-(a) vector
(Novagen, Merk Millipore, Germany) containing His-tag at the
N-terminus.
[0221] 5-2. Cell Culture
[0222] 293T (Human embryonic kidney cell line), and HeLa (human
ovarian cancer cell line) were grown in DMEM (GIBCO-BRL Rockville)
supplemented with 10% FBS and 1% penicillin and streptomycin.
[0223] 5-3. Expression and Purification of Cas9 Protein
[0224] To express the Cas9 protein, E. coli BL21 cells were
transformed with the pET28-(a) vector encoding Cas9 and plated onto
Luria-Bertani (LB) agar medium containing 50 .mu.g/mL kanamycin
(Amresco, Solon, Ohio). Next day, a single colony was picked and
cultured in LB broth containing 50 .mu.g/mL kanamycin at 37.degree.
C. overnight. Following day, this starter culture at 0.1 OD600 was
inoculated into Luria broth containing 50 .mu.g/mL kanamycin and
incubated for 2 hrs at 37.degree. C. until OD600 reached to
0.6-0.8. To induce Cas9 protein expression, the cells were cultured
at 30.degree. C. overnight after addition of
isopropyl-.beta.-D-thiogalactopyranoside (IPTG) (Promega, Madison,
Wis.) to the final concentration of 0.5 mM.
[0225] The cells were collected by centrifugation at 4000 rpm for
15-20 mins, resuspended in a lysis buffer (20 mM Iris-Cl pH8.0, 300
mM NaCl, 20 mM imidazole, 1.times. protease inhibitor cocktail, 1
mg/ml lysozyme), and lysed by sonication (40% duty, 10 sec pulse,
30 sec rest, for 10 mins on ice). The soluble fraction was
separated as the supernatant after centrifugation at 15,000 rpm for
20 mins at 4.degree. C. Cas9 protein was purified at 4.degree. C.
using a column containing Ni-NTA agarose resin (QIAGEN) and AKTA
prime instrument (AKTA prime, GE Healthcare, UK). During this
chromatography step, soluble protein fractions were loaded onto
Ni-NTA agarose resin column (GE Healthcare, UK) at the flow rate of
1 mL/min. The column was washed with a washing buffer (20 mM
Iris-Cl pH8.0, 300 mM NaCl, 20 mM imidazole, 1.times. protease
inhibitor cocktail) and the bound protein was eluted at the flow
rate of 0.5 ml/min with an elution buffer (20 mM Iris-Cl pH8.0, 300
mM NaCl, 250 mM imidazole, 1.times. protease inhibitor cocktail).
The pooled eluted fraction was concentrated and dialyzed against
storage buffer (50 mM Tris-HCl, pH8.0, 200 mM KCl, 0.1 mM EDTA, 1
mM DTT, 0.5 mM PMSF, 20% Glycerol). Protein concentration was
quantitated by Bradford assay (Biorad, Hercules, Calif.) and purity
was analyzed by SDS-PAGE using bovine serum albumin as the
control.
[0226] 5-4. Conjugation of Cas9 to 9R4L
[0227] 1 mg Cas9 protein diluted in PBS at the concentration of 1
mg/mL and 50 .mu.g of maleimide-9R4L peptide in 25 .mu.L DW
(Peptron, Korea) were gently mixed using a rotor at room
temperature for 2 hrs and at 4.degree. C. overnight. To remove
unconjugated maleimide-9R4L, the samples were dialyzed using 50 kD
a molecular weight cutoff membrane against of DPBS (pH 7.4) at
4.degree. C. for 24 hrs. Cas9-9R4L protein was collected from the
dialysis membrane and the protein amount was determined using
Bradford assay.
[0228] 5-5. Preparation of sgRNA-9R4L
[0229] sgRNA (1 .mu.g) was gently added to various amounts of
C9R4LC peptide (ranging from 1 to 40 weight ratio) in 100 .mu.l of
DPBS (pH 7.4). This mixture was incubated at room temperature for
30 mins and diluted to 10 folds using RNAse-free deionized water.
The hydrodynamic diameter and z-potential of the formed
nanoparticles were measured using dynamic light scattering
(Zetasizer-nano analyzer ZS; Malvern instruments, Worcestershire,
UK).
[0230] 5-6. Cas9 Protein and sgRNA Treatments
[0231] Cas9-9R4L and sgRNA-C9R4LC were treated to the cells as
follows: 1 .mu.g of sgRNA and 15 .mu.g of C9R4LC peptide were added
to 250 mL of OPTIMEM medium and incubated at room temperature for
30 mins. At 24 hrs after seeding, cells were washed with OPTIMEM
medium and treated with sgRNA-C9R4LC complex for 4 hrs at
37.degree. C. Cells were washed again with OPTIMEM medium and
treated with Cas9-9R4L for 2 hrs at 37.degree. C. After treatment,
culture media was replaced with serum-containing complete medium
and incubated at 37.degree. C. for 24 hrs before the next
treatment. Same procedure was followed for multiple treatments of
Cas9 and sgRNA for three consecutive days.
[0232] 5-7. Cas9-9R4L and sgRNA-9R4L can Edit Endogenous Genes in
Cultured Mammalian Cells without the Use of Additional Delivery
Tools
[0233] To determine whether Cas9-9R4L and sgRNA-9R4L can edit
endogenous genes in cultured mammalian cells without the use of
additional delivery tools, we treated 293 cells with Cas9-9R4L and
sgRNA-9R4L targeting the CCR5 gene and analyzed the genomic DNA.
T7E1 assay showed that 9% of CCR5 gene was disrupted in cells
treated with both Cas9-9R4L and sgRNA-9R4L and that the CCR5 gene
disruption was not observed in control cells including those
untreated, treated with either Cas9-9R or sgRNA-9R4L, or treated
with both unmodified Cas-9 and sgRNA (FIG. 13), suggesting that the
treatment with Cas9-9R4L protein and sgRNA conjugated with 9R4L,
but not unmodified Cas9 and sgRNA, can lead to efficient genome
editing in mammalian cells.
Example 6: Control of Off-Target Mutation According to Guide RNA
Structure
[0234] Recently, three groups reported that RGENs had off-target
effects in human cells. To our surprise, RGENs induced mutations
efficiently at off-target sites that differ by 3 to 5 nucleotides
from on-target sites. We noticed, however, that there were several
differences between our RGENs and those used by others. First, we
used dualRNA, which is crRNA plus tracrRNA, rather than
single-guide RNA (sgRNA) that is composed of essential portions of
crRNA and tracrRNA. Second, we transfected K562 cells (but not HeLa
cells) with synthetic crRNA rather than plasmids encoding crRNA.
HeLa cells were transfected with crRNA-encoding plasmids. Other
groups used sgRNA-encoding plasmids. Third, our guide RNA had two
additional guanine nucleotides at the 5' end, which are required
for efficient transcription by T7 polymerase in vitro. No such
additional nucleotides were included in the sgRNA used by others.
Thus, the RNA sequence of our guide RNA can be shown as
5'-GGX.sub.20, whereas 5'-GX.sub.19, in which X.sub.20 or GX.sub.19
corresponds to the 20-bp target sequence, represents the sequence
used by others. The first guanine nucleotide is required for
transcription by RNA polymerase in cells. To test whether
off-target RGEN effects can be attributed to these differences, we
chose four RGENs that induced off-target mutations in human cells
at high frequencies (13). First, we compared our method of using in
vitro transcribed dualRNA with the method of transfecting
sgRNA-encoding plasmids in K562 cells and measured mutation
frequencies at the on-target and off-target sites via the T7E1
assay. Three RGENs showed comparable mutation frequencies at
on-target and off-target sites regardless of the composition of
guide RNA. Interestingly, one RGEN (VEFGA site 1) did not induce
indels at one validated off-target site, which differs by three
nucleotides from the on-target site (termed OT1-11, FIG. 14), when
synthetic dualRNA was used. But the synthetic dualRNA did not
discriminate the other validated off-target site (OT1-3), which
differs by two nucleotides from the on-target site.
[0235] Next, we tested whether the addition of two guanine
nucleotides at the 5' end of sgRNA could make RGENs more specific
by comparing 5'-GGX.sub.20 (or 5'-GGGX.sub.19) sgRNA with
5'-GX.sub.19 sgRNA. Four GX.sub.19 sgRNAs complexed with Cas9
induced indels equally efficiently at on-target and off-target
sites, tolerating up to four nucleotide mismatches. In sharp
contrast, GGX.sub.20 sgRNAs discriminated off-target sites
effectively. In fact, the T7E1 assay barely detected RGEN-induced
indels at six out of the seven validated off-target sites when we
used the four GGX.sub.20 sgRNAs (FIG. 15). We noticed, however,
that two GGX.sub.20 sgRNAs (VEGFA sites 1 and 3) were less active
at on-target sites than were the corresponding GX.sub.19 sgRNAs.
These results show that the extra nucleotides at the 5' end can
affect mutation frequencies at on-target and off-target sites,
perhaps by altering guide RNA stability, concentration, or
secondary structure.
[0236] These results suggest that three factors-the use of
synthetic guide RNA rather than guide RNA-encoding plasmids,
dualRNA rather than sgRNA, and GGX.sub.20 sgRNA rather than
GX.sub.19 sgRNA-have cumulative effects on the discrimination of
off-target sites.
Example 7: Paired Cas9 Nickases
[0237] In principle, single-strand breaks (SSBs) cannot be repaired
by error-prone NHEJ but still trigger high fidelity
homology-directed repair (HDR) or base excision repair. But
nickase-induced targeted mutagenesis via HDR is much less efficient
than is nuclease-induced mutagenesis. We reasoned that paired Cas9
nickases would produce composite DSBs, which trigger DNA repair via
NHEJ or HDR, leading to efficient mutagenesis (FIG. 16A).
Furthermore, paired nickases would double the specificity of
Cas9-based genome editing.
[0238] We first tested several Cas9 nucleases and nickases designed
to target sites in the AAVS1 locus (FIG. 16B) in vitro via
fluorescent capillary electrophoresis. Unlike Cas9 nucleases that
cleaved both strands of DNA substrates, Cas9 nickases composed of
guide RNA and a mutant form of Cas9 in which a catalytic aspartate
residue is changed to an alanine (D10A Cas9) cleaved only one
strand, producing site-specific nicks (FIG. 16C,D). Interestingly,
however, some nickases (AS1, AS2, AS3, and S6 in FIG. 17A) induced
indels at target sites in human cells, suggesting that nicks can be
converted to DSBs, albeit inefficiently, in vivo. Paired Cas9
nickases producing two adjacent nicks on opposite DNA strands
yielded indels at frequencies that ranged from 14% to 91%,
comparable to the effects of paired nucleases (FIG. 17A). The
repair of two nicks that would produce 5' overhangs led to the
formation of indels much more frequently than those producing 3'
overhangs at three genomic loci (FIG. 17A and FIG. 18). In
addition, paired nickases enabled targeted genome editing via
homology-directed repair more efficiently than did single nickases
(FIG. 19).
[0239] We next measured mutation frequencies of paired nickases and
nucleases at off-target sites using deep sequencing. Cas9 nucleases
complexed with three sgRNAs induced off-target mutations at six
sites that differ by one or two nucleotides from their
corresponding on-target sites with frequencies that ranged from
0.5% to 10% (FIG. 17B). In contrast, paired Cas9 nickases did not
produce indels above the detection limit of 0.1% at any of the six
off-target sites. The S2 Off-1 site that differs by a single
nucleotide at the first position in the PAM (i.e., N in NGG) from
its on-target site can be considered as another on-target site. As
expected, the Cas9 nuclease complexed with the S2 sgRNA was equally
efficient at this site and the on-target site. In sharp contrast,
D10A Cas9 complexed with the S2 and AS2 sgRNAs discriminated this
site from the on-target site by a factor of 270 fold. This paired
nickase also discriminated the AS2 off-target sites (Off-1 and
Off-9 in FIG. 17B) from the on-target site by factors of 160 fold
and 990 fold, respectively.
Example 8: Chromosomal DNA Splicing Induced by Paired Cas9
Nickases
[0240] Two concurrent DSBs produced by engineered nucleases such as
ZFNs and TALENs can promote large deletions of the intervening
chromosomal segments has reported. We tested whether two SSBs
induced by paired Cas9 nickases can also produce deletions in human
cells. We used PCR to detect deletion events and found that seven
paired nickases induced deletions of up to 1.1-kbp chromosomal
segments as efficiently as paired Cas9 nucleases did (FIG. 20A,B).
DNA sequences of the PCR products confirmed the deletion events
(FIG. 20C). Interestingly, the sgRNA-matching sequence remained
intact in two out of seven deletion-specific PCR amplicons
(underlined in FIG. 20C). In contrast, Cas9 nuclease pairs did not
produce sequences that contained intact target sites. This finding
suggests that two distant nicks were not converted to two separate
DSBs to promote deletions of the intervening chromosomal segment.
In addition, it is unlikely that two nicks separated by more than a
100 bp can produce a composite DSB with large overhangs under
physiological conditions because the melting temperature is very
high.
[0241] We propose that two distant nicks are repaired by strand
displacement in a head-to-head direction, resulting in the
formation of a DSB in the middle, whose repair via NHEJ causes
small deletions (FIG. 20D). Because the two target sites remain
intact during this process, nickases can induce SSBs again,
triggering the cycle repeatedly until the target sites are deleted.
This mechanism explains why two offset nicks producing 5' overhangs
but not those producing 3' overhangs induced indels efficiently at
three loci.
[0242] We then investigated whether Cas9 nucleases and nickases can
induce unwanted chromosomal translocations that result from NHEJ
repair of on-target and off-target DNA cleavages (FIG. 21A). We
were able to detect translocations induced by Cas9 nucleases using
PCR (FIG. 21B, C). No such PCR products were amplified using
genomic DNA isolated from cells transfected with the plasmids
encoding the AS2+S3 Cas9 nickase pair. This result is in line with
the fact that both AS2 and S3 nickases, unlike their corresponding
nucleases, did not produce indels at off-target sites (FIG.
17B).
[0243] These results suggest that paired Cas9 nickases allow
targeted mutagenesis and large deletions of up to 1-kbp chromosomal
segments in human cells. Importantly, paired nickases did not
induce indels at off-target sites at which their corresponding
nucleases induce mutations. Furthermore, unlike nucleases, paired
nickases did not promote unwanted translocations associated with
off-target DNA cleavages. In principle, paired nickases double the
specificity of Cas9-mediated mutagenesis and will broaden the
utility of RNA-guided enzymes in applications that require precise
genome editing such as gene and cell therapy. One caveat to this
approach is that two highly active sgRNAs are needed to make an
efficient nickase pair, limiting targetable sites. As shown in this
and other studies, not all sgRNAs are equally active. When single
clones rather than populations of cells are used for further
studies or applications, the choice of guide RNAs that represent
unique sequences in the genome and the use of optimized guide RNAs
would suffice to avoid off-target mutations associated with Cas9
nucleases. We propose that both Cas9 nucleases and paired nickases
are powerful options that will facilitate precision genome editing
in cells and organisms.
Example 9: Genotyping with CRISPR/Cas-Derived RNA-Guided
Endonucleases
[0244] Next, We reasoned that RGENs can be used in Restriction
fragment length polymorphism (RFLP) analysis, replacing
conventional restriction enzymes. Engineered nucleases including
RGENs induce indels at target sites, when the DSBs caused by the
nucleases are repaired by the error-prone non-homologous
end-joining (NHEJ) system. RGENs that are designed to recognize the
target sequences cannot cleave mutant sequences with indels but
will cleave wildtype target sequences efficiently.
[0245] 9-1. RGEN Components
[0246] crRNA and tracrRNA were prepared by in vitro transcription
using MEGA shortcript T7 kit (Ambion) according to the
manufacturer's instruction. Transcribed RNAs were resolved on a 8%
denaturing urea-PAGE gel. The gel slice containing RNA was cut out
and transferred to elution buffer. RNA was recovered in
nuclease-free water followed by phenol:chloroform extraction,
chloroform extraction, and ethanol precipitation. Purified RNA was
quantified by spectrometry. Templates for crRNA were prepared by
annealing an oligonucleotide whose sequence is shown as
5'-GAAATTAATACGACTCACTATAGGX.sub.20GTTTTAGAGCTATGCTGTTTTG-3'(SEQ ID
NO: 76), in which X.sub.20 is the target sequence, and its
complementary oligonucleotide. The template for tracrRNA was
synthesized by extension of forward and reverse oligonucleotides
(5'-GAAATTAATACGACTCACTATAGGAACCATTCAAAACAGCATAGCAAGTTAAAATAAG
GCTAGTCCG-3' (SEQ ID NO: 77) and
5'-AAAAAAAGCACCGACTCGGTGCCACTTTTTCAAGTTGATAACGGACTAGCCTTATTTTA
ACTTGCTATG-3' (SEQ ID NO: 78)) using Phusion polymerase (New
England Biolabs).
[0247] 9-2. Recombinant Cas9 Protein Purification
[0248] The Cas9 DNA construct used in our previous Example, which
encodes Cas9 fused to the His6-tag at the C terminus, was inserted
in the pET-28a expression vector. The recombinant Cas9 protein was
expressed in E. coli strain BL21 (DE3) cultured in LB medium at
25.degree. C. for 4 hour after induction with 1 mM IPTG. Cells were
harvested and resuspended in buffer containing 20 mM Tris PH 8.0,
500 mM NaCl, 5 mM immidazole, and 1 mM PMSF. Cells were frozen in
liquid nitrogen, thawed at 4.degree. C., and sonicated. After
centrifugation, the Cas9 protein in the lysate was bound to Ni-NTA
agarose resin (Qiagen), washed with buffer containing 20 mM Tris pH
8.0, 500 mM NaCl, and 20 mM immidazole, and eluted with buffer
containing 20 mM Tris pH 8.0, 500 mM NaCl, and 250 mM immidazole.
Purified Cas9 protein was dialyzed against 20 mM HEPES (pH 7.5),
150 mM KCl, 1 mM DTT, and 10% glycerol and analyzed by
SDS-PAGE.
[0249] 9-3. T7 Endonuclease I Assay
[0250] The T7E1 assay was performed as following. In brief, PCR
products amplified using genomic DNA were denatured at 95.degree.
C., reannealed at 16.degree. C., and incubated with 5 units of T7
Endonuclease I (New England BioLabs) for 20 min at 37.degree. C.
The reaction products were resolved using 2 to 2.5% agarose gel
electrophoresis.
[0251] 9-4. RGEN-RFLP Assay
[0252] PCR products (100-150 ng) were incubated for 60 min at
37.degree. C. with optimized concentrations (Table 10) of Cas9
protein, tracrRNA, crRNA in 10 .mu.l NEB buffer 3 (1.times.). After
the cleavage reaction, RNase A (4 .mu.g) was added, and the
reaction mixture was incubated for 30 min at 37.degree. C. to
remove RNA. Reactions were stopped with 6.times. stop solution
buffer containing 30% glycerol, 1.2% SDS, and 100 mM EDTA. Products
were resolved with 1-2.5% agarose gel electrophoresis and
visualized with EtBr staining.

[0253] 9-5. Plasmid Cleavage Assay
[0254] Restriction enzyme-treated linearized plasmid (100 ng) was
incubated for 60 min at 37.degree. C. with Cas9 protein (0.1
.mu.g), tracrRNA (60 ng), and crRNA (25 ng) in 10 .mu.l NEB 3
buffer (1.times.). Reactions were stopped with 6.times. stop
solution containing 30% glycerol, 1.2% SDS, and 100 mM EDTA.
Products were resolved with 1% agarose gel electrophoresis and
visualized with EtBr staining.
[0255] 9-6. Strategy of RFLP
[0256] New RGENs with desired DNA specificities can be readily
created by replacing crRNA; no de novo purification of custom
proteins is required once recombinant Cas9 protein is available.
Engineered nucleases, including RGENs, induce small insertions or
deletions (indels) at target sites when the DSBs caused by the
nucleases are repaired by error-prone non-homologous end-joining
(NHEJ). RGENs that are designed to recognize the target sequences
cleave wild-type sequences efficiently but cannot cleave mutant
sequences with indels (FIG. 22).
[0257] We first tested whether RGENs can differentially cleave
plasmids that contain wild-type or modified C4BPB target sequences
that harbor 1- to 3-base indels at the cleavage site. None of the
six plasmids with these indels were cleaved by a C4BPB-specific
RGENS composed of target-specific crRNA, tracrRNA, and recombinant
Cas9 protein (FIG. 23). In contrast, the plasmid with the intact
target sequence was cleaved efficiently by this RGEN.
[0258] 9-7. Detection of Mutations Induced by the Same RGENs Using
RGEN-Mediated RFLP
[0259] Next, to test the feasibility of RGEN-mediated RFLP for
detection of mutations induced by the same RGENs, we utilized
gene-modified K562 human cancer cell clones established using an
RGEN targeting C4BPB gene (Table 12).
TABLE-US-00012 TABLE 12 Target sequence of RGENs used in this study
Gene Target sequence SEQ ID NO human C4BPB AATGACCACTACATCCTCAAGGG
104 mouse Pibf1 AGATGATGTCTCATCATCAGAGG 105
[0260] C4BPB mutant clones used in this study have various
mutations ranging from 94 by deletion to 67 by insertion (FIG.
24A). Importantly, all mutations occurred in mutant clones resulted
in the loss of RGEN target site. Among 6 C4BPB clones analyzed, 4
clones have both wildtype and mutant alleles (+/-) and 2 clones
have only mutant alleles (-/-).
[0261] The PCR products spanning the RGEN target site amplified
from wildtype K562 genomic DNA were digested completely by the RGEN
composed of target-specific crRNA, tracrRNA, and recombinant Cas9
protein expressed in and purified from E. coli (FIG. 24B/Lane 1).
When the C4BPB mutant clones were subjected to RFLP analysis using
the RGEN, PCR amplicons of +/- clones that contained both wildtype
and mutant alleles were partially digested, and those of -/- cloned
that did not contain the wildtype allele were not digested at all,
yielding no cleavage products corresponding to the wildtype
sequence (FIG. 24B). Even a single-base insertion at the target
site blocked the digestion (#12 and #28 clones) of amplified mutant
alleles by the C4BPB RGEN, showing the high specificity of
RGEN-mediated RFLP. We subjected the PCR amplicons to the
mismatch-sensitive T7E1 assay in parallel (FIG. 24B). Notably, the
T7E1 assay was not able to distinguish -/- clones from +/- clones.
To make it matters worse, the T7E1 assay cannot distinguish
homozygous mutant clones that contain the same mutant sequence from
wildtype clones, because annealing of the same mutant sequence will
form a homoduplex. Thus, RGEN-mediated RFLP has a critical
advantage over the conventional mismatch-sensitive nuclease assay
in the analysis of mutant clones induced by engineered nucleases
including ZFNs, TALENs and RGENs.
[0262] 9-8. Quantitative Assay for RGEN-RFLP Analysis
[0263] We also investigated whether RGEN-RFLP analysis is a
quantitative method. Genomic DNA samples isolated from the C4BPB
null clone and the wild-type cells were mixed at various ratios and
used for PCR amplifications. The PCR products were subjected to
RGEN genotyping and the T7E1 assay in parallel (FIG. 25b). As
expected, DNA cleavage by the RGEN was proportional to the wild
type to mutant ratio. In contrast, results of the T7E1 assay
correlated poorly with mutation frequencies inferred from the
ratios and were inaccurate, especially at high mutant %, a
situation in which complementary mutant sequences can hybridize
with each other to form homoduplexes.
[0264] 9-9. Analysis of Mutant Mouse Founders Using a RGEN-Mediated
RFLP Genotyping
[0265] We also applied RGEN-mediated RFLP genotyping (RGEN
genotyping in short) to the analysis of mutant mouse founders that
had been established by injection of TALENs into mouse one-cell
embryos (FIG. 26A). We designed and used an RGEN that recognized
the TALEN target site in the Pibf1 gene (Table 10). Genomic DNA was
isolated from a wildtype mouse and mutant mice and subjected to
RGEN genotyping after PCR amplification. RGEN genotyping
successfully detected various mutations, which ranged from one to
27-bp deletions (FIG. 26B). Unlike the T7E1 assay, RGEN genotyping
enabled differential detection of +/- and -/- founder.
[0266] 9-10. Detection of Mutations Induced in Human Cells by a
CCR5-Specific ZFN Using RGENs
[0267] In addition, we used RGENs to detect mutations induced in
human cells by a CCR5-specific ZFN, representing yet another class
of engineered nucleases (FIG. 27). These results show that RGENs
can detect mutations induced by nucleases other than RGENs
themselves. In fact, we expect that RGENs can be designed to detect
mutations induced by most, if not all, engineered nucleases. The
only limitation in the design of an RGEN genotyping assay is the
requirement for the GG or AG (CC or CT on the complementary strand)
dinucleotide in the PAM sequence recognized by the Cas9 protein,
which occurs once per 4 bp on average. Indels induced anywhere
within the seed region of several bases in crRNA and the PAM
nucleotides are expected to disrupt RGEN-catalyzed DNA cleavage.
Indeed, we identified at least one RGEN site in most (98%) of the
ZFN and TALEN sites.
[0268] 9-11. Detection of Polymorphisms or Variations Using
RGEN
[0269] Next, we designed and tested a new RGEN that targets a
highly polymorphic locus, HLA-B, that encodes Human Leukocyte
Antigen B (a.k.a. MHC class I protein) (FIG. 28). HeLa cells were
transfected with RGEN plasmids, and the genomic DNA was subjected
to T7E1 and RGEN-RFLP analyses in parallel. T7E1 produced false
positive bands that resulted from sequence polymorphisms near the
target site (FIG. 25c). As expected, however, the same RGEN used
for gene disruption cleaved PCR products from wild-type cells
completely but those from RGEN-transfected cells partially,
indicating the presence of RGEN-induced indels at the target site.
This result shows that RGEN-RFLP analysis has a clear advantage
over the T7E1 assay, especially when it is not known whether target
genes have polymorphisms or variations in cells of interest.
[0270] 9-12. Detection of Recurrent Mutations Found in Cancer and
Naturally-Occurring Polymorphisms Through RGEN-RFLP Analysis
[0271] RGEN-RFLP analysis has applications beyond genotyping of
engineered nuclease-induced mutations. We sought to use RGEN
genotyping to detect recurrent mutations found in cancer and
naturally-occurring polymorphisms. We chose the human colorectal
cancer cell line, HCT116, which carries a gain-of-function 3-bp
deletion in the oncogenic CTNNB1 gene encoding beta-catenin. PCR
products amplified from HCT116 genomic DNA were cleaved partially
by both wild-type-specific and mutant-specific RGENs, in line with
the heterozygous genotype in HCT116 cells (FIG. 29a). In sharp
contrast, PCR products amplified from DNA from HeLa cells harboring
only wild-type alleles were digested completely by the
wild-type-specific RGEN and were not cleaved at all by the
mutation-specific RGEN.
[0272] We also noted that HEK293 cells harbor the 32-bp deletion
(de132) in the CCR5 gene, which encodes an essential co-receptor of
HIV infection: Homozygous de132 CCR5 carriers are immune to HIV
infection. We designed one RGEN specific to the de132 allele and
the other to the wild-type allele. As expected, the
wild-type-specific RGEN cleaved the PCR products obtained from
K562, SKBR3, or HeLa cells (used as wild-type controls) completely
but those from HEK293 cells partially (FIG. 30a), confirming the
presence of the uncleavable de132 allele in HEK293 cells.
Unexpectedly, however, the de132-specific RGEN cleaved the PCR
products from wild-type cells as efficiently as those from HEK293
cells. Interestingly, this RGEN had an off-target site with a
single-base mismatch immediately downstream of the on-target site
(FIG. 30). These results suggest that RGENs can be used to detect
naturally-occurring indels but cannot distinguish sequences with
single nucleotide polymorphisms or point mutations due to their
off-target effects.
[0273] To genotype oncogenic single-nucleotide variations using
RGENs, we attenuated RGEN activity by employing a single-base
mismatched guide RNA instead of a perfectly-matched RNA. RGENs that
contained the perfectly-matched guide RNA specific to the wild-type
sequence or mutant sequence cleaved both sequences (FIGS. 31a and
32a). In contrast, RGENs that contained a single-base mismatched
guide RNA distinguished the two sequences, enabling genotyping of
three recurrent oncogenic point mutations in the KRAS, PIK3CA, and
IDH1 genes in human cancer cell lines (FIG. 29b and FIGS. 33a, b).
In addition, we were able to detect point mutations in the BRAF and
NRAS genes using RGENs that recognize the NAG PAM sequence (FIGS.
33c, d). We believe that we can use RGEN-RFLP to genotype almost
any, if not all, mutations or polymorphisms in the human and other
genomes.
[0274] The above data proposes RGENs as providing a platform to use
simple and robust RFLP analysis for various sequence variations.
With high flexibility in reprogramming target sequence, RGENs can
be used to detect various genetic variations (single nucleotide
variations, small insertion/deletions, structural variations) such
as disease-related recurring mutations, genotypes related to
drug-response by a patient and also mutations induced by engineered
nucleases in cells. Here, we used RGEN genotyping to detect
mutations induced by engineered nucleases in cells and animals. In
principle, one could also use RGENs that will specifically detect
and cleave naturally-occurring variations and mutations.
