Methods for detecting, diagnosing and treating human renal cell
carcinoma
Abstract
Gene expression profiling and hierarchical clustering analysis
readily identify differential gene expressions in normal renal
epithelial cells and renal cell carcinomas. Genes identified by
this analysis would be useful for diagnosis, prognosis and
development of targeted therapy for the prevention and treatment of
conventional renal cell carcinoma.

Description
CROSS-REFERENCE TO RELATED APPLICATION
[0001] This non-provisional patent application claims benefit of
provisional patent application 60/502,038, filed Sep. 10, 2003, and
60/539,838, filed Jan. 28, 2004, now abandoned.
BACKGROUND OF THE INVENTION
[0002] 1. Field of the Invention
[0003] The present invention relates generally to the field of
cancer research. More specifically, the present invention relates
to gene expression profiling for human renal cell carcinoma.
[0004] 2. Description of the Related Art
[0005] Renal cell carcinoma (RCC) represents a major health issue.
The American Cancer Society predicts 31,900 new cases will be
diagnosed in the United States alone in the year 2003, with 11,900
people dying of the disease. When clinically localized or even
locally advanced, renal cell carcinoma can be surgically resected
for cure using a variety of approaches. With metastatic
progression, however, renal cell carcinoma is incurable, and
existing systemic therapies are largely ineffective in impacting
disease response or patient survival. The lack of effective
systemic therapy for metastatic renal cell carcinoma is, in part,
due to a fundamental lack of understanding of the molecular events
that result in cellular transformation, carcinogenesis, and
progression in human kidney.
[0006] The advent of gene array technology has allowed
classification of disease states at molecular level by examining
changes in all mRNAs expressed in cells or tissues. Gene expression
fingerprints representing large numbers of genes may allow precise
and accurate grouping of renal cell carcinoma. Moreover, large
scale gene expression analysis have the potential of identifying a
number of differentially expressed genes in renal cell carcinoma
compare to normal renal epithelial cells. These genes or markers
may further be tested for clinical utility in the diagnosis and
treatment of renal cell carcinoma.
[0007] Thus, the identification of novel renal cell carcinoma
markers to be used for detection, diagnosis and development of
effective therapy against the disease remains a high priority. The
prior art is deficient in understanding the molecular differences
between renal cell carcinoma and normal renal epithelium. The
present invention fulfills this need in the art by providing gene
expression profiling for these two types of tissues.
SUMMARY OF THE INVENTION
[0008] The present invention identifies genes with a differential
pattern of expression between different subtypes of renal cell
carcinomas (RCC) and normal renal epithelium. These genes and their
products can be used to develop novel diagnostic and therapeutic
markers for the treatment of renal cell carcinomas.
[0009] Genomic profiling of conventional renal cell carcinoma
tissues and patient-matched normal kidney tissue samples was
carried out using stringent statistical analyses (ANOVA with full
Bonferroni corrections). Subtypes of renal cell carcinoma include
stage I, II, III, and IV (reflecting differences in tumor size,
lymph node and organ metastasis), stage I papillary renal cell
carcinoma, and benign oncocytoma. Hierarchical clustering of the
expression data readily distinguished normal tissue from renal cell
carcinomas. The identified genes were verified by real-time PCR and
immunohistochemical analyses.
[0010] Different subtypes of conventional renal cell carcinomas can
be diagnosed either by drawing blood and identifying secreted gene
products specific to renal cell carcinoma or by doing a biopsy of
the tissue and then identify specific genes that are altered when
renal cell carcinoma is present. An example of when this may be
especially important is in distinguishing the deadly conventional
renal cell carcinomas (account for 85% of all renal cell
carcinomas) from renal oncocytoma (benign renal cell carcinoma) as
well as identifying the histologic subtypes of papillary and
sarcomatoid renal cell carcinoma. Identification of specific genes
will also help in determining which patients will have a good
prognosis verses that of a poor prognosis. In addition, subsets of
genes identified in the present invention can be developed as
targets for therapies that could cure, prevent, or stabilize the
disease. Thus, results from the present invention could be used for
diagnosis, prognosis, and development of therapies to treat or
prevent renal cell carcinoma.
[0011] In one embodiment, there are provided methods of detecting
conventional or clear cell renal cell carcinoma based on
over-expression and/or down-regulation of a number of genes
disclosed herein. In another embodiment, conventional or clear cell
renal cell carcinoma is detected based on decreased expression of
type III TGF-b receptor.
[0012] In yet another embodiment, there are provided methods of
detecting stage I conventional or clear cell renal cell carcinoma
based on over-expression and/or down-regulation of a number of
genes disclosed herein. The present invention also provides methods
of detecting stage II conventional or clear cell renal cell
carcinoma based on over-expression and/or down-regulation of a
number of genes disclosed herein.
[0013] The present invention also provides methods of detecting
papillary renal cell carcinoma or benign oncocytoma based on
over-expression and/or down-regulation of a number of genes
disclosed herein.
[0014] In another embodiment, there is provided a method of
targeting conventional or clear cell renal cell carcinoma cells
based on generating antibodies or small molecules directed against
a cell surface molecule over-expressed in conventional renal cell
carcinoma cells.
[0015] In yet another embodiment, there is provided a method of
treating conventional or clear cell renal cell carcinoma by
replacing down-regulated tumor suppressor gene in conventional
renal cell carcinoma.
[0016] Other and further aspects, features, and advantages of the
present invention will be apparent from the following description
of the presently preferred embodiments of the invention. These
embodiments are given for the purpose of disclosure.

DETAILED DESCRIPTION OF THE INVENTION
[0039] High-throughput technologies for assaying gene expression,
such as high-density oligonucleotide and cDNA microarrays, offer
the potential to identify clinically relevant genes differentially
expressed between normal and tumor cells. The present invention
discloses a genome-wide examination of differential gene expression
between renal cell carcinomas (RCC) and normal renal epithelial
cells.
[0040] Currently, there are no proven molecular markers useful
clinically for the diagnosis, staging, or prognosis of sporadic
renal cell carcinoma. The present invention detects genes that have
differential expression between renal cell carcinomas and normal
renal epithelial cells. The known function of some of these genes
may provide insight into the biology of renal cell carcinomas while
others may prove to be useful as diagnostic or therapeutic markers
against renal cell carcinomas. Subtypes of renal cell carcinomas
disclosed herein include stage I, II, III, and IV renal cell
carcinomas (reflecting differences in tumor size, lymph node and
organ metastasis), stage I papillary renal cell carcinoma, and
benign oncocytoma.
[0041] The present invention provides methods of detecting
conventional renal cell carcinoma based on determining the
expression level of a number of genes that are found to have 2-fold
or higher differential expression levels between tumor and normal
tissue. In general, biological samples (e.g. tissue samples, serum
samples, urine samples, saliva samples, blood samples or biopsy
samples) are obtained from the individual to be tested and gene
expression at RNA or protein level is compared to that in normal
tissue. The normal tissue samples can be obtained from the same
individual who is to be tested for renal cell carcinoma. It will be
obvious to one of ordinary skill in the art that gene expression
can be determined by DNA microarray and hierarchical cluster
analysis, real-time PCR, RT-PCR, or northern analysis, whereas
secreted gene products can be measured in blood samples by standard
procedures.
[0042] In one embodiment, there is provided a method of detecting
conventional or clear cell renal cell carcinoma based on
differential expression of one or more of the following genes or
proteins: TGF-b1, TGF-a, adrenomedulin, fibroblast growth factor 2
(FGF2), vascular epidermal growth factor (VEGF), osteonectin,
follistatin like-3, inhibin beta A, spondin 2, chemokine X cytokine
receptor 4 (CXCR4), fibronectin, neuropilin 1, frizzled homolog 1,
insulin-like growth factor binding protein 3, laminin alpha 3,
integrin beta 2, semaphorins 6A, semaphorins 5B, semaphorins 3B,
caspase 1, sprouty 1, CDH16, PCDH9, compliment component 1-beta,
compliment component 1-alpha, compliment component 1-gamma, CD53,
CDW52, CD163, CD14, CD3Z, CD24, RAP1, angiopoietin 2, cytokine knot
secreted protein, MAPKKKK4, 4-hydroxyphenylpyruvate dioxygenase,
pyruvate carboxyknase 2, 11-beta-hydroxysteroid dehydrogenase 2,
GAS1, CDKN1, nucleolar protein 3, interferon induced protein 44,
NR3C1, vitamin D receptor, hypothetical protein FLJ14957 (Affy#
225817_at), metallothionein 2A, metallothionein-If gene,
metallothionein 1H, secreted frizzled related protein 1, connective
tissue growth factor, and epidermal growth factor.
[0043] In another embodiment, there is provided a method of
detecting conventional renal cell carcinoma by examining the
expression level of type III TGF-b receptor, wherein decreased
expression of type III TGF-b receptor indicates the presence of
renal cell carcinoma. In general, the expression level of type III
TGF-b receptor can be determined at the mRNA or protein level.
[0044] The present invention also provides methods of detecting
stage I conventional renal cell carcinoma, stage II conventional
renal cell carcinoma, stage I papillary renal cell carcinoma, or
benign oncocytoma based on over-expression or down-regulation of a
number of genes identified in the present invention. The present
invention discloses a number of genes that are up- or
down-regulated specifically in these subtypes of renal cell
carcinoma. Determining the expression levels of these genes would
provide specific diagnosis for these different subtypes of renal
cell carcinoma.
[0045] For example, stage I conventional renal cell carcinoma can
be detected based on (i) over-expression of one or more genes
listed in Table 1, (ii) down-regulation of one or more genes listed
in Table 2, or (iii) over-expression of one or more genes listed in
Table 1 and down-regulation of one or more genes listed in Table 2.
Similarly, stage II conventional renal cell carcinoma can be
detected based on (i) over-expression of one or more genes listed
in Table 3, (ii) down-regulation of one or more genes listed in
Table 4, or (iii) over-expression of one or more genes listed in
Table 3 and down-regulation of one or more genes listed in Table
4.
[0046] The present invention also discloses a number of genes that
are up- or down-regulated in both stage I and stage II conventional
renal cell carcinoma (Tables 5 and 6 respectively). These genes
would also provide diagnosis for stage I or stage II conventional
renal cell carcinoma. Hence, stage I or stage II conventional renal
cell carcinoma can be detected based on (i) over-expression of one
or more genes listed in Table 5, or (ii) down-regulation of one or
more genes listed in Table 6.
[0047] In another embodiment, stage I papillary renal cell
carcinoma can be detected based on (i) over-expression of one or
more genes listed in Table 8, (ii) down-regulation of one or more
genes listed in Table 9, or (iii) over-expression of one or more
genes listed in Table 8 and down-regulation of one or more genes
listed in Table 9.
[0048] In yet another embodiment, benign oncocytoma can be detected
based on (i) over-expression of one or more genes listed in Table
10, (ii) down-regulation of one or more genes listed in Table 11,
or (iii) over-expression of one or more genes listed in Table 10
and down-regulation of one or more genes listed in Table 11.
[0049] In still yet another embodiment, there are provided methods
of utilizing genes over-expressed on the cell surface of renal
carcinoma tissue to develop antibodies or other small molecules for
the purpose of specifically targeting the renal tumor cells. The
present invention discloses a number of genes that are up-regulated
in stage I renal cell carcinoma (RCC), stage II RCC tumor, stage I
papillary RCC, and benign oncocytoma. Antibodies or small molecules
directed against proteins encoded by these genes can be linked with
a therapeutic drug to deliver drug to the tumor tissue, or be
linked with dye, nanoparticle or other imaging agents for cancer
imaging. Some of the novel genes identified herein for the first
time include, but are not limited to, the following genes:
calcitonin receptor-like (206331_at; 210815_s_at); receptor
(calcitonin) activity modifying protein 2 (RAMP2; 205779_at);
endothelin receptor type B (206701_x_at); beta 2 integrin
(202803_s_at); alpha 5 integrin (201389_at); chemokine X cytokine
receptor 4 (CXCR4); fibronectin; neuropilin 1 (212298_at;
210510_s_at); CD24; CD14; Cd163; CD53; Compliment Componenet
1-beta, 1-alpha, and 1-gamma; CDH4; integrin beta2; ADAM28; FK506
binding protein; collagen Valpha2; tumor necrosis factor receptor
superfamily, member 6; tumor necrosis factor receptor superfamily,
member 5; tumor necrosis factor (ligand) superfamily, member 13b;
tumor necrosis factor receptor superfamily, member 12A; and the FGF
receptor.
[0050] In another embodiment, there is provided a method of
treating conventional or clear cell renal cell carcinoma. The
method involves replacing tumor suppressor genes (e.g., via gene
therapy) whose expression is down-regulated in tumor tissues or
introducing a molecule that induces the down-regulated gene to be
re-expressed in the tumor. The present invention discloses a number
of genes that are down-regulated in stage I renal cell carcinoma
(RCC), stage II RCC tumor, stage I papillary RCC, and benign
oncocytoma. Some examples of down-regulated genes identified in
stage I and/or II RCC tumors include, but are not limited to,
CDKN1, secreted frizzled related protein 1, semaphoring 6D,
semaphoring 3B, CDH16, TNF alpha, calbindin D28, defensin beta1,
beta-catenin interacting protein 1, GAS1, vitamin D receptor,
Kruppel-like factor 15. This method of treatment can be combined
with other therapies to provide combinatorial therapy.
[0051] The genes that are found to have altered expression in stage
I and stage II renal cell carcinoma would also be useful for
determining patient prognosis. These genes or gene products (i.e.,
proteins) would have the unique characteristic of being altered in
tumor verses normal samples in a subset of patients. For example,
basic transcription element binding protein 1 is down-regulated in
7 out of 12 renal cell carcinoma tumors. Other examples include
CD164, decreased 5/12; Map kinase kinase kinase 7, increased 6/12;
Endoglin, increased 7/12; SERPIN A1, increased 6/12;
Metalloprotease 11 (MMP11), increased 7/12; Integrin 3 alpha,
increased 4/12; carbonic anhydrase II, decreased 7/12; protein
tyrosine kinase 2, increased 4/12; fibroblast growth factor 11,
increased 6/12; fibroblast growth factor 2, increased 7/12; VEGF B,
increased 5/12.
[0052] Moreover, the levels of change may be a useful determinant
of patient outcome and/or rationale for strategy of treatment
course. An example of this is found for chemokine (C-X-C motif)
ligand 14 (CXCL14, 222484_s_at). Six patients with stage I and six
patients with stage II renal cell carcinoma were analyzed by
genomic profiling. A patient with stage I renal cell carcinoma has
CXCL14 mRNA expression levels of 19862 and 24.49 in his normal
tissue and tumor tissue respectively. This patient would be
predicted to have a poor prognosis or poor response to therapy
based upon this result along with other gene predictors. On the
other hand, a patient with stage II RCC has CXCL14 mRNA expression
levels of 20435 and 18557 in his normal tissue and tumor tissue
respectively. This patient would be predicted to have a good
prognosis and good response to chemotherapy.
[0053] The following examples are given for illustrating various
embodiments of the invention and are not meant to limit the present
invention in any fashion. One skilled in the art will appreciate
readily that the present invention is well adapted to carry out the
objects and obtain the ends and advantages mentioned, as well as
those objects, ends and advantages inherent herein. Changes therein
and other uses which are encompassed within the spirit of the
invention as defined by the scope of the claims will occur to those
skilled in the art.
EXAMPLE 1
[0054] Tissue Banking
[0055] Renal tissue (normal and tumor) was transported to a sterile
hood on ice and under sterile conditions. Tissue was dissected
under the direction of a pathologist. The tissue was frozen in
liquid nitrogen for isolation of RNA, DNA, and protein or processed
to establish primary cell cultures. The tissue was fixed in
formalin for immunohistochemistry and in situ hybridization and
RNAlater (Ambion) for RNA isolation. Primary normal renal
epithelial (NRE) cell cultures were established using standard
collagenase/Dnase techniques to digest tissue and isolate single
cells. NREs were easily isolated and grew well in culture for up to
10 passages. These cells were further analyzed for homogeneity with
regard to epithelial population using appropriate
immunohistochemical markers such as vimentin, cytokeratin, and
megalin.
EXAMPLE 2
[0056] Genomic Gene Array and Microarray Data Analysis
[0057] Gene expression profiling was performed using Affymetrix
HU95A oligonucleotide gene arrays (>12,600 genes) or HG-U133
A&B GeneChip.RTM. oligonucleotide microarrays (33,000+ probe
sets). Total RNA (Trizol.RTM., Ambion) was extracted from
patient-matched normal renal cortex and tumor tissue from patients
diagnosed with local disease confined to the kidney. Alternatively,
the investigators analyzed metastatic disease defined by lesions in
lymph nodes, adrenal, or other organs. Data were analyzed by a
combination of two-dimensional ANOVA, Affymetrix MAS5.0.RTM., and
hierarchical cluster analysis using Spotfire.RTM.. Procedure that
were used to identify altered expression of large sets of genes, as
well as other issues concerning microarray analyses can be found in
a recent review article by Copland et al. (2003).
EXAMPLE 3
[0058] Real-Time PCR
[0059] Applied Biosystems' assays-by-design or assays-on-demand 20X
assay mix of primers and TaqMan.RTM. MGB probes (FAM.RTM.
dye-labeled) for all target genes and predeveloped 18S rRNA
(VIC.RTM. dye-labeled probe) TaqMan.RTM. assay reagent for internal
control were used for real-time PCR measurements. These assays were
designed to span exon-exon junctions so as not to detect genomic
DNA and an primers and probes sequences were searched against the
Celera database to confirm specificity. Validation experiments were
performed to test the efficiency of the target amplification and
the efficiency of the reference amplification. All absolute values
of the slope of log input amount versus DC.sub.T is less than
0.1.
[0060] Separate tubes (singleplex) for one-step RT-PCR was
performed with 50 ng RNA for both target genes and endogenous
controls using TaqMan.RTM. one-step RT-PCR master mix reagent kit
(Applied Biosystems). The cycling parameters for one-step RT-PCR
were: reverse transcription 48.degree. C. for 30 min, AmpliTaq.RTM.
activation 95.degree. C. for 10 min, denaturation 95.degree. C. for
15 s, and annealing/extension 60.degree. C. for 1 min (repeat 40
times) on ABI7000.RTM.. Duplicate C.sub.T values were analyzed with
Microsoft Excel.RTM. using the comparative C.sub.T(DDC.sub.T)
method as described by the manufacturer (Applied Biosystems). The
amount of target (2.sup.-DDCT) was obtained by normalizing to an
endogenous reference (18smRNA) and relative to a calibrator (normal
tissue).
EXAMPLE 4
[0061] Immunohistochemical Analyses of Protein Expression
[0062] For immunohistochemical analyses of type I TGF-b receptor
(TBR1), type II TGF-b receptor (TBR2), and type III TGF-b receptor
(TBR3) expression, patient-matched normal renal and tumor tissue
samples were fixed in 10% neutral-buffered formalin and embedded in
paraffin blocks. Consecutive sections were cut 5 um thick,
deparaffinized, hydrated, and immunostained using antibodies
recognizing human TBR1, TBR2, and TBR3 (1:100; Santa Cruz
Biotechnology). Biotinylated secondary antibody (1:600; Santa Cruz
Biotechnology) was detected using avidin-biotin-peroxidase
detection according to the manufacturer's instructions (Vectastatin
Elite ABC kit; Vector Lab). All slides were lightly counterstained
with hematoxylin before dehydration and mounting.
[0063] For cell lines, cells were plated on glass coverslips in
wells. Prior to the detection of TGF-b receptor expression as
described above, cells were fixed onto the coverslips with 3%
formalin.
EXAMPLE 5
[0064] Gene Expression Profiling of Renal Cell Carcinoma
[0065] Gene expression profiling was performed using Affymetrix
oligonucleotide gene arrays. RNA was extracted from patient-matched
normal renal cortical and tumor tissues from patients diagnosed
with localized and metastatic renal cell carcinoma. Data were
analyzed by a combination of two-dimensional ANOVA, Affymetrix
MAS5.0.RTM., and hierarchical cluster analysis using Spotfire.RTM.
(reviewed in Copland et al., 2003).
[0066] A primary goal of microarray analysis is to discover hidden
patterns of differential expression within a large data field.
Normal renal cortical and primary tumor tissue with no metastasis
were collected from patients diagnosed with local disease. Normal
tissue, primary tumor, and metastatic tissue were also collected
from patients diagnosed with metastatic disease. Comparison of
patient-matched normal and tumor tissue allowed for the discovery
of changes in mRNA levels between normal and tumor tissue, as well
as local and metastatic disease.
[0067] Heatmaps with two-way dendograms depicting genes
specifically altered in tumor tissue as compared to normal renal
cortex are shown in FIG. 1. FIG. 1A shows hierarchical clustering
of genes expressed in normal renal cortex verses stage I
conventional renal cell carcinoma. FIG. 1B shows hierarchical
clustering of genes expressed in normal renal cortex verses stage
II renal cell carcinoma. FIG. 1C shows hierarchical clustering of
genes selected from a Venn analysis in which the chosen genes were
expressed in common in both stage I and II at a 99% confidence
level.
[0068] TGF-b1, TGF-a and adrenomedulin mRNA levels were
up-regulated in all stages of renal cell carcinoma as compared to
normal tissue counterparts (FIGS. 2-4), whereas TGF-b2 and TGF-b3
mRNA levels were not altered between normal and tumor matched
samples (FIGS. 5-6).
[0069] Tumor suppressor gene Wilms Tumor 1 (WT1) was down-regulated
in all stages of renal cell carcinoma (FIG. 7). A small percentage
of tumor tissues demonstrated attenuated von Hippel Lindau mRNA
levels when compared to matched normal tissue (FIG. 8). Calbindin
mRNA was completely lost (FIG. 9) while MUC1 was greatly attenuated
in stage I renal cell carcinoma (FIG. 10).
[0070] The present analysis identifies 278 genes that were
up-regulated in stage I renal cell carcinoma, whereas 380 genes
were up-regulated in stage II renal cell carcinoma.
[0071] Among these genes, 82 were up-regulated in both stages I and
II renal cell carcinoma. One hundred fifty nine genes were
down-regulated in stage I renal cell carcinoma, whereas 195 genes
were down-regulated in stage II RCC. Among these genes, 82 were
down-regulated in both stage I and II renal cell carcinoma.
[0072] Genes over-expressed and down-regulated in stage I renal
cell carcinoma are listed in Table 1 and Table 2 respectively.
Genes over-expressed and down-regulated in stage II renal cell
carcinoma are listed in Table 3 and Table 4 respectively. Genes
over-expressed in both stage I and II renal cell carcinoma are
listed in Table 5. Genes down-regulated in both stage I and II
renal cell carcinoma are listed in Table 6.

EXAMPLE 6
[0078] Loss of TGF-b Receptor Expression Demonstrated by Gene Array
and Real-Time PCR in Renal Cell Carcinoma
[0079] Expression of type I TGF-b receptor (TBR1), type II TGF-b
receptor (TBR2), and type III TGF-b receptor (TBR3) mRNA were
compared in normal renal tissue, primary renal cell carcinoma
without metastasis, primary lesions of metastatic renal cell
carcinoma, and metastatic lesions. A summary of gene array analysis
was presented as average signal intensities in FIG. 11A
(mean.+-.standard error). The signal intensity for TBR1
(cross-hatched bars) was relatively low, although TBR1 was scored
as `Present` in all samples. No significant changes in TBR1
expression were observed. TBR2 (gray bars) was abundantly expressed
in normal epithelium and in primary lesions of nonmetastatic renal
cell carcinoma. TBR2 was significantly reduced in primary lesions
with metastatic disease (P<0.028 by ANOVA). TBR2 was even more
reduced in metastatic lesions. TBR3 expression was high in normal
epithelium, but was significantly reduced in each of the five
primary tumors with nonmetastatic disease (black bars). TBR3
expression was also reduced in primary tumors with metastatic
lesions and in metastatic lesions themselves.
[0080] These expression patterns were confirmed by real-time PCR
(Taqman.RTM.) in the 10 patients used for gene array analysis.
Means and standard errors for individual samples are shown in FIG.
11B. All data were normalized to 18S rRNA and calibrated to target
abundance in the paired normal tissues. TBR1 mRNA abundance did not
change (cross-hatched bars), consistent with the gene chip data.
TBR2 (gray bars) was not reduced in primary tumors without
metastases, whereas TBR2 was significantly reduced in primary
tumors with metastatic disease and in metastatic lesions. TBR3 was
reduced in all tumors (black bars).
[0081] The investigators have subsequently completed real-time PCR
analysis of TBR1, TBR2, and TBR3 expression in 16 primary tumors
without metastases (plus paired normal epithelium) and nine samples
of primary tumors with metastatic disease, paired metastatic
lesions, and paired normal tissue. The data were consistent with
those shown for the samples analyzed in FIG. 1A. TBR3 expression
was significantly reduced in all tumors; whereas TBR2 expression
was reduced in only 1/16 primary tumors without metastatic lesions,
but was reduced in primary tumors with metastatic lesions (8/9).
These data show that loss of TBR3 is an early event in renal cell
carcinoma, strongly suggesting that TBR3 plays a critical role in
renal cell carcinoma carcinogenesis.
[0082] The loss of TBR3 mRNA expression was also correlated with
TNM scores (T, histological score; N, lymph node number; M, number
of organ metastases) from patient samples (data not shown). TBR3
mRNA expression was suppressed in the earliest stage, stage I, and
was found to be suppressed in all tumor stages (1-IV). In addition,
loss of TBR2 in the primary tumor is significantly associated with
acquisition of the metastatic phenotype and clinically manifests as
metastatic progression.
EXAMPLE 7
[0083] Attenuation of TGF-b-Mediated Signal Transduction in Human
Renal Cell Carcinoma
[0084] Decreased type III TGF-b receptor (TBR3) mRNA expression in
all tumors was associated with failure to detect TBR3 protein by
immunohistochemistry (FIG. 12). Type II TGF-b receptor (TBR2)
protein was detected in localized tumor (primary, no mets), but was
not detectable in primary tumors with metastatic disease or in
corresponding metastatic lesions. Type I TGF-b receptor (TBR1)
protein was detected in normal tissue and in all tumor samples.
[0085] The investigators hypothesized that these losses seen in
TGF-b receptor expression would manifest as an attenuation of
TGF-b-mediated signal transduction, and would significantly alter
the expression of TGF-b-regulated genes. From the gene array data
disclosed above, 13 known TGF-b/Smad-regulated genes were
down-regulated in renal cell carcinoma (Table 7). Using mRNA from
35 patient-matched samples, the investigators verified loss of
expression of three of these genes by comparing matched normal and
tumor tissue. Real-time PCR was used to measure the expression of
Collagen IV type 6, fibulin-5, and connective-tissue growth factor
(CTGF). Collagen IV type 6 (gray bars) is an extracellular matrix
protein that plays a critical role in the regulation of membrane
integrity and cell signaling. Fibulin-5 is a recently discovered
TGF-b-regulated gene, which has tumor suppressor activity.
Fibulin-5 is an extracellular matrix protein that is believed to
signal through interaction with integrins. CTGF is a secreted
protein involved in angiogenesis, skeletogenesis, and wound
healing. CTGF enhances TGF-b1 binding to TBR2, and CTGF and TGF-b
collaborate to regulate the expression of extracellular matrix
proteins during renal fibrosis. As summarized graphically in FIG.
13, all the evaluated TGF-b-regulated genes were down-regulated in
early tumor stages, suggesting that renal cell carcinoma undergoes
loss of TGF-b responsiveness at an early stage. These data indicate
that this loss of TGF-b sensitivity is due, primarily, to loss of
type III TGF-b receptor (TBR3) in early tumor development and
further loss of sensitivity in metastatic disease is mediated
through subsequent loss of type II TGF-b receptor (TBR2).

EXAMPLE 8
[0087] TGF-b Receptor Expression in Renal Cell Carcinoma Cell
Lines
[0088] Human renal cell carcinoma cell lines were identified that
recapitulate the clinical observations of TGF-b receptor biology
described above. UMRC6 cells were derived from a clinically
localized human renal cell carcinoma (Grossman et al., 1985). As
shown in FIG. 14A, UMRC6 cells express type II TGF-b receptor
(TBR2) mRNA, but not type III TGF-b receptor (TBR3).
Immunohistochemical analysis (FIG. 14B) confirms the presence of
TBR2 protein and the absence of TBR3 expression. UMRC3 cells were
derived from the primary tumor of a patient with metastatic renal
cell carcinoma. This highly aggressive cell line lacks detectable
TBR2 and TBR3 mRNA (FIG. 14A) and protein (FIG. 14B).
[0089] In addition to these relevant laboratory models, normal
renal epithelial (NRE) tissue was harvested from nephrectomy
specimens and established as primary cultures (Trifillis, 1999). As
shown in FIGS. 14A and 14B, these primary cultures of NRE expressed
TBR3, TBR2, and TBR1 mRNA and protein in vitro. NRE cells can be
grown in culture for 10 passages and were easily isolated and
characterized. NRE cells were characterized for cytokeratin
expression and tubule-specific gene expression, for example,
megalin (data not shown). Thus, there are relevant cell models in
which TBR2 and TBR3 expression can be manipulated to examine the
impact of TGF-b receptor biology on the carcinogenesis and
progression of human renal cell carcinoma in vitro.
EXAMPLE 9
[0090] TGF-b Activity in Renal Cell Carcinoma Cell Lines
[0091] It is well known that TGF-b1 inhibits cell proliferation in
epithelial cells. The present example demonstrates the effects of
TGF-b on renal tumor cell proliferation.
[0092] DNA content of cells was used as a measure of cell
proliferation. Cells were plated at 20,000 cells/well in 12-well
plates. Cells were grown in 10% FBS:DMEM:penicillin:streptomycin.
The following day, media were exchanged with appropriate treatment
added to the media. On day 3 of treatment, cells were analyzed for
DNA content using Hoechst reagent. DNA standard was used to
correlate DNA content per well.
[0093] As shown in FIG. 15A (squares), TGF-b1 inhibited the
proliferation of normal renal epithelial cells in culture. URMC3
cells expressed neither type II or type III TGF-b receptors and,
not surprisingly, were resistant to the inhibitory effects of TGF-b
on cell proliferation (triangles, FIG. 15A). UMRC6 cells expressed
type II but not type III TGF-b receptors, and were partially
resistant to TGF-b1 (circles, FIG. 15A).
[0094] TGF-b transcriptional activity was also measured in the
above cell models using transient transfection of the 3TP/lux
reporter, which contains an AP-1/Smad3 response element from the
PAI-1 promoter. This luciferase reporter construct demonstrates
increased transcriptional activity in response to exogenous
TGF-b-mediated signal transduction. 3TP/lux was transiently
transfected along with SV/renilla luciferase (Promega) into cells
using fugene (Roche) as the transfection agent. Cells were treated
with or without TGF-b1 24 h after transfection and luciferase
activity (Promega Luciferase Assay system and Lumat luminometer)
was determined 24 h after TGF-b treatment. Firefly luciferase
activity was normalized using the ratio of firefly
luciferase/renilla luciferase. As shown in FIG. 15B, normal renal
epithelial cells were highly responsive to 2 ng/ml (80 pM) of
TGF-b1. UMRC6 cells demonstrated significantly less luciferase
activity in response to TGF-b1, and UMRC3 cells were entirely
unresponsive.
EXAMPLE 10
[0095] Recapitulation of TGF-b Signaling Through Reintroduction of
TGF-b Receptor Expression into Renal Cell Carcinoma
[0096] To test whether reintroduction of TGF-b receptor expression
would result in re-establishment of TGF-b signal transduction and
reacquisition of TGF-b cellular sensitivity, UMRC3 cells were
engineered to express stably either type II TGF-b receptor (+TBR2)
alone or type II plus type III TGF-b receptor (+TBR2+TBR3).
[0097] Plasmid construction and transfection were described as
follows. The complete coding sequences for human type II TGF-b
receptor (TBR2) was cloned into the EcoRI/XbaI site of pcDNA3/FLAG.
The expression vector was stably transfected into UMRC3 cells using
fugene as DNA carrier and genticin as selection antibiotic (Sigma,
1 mg/ml). Ten clones (UMRC3/TBR2) were selected and verified for
TBR 2 mRNA and protein expression such as Western analysis using
the FLAG antibody (data not shown). From these cell clones, one was
to be selected that had equivalent protein expression of TBR2 to
that of normal renal epithelial (NRE) and UMRC6 cells.
[0098] The type III TGF-b receptor (TBR3) coding sequence was PCR
amplified from a plasmid expressing wild-type TBR3 in pSV7d (a gift
from Dr C--H Heldin). TBR3 was then cloned into the EcoRI site of
pcDNA4/TO/myc-His.RTM. (InVitrogen) in the sense and antisense
(negative control) orientation. The orientation and sequence of
TBR3 was verified. The antisense TBR3 (As TBR3) vector was used as
a control. TBR3/pcDNA4/TO/myc-His and As TBR3/pcDNA4/TO/myc-His
vectors were stably transfected into UMRC3/TBR2 cells. A clone was
selected that demonstrated an equivalent expression of TBR3 mRNA to
that of normal renal epithelial cells. As a control for UMRC3+TBR2
and UMRC3+TBR2+TBR3, wild-type UMRC3 were stably transfected with
both pcDNA/FLAG and pcDNA4/TO/myc-His vectors.
[0099] As shown in FIG. 16A, stable transfection of type II TGF-b
receptor (TBR2) alone or type II plus type III TGF-b receptor
(TBR2+TBR3) resulted in detectable levels of mRNA for each receptor
on RT-PCR analysis. On examining the in vitro growth kinetics of
these re-engineered cells, it was noted that reintroduction of TBR2
resulted in a twofold reduction in cell proliferation and
reintroduction of both TBR2 and TBR3 resulted in a fourfold
reduction in cell proliferation with the addition of exogenous
TGF-b 1.
[0100] The investigators then examined TGF-b-mediated
transcriptional activity as a consequence of TGF-b receptor
re-expression. As shown in FIG. 16B, reintroduction of TBR2
partially restored transcriptional responsiveness, as evidenced by
a 5.6-fold increase in 3TP/lux activity after addition of TGF-b1.
Reintroduction of both TBR2 and TBR3 into UMRC3 cells resulted in
17.5-fold increase in 3TP/lux activity after addition of
TGF-b1.
[0101] To demonstrate reestablishment of TGF-b-regulated gene
expression, collagen IV type 6 mRNA expression was examined by
real-time PCR in these re-engineered cell lines in the presence of
TGF-b1. As shown in FIG. 16C, reexpression of TBR2 in UMRC3 cells
results in a sevenfold increase in collagen IV type 6 mRNA levels
over that of UMRC3 controls, while reintroduction of both TBR2 and
TBR3 enhanced collagen IV type 6 mRNA expression 11-fold. These
data are consistent with a number of published reports that
indicate expression of TBR3 is essential for full TGF-b
responsiveness.
[0102] UMRC3 cells have been shown to be tumorigenic in athymic
nude mice (Grossman et al., 1985). Anchorage independent growth in
soft agar is a well-established in vitro correlate of in vivo
tumorigenicity. Colonies formation in soft agar was determined as
follows. UMRC3 (pcDNA/FLAG and pcDNA4/T0/myc-His empty vectors),
UMRC3+TBR2, or UMRC3+TBR2+TBR3 cells were plated at 1000 cells/60
mm dish in an agarose/FBS/media sandwich in the presence of 2 ng/ml
TGF-b. No selection antibodies were added to the agarose media
mixture. The cells were incubated for 45 days to insure that no
colony formation would occur. Cells were then stained with 0.005%
Crystal Violet, photographed, and assessed for number and size of
colonies.
[0103] As shown in FIG. 16D, UMRC3 cells demonstrated anchorage
independent growth in soft agar. Reintroduction of TBR2 into UMRC3
cells significantly decreased the number and size of colonies that
formed in soft agar. Reintroduction of both TBR2 and TBR3
completely abrogated the ability of UMRC3 cells to form colonies in
soft agar, even after 45 days in culture. These data demonstrate
that reintroduction of TBR2 resensitizes UMRC3 cells to the effects
of exogenous TGF-b through reacquisition of TGF-b signal
transduction. More interestingly, however, reintroduction of TBR3
in the presence of TBR2 into UMRC3 cells significantly enhanced
TGF-b-regulated gene transcription, growth inhibition, and loss of
anchorage-independent growth over that seen with reintroduction of
TBR2 alone. These data clearly show that renal cell carcinoma cells
are TGF-b resistant. Loss of TBR3 expression occurs early and
appears to be associated with a relatively less aggressive state
that is partially TGF-b responsive. Loss of TBR2 results in frank
TGF-b resistance and is associated with acquisition of a more
aggressive phenotype.
[0104] FIGS. 17-18 demonstrate that re-expression of type II or
type III TGF-b receptor in the highly metastatic human renal cell
carcinoma cell line UMRC3 inhibited cell proliferation in cell
culture and tumor growth in a nude mouse model. The TGF-b receptors
were either re-expressed in a stable vector system or as an
adenoviral vector. For clinical purposes, it would be envisioned to
treat patients with an adenovirus expressing one or both of the
TGF-b receptors to block tumor growth or cause tumor
regression.
EXAMPLE 11
[0105] Stepwise Sequential Loss of Type III And Type II TGF-b
Receptor Expression in Renal Cell Carcinoma
[0106] With genomic profiling in human renal cell carcinoma, the
data presented above demonstrated a stepwise sequential loss of
type III and type II TGF-b receptor expression in association with
renal cell carcinogenesis and progression. These findings were
confirmed by both immunohistochemistry and real-time PCR in
patient-matched tissue samples. This clinical observation was
brought to the laboratory to identify relevant in vitro models.
Using these models, it was demonstrated that loss of type III TGF-b
receptor expression resulted in incremental desensitization to
TGF-b and attenuation of TGF-b signaling. Subsequent loss of type
II TGF-b receptor resulted in complete loss of TGF-b sensitivity.
With in vitro modulation of TGF-b receptor expression, it was
demonstrated that reconstitution of the TGF-b signaling pathway
resulted in significant growth inhibition and loss of the
aggressive phenotype.
[0107] These experiments are unique in that clinically relevant
observations, which are derived from the evaluation of gene
expression in normal renal cortical tissue, localized renal cell
carcinoma and metastatic renal cell carcinoma, were brought to the
laboratory for validation and experimental manipulation in relevant
in vitro models. Other investigators have examined human renal cell
carcinoma cell lines and identified alterations in the expression
of TGF-b signaling pathway intermediaries, but those observations
have not been validated in the clinical biology of renal cell
carcinoma. To the investigators' knowledge, few studies have
methodically examined the expression of all three TGF-b receptors
in patient samples at the protein and mRNA level in an effort to
correlate TGF-b receptor expression to disease-specific states of
renal cell carcinoma (i.e. localized versus metastatic tumor). A
major strength of the present study is that the investigators
recognized distinct disease states in renal cell carcinoma,
associated them with specific alterations in the TGF-b signaling
pathway, and then validated and manipulated the clinical
observations in the laboratory.
[0108] Although the mechanisms are not well understood, it is clear
that TGF-b regulates a large number of diverse biological
functions, including cell proliferation, differentiation, cell
adhesion, apoptosis, extracellular matrix production, immune
regulation, neuroprotection, and early embryonic development. In
epithelial cells, the effect of TGF-b is generally to inhibit
proliferation, promote cellular differentiation, and regulate
interactions with the extracellular matrix. As a direct
consequence, aberrations in TGF-b signaling can have a dramatic
impact on cellular processes that are critically associated with
neoplastic and malignant transformation. Given the well-documented
observation that the end result of TGF-b signaling is largely
growth inhibitory, it makes intuitive sense that cancer cell would
develop mechanisms to escape TGF-b sensitivity. To date, these
mechanisms have not been elucidated in human renal cell
carcinoma.
[0109] Based on the data presented above, the investigators
hypothesize that this escape from the growth-inhibitory effects of
TGF-b is mediated through the stepwise sequential loss of type III
and type II TGF-b receptor expression. To the investigators'
knowledge, no one has linked sequential loss of these two types of
receptors to carcinogenesis and metastatic progression in oncology.
This is the first time that stepwise loss of a single transduction
pathway has been associated with important biologic sequelae in a
human cancer.
[0110] Results presented in the present invention demonstrate that
loss of type III TGF-b receptor expression is an early event in
renal cell carcinoma biology and that this loss has important
sequelae with regard to renal cell carcinoma carcinogenesis and
progression. All clinical samples of localized renal cell carcinoma
demonstrated loss of type III TGF-b receptor, but had normal
expression of type I and type II TGF-b receptors. Replication of
this clinical observation in in vitro models demonstrated
significant loss of TGF-b sensitivity, manifest as a significant
reduction in the growth inhibitory effects of TGF-b1 and
significantly reduced TGF-b-mediated transcription. Interestingly,
cell lines derived from localized RCC retained type II TGF-b
receptor expression and therefore, still demonstrated sensitivity,
albeit reduced, to TGF-b. Only with metastatic progression and loss
of type II TGF-b receptor expression does the cell become
completely resistant to the effects of TGF-b. The investigators
hypothesize that this retained, but attenuated, TGF-b signaling
seen in local tumors must convey some as yet unrecognized biologic
benefit for local tumors that is no longer required, and therefore
discarded, with metastatic progression. In fact, this loss of type
II TGF-b receptor expression may be an absolute integral component
in the cascade of intracellular events that lead to the development
of metastatic potential. In keeping with this hypothesis, it has
been shown that loss of type II TGF-b receptor expression was one
of 40 integral alterations of gene expression to predict for poor
prognosis of patients diagnosed with renal cell carcinoma.
[0111] In summary, the above results demonstrate a clear link
between loss of type III TGF-b receptor expression to a human
disease state. Reduced type III TGF-b receptor (TBR3) expression
has been reported in human breast tumor cell lines, suggesting that
loss of TBR3 expression may be a more ubiquitous phenomena in
carcinogenesis, rather than an isolated finding in human RCC
biology. The fact that the investigators found down-regulation of
TBR3 in every renal cell carcinoma specimen studied to date (35
patients) and that re-expression of TBR3 (in the presence of
re-expressed TBR2) completely abolish growth on soft agar suggests
an important role for TBR3 in normal renal epithelial homeostasis
that must be abrogated for renal cell carcinogenesis and
progression to occur. Little attention has been given to TBR3 in
normal cell biology or the changes in expression that occur with
carcinogenesis and progression. Observations from the present
invention would suggest that TBR3 plays an important functional
role in signaling and that loss of expression is an important event
in the acquisition of the tumorigenic and metastatic phenotype.
