BACKGROUND OF THE INVENTION

Technical Field

[0003] The present invention relates to compositions suitable for topical administration, the compositions comprising pharmacologically active polypeptides that are encapsulated in a liposome and/or nano-liposome. The invention also relates to methods of manufacturing the liposome and/or nano-liposome formulations. The invention further relates to methods for improving and/or treating skin conditions, enhancing wound healing, and for inhibiting subcutaneous fat formation.

Related Art

[0004] Heat Shock Protein 90a, abbreviated as HSP90a hereafter, is a dimer composed of two monomers containing phosphate groups, and having a molecular weight of 90 KD. The two monomers tend to become easily oligomerized under some conditions, e.g., when present in aqueous solution. Most Heat Shock Proteins have been known to function intracellularly. Other reports indicate that some Heat Shock Proteins work outside the cell, suggesting alternative physiological roles. The role of HSP90a in immune-regulation has been suggested.sup.10,12. However, no systemic studies have been carried out with HSP90a, nor has it been described as having any activity for affecting skin conditions, such as atopic dermatitis or skin aging, or as affecting subcutaneous fat formation or accumulation. The relatively large size of the HSP90a fragment has precluded the use of this molecule in topical preparations, as it is unable to penetrate to the skin dermis layer.sup.6.

[0005] Atopic dermatitis (AD) is a chronic dermal disorder caused by defects in stratum corneum, which is generally considered idiopathic.sup.9. It affects children and adults as well. Its epidemiology has been known to associate with hereditary.sup.4 or environmental causes.sup.7, and immunological factors.sup.9.

[0006] There is no known cure for AD thus far, although treatments may reduce the severity and frequency of flares. Commonly used compositions for treating atopic dermatitis include small molecule based compounds with properties of anti-histamine, steroids or immune suppression. Alternatively systemic immune suppressing agents may be tried such as cyclosporine, methotrexate, interferon gamma-1b, mycophenolate mofetil and azathioprine.sup.4. However since these small-molecules based compounds accompany such serious adverse effects as deterioration of immune function upon long term use, new materials to overcome such barriers are needed in the treatment of these and other conditions.

[0007] Unlike small molecule based medicine, there are significant advantages in using a polypeptide as active ingredients for the treatment of dermal disorders and/or preparing skin cosmetic products. For example, polypeptides are generally more compatible with interactions with the immune system and cells, and generally decomposed in a pro-physiological manner within the body, hence generating fewer side effects compared to small molecule (chemical) containing preparations, especially during long term use. Furthermore, as relates to uses in cosmeceutical preparations, small molecule containing cosmetic products generally produce only short term cosmetic effects, while polypeptide containing cosmeceutical preparations have been described as providing longer term improvement of overall skin condition, and even skin rejuvenation.sup.3. However, the overall size and bulkiness of many potentially useful polypeptides prevents the penetration of these ingredients into skin tissues.

[0008] Traditionally, macromolecules having a molecular weight of 500 Daltons or more are considered too large to pass through the skin epidermis due to the skin keratin barrier.sup.6. Even when used with chemical penetration enhancers, macromolecules having a molecular weight of more than 2000 Daltons are considered practically implausible for topical use, as they are unable to penetrate the skin epidermis. Therefore, peptides developed as pharmaceutical/cosmetic ingredients have been limited to those having a much smaller size, such as a size of less than 10 amino acids (roughly about 1100 Daltons MW), so as to optimize the delivery of the active ingredient to the skin dermis. Thus, many potentially useful polypeptides having a size of 10 amino acids or greater have not been utilized in topical preparations. Delivery of an active ingredient, such as a polypeptide, to the skin dermis layer, is necessary to provide the most pharmaceutically meaningful outcomes with functional pharmaceutical/cosmetic preparations.

[0009] Liposome based delivery of human growth hormone (hGH), having a MW of 22,124 Daltons (191 amino acid size), has been reported.sup.1-3. However, challenges associated with effective topical delivery of other pharmacologically different peptides/proteins, such as heat shock protein Hsp90a, remain.

[0010] A 115 amino acid fragment of Heat Shock Protein, termed HPf, is encoded by an amino acid sequence spanning between the linker and the middle domain of the native endogenous HSP sequence (FIG. 1). This fragment has been reported to ameliorate skin necrosis caused by diabetic ulcer..sup.8 Improvements in delivery products are, however, lacking for facilitating fuller use and formulation of these and related polypeptides.

[0011] Subcutaneous fat is the layer of subcutaneous tissue that is most widely distributed and is mainly composed of adipocytes. The number of adipocytes varies among different areas of the body, while their size varies according to the body's nutritional state (Subcutaneous Tissue, Medical Subject Headings (MeSH), NLM Retrieved 5 Jun. 2013). Some reports suggest that reducing the size of fat cells could improve fat cell sensitivity to insulin.sup.5. Numerous small molecule based oral delivery medicines have been developed and marketed for suppressing the accumulation of fat. Oral administration of these types of preparations, however, is associated with adverse side effects. A topical preparation would be more effective in such applications, and would offer the advantage of targeting problem fat deposit areas on the body, among other advantages.

[0012] One of the many barriers in the use of polypeptides in topical preparations remains the size and bulkiness of these polypeptide and protein molecules, which, because of the structure of skin tissues, do not penetrate the skin sufficiently to provide beneficial pharmacological and physiological effects in the body. Conventional approaches to this problem have been the use of mesotherapeutic devices, such as micro needles, electroporation devices, laser treatments, and infrared irradiation. For a variety of reasons, these approaches have not provided a sufficiently effective and convenient approach for topical administration of peptide-containing preparations. Problems associated with sufficient shelf-life and product biological stability also limit the use of polypeptide/peptide/protein based topical and other preparations.

[0013] A need continues to exist in the medical arts for improved topical preparations with preserved bioactivity and enhanced shelf-life of identified polypeptide/protein-based molecules. In addition, a need continues to exist for achieving effective delivery of these and other potent polypeptide/protein agents deep into skin tissues to achieve maximal physiological benefit to the patient. The present invention provides a solution to these and other technical problems in the medical arts for the use of polypeptide and/or protein-based molecules in topical and other delivery formulation applications and treatment methods.

SUMMARY OF THE INVENTION

[0014] The present invention provides, for the first time, liposomal and nano-liposomal encapsulated Heat Shock Protein (HSP) preparations, as well as preparations that include smaller polypeptide fragments of HSP, namely HPf (115 aa), as well as novel polypeptides HPf.DELTA.C1 (101 aa), and HPf.DELTA.C2 (87 aa). The liposomal preparations are further demonstrated to possess a number of novel and advantageous physiological effects when delivered topically at the skin surface, including the enhancement of wound healing, the inhibition of fat cell differentiation, the improvement of skin conditions (including atopic dermatitis, wrinkle, skin elasticity and dark spots, and promoting overall skin rejuvenation) and effective delivery to skin hair follicles.

[0015] The polypeptide compositions and preparations may further be provided as nano-liposomal encapsulated preparations. These preparations are demonstrated to possess long term storage stability and retained bioactivity in solution. The preparations may be provided in a delivery form suitable for topical, mesotherapeutic or systemic administration.

[0016] Surprisingly, the present invention has accomplished the effective delivery of HPf, a 115 amino acid fragment of HSP90a, to the stratum corneum of both intact skin and wounded skin, using a topical formulation of the polypeptide in a liposome-based delivery preparation.

[0017] According to some aspects of the invention, a liposomal (particularly, a nano-liposomal) encapsulated polypeptide composition is provided comprising a Heat Shock Protein, and HPf polypeptide or fragment thereof, as an active ingredient.

This activity, in turn, inhibits the progression and severity of atopic eczema and/or atopic dermatitis. This feature provides yet another objective of the present invention.

[0020] In another embodiment of the present invention, a composition is provided for use in a medicament for suppressing subcutaneous fat accumulation and fat cell differentiation.

In some embodiments, the polypeptide is defined by a 115 aa sequence (termed HPf) (SEQ ID. No. 1), a 101 aa sequence (HPf.DELTA.C1) (SEQ ID. NO. 20), an 87 aa sequence (HPf.DELTA.C2) (SEQ ID. NO. 21), or an HSP90a aa sequence (SEQ. ID NO. 2), the polypeptide being encapsulated in a nano-liposome.

[0023] Yet another aspect of the invention provides for transformed cell lines useful in the production and/or manufacture of recombinant HSP90a and HPf polypeptides (HSP90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2). By way of example, cell lines that may be used in the preparation of these transformed cell lines include a TOP 10 cell line, a BL21(D3)pLys cell line, RosettaBlue(DE3) cell line, and RZ4500 cell line. Expression vectors that include a sequence encoding a fusion protein comprising the HSP90a HPf, and/or HPf polypeptide fragments, with a fusion partner protein/peptide, are also disclosed, and are useful in the large-scale and economical production of these useful therapeutic polypeptides. The fusion protein constructs are also defined as part of the present invention.

[0024] Another aspect of the invention provides for a method of manufacturing recombinant HSP90a and HPf polypeptides, including the HSP90a, HPf, HPf.DELTA.C1, and HPf.DELTA.C2 polypeptides.

[0025] Yet another aspect of the invention provides a topical liposomal polypeptide formulation containing HSP90a, an HPf polypeptide (HSP90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2), or a combination thereof, for use in the treatment of a skin condition, wherein the skin condition is atopic dermatitis, wrinkles, dark spots, skin elasticity or skin aging, wherein said composition comprises a concentration of about 100 ng/ml to about 1 mg/ml of the HPf polypeptide or HPf polypeptide fragment.

[0027] The invention also provides for a use of a HSP90a, an HPf polypeptide or fragment thereof (HPf.DELTA.C1, HPf.DELTA.C2), or a combination thereof, in the manufacture of a preparation for the treatment of a skin condition, wherein the skin condition is atopic dermatitis, wrinkles, dark spots, skin elasticity or skin aging.

[0028] The invention also provides for a use of a HSP90a, an HPf polypeptide or fragment thereof (HPf.DELTA.C1, HPf.DELTA.C2), or a combination thereof in the manufacture of a preparation for the treatment of obesity, cellulite, varicose veins of lower extremities with ulcer, lower body extremity edema, varicose veins, skin discoloration, venous eczema, scleroderma, inflammatory thrombus, skin ulcer, or chronic pain.

DETAILED DESCRIPTION OF THE INVENTION

[0047] The present inventors have performed intensive research in the identification and manufacture of topical liposomal encapsulated HPf polypeptide and HPf polypeptide fragment compositions having potent pharmacological activity in vivo. The topical preparations include a polypeptide encoded by the amino acid at SEQ ID. No. 1, or a fragment thereof, as an active ingredient. The pharmacological activity of the compositions include improvement of skin conditions, including atopic dermatitis, wrinkles, dark spots, improving skin elasticity and skin rejuvenation, as well as enhancing wound healing. In addition, the compositions are also demonstrated to inhibit subcutaneous fat cell differentiation and to suppress the accumulation of subcutaneous fat.

[0048] The term `human heat shock protein 90a fragment` or `HSP90a fragment` represents the HSP90a of which partial sequences were removed by biochemical or DNA recombinant techniques. A polypeptide fragment of HSP90a is described as HPf herein. HPf is a 115 amino acid fragment of endogenous HSP90a, and is encoded by the sequence spanning from amino acid (aa) 236 to aa 350, including the "Linker" region (see FIG. 1). HPf.DELTA.C1 is the 101 amino acid fragment of the endogenous HSP90a encoded by the sequence spanning from aa 236 to aa 336; and HPf.DELTA.C2 is the 87 amino acid fragment of the endogenous HSP90a encoded by the sequence spanning from aa236 to aa 322 (see FIG. 1) of the full amino acid sequence of HSP90a (SEQ ID. NO. 2).

[0049] As HPf protein showed a very high propensity of forming aggregates as characterized by ELS and GFC analyses of FIG. 9, its aa sequence and 3D structure were examined for the reasons of HPf aggregation, and the present inventors sought to devise ways to overcome this aggregation problem. The present inventors suspected a hydrophobic stretch of aa sequence in HPf might be the reason for this aggregation. Therefore, two other constructs were designed, HPf.DELTA.C1 and HPf.DELTA.C2, that eliminated the hydrophobic stretch of HPf, and presented novel polypeptides. The resultant HPf.DELTA.C1 and HPf.DELTA.C2 showed much better aggregation profile, and hence gave HPf.DELTA.C1 or HPf.DELTA.C2 separation and purification advantages over HPf. HPf.DELTA.C1 construct gave a soluble HPf.DELTA.C1 protein form while HPf.DELTA.C2 gave an inclusion body form when each over-expression was attempted. To increase the separation yield and facilitate the purification efficiency, the smallest fragment HPf.DELTA.C2 was chosen for further studies. The HPf.DELTA.C2 polypeptide was surprisingly found to be at least as active as HPf, and in some parameters, to be even more active than HPf.

[0050] The biochemical/biological properties of the HPf and HPf.DELTA.C2 can be determined based on the following three factors: 1) Over 90% of the amino acid sequence identity with HPf or HPf.DELTA.C2, 2) Binding of each fragment to the receptor or other binding proteins of the endogenous HSP90a, and 3) the biological activity of HPf or HPf.DELTA.C2.

[0051] According to some embodiments, a composition according to the present invention is a phospholipid or liposome composition, and preferably a liposome or nano-liposomal composition. In some embodiments, the HPf (encoded by SEQ ID. NO. 1) is encapsulated in liposomes or nano-liposomes, and applied to the skin. According to some embodiments, the inventive composition is a nano-liposomal composition formulated for topical administration.

[0052] As used herein, the term "nano-liposome" refers to a liposome having the form of conventional liposome and a mean particle diameter of 20-1000 nm. According to some embodiments, the mean particle diameter of the nano-liposome is 50-500 nm, more preferably 50-350 nm, and most preferably 100-250 nm.

[0053] As used herein, the term "liposome" refers to a spherical phospholipid vesicle of colloidal particles which are associated with themselves, and liposomes composed of amphiphilic molecules, each having a water soluble head (hydrophilic group) and a water insoluble tail (hydrophobic group), and show a structure aligned by spontaneous binding caused by the interaction there between. The liposome is classified, according to the size and lamellarity thereof, into SUV (small unilamellar vesicle), LUV (large unilamellar vesicle) and MLV (multi lamellar vesicle). The liposomes showing various lamellarities as described above have a double membrane structure similar to the cell membrane.

[0054] The nano-liposome and liposome of the present invention can be prepared using phospholipid, polyol, a surfactant, fatty acid, salt and/or water.

[0055] The phospholipid which is a component used in the preparation of the liposome and nano-liposome, is used as an amphipathic lipid. By way of example, such amphipathic lipids include natural phospholipids (e.g., egg yolk lecithin, soybean lecithin, and sphingomyelin) and synthetic phospholipids (e.g., dipalmitoylphosphatidyl-choline or hydrogenated lecithin), the lecithin being preferred. More preferably, the lecithin is a naturally derived unsaturated or saturated lecithin extracted from soybean or egg yolk.

[0056] Polyols which can be used in the preparation of the inventive nano-liposome are not specifically limited, and may include propylene glycol, dipropylene glycol, 1,3-butylene glycol, glycerin, methylpropanediol, isoprene glycol, pentylene glycol, erythritol, xylitol and sorbitol.

[0057] The surfactant which can be used in the preparation of the inventive nano-liposome may be any surfactant known in the art, and examples thereof include anionic surfactants (e.g., alkyl acyl glutamate, alkyl phosphate, alkyl lactate, dialkyl phosphate and trialkyl phosphate), cationic surfactants, amphoteric surfactants and nonionic surfactants (e.g., alkoxylated alkylether, alkoxylated alkylester, alkylpolyglycoside, polyglycerylester and sugar ester).

[0058] The fatty acids which can be used in the preparation of the inventive nano-liposome are higher fatty acids, and preferably saturated or unsaturated fatty acid having a CI 2-22 alkyl chain, and examples thereof include lauric acid, myristic acid, palmitic acid, stearic acid, oleic acid and linoleic acid.

[0059] Water which is used in the preparation of the inventive nano-liposome is generally deionized distilled water.

[0060] According to some embodiments, the inventive nano-liposome is prepared only with phospholipid, salt and water, as described in detail in the Examples below.

[0061] According to some embodiments, the HPf-containing nano-liposome is prepared through a process comprising the steps of: (a) dissolving a phospholipid capable of forming liposome (preferably, yellow yolk lecithin or soybean lecithin) in a buffered aqueous solution of salt containing HPf; and (b) passing the aqueous solution containing HPf and phospholipid through a high-pressure homogenizer while gradually increasing the content of the phospholipid and the pressure of the high-pressure homogenizer as the number of the passages increases, thus preparing a HPf-containing nano-liposome.

[0062] The aqueous solution containing HPf is preferably a buffer solution having a pH of 6-8, and more preferably about 7, for example, sodium phosphate buffer solution. If the sodium phosphate buffer solution is used, the concentration thereof will preferably be 5-100 mM, more preferably 5-60 mM, even more preferably 10-30 mM, and most preferably about 20 mM.

[0063] The mixture of the phospholipid and the HPf-containing aqueous solution is passed through a high-pressure homogenizer several times, in which the amount of the phospholipid and the pressure of the homogenizer are gradually increased as the number of the passages increases. According to a preferred embodiment of the present invention, the pressure of the homogenizer is increased gradually to 0-1000 bar, and preferably 0-800 bar. The pressure can be increased by 50 bar or 100 bar in each cycle, and preferably 100 bar. According to a preferred embodiment of the present invention, the amount of the phospholipid is gradually increased to 5-40 w/v (%) in each cycle, and more preferably 5-30 w/v (%). Through the high-pressure homogenization process including these gradual increases in phospholipid content and pressure, an HPf-containing nano-liposome is prepared and a liquid HPf-containing nano-liposome is preferably prepared.

[0064] The present invention is shown herein to be effective for treating atopic dermatitis. While not wishing to be limited to any particular theory or mechanism of action, it is contemplated that this effect may be the result of suppressing the immune function around the affected areas while simultaneously healing the wounds, whereas anti-histamine or steroid containing compositions traditionally used for atopic dermatitis work only by suppressing the immune functions without a wound healing activity.

EXAMPLES

[0076] The following specific examples are intended for illustrating the invention and should not be construed as limiting the scope of the invention as defined by appended claims.

Example 1. Obtaining the Fragment of Hsp90a (Hpf)

[0077] 1-1) Amplification of the HSP90a fragment (HPf1 cDNA

[0078] The 115 amino acids polypeptide (SEQ ID. NO. 1) used in the present invention is a fragment of HSP90a (UniProt id: P07900), the sequence spanning from amino acid (aa) no. 236 to aa no. 350 of the endogenous protein. This fragment is referred to as a fragment HPf. In order to produce the HPf in a large scale, the HPf gene was cloned and expressed in E. coli.

[0079] More specifically, to clone the gene from the human cDNA library, HEK (Human Embryonic kidney) 293 cell line (CRL-1537, ATCC, USA) was incubated in 6 well plates for 3 days. After the removal of the culture media TRizol solution (Invitrogen, USA) 1 ml was added to dissolve the cells, which was then mixed with 200 .mu.l chloroform by strong vortexing for 10 seconds. The mixture was centrifuged at 12,000.times.g (Centrifuge 5418, Eppendorf, USA) for 15 minutes. After the supernatant was collected and transferred to a new E-tube 0.5 ml isopropyl was added and centrifuged at 12,000.times.g for 10 minutes to precipitate the total RNA. The total RNA was washed with 70% ethanol once then dissolved in water free of RNAse and DNAse. Such purified RNA was used to construct the cDNA library. The cDNA was synthesized using Omniscript Reverse Transcription kit (Qiagen, U.S.A.) following the instruction provided in the manufacturer's manual. First, the total RNA 1 .mu.g, IX RT buffer, dNTP mix, oligo-dT primers, RNAse inhibitors and Omniscript Reverse Transcriptase were mixed, then DNase, RNase free water was added to adjust the volume to 20 .mu.l, which then was incubated at 37.degree. C. for 60 minutes to obtain the cDNA library. Using the cDNA library as the template, genes to be cloned were prepared by amplifying by PCR. The PCR mixture contains IX PCR buffer, 6.4 .mu.l 2.5 mM dNTP mix, template (cDNA prepared above), 0.8 .mu.l 100 pmole primer stock, (SEQ ID. NO. 4 and 5) and 0.4 .mu.l proofreading Taq polymerase (TAKARA, Japan) in total volume of 100 .mu.l. The PCR was performed at 95.degree. C., 30 seconds for denaturing, 60.degree., 30 seconds for annealing, 72.degree., 45 seconds for amplification, repeating 35 cycles to amplify the HPf gene. Subsequently the product was analyzed using agarose gel electrophorosis to verify the amplification of HPf gene. The HPf nucleotide sequence is encoded by the SEQ ID. NO. 3, and the amino acid by sequence at SEQ ID. NO. 1.

[0080] 1-2) Preparation of the Recombinant HPf Protein

[0081] The HPf cDNA obtained from the Example procedure 1-1 above (cDNA of SEQ ID. NO. 3) prepared through amplification with two primers (SEQ ID. NO. 4 and SEQ ID. NO. 5) was cloned into pNKmut plasmid (Korean Patent 10-0985746) using restriction enzymes NdeI and KpnI (FIG. 2-1A).

[0082] To increase the stability and production of HPf, fusion proteins of HPf were expressed using TRX (Thioredoxin A, pET-32a, Novagen, USA), MBP (maltose binding protein, GeneScript, USA), or HGH (human growth hormone, DNA-sequence ID: NM_000515.3) as a fusion partner fused in front of HPf.

[0083] To facilitate purification of HPf from the fusion protein with TRX, a cleavage site for either hydroxylamine(Asn/Gly; N/G) or TEV (Tabacco Etch Virus) was inserted in between TRX and HPf in the fusion construct.

[0084] To prepare a fusion protein TRX(NGc)-HPf that is a chimeric construct of HPf coupled to a fusion partner TRX with an internal hydroxylamine cleavage site, TRX DNA portion TRX(NGc) (SEQ ID. NO. 18) was obtained by performing PCR using primers (SEQ ID. NO. 8 and SEQ ID. NO. 9) and pET-32a (0.1 .mu.g) as the template following Example 1-1 above. Similarly HPf DNA portion was obtained by performing PCR using primers (SEQ ID. NO. 5 and SEQ ID. NO. 11) following the procedure as in Example 1-1. To combine TRX(NGc) and HPf DNA's, primers (SEQ ID. NO. 5 and SEQ ID. NO. 8) were adopted to perform PCR using the 1:1 mixture of TRX(NGc) and HPf as the template. The subsequent PCR product was subcloned into Expression Vector pNKmut (Korean Patent 10-0985746) using DNA restriction enzymes NdeI and KpnI (FIG. 2-1B).

[0085] Likewise, to prepare a fusion protein TRX(TEVc)-HPf that is a chimeric construct of HPf coupled to a fusion partner TRX with an internal TEV cleavage site, TRX DNA portion TRX(TEVc) (SEQ ID. NO. 19) was obtained by performing PCR using primers (SEQ ID. NO. 8 and SEQ ID. NO. 10) and pET-32a (0.1 .mu.g) as the template following Example 1-1 above. Similarly HPf DNA portion was obtained by performing PCR using primers (SEQ ID. NO. 5 and SEQ ID. NO. 12) following the same procedure as in Example 1-1. BamHI restriction site was also created between TRX and HPf for later ease of cloning manipulations. To combine TRX(TEVc) and HPf DNA's, primers (SEQ ID. NO. 5 and SEQ ID. NO. 8) were used to perform PCR using the 1:1 mixture of TRX(TEVc) and HPf as the template. The subsequent PCR product was subcloned into Expression Vector pNKmut (Korean Patent 10-0985746) using DNA restriction enzymes NdeI and KpnI (FIG. 2-1C).

[0086] TRX(NGc)-HPf or TRX(TEVc)-HPf fusion protein thus produced in a transformed E. coli cells showed a much greater level of expression compared to HPf produced without a TRX fusion partner (FIGS. 3-1A and 3-1B).

[0087] HPf protein's c-terminal deletion mutant--HPf.DELTA.C1 and HPf.DELTA.C2 is constructed. HPf.DELTA.C1 is a fragment of HSP90a (part of HSP90a) consisting of 101 amino acids in total comprising from Glu236 to Glu336 of HSP90a protein (UniProt ID: P0790), which was eliminated 14 amino acids from HPf in the carboxyl-terminal (SEQ ID. NO. 20). Also, HPf.DELTA.C2 is a fragment of HSP90a composed of 87 amino acids in total comprising from Glu236 to Asp322 (of HSP90a), which has 28 carboxyl-terminal amino acids less of HPf, resulting in the smallest protein of the present invention (SEQ ID. NO. 21) (FIG. 1).

[0088] In order to express the HPf.DELTA.C1 recombinant protein, the HPf cDNA, acquired from the Example procedure 1-1, was used as the template and Seq. no. 4 and 6 as primers, via a PCR method described in Example 1-1. The HPf.DELTA.C1 gene with the sequence identical to seq. no. 22 was thus obtained and was further cloned into protein expression vector pNKmut (Korean Patent 10-0985746) using DNA restriction enzymes NdeI and KpnI. (FIG. 2-2A).

[0089] To clone TRX(TEVc)-Hpf.DELTA.C1 fusion protein composed of Thioredoxin A coupled with TEV protease recognition site, HPf.DELTA.C1 gene was obtained by running a PCR using HPf cDNA as a template and seq.no 6 and 12 as primers by following the same PCR method described in Example 1-1 above. TRX(TEVc)-HPf fusion protein-expression plasmid and HPf.DELTA.C1 gene produced by the PCR were digested by BamHI and KpnI DNA restriction enzymes, then HPf.DELTA.C1 was cloned into HPf gene-eliminated plasmid by substitution, yielding HGH(TEVc)-HPf.DELTA.C1 fusion protein-expression plasmid. (FIG. 2-2B).

[0090] In order to express HPf.DELTA.C2 recombinant protein, HPf cDNA acquired from Example 1-1 was used as the template, and primers for seq. no. 4 and 7 were used to acquire HPf.DELTA.C2 with seq. no. 23, by following the PCR methods described in Example 1-1 above. The resultant PCR product thus obtained was cloned into the protein expression vector pNKmut (Korean Patent 10-0985746) using DNA restriction enzymes NdeI and KpnI. (FIG. 2-2C).

[0091] To clone TRX(TEVc)-HPf.DELTA.C2 fusion protein composed of Thioredoxin A coupled with TEV protease recognition site, HPf.DELTA.C2 gene was obtained by running a PCR using HPf cDNA obtained from Example 1-1 as the template and seq. no 7 and 12 as primers by following the same PCR methods described in Example 1-1 above. TRX(TEVc)-HPf fusion protein-expression plasmid and HPf.DELTA.C2 gene produced by the PCR were digested by BamHI and KpnI DNA restriction enzymes, then HPf.DELTA.C2 was cloned into HPf gene-eliminated plasmid by substitution, yielding HGH(TEVc)-HPf.DELTA.C2 fusion protein-expression plasmid. (FIG. 2-2D).

[0092] TRX(TEVc)-HPf.DELTA.C1 and TRX(TEVc)-HPf.DELTA.C2 were transformed into E. coli strain for a scaled-up fermentation, then their respective protein expression was determined by using SDS-PAGE. Unexpectedly, those two smaller-version proteins, HPf.DELTA.C1 and HPf.DELTA.C2, were expressed as soluble protein forms in the cytoplasm while all HPf-containing fusion proteins are expressed as inclusion body forms (FIG. 3-2C).

[0093] The primers used for all PCR procedures are listed in the Table 1 below.

[0094] To express HPf and HPf.DELTA.C2 as fusion proteins coupled to a MBP (maltose binding protein) fusion partner, MBP-TEV fusion construct was synthesized as referenced in Paul, et al (2007) (GeneScript. USA). To facilitate the cloning of MBP with other genes to be expressed, MBP-TEV was modified by introducing DNA restriction enzyme sites NdeI, KpnI, and BamHI at the beginning, at the end, and in between MBP and TEV genes, respectively. (FIG. 2-3A).

[0095] The modified MBP-TEV gene was cloned into the protein-expression vector pNKmut (Korean Patent 10-0985746) plasmid by using DNA restriction enzymes NdeI and KpnI.

[0096] pNKmut plasmid containing MBP-TEV fusion construct was recovered and digested by DNA restriction enzymes BamHI and KpnI to remove the internal TEV gene. On the other hand, using SEQ ID. NO. 5 and 12 as primers, a HPf gene was obtained by following the PCR methods described above in Example 1-1. HPf gene thus obtained was digested by BamHI and KpnI, then inserted into the BamHI-KpnI digested pNKmut plasmid containing MBP to obtain MBP(TEVc)-HPf fusion protein-expression plasmid having the sequence identical to SEQ ID. NO. 24 (FIG. 2-3B).

[0097] By using TEV recognition site, MBP and its coupled HPf plasmid were transformed into the E. coli fermentation host, RZ4500 (Biotechnology Institute, Korea University, S. Korea), BL21(DE3) pLyS (Novagen, USA) and RosettaBlue(DE3) (Novagen, USA) cell lines. MBP(TEVc)-HPf fusion protein expression of the respective transformant was confirmed using SDS-PAGE. The result showed that BL21(DE3)pLyS transformant showed the highest level of MBP(TEVc)-HPf fusion protein expression in E. coli (FIG. 3-3).

[0098] To express HPf fusion construct coupled to HGH (human growth hormone) gene, HGH gene was obtained through running a PCR using HGH gene as the template (DNA-sequence ID: NM_000515.3) and SEQ ID. NO. 13 and 14 as primers by following the same PCR method as described above in Example 1-1.

[0099] MBP(TEVc)-HPf fusion protein-expression plasmid and HGH gene obtained through the PCR were digested by DNA restriction enzymes NdeI and BamHI, then HGH was cloned into the MBP-eliminated plasmid by substitution, yielding HGH(TEVc)-HPf fusion protein-expression plasmid with the sequence identical to SEQ ID. NO. 25 (FIG. 2-4). The cloned HGH(TEVc)-HPf fusion protein-expression plasmid was transformed into RZ4500 E. coli cell line (Biotechnology Institute, Korea University, S. Korea) for a scaled-up fermentation. It was observed that a large quantity of the fusion protein was expressed (FIG. 3-4A). It was also confirmed that HGH(TEVc)-HPf fusion protein was expressed as an inclusion body form within E. coli (FIG. 3-4B).

Supernatant from centrifugation of sonication-homogenized E. coli, 5: Supernatant collected by centrifugation of the inclusion body re-suspended by washing solution.

[0101] Expression of the full HSP90a protein (732 amino acids) was attempted in E. coli Partial carboxy-terminal fragment of full HSP90a gene was obtained by running a PCR using EST (Expressed Sequence Tag, clone id: IRCMP5012A0834D) clone containing full HSP90a gene (full coding region, DNA-sequence ID: NM_001017963) as a template and SEQ ID. NO. 16 and 17 as primers by following the same methods as described above in Example 1-1 (FIG. 2-5 A). The partial carboxy-terminal fragment of full HSP90a was subcloned into the plasmid pNKmut (Korean Patent 10-0985746) protein-expression vector by using DNA restriction enzymes NdeI and KpnI. To complete subcloning of the full HSP90a gene, another PCR was run again using the EST clone as the template and SEQ ID. NO. 15 and 16 as primers by following the same methods described above in Example 1-1 (FIG. 2-5A). The PCR products thus acquired was introduced into the NdeI DNA restriction enzyme-digested site of the plasmid containing c-terminal part of HSP90a, resulting in construction of the full HSP90a protein expression plasmid encoding the sequence of HSP90a identical with SEQ ID. NO. 26 (FIG. 2-5B).

[0102] Their sequences were analyzed using DNA sequencing confirming the 100% identity to the original sequences of TRX, MBP, hGH, and HPf. The recombinant cDNA constructs were expressed in the RZ4500 cell line (Biotechnology Institute, Korea University, S. Korea), BL21(DE3)pLyS (Novagen, USA), and RosettaBlue (DE3) (Novagen, USA) to obtain the transformants which were then cultured in 5 ml LB (Luria-Bertani) media at 37.degree. C. for 16 hrs.

[0103] The protein amount of expressed HPf, TRX(NGc)-HPf, TRX(TEVc)-HPf, MBP(TEVc)-HPf, and hGH(TEVc)-HPf were analyzed by SDS-PAGE, of which results reconfirmed the excellent expression of TRX(TEVc)-HPf gene in BL21 (DE3)pLyS. Therefore, this transformant is demonstrated to produce the recombinant TRX(TEVc)-HPf fusion protein in a large scale (FIGS. 3-1, 3-2, 3-3, and 3-4).

Example 2. Confirmation of the Expression of Recombinant Hpf Protein by Immunoblot

[0104] In order to further confirm whether the expressed recombinant protein described in the Example 1 is HPf, and originated from HSP90a, an immunoblot was performed (FIG. 4).

[0105] The transformants expressing the recombinant HPf, TRX(TEVc)-HPf, HGH (TEVc)-HPf, and full HSP90a genes were cultured in 5 ml LB media containing ampicillin by shaking at 37.degree. C. for 16 hours. The culture was centrifuged and the sample was analyzed with SDS-PAGE. The resulting electrophoresis gel was analyzed, first, by transferring proteins on the gel to PVDF filter (Millipore, USA) at 12V for 150 minutes by electrophoresis. Once the transfer is completed, the filter was then immersed in the blocking buffer (10% fat free milk and 0.02% Tween 20 and Tris saline buffer) for 1 hour to inhibit any nonspecific binding. Then the PVDF filter was immersed in the solution containing the HPf specific antibody (Rabbit anti-HSP90 antibody, CalbioChem, USA) at room temperature for 90 minutes. The nonspecific binding was eliminated by washing the filter for 10 min for three times in washing buffer (0.02% Tween 20 and Tris saline buffer). Subsequently the secondary antibody, goat anti-immunoglobulin antibody (HRP-linked, KOMA, Korea), was added to the reaction solution and incubated for 1 hour before the filter was washed with the washing buffer three times. By final staining with Chemiluminescence, LAS-4000 (Fuji, Japan) immunoblot results reconfirmed that the expressed protein was HPf. As seen in FIG. 4A, the recombinant HPf alone and recombinant TRX(TEVc)-HPf proteins were recognized by the antibody confirming their identity. The HGH(TEVc)-HPf and Full HSP90a recombinant protein was also recognized by the specific antibody, anti-HSP90a (FIG. 4B).

Example 3. Large Scale Preparation of HPf

[0106] The host cell line RX4500 transformed with the vector construct containing the HPf gene TRX(TEVc)-HPf as described in the Example 1 above, was used to determine the optimum conditions for the maximum expression of the recombinant protein. Specifically, the above RZ4500 transformant was cultured in an 1 liter flask, initially in 7 liter fermentator (FMT-07/C-B, Fermentec, Korea), which was gradually increased to final 50 L fermentator (FMT-50, Fermentec, Korea). The culture mixture of the 50 liter fermentator contains compositions described in the Table 2 below.

TABLE-US-00002 TABLE 2 Fermentation mixture for preparing the recombinant TRX(TEVc)-HPf protein Compounds % (W/V) NaHPO.sub.4 0.7 KH.sub.2PO.sub.4 0.3 NH.sub.4Cl 0.1 NaCl 0.05 NaNO.sub.3 0.1 Yeast extract 4 Glycerol 2 Water to 100 pH 7.2

[0107] The seed culture prepared with 1 ml RZ4500 transformed with TRX(TEVc)-HPf (glycerol stock) was added to 500 ml LB media (pH 7.4) in a 2 liter flask by shaking for 6 hours 37.degree. C. until the OD600 reached 0.5.about.0.6. For 50 liter fermentation, a subculture was prepared by mixing the seed culture and culture media in a ratio of 1:100.

[0108] The concentration of dissolved oxygen in the 50 liter culture was decreased gradually as the culture time increased. After 15 hours, the dissolved oxygen concentration remained in the culture was 10% of the concentration measured immediately after adding seed culture (FIG. 5). At that time 100-200 ml autoclaved 100% glycerol was added to the culture in order to supplement the carbon source for the host cell.

[0109] During the 15 hours of fermentation, a portion of culture was sampled every hour to analyze the pH, dissolved oxygen, and the O.D. values to determine the growth curve of the host cell (FIG. 5). When the O.D. reached 35-40, the fermentation was terminated. Also a portion of the culture was analyzed by SDS-PAGE and staining with Coomassie Brilliant Blue.

[0110] Subsequently, the expression level was quantitatively determined by measuring the protein concentration of the culture vs. the BSA (Bovine Serum Albumin, Sigma, USA) with predetermined concentrations using densitometer (Total Lab Quant, Totallab, USA). The concentration of the recombinant protein was 1 g/L.

Example 4. Purification and Optimization of the HPf Protein

[0111] The recombinant cells harvested from the large quantity fermentation was homogenized using homogenizer and washed in 0.5% Triton X-100 using ultracentrifuger (Hanil, Korea). The inclusion body was harvested by collecting the precipitate after removing the supernatant. Then it was dissolved in 25 mM NaOH, renatured with 1% acetic acid, and centrifuged. Only the supernatant was collected to remove impurities. Throughout the purification steps a portion of solutions was removed for analyzing by SDS-PAGE and Coomassie Brilliant Blue.

[0112] As seen in FIG. 6, HPf was expressed as TRX(TEVc)-HPf in the inclusion body rather than in the cytosol (lanes 4 and 5), of the host cell. Its protein structure remained intact during the denaturation with NaOH and renaturation with acetic acid (lane 7). Subsequently, TEV protease was added (TRX(TEVc)-HPf: protease=10:1) and incubated at 4.degree. C. for 24 hours to isolate the HPf from the TRX(TEVc)-HPf chimeric protein. The cleavage of the chimera by TEV protease was confirmed by SDS-PAGE as shown in lanes 8-11. The HPf protein was isolated by gel filtration chromatography (GFC).

[0113] Lanes of electrophoresis results of FIG. 6 indicate the proteins: 1. Marker proteins; 2. Competent cell (negative control); 3. Whole cell lysate; 4. Supernatant fraction after the homogenization (cytosol fraction); 5. Pellet obtained after homogenization (inclusion body fraction); 6. Supernatant after washing the pellet; 7. Dissolved inclusion body; 8-11 Solubilized inclusion body treated with TEV protease. The purity of purified HPf was >95% as determined by HPLC and SDS-PAGE. The yield after the purification was determined to be 0.1-0.2 g/liter (FIG. 7).

Example 5. Analysis of HPf by MALDI-TOF

[0114] In order to ensure that the HPf protein from the final purification step was originated from HPS90a, the MALDI-TOF analysis (Voyager-DE STR, Applied BioSystems, USA) was performed. After the electrophoresis of purified HPf (FIG. 7b), the bend corresponding to HPf was cut out from the gel with a sharp razor. Then the gel was immersed in 0.1 M (NH.sub.4)HCO.sub.3 solution for 1 hr. After the supernatant was removed, the gel was transferred to 50% acetonitrile in 0.1 M (NH.sub.4)HCO.sub.3 solution for 1 hr, then in 100% acetonitrile for 15 minutes. Then the in-gel trypsin digest was performed by mixing the gel with protein-sequencing-grade trypsin (Promega, USA) in 25 mM (NH.sub.4)HCO.sub.3 for 16 hours at 37.degree. C. Subsequently 5% TFA solution containing 60% acetonitrile was added to terminate the reaction and the mixture was centrifuged. The supernatant was retrieved to determine the molecular weight by the MALDI-TOF analysis. According to the analysis using the protein mass database, the purified protein HPf is a fragment of HSP90a (FIG. 8).

Example 6-1. Analysis of the HPf Particle Size

[0115] In order to prepare the nano-liposome encapsulated HPf for the pharmaceutical/cosmetic formulation the HPf particle size was measured using Electrophoretic Light Scattering Spectrophotometer, ELS-8000.

[0116] HPf from the final purification step was diluted to 1 mg/ml (or higher concentration) in phosphate buffered saline; pH 7.2, the light scattered intensity, the weight and number of particles were determined using ELS 8000. As shown in the FIGS. 9A-9C, the diameter of the particle was measured to be approximately 10-14 nm. The diameter of the three dimensional structure of HPf monomer was approximately 4.4 nm based on the analysis using the software UCSF Chemera program.

[0117] Since the size of monomer and the HPf in solution could be different due to its tendency to oligomerize in solution, its size in solution was measured by gel filtration chromatography. The results demonstrating the peak of HPf immediately following the Blue Dextran (200 kDa, Sigma-Aldrich, USA) indicated that HPf does exist in solution as an oligomeric form (FIG. 9-ID).

Example 6-2. HPf Protein-Size Analysis Via Electron Microscopy

[0118] By using a transmission electron microscope (EF-TEM; Energy Filtering-Transmission Electron Microscope, KB SI, Korea), HPf protein particle's size and image were analyzed. The first fixation process was completed by using a 2.5% glutaraldehyde and 4% paraformaldehyde solution, and it was washed with a phosphate buffer solution. Then, the second fixation process was done using with 1% osmium tetroxide, and underwent dehydration steps beginning with 60% ethanol, onto 70%, 80%, 90%, 95% and 100% in ascending order. After embedding with epoxy resin, sample sections were prepared by thin microslicer. Grids were prepared for section platform, and samples were observed after the electrostaining steps. (FIG. 9-2).

Example 7. Evaluation of the Safety of HPf Using Skin Cell Lines

[0119] To determine whether HPf is safe for human application, human epidermal cell line (HaCaT) (Schoop, Veronika M., Journal of Investigative Dermatology., 112 (3):343-353, 1999) and dermal cell line (HEF) (CRL-7039, ATCC, USA) was incubated with HPf. The concentration of HPf used for testing the toxicity was 10-100 times higher than the concentration of epidermal growth factor used in cosmetic products manufactured and marketed by Regeron Inc. (1-10 .mu.g/ml EGF used for the Clairesome-EF product line). Specifically, in 96 well plate 2.about.10.times.10.sup.3 cells of each cell line were plated and cultured in DMEM media (Hyclone, USA) containing 10% FBS (Fetal Bovine Serum Albumin, Hyclone, USA). HPf was then added to each cell at the concentration of 0, 0.0001, 0.001, 0.01, 0.1, 0.5, 1, 5, 50 and 100 .mu.g/ml, and the plate was incubated at 37.degree. C. in the CO.sub.2 incubator for 1 week. The growth rate (%) of cells was determined by mixing 10 .mu.l culture media with 5 mg/ml MTT (3-(4,5-dimethylthiazol-2-yl)-2,5 diphenyltetrazolium bromide, Sigma-Aldrich, USA) and incubated at 37.degree. C. in CO.sub.2 incubator for 4 hours. After the insoluble MTT precipitate was dissolved in 10% Triton X-100 and 0.1N HCl the O.D. was measured using spectrophotometer, spectra MAX 190 (Molecular Device, USA) at 595 nm. The cells mixed with 100 .mu.g/ml of HPf maintained the 90% survival rate (FIG. 10A) after incubation for 24 hours, and 85% after 7 days incubation (FIG. 10B). The results indicated that HPf can be safely used as a cosmetic or pharmaceutical ingredient.

Example 8. Stability of HPf in Aqueous Solution

[0120] In order to find out how to prevent the physical/chemical instability and the loss of bioactivity of HPf in aqueous solution, the stability of HPf was measured when dissolved in pH 7.2 phosphate buffer solution or kept in a gel state. The gel used for this analysis was prepared by mixing the following compounds. Care was taken to exclude any potentially interfering factors that affect the stability of HPf protein.

TABLE-US-00003 TABLE 3 Composition of the el used for evaluation of the HPf stability Compounds Amount (%) KOH 0.28 carbomer 0.4 Glycerin 10 phenoxyethanol 0.6 HPf 1 mg/ml Water 88.72

[0121] The stability was evaluated as follows; first, HPf was diluted to 10 .mu.g/ml in phosphate buffer or to 1 mg/ml while tested in the gel state. The solution or the gel was left at 4.degree. C. or 37.degree. C. for one month. The amount and/or the denaturation of the protein was analyzed using Coomassie Brilliant Blue and SDS-PAGE with samples collected on 3, 7, 14, and 30 days from the first day of the experiment. The protein stability was measured using a densitometer (TotalLabQuant, Totallab, USA). As seen in the FIG. 11, the HPf was consistently stable while kept in phosphate buffer or in the gel state at 4.degree. C. and 37.degree. C. for one month.

Example 9. Evaluation of the Efficacy of HPf for Treating Atopic Dermatitis Using Cell Line Models (Anti-Inflammatory Effects of HPf Through Suppressing the Degranulation)

[0122] Degranulation of mast cells mediated by IgE is one of the typical symptoms of atopic dermatitis. To evaluate the anti-inflammatory effect of HPf, its activity of inhibiting the secretion of beta hexosaminase, a biomarker for degranulation, was measured using a basophilic cell line RBL-2H3 (CRL-2256, ATCC, USA). First, 2.5.times.10.sup.5 RBL-2H3 cells were plated in each well of 48 well plate and incubated at 37.degree. C. in CO.sub.2 incubator for 3 hours. Cells were sensitized by adding IgE to 1.0 .mu.g/ml and incubated for 24 hours. Then the unbound IgE was removed by washing the cells with HBS (HEPES buffered Saline) 4 times. Cells were then stimulated by treating with 800.about.1000 ng/2,4-dinitrophenyl hapten-human serum albumin (DNP-HSA, Biosearch Technologies, USA). Then 50 fl of the supernatant was mixed with 200 fl 0.05M citrate buffer (pH 4.5) containing ImM p-nitrophenyl N-acetyl-beta-glucosamine and left for 1 hour. The reaction was terminated by adding 500 fl 0.05M sodium carbonate buffer (pHIO). The O.D was measured at 405 nm using spectrophotometer. The results demonstrated (FIG. 12) that 100 .mu.g/ml HPf inhibited the secretion of beta hexosaminase by 60% when the inhibitory effects were compared with that of the control (treated with PBS). This indicates that HPf is able to significantly ameliorate symptoms of atopic dermatitis by suppressing the degranulation through inhibiting of the beta hexosaminase secretion.

Example 10. Evaluation of the Efficacy of HPf for Treating Atopic Dermatitis Using Animal Model

[0123] 10-1) Effects on the Wound Healing

[0124] Atopic dermatitis was induced on the skin of NC/Nga mouse by topical administration of 150 .mu.l of 0.15% 2.4-dinitrofluorobenzene (DNFB) (dissolved in acetone:olive oil=3:1) once a week for 4 weeks. The wound healing effects of HPf was determined as follows: first, mice were divided into two groups; one group received topical administration of 100 .mu.l HPf three times per week for 4 weeks, whereas the control group did not receive HPf. (see FIG. 13A for the scheme of the treatment). The degree of skin damage (wound) was determined by the naked eye (FIG. 13B), while the infiltration of immune cells and their recovery were measured by dermal tissue staining (FIG. 14). Compositions either with or without HPf used for the topical administration was prepared as gel in order to keep the HPf stay on the applied area.

TABLE-US-00004 TABLE 4 Composition of the gel used for evaluation of the HPf efficacy on treating atopic dermatitis. Amount (%) HPf treated Compounds Control group KOH 0.28 0.28 Carbomer 0.4 0.4 Glycerin 10 10 Phenoxyethanol 0.6 0.6 HPf -- 1 mg/ml Water 88.72 88.72

[0125] Throughout the animal test period, no skin disorders induced by DNFB were developed except the atopic dermatitis. A topical administration of DNFB on the skinned back of Nc/Nga mouse induced the separation of stratum corneum and inflammation due to the wound (FIG. 13B-2). After 4 weeks of treatment, skin of the treated group, i.e., the group that received DNFB+HPf (FIG. 13B-4), appeared virtually wound-free with a slight mark of keratosis, while the control group demonstrated serious wound left with a visible sign of inflammation and severe keratosis (FIG. 13B-3). These results indicate the efficacy of HPf for ameliorating the symptom of atopic dermatitis.

[0126] 10-2) Effects of HPf for Wound Healing and for Suppressing the Infiltration of Immune Cells into the Skin Area Affected by Atopic Dermatitis as Shown in Animal Model

[0127] In order to further evaluate the ability of HPf to heal wounds on Nc/Nga mouse with atopic dermatitis, a peace of skin tissue was cut out after 4 weeks from the treatment and stained with H&E (Hematoxylin & eosin) (FIG. 14). Results demonstrated a marked separation of stratum corneum in the group received DNFB only (FIG. 14A-2, 14B-2) or the control group (FIG. 14A-3, 14B-3) without treatment with HPf, while the skin damage was minimal in the group treated with HPf (FIG. 14A-4, 14B-4) (See the Table 4 for compositions used for the control group). Atopic dermatitis is known to cause the infiltration of immune cells around the affected areas since it tends to secrete various chemoattractive cytokines. According to the H&E staining experiment, the group received DNFB only and the control group without HPf shows the infiltration of immune cells (FIGS. 14A-2, 14B-2 and 14A-3, 14B-3), whereas such an infiltration was minimal in the group treated with HPf (FIG. 14A-4, 14B-4). The results strongly suggest that HPf is capable of suppressing the infiltration of excessive immune cells to the affected areas as well as healing the wound.

Example 11. Effects of HPf on Skin Cell Differentiation

[0128] Effects of HPf on the cell differentiation of keratinocyte and fibroblast was evaluated using human epidermal cell line HaCaT (Schoop, Veronika M, Journal of Investigative Dermatology., 112(3):343-353) and fibroblast cell line CCD-986sk (SCRL-1947, ATCC, USA). After each cell line was treated with HPf (100 .mu.g/ml) for 24 hours RNA was extracted and qRT-PCR (SYBR-Green) was performed.

[0129] Specifically, 0.3.times.10.sup.6 cells/ml were plated in 6 well plates, which was incubated in DMEM (Hyclone, USA) containing 10% FBS until cells reached the 70-80% confluency at 37.degree. C. in C0 2 incubator. The above cells were treated with HPf to achieve 100 .mu.g/ml as the final concentration and incubated 24 hours. After removing the supernatant, 1 ml TRizol solution (Invitrogen USA) was added to dissolve the cells. Then 200 fl chloroform was added followed by vortexing for 10 sec. and centrifuged at 12,000.times.g (Centrifuge 5418, Eppendorf, USA) for 15 minutes. The supernatant was collected in a new e tube and mixed with 0.5 ml isopropyl alcohol and recentrifuged for 10 min. to precipitate the total RNA. The total RNA was washed with 70% ethanol once then dissolved in water free of RNAse and DNAse. Such purified RNA was used to construct the cDNA library. The cDNA was synthesized using Omniscript Reverse Transcription kit (Qiagen, U.S.A.) following the instruction provided in the manufacturer's manual.

[0130] First, the total RNA 1 .mu.g, IX RT buffer, dNTP mix, oligo-dT primers, RNAse inhibitors and Omniscript Reverse Transcriptase were mixed, then water free of DNase and RNase was added to adjust the volume to 20 .mu.l, which then was incubated at 37.degree. C. for 60 minutes to obtain cDNAs.

[0131] The expression level of marker genes, such as keratin 10 (KRT10), transglutaminase 1 (TGM1) and involucrin (IVL), which represents the degree of cell differentiation were determined by RT-PCR (LightCycler 480, Roche, USA). Sequences of the primers for RT-PCR are shown in the Table 5. Reagents for the RT-PCR were SYBR green PCR master mix purchased from Applied Biosystem. The PCR was initiated by denaturation at 95.degree. C., 10 seconds, followed by annealing at 60.degree. C., 10 seconds and amplification at 72.degree. C., 10 seconds. The cycle was repeated for 45 times.

[0132] The melting curve analysis was performed at the final cycle of the RT-PCR to confirm the absence of nonspecific bands. The RT-PCR products were analyzed ddCt algorithm (A-A-Ct) and the results are demonstrated in FIG. 15. They indicate that when HaCaT cells were treated with HPF, the expression level of marker genes for cell differentiation was 20-250 higher than that of the control cell (FIG. 15A). In the case of CCD986-sk cell, the expression level of marker genes was 20 times higher than that of the control cells (FIG. 15B) when treated with HPf.

[0133] These results suggest that HPf plays important role in controlling skin cell differentiation hence can be effectively used as an active ingredient in wound healing medicine and/or cosmetic products.

Example 12: Effects of HPf on Subcutaneous Fat Cell Differentiation In Vitro

[0134] Subcutaneous fat cells secrete various factors necessary to maintain their structure properly and contain cells that are yet to be differentiated, such as pre-adipocytes and fat stem cell. We carried out experiments to find out whether HPf might promote or suppress the fat cell differentiation. After 3T3-L1 cell line (CL-173, ATCC, USA) was treated with HPf (100 ug/ml) or with PBS (pH 7.2) for the control, cells were stained with Oil Red 0 stain in order to determine the effect of HPf on the fat cell differentiation. As seen in FIG. 16, cells treated with HPf display 40% reduction in the fat cell differentiation when compared to that of control cells.

[0135] The present preparations and formulations comprising these formulations may be used in methods and in specialty preparations for reducing and/or inhibiting the formation of subcutaneous fat deposits in an animal, such as in a human.

Example 13. Evaluation of Skin Condition Improving Effects of HPf Using Artificial Skin

[0136] The present inventors have investigated the effects of HPf on skin conditioning using artificial skin which has a very similar 3D structure to human skin. The 3D artificial skin culture was carried out using the Neoderm ED product (TEGO Cell Science Inc., Korea) by following the protocols provided by the manufacturer. Neoderm ED product has epidermal and dermal tissue structure that is similar to human, hence has been frequently utilized for developing novel pharmaceuticals for skin as well as cosmetic products.

[0137] After collagen matrix and fibroblast cells were grown with media on the surface of cell culture vessels, keratinocytes were plated on the surface and cultured for 4 days to obtain monolayer cell. The monolayer of dermal cell was induced by exposing the cells to air for 16-20 days. Subsequently the artificial dermal layer was treated with 100 .mu.g ml HPf or with phosphate buffered saline (Ph 7.2) for 7 days. Then the epidermis and dermis were stained with H&E stain. FIG. 17 demonstrates that there are no changes in the thickness of epidermal layers in the control (FIG. 17 A-CI-C3) and HPf treated groups (FIG. 17 B-HI-H4), while the HPf treated group displayed 2-fold increase in the thickness of dermal layers when compared to the control groups. This results clearly indicate that HPf promote the cell differentiation and growth of dermal layer, implicating that the expression of major skin tissue components, such as collagen and elastin may be induced by HPf.

[0138] Therefore, HPf can be used as an active ingredient for improving wrinkles or elasticity, and for developing skin condition improving cosmetic products.

Example 14. Effects of HPf on Inhibiting Melanin Biosynthesis

[0139] Inhibitory effects of HPf on the melanin biosynthesis were examined in order to determine whether HPf might be effective on skin whitening. After B16F10 cell line (CRL-6475, ATCC, USA) was treated with HPf (IOO.mu.{circumflex over ( )}.SIGMA..tau.I) or PBS for 48 hours. The cell survival rate and melanin biosynthesis were measured by MTT assay as shown in FIG. 18. The addition of 100 .mu.g/ml HPf into the culture reduced the melanin biosynthesis 70% when compared to the control, suggesting that HPf has strong effect on skin whitening. In a safety test, 100 .mu.g/ml HPf did not affect the survival of cells indicating no toxicity of HPf at this concentration.

Example 15. Manufacture of Lipo-HPf, HPf Encapsulated in Nano-Liposomes

[0140] The following materials were used for manufacturing Lipo-HPf; soybean lecithin (Shindongbang Inc., Korea) as the phospholipid, Metarin P (Degussa Texturant Systems Deutschland GmbH & Co. KG), Nutripur S (Degussa Texturant Systems Deutschland GmbH & Co. KG) or Emultop (Degussa Texturant Systems Deutschland GmbH & Co. KG).

[0141] The heat exchanger of a high-pressure homogenizer (max. output 5 L/hr, highest pressure 1200 bar, Model HS-1002; manufactured by Hwasung Machinery Co., Ltd., South Korea) was placed in ice water such that the temperature of the outlet of the homogenizer did not exceed 30.degree. C., In the meantime the inside of the homogenizer was then washed with distilled water so as to be ready to operate. Then, HPf was dissolved in a buffer solution (20 mM NaH.sub.2PO.sub.4 pH 6.5-7.5, 1 mM EDTA) at a concentration of 1 mg/ml, phospholipid was added at a ratio of 10 w/v % and sufficiently hydrated and stirred. The stirred solution was passed through the homogenizer three times or more at room temperature and a low pressure of 0 bar. To the solution passed through the homogenizer, phospholipid was added to a ratio of 14 w/v % and sufficiently hydrated and stirred. The stirred solution was passed through the homogenizer three times or more at 100 bar. Then, to this solution phospholipid was added to a ratio of 18 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 200 bar. Then, to this solution phospholipid was added to a ratio of 20 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 300 bar. Then to this solution, phospholipid was added to a ratio of 22 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 400 bar. Then, to the solution passed through the homogenizer in the condition of 400 bar, phospholipid was added to a ratio of 24 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 500 bar. Then, to the solution passed through the homogenizer in the condition of 500 bar, phospholipid was added to a ratio of 26 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 600 bar. Then, to the solution passed through the homogenizer in the condition of 600 bar, phospholipid was added to a ratio of 28 w/v %, sufficiently hydrated and stirred, and passed through the homogenizer three times or more at 700 bar. Then this solution was passed through the homogenizer three times or more at 800 bar followed by centrifugation at 15,000.times.g for 30 minutes. The supernatant was then passed through gel chromatography (GE Healthcare, USA) to eliminate HPf which was not encapsulated by liposome, hence preparing HPf-containing liposome (Lipo-HPf) liquid formulation.

[0142] For a topical preparation, it is envisioned that the product will include an effective dose estimate of about 100 ng/ml to about 1 mg/ml of each of the HPf polypeptide, the polypeptide fragments, or a mixture thereof.

Example 16--Drug Delivery Systems (DDS) of Hsp90a and/or Hsp90a Fragments

[0143] The present example relates to dissolvable microneedle (DMN) formulations of the heat shock protein preparations that have parameter dependent conditional monomeric, dimeric and multimeric association/dissociation/aggregation profiles. In particular, the heat shock protein Hsp90a and Hsp90a fragments provided herein are formulated to provide a product of the Hsp90a and/or Hsp90a fragments in a multitude of dissolvable needles, and in this manner, provide maximal delivery of the active ingredient to a skin surface to which it is applied.

[0144] Facial mask formulations that include the micro-needle DMV formulations of heat shock protein 90a, Hsp90a fragments, or any combination of these as described herein, are contemplated as a particular commercial embodiment.

[0145] The drug delivery systems also include parameter dependent conditional monomeric, dimeric and multimeric association/dissociation/aggregation profiles of Hsp90a and Hsp90a fragments. By way of example, some of these formulations may include noisome formulations, NLC formulations, exosome-liposome fusion formulations, SLN formulations, NLC formulations, nanoemulsion formulations, colloidal dispersion formulations and sprayable formulations.

[0146] Combination products/formulations catered to mesotherapy devices (microneedle rollers, microinjectors, ultrasonic cavitation, electroporation, RF-, HF-, sonic vibration massage rollers, microdermabrasion, laser treatment) may also be provided that contain the active ingredient Hsp90a and/or Hsp90a fragment components described herein, such as the HPf polypeptide, HPf.DELTA.C1, HPf.DELTA.C2, and other fragments and/or fusion products thereof, to provide delivery of the desired single agent or combination agent desired.

[0147] Dissolvable microneedle formulations of the present active ingredients may be prepared according to those techniques known to those of skill in the art, such as those techniques described in Moga et al. (2013) (Advanced Materials, 25 (36): 5060-5066).

[0148] Biodegradable microneedles are typically made by filling a mold with a matrix containing the drug of interest; generally, multiple vacuum and centrifugation steps are required to completely fill the molds, arduous steps that lead to lengthy fabrication times and pose issues to scale-up manufacturing. A thick substrate, or backing layer, is attached to the array of microneedles to form a patch. After preparing microneedle patches, they generally are administered by placing on a skin surface. Conventionally, the microneedle patch is applied topically to pierce the skin and penetrate into the viable epidermis or dermis depending on the physical dimensions of the needles. Due to skin's elastic qualities, the entirety of the needle does not enter the skin. The needles are left in the skin for the duration of the treatment period, from minutes to hours, and the substrate is then removed, extracting all parts of the needle that have not yet dissolved (usually 5-20% of each microneedle).

Example 17--Method Development of Functional Assay or BioAssay for In Vitro Hsp90a or Hsp90a Fragments

[0149] The present example presents an in vitro functional assay or bioassay for assessing Hsp90a or Hsp90a fragment activity.

[0150] In some embodiments, the functional assay may include a reference and/or control substrate comprising the Hsp90a, HPf, HPf.DELTA.C1, or HPf.DELTA.C2 peptide.

Example 18--Methods of Treatment

[0151] The present example presents methods of using the formulations of Hsp90a and Hsp90a fragments as part of a therapeutic treatment, alone or together with other therapeutic agents or treatment modalities. For example, with different Growth Factor fusion protein partners (for example, growth factors include human growth factor (hCG), EGF, FGF, NGF, PDGF, VEGF, IGF, GMCSF, GCSF, TGF, Erythropieitn, TPO, BMP, HGF, GDF, Neurotrophins, MSF, SGF, GDF, to name a few), may be used together with Hsp90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2, d/or Hsp90a fragments to provide a combination ingredient for therapeutic use and patient management.

[0152] By way of example, a therapeutic treatment incorporating Hsp90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2, and/or Hsp90a fragments, in a medicament, alone or prepared as a fusion protein in with a fusion partner protein that is a growth factor (for example, a fusion protein of the Hsp90 component together with any one or more of the growth factors recited above, as appropriate), for treatment of the following conditions:

1) Chronic Wounds (Diabetic foot ulcer, Bed sore, etc.), for example, alone or together as a topical formulation; 2) Obesity. For example, the Hsp90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2, and/or Hsp90a fragment may be incorporated in a dissolvable microneedle patch preparation, and this preparation may take the form of a patch or body wrap that may be provided to a skin area or site on a patient. In this manner, the Hsp90a active ingredient may be delivered to the patient to reduce fat deposits on the applied area.

Example 19--Hsp90a and Tau Degradation-Associated Disease, Co-Chaperones of Hsp90 and Hsp70

[0153] The present example relates to the use of Hsp90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2, and/or a Hsp90a fragment as part of a treatment preparation for inhibiting or treating neurodegenerative diseases (NDD), particularly those associated with tau degradation. For example, one such neurodegenerative disease associated with tau degradation is Alzheimers disease (AD).

[0154] Hsp90a, HPf, HPf.DELTA.C1, HPf.DELTA.C2, and/or fragments thereof, may inhibit formation of a complex of Hsp90 that protects against tau degradation. For example, inhibitors of Hsp90 have been reported to decrease levels of phosphorylated tau (Dickey et al., 2006). Thus, the present investigators provide that Hsp90 may be used to inhibit the levels of degraded tau levels in a patient by protecting hyperphosphorylated tau species from degradation.

[0155] A complex of Hsp90 with the co-chaperone FKBP51 was reported to protect tau from proteasomal degradation and correlated with the neurotoxic tau species (Jinwal et al., 2010; Blair et al., 2013). It has also been reported that FKBP51 expression is increased with age and in Alzheimers disease (Blair et al., 2013). Speculation was thus made that Hsp90 interaction with FKBP51 is altered in aging brains and Alzheimers disease brains, allowing for the preservation of soluble, but possibly neurotoxic protein species. Another member of FKBP family, FKBP52, may also be involved in tau-related neurodegeneration. It has been suggested that FKBP52 is a regulator of tau association with microtubules, specifically that FKBP52 inhibits tau association with microtubules (Chambraud et al., 2010). A reduction in tau-mediated neurite outgrowth has been reported in cells overexpressing FKBP52 (Chambraud et al., 2010).

[0156] The roles of Hsp70, Hsp90, and the co-chaperone STI1, all of which affect protein folding, will be employed in combination in the development of Alzheimer disease and other disease (protein folding disease) therapeutics. The unique cytokine-like activities of STI1 will be incorporated in these treatment strategies. Both the extracellular and intracellular activities of STI seem to converge to increase cellular resilience (Beraldo et al., 2013). The role of some co-chaperones of Hsp70 in protein misfolding associated with disease, such as the co-chaperone CHIP, and in high molecular weight immunophilins, will be used in the development of appropriate strategies for treatment of protein-misfolding diseases, as well as other diseases associated therewith.

[0157] Hsp70 promotes tau stability and associates with microtubules at high levels of expression (Dou et al., 2003; Jinwal et al., 2009). STI1 may also be important for protection against aberrant tau species, as its downregulation in fruit flies has been reported to worsen tau-induced retinal degeneration (Ambegaokar and Jackson, 2011). Upregulation of both Hsp70 and Hsp90 increases tau association with microtubules (Dou et al., 2003). Soluble levels of tau correlate with those of Hsps and their co-chaperones, while in tauopathies where total levels of tau increase, Hsp70/90 decrease (Dou et al., 2003). Overall, tau regulation by the Hsp machinery is very complex and careful analysis of all possible effects on tau is needed when considering an anti-Alzheimers disease therapy that modulates this machinery.

[0158] Hsp70 and Hsp90 both interact with many co-chaperones containing tetratricopeptide repeat (TPR) domains, which consist of three or more 34-amino acid residues (Lamb et al., 1995). These motifs form anti-parallel a-helices (Allan and Ratajczak, 2011) that bind to the C-terminus of the chaperone and are the main interaction site for co-chaperones (Smith, 2004), along the EEVD peptide motif on Hsp70 and Hsp90 (Kajander et al., 2009). Proteins containing TPR domains typically share no other sequence homology, but are commonly found to be involved in regulation of cell cycle, protein trafficking, phosphate turnover, and transcriptional events (Blatch and Lassle, 1999). TPR domain-containing co-chaperones regulate the ATP cycle of chaperones and aid in client transport to binding pockets, where they are folded. Hsp40 may help coordinate other co-chaperones in binding Hsp70, such as Hsp70-interacting protein (Hip; Hohfeld et al., 1995) in the early stages of the chaperone cycle, as well as STI1 and SGT (Allan and Ratajczak, 2011). STI1 is also a co-chaperone for Hsp90, along with p23, Cdc37, and the immunophilins peptidyl-prolyl cistrans (PPIases) isomerases FKBP51 and FKBP52, phosphatase PP5 and the cyclophillin Cyp40 (Allan and Ratajczak, 2011). Some of these co-chaperones inhibit Hsp90 ATP turnover (Rehn and Buchner, 2015). C-terminal Hsp70-interacting protein (CHIP) is also a co-chaperone for both Hsp70 and Hsp90.

[0159] Both upregulation of Hsp70 and inhibition of Hsp90 in mammals reduce protein aggregation and toxicity. STI should be further investigated in models of protein aggregation, as STI1-PrPC interaction results in neuroprotection, attenuates AbO toxicity, and STI1 is an irreplaceable co-chaperone for the Hsp70/Hsp90 machinery.

Example 20--Hsp90a and Anti-Cancer Formulations

[0160] The present example provides for the use of Hsp90a and Hsp90a fragments in anti-cancer therapeutics. Hsp90a is expected to provide selective inhibition/affinity against Hsp70/90 co-chaperones-clients complex, which is enriched in numerous malignant cell models that are absent in normal cells. By inhibition of this complex, malignant cells may be inhibited, along with the cancer linked to the identified malignant cell type.

[0161] The purine derivative PU-H71 possesses unique selectivity amongst Hsp90 inhibitors, preferentially targeting high molecular-weight complexes composed of Hsp70/90 and various co-chaperones and client proteins, which are enriched in numerous malignant cell models, but absent in nononcogenic tissue (Moulick et al., 2011; Rodina et al., 2016). The formation of these large stable chaperone species appears to be cancer specific and diagnostic proteomic approaches may serve as a method to clinically screen patients that are most likely to benefit from targeting such species. Whether large and stable chaperone complexes with misfolded proteins occur in different neurodegenerative diseases is under study. Therapeutic approaches targeting chaperones involved in the Hsp70/90 co-chaperones-clients complex in cancer cells are proposed in the present example.

[0162] Hsp70 and Hsp90 both interact with many co-chaperones containing tetratricopeptide repeat (TPR) domains, which consist of three or more 34-amino acid residues (Lamb et al., 1995). These motifs form anti-parallel a-helices (Allan and Ratajczak, 2011) that bind to the C-terminus of the chaperone and are the main interaction site for co-chaperones (Smith, 2004), along the EEVD peptide motif on Hsp70 and Hsp90 (Kajander et al., 2009). Proteins containing TPR domains typically share no other sequence homology, but are commonly found to be involved in regulation of cell cycle, protein trafficking, phosphate turnover, and transcriptional events (Blatch and Lassle, 1999). TPR domain-containing co-chaperones regulate the ATP cycle of chaperones and aid in client transport to binding pockets, where they are folded. Hsp40 may help coordinate other co-chaperones in binding Hsp70, such as Hsp70-interacting protein (Hip; Hohfeld et al., 1995) in the early stages of the chaperone cycle, as well as STI1 and SGT (Allan and Ratajczak, 2011). STI1 is also a co-chaperone for Hsp90, along with p23, Cdc37, and the immunophilins peptidyl-prolyl cistrans (PPIases) isomerases FKBP51 and FKBP52, phosphatase PP5 and the cyclophillin Cyp40 (Allan and Ratajczak, 2011). Some of these co-chaperones inhibit Hsp90 ATP turnover (Rehn and Buchner, 2015). C-terminal Hsp70-interacting protein (CHIP) is also a co-chaperone for both Hsp70 and Hsp90.

[0163] This system of co-chaperones implicated in the formation of the Hsp70/90 co-chaperones-clients complex will be targeted in the development of strategies for treating specific types of cancers identified to have a malignant cell population that demonstrates an inhibition of this complex formation upon exposure to one or a combination of inhibitory molecules, such as a molecule capable of diminishing and/or competing with co-chaperones of Hsp90 or Hsp70, such as CHIP and/or STPI1, necessary for complex formation.

Example 21--Hsp90a and Prion Degradation in Disease

[0164] Hsp90a fragments may inhibit formation of a complex of Hsp90 that protects a-synuclein (in case of PD), huntingtin (in HD), SOD1/TDP-43, and/or prion degradation (PD). Hsp90 inhibition with geldanamycin in human cell lines has been shown to counteract formation and accumulation of a-synuclein oligomers and alleviate a-synuclein-induced toxicity (Klucken et al., 2004; McLean et al., 2004; Flower et al., 2005; Luk et al., 2008). Much less is known about the role of Hsp90 in regulating a-synuclein aggregation. In vitro experiments have been reported to demonstrate that Hsp90 can abolish a-synuclein binding to vesicles and promote fibril formation in an ATP-dependent manner (Falsone et al., 2009). Other in vitro studies investigating Hsp90 interaction with the A53T mutant of a-synuclein report that all three Hsp90 domains bind to and prevent A53T a-synuclein aggregation. However, Hsp90 could not bind to monomeric or fibrillary synuclein species in this model (Daturpalli et al., 2013).

[0165] STI is capable of having some of its own chaperone-like activity, but interaction with Hsp70 or Hsp90 would have a greater effect on reorganization of toxic a-synuclein species. The literature reports that increasing Hsp70 levels by activating the heat shock response or by genetic manipulation would be a suitable method for reducing a-synuclein toxicity.

[0166] Huntington's Disease (HD): In C. elegans expressing the Q35 aggregate prone-protein, siRNA for Hsp40, Hsp70, Hsp90, or STI1 was reported to increase the number of Htt aggregates (Brehme et al., 2014). Chaperones and co-chaperones are presented here to provide therapeutic targets for HD, used in conjunction with Hsp90, Hsp90a, or the fragments.

[0167] Amyotrophic lateral sclerosis (ALS) is a group of rare neurological diseases that mainly involve the nerve cells (neurons) responsible for controlling voluntary muscle movement. There are a number of proteins, RNAs and miRNAs dysregulated in ALS. The first aggregated protein to be identified was Cu/Zn superoxide dismutase (SOD1; Rosen et al., 1993), then trans-active DNA binding protein-43 (TDP-43; Arai et al., 2006; Neumann et al., 2006), along with fused in sarcoma/translocated in liposarcoma (FUS; Kwiatkowski et al., 2009; Vance et al., 2009), see Blokhuis et al. (2013) for a more extensive review on toxic protein accumulation in ALS.

[0168] Both Hsp70 and Hsp90 can be co-immunoprecipitated with TDP-43. Moreover, knockdown of Hsp70 or Hsp90 in human neuroblastoma cells lead to a significant increase in C-terminal and phosphorylated TDP-43, which are toxic TDP-43 species known to aggregate in the cytoplasm (Zhang et al., 2010). Treating HeLa cells with celastrol, an Hsp90 inhibitor, reduced levels of full length TDP-43, specifically by impairing Cdc37 (an Hsp90 co-chaperone which aids in client protein docking; Lotz et al., (2003), Hsp90 interaction with TDP-43 (Jinwal et al., 2012), Prion). Specifically, STI1 coordination of Hsp70 and Hsp90 was responsible for this prion elimination activity, as mutations in the TPR1 and TPR2 domains of STI1 lead to a drastic increase in PSI+ propagation. This suggests that STI1 coordination of Hsp70-Hsp90 as well as Hsp104 activity is required for disaggregation of yeast prions. Furthermore, STI expression and activity was also found to reduce toxicity of Rnq1 (a yeast protein with a glutamine-rich prion domain) prions, RNQ+ (Wolfe et al., 2013). STI1 recruited RNQ+ prions to foci containing Hsp104, amyloid like proteins and Hsp40, ultimately buffering toxicity by these prions. The role of Hsp90 and its co-chaperones in prion diseases is virtually unknown. STI1 can signal via the prion protein as discussed above, and prion infection in cells abolishes STI1 signaling via the prion protein (Roffe et al., 2010). Interaction of Hsp90 with STI1 also decreases PrPC-dependent STI1 neuroprotection (Maciejewski et al., 2016). Secreted Hsp90 may interfere with STI interaction with PrPC. STI1 regulates protein aggregates via its co-chaperone activity (Wolfe et al., 2013). STI1 also has extracellular cytokine-like neurotrophic function. The effects of STI1 on prion diseases and other neurodegenerative diseases are complex. The present investigators propose treatment regimens that target the aggregation of these proteins, and provides an intervention targeting the chaperone machinery toward refolding or degradation.
