Abstract
Description
[Technical field]
[0001] cross reference This application claims the benefit of U.S. Provisional Patent Application No. 63 / 330,752, filed April 13, 2022, which is incorporated by reference herein in its entirety.
[0002] Incorporation by Reference All publications, patents, and patent applications mentioned in this specification are herein incorporated by reference to the same extent as if each individual publication, patent, or patent application was specifically and individually indicated to be incorporated by reference. To the extent that the publications and patents or patent applications incorporated by reference conflict with the disclosure contained herein, the present specification is intended to supersede and / or take precedence over any such conflicting material. [Background technology]
[0003] background Hyaluronic acid (HA) plays an important role in cellular and extracellular matrix (ECM) homeostasis in the skin. HA is involved in regulating hydration, cell turnover, metabolism, tissue repair, nutrient exchange, and protection against free radical damage. HA-bound water in both the dermis and epidermis is important for skin hydration. Although HA decreases with aging, the HA content in skin actually remains constant with age. The difference is that HA becomes increasingly tissue-bound and more resistant to extraction. This HA encapsulated within tissue proteins may be limited in its hydration capacity, and the lower molecular weight (MW) HA present in these tissue-bound forms may be pro-inflammatory. Thus, topical compositions that accelerate the synthesis of high MW HA would be beneficial to improve skin health.
[0004] Elastin is an important extracellular matrix (ECM) protein that provides stretch, resilience, elasticity, and elasticity to tissues and organs, including skin. Normal levels of elastic fiber production, organization, and integration with other skin extracellular matrix proteins, proteoglycans, and glycosaminoglycans are key to maintaining healthy skin structure, function, and youthful appearance. Elastin production decreases with age, and elastin degrades upon exposure to environmental insults, especially sun exposure, causing loss of skin structural integrity and contributing to sagging or crepiness of the skin and associated undesirable changes in appearance. Disruption of the elastic fiber network also leads to suboptimal wound healing and impaired structure and appearance of scars and stretch marks. Thus, topical compositions that can enhance the production of elastic fibers would be highly advantageous to improve and / or restore the appearance, texture, elasticity, and wound healing capacity of skin. Summary of the Invention
[0005] overview Skin aging is associated with loss of skin moisture and reduced barrier function.Aged or damaged skin may show various signs of inflammation, which may be visible as certain skin conditions, including but not limited to increased skin redness, increased visibility of fine blood vessels, and rosacea.Environmental influences, such as excessive UV exposure, may contribute to the progressive visible changes seen in aged skin.Topical compositions and methods that promote the inherent high MW HA production in skin or increase elastin production may be useful for treating various skin conditions.
[0006] In many cases, improving skin hydration and reducing inflammation in the skin can help treat damaged, inflamed, or aging skin. Application of topical compositions containing peptides has been used to treat damaged, inflamed, or aging skin.
[0007] Described herein are compositions and methods that include topical formulations and applications of octapeptides. In some embodiments, the compositions and methods described herein reduce skin inflammation, the appearance of solar elastosis, and / or signs of skin aging. In some embodiments, the compositions and methods described herein improve skin health, appearance, and hydration. In some embodiments, the compositions and methods described herein increase HA production and / or increase elastin production.
[0008] There remains a need to promote proper skin hydration and healthy skin tone, texture and elasticity in individuals.Skin aging is associated with loss of skin moisture, and dry skin leads to reduced barrier function, as well as reduced elastin production and degradation of elastin fiber network.Environmental influences such as excessive UV exposure also contribute to the visible progressive changes seen in aging skin, such as accelerated development of fine lines and wrinkles, and reduced skin elasticity.There is a need for topical compositions and methods that promote the production of inherent high MW HA in epidermal and dermal cells to improve skin health, and promote elastin production to restore or improve the appearance of aged or damaged skin.

[0085] Detailed Description Skin aging is associated with the loss of skin moisture and the reduction of barrier function.Aged or damaged skin may show various signs of inflammation, which may be visible as specific skin conditions, including but not limited to increased skin redness, increased visibility of fine blood vessels, and rosacea.Environmental influences, such as excessive exposure to ultraviolet light, may contribute to the progressive changes seen in aged skin.
[0086] In many cases, improving skin hydration and reducing inflammation in the skin can help treat damaged, inflamed, or aging skin. Application of topical compositions containing peptides has been used to treat damaged, inflamed, or aging skin.
[0087] Described herein are compositions and methods comprising topical formulations and applications of the octapeptide. In some embodiments, the compositions and methods described herein reduce skin inflammation, the appearance of solar elastosis, and / or signs of skin aging. In some embodiments, the compositions and methods described herein improve skin health, appearance, and hydration. In some embodiments, a composition comprising the octapeptide results in increased synthesis of high MW HA compared to skin not treated with the composition. In some embodiments, the octapeptide in the composition stimulates synthesis of high MW HA. In some embodiments, the composition increases elastin production.
[0088] As described herein, a group of active agents was identified that stimulated high MW HA production in both epidermal and dermal cell types. Members of one class of these active agents (e.g., octapeptides) contain amino acid sequence features present in both collagen and elastin. Upon application of a topical formulation containing octapeptides, endogenous signaling pathways may recognize these short peptide sequences that mimic extracellular matrix (ECM) degradation products and upregulate the innate response to produce high MW HA. These novel approaches to skin treatment described herein, including high MW HA+peptide topical application, aim to increase the production of exclusively high MW HA in both epidermal and dermal cells. These formulations of compositions and methods of using them were created to maximize hydration capacity in both the epidermis and dermis while promoting regenerative activity within the ECM. Application of the octapeptide formulation resulted in a quantifiable increase in skin hydration, a concomitant reduction in redness, inflammation, and the appearance of fine lines and wrinkles, as well as a notable reversal of solar elastosis ECM structure to a healthier, denser ECM network.
[0089] In some embodiments, the composition comprising an octapeptide increases the production of elastin in the skin. In some embodiments, the composition comprises octapeptide-45, tripeptide-1, and hexapeptide-12. In some embodiments, the composition upregulates expression of genes associated with ECM regulation in the skin. In some embodiments, the composition increases MFAP4 expression.

[0147] Stability testing Stability testing of compositions can be performed as follows: High temperature testing is now commonly used as a predictor of long term stability. High temperature testing can be performed at 37°C (98°F) and 45°C (113°F). If the product is stored at 45°C for 3 months (and shows acceptable stability), it should be stable at room temperature for 2 years. A good controlled temperature is 4°C (39°F), with most products showing excellent stability. In some cases, the product is subjected to -10°C (14°F) for 3 months.
[0148] In some cases, the stability of the product is evaluated by undergoing three cycles of temperature testing from -10°C (14°F) to 25°C (77°F). In such cases, the product is placed at -10°C for 24 hours, then placed at room temperature (25°C) for 24 hours. This completes one cycle. An even more stringent test is a five cycle test from -10°C to 45°C, which places a great deal of stress on the emulsion.
[0149] In some cases, the dispersed phase (of an oil-in-water emulsion) may separate and rise to the top of the emulsion, forming a layer of oil droplets. This phenomenon is called creaming. Creaming is one of the first signs of approaching emulsion instability. In some cases, one test method to predict creaming is centrifugation. In some cases, the emulsion is heated to 50° C. (122° F.) and centrifuged at 3000 rpm for 30 minutes. In some cases, the emulsion is examined for signs of creaming.
[0150] In some embodiments, the formulation and packaging may be sensitive to UV light. In some cases, the product is placed in a glass and the actual packaging is placed in a light box with broad spectrum output. In some cases, a separate glass bottle completely covered in aluminum foil acts as a control. In some cases, discoloration of the product may be observed.
[0151] For all the above tests, color, odor / scent, viscosity, pH value, and, if available, particle size uniformity and / or particle agglomeration under a microscope may be observed.

[0207] Figure 2A shows data for HAS2 in keratinocytes treated with various compounds. Data is presented as fold change in gene expression compared to untreated cells.
[0208] Figure 2B shows data for hyaluronidase 2 (HYAL2), a HA reductase, in keratinocytes treated with various compounds. Hexapeptide-11 showed a strong upregulation of HAS2 in keratinocytes and a strong downregulation of HYAL2 in keratinocytes (Figure 2A-B). Octapeptide showed a moderate downregulation of HYAL2 in keratinocytes. Data are presented as fold change in gene expression compared to untreated cells.
[0209] FIG. 3 shows data on early growth response 3 (EGR3) in keratinocytes treated with various compounds. HEX11 induced a significant upregulation of EGR3 by approximately 7-fold. EGR3 is a late epidermal regulator of differentiation highly expressed in the granular layer that may function to regulate the expression of skin barrier genes and strengthen the skin barrier. Data are presented as fold change in gene expression compared to untreated cells.
[0210] This example demonstrates that the peptides described herein are involved in regulating gene expression of genes involved in hyaluronic acid stimulation, hyaluronic acid turnover and maintenance, and the integrity and strength of the epidermal skin barrier.
[0211] Example 2. Selection of agents for in vitro HA production and size assessment Provided herein is an example of how octapeptide, SymDecanox™, Tremella, lactoferrin, phosphatidylserine, Hylasome™, Aquaxyl™, and the complete formulation stimulate secretion of high molecular weight (high MW) hyaluronic acid (HA) from dermal fibroblasts (and keratinocytes). Provided herein is an assay for HA synthesis.
[0212] Agents identified by RNA-seq as novel HA production stimulators in fibroblasts were used together with other active agents previously determined to stimulate HA production to confirm the production of HA by fibroblasts and to determine the molecular weight (MW) / size of the HA produced. The components selected and treatment concentrations used are listed in Table 1. The rationale for the selection of these agents is described here.
[0213] Selection of agents for in vitro HA production and size assessment. Generally, the octapeptide (a unique peptide) upregulates hyaluronan synthase-2 (HAS2) gene expression in fibroblasts (based on the RNA-Seq data described in Example 1).
[0214] Lactoferrin may provide wound healing attributes, promote fibroblast proliferation, and increase HA secretion.
[0215] Syn-Hycan is a synthetic tripeptide that stimulates HA. Published evidence shows that the synthetic trifluoroacetate tripeptide tetradecylaminobutyroylvalylaminobutyric acid urea restores facial skin volume by stimulating HA synthesis. Syn-Hycan increases HA and CD44 in skin in vitro and ex vivo.
[0216] Phosphatidylserine stimulates hyaluronan synthesis. Sodium hyaluronate crosspolymer (Hyalasome) is an extremely high MW synthetic HA with exceptionally high water binding capacity resulting in excellent moisturizing properties.
[0217] Tremella fuciformis extract is derived from an edible mushroom and may provide high levels of moisture as a natural HA stimulator and has antioxidant properties.
[0218] Hydroxymethoxyphenyldecanone is an HA booster, antioxidant, and anti-irritant, which can stimulate dermal and epidermal hyaluronic acid levels by 259% and 198%, respectively, versus placebo in an ex vivo human skin model.
[0219] Hexapeptide-11 can upregulate HAS2 and downregulate the HA reductase hyaluronidase 2 (HYAL2) in keratinocytes (based on the RNA-seq data in Example 1).
[0220] Table 1. Compounds used to treat fibroblasts for HA production assessment by PAGE TIFF2025512393000002.tif69159
[0221] In vitro HA production and size assessment Dermal fibroblasts were cultured in growth medium to near confluence in 6-well plates. When they reached confluence, the growth medium was replaced with serum-free medium for 24 hours. The cells were then treated with the compounds shown in Table 1. After 72 hours, 100 μl of medium was collected from each treatment condition. The medium was concentrated in a SpeedVac concentrator to a final volume of approximately 10 μl. All 10 μl from each condition was loaded onto an acrylamide gel (NuPAGE 4-12% Bis-Tris protein gel, Invitrogen, Waltham, MA). Sodium hyaluronate, research grade, (HA2M) from Lifecore Biomedical (Chaska, MN) was reconstituted as recommended by the manufacturer and served as a MW reference representing high MW HA. The gel was run at 200 V for 3 hours to separate MW sizes from proteins and ECM components isolated from the supernatant with the HA2M reference as a comparator. To avoid overheating, the gel buffer was replaced with fresh room temperature buffer every 20 min. Gels were stained using Stains-All (Millipore Sigma, Burlington, MA) and destained according to the manufacturer's protocol. Bands migrating at the same size as the HA2M band indicated production of high MW HA.
[0222] Data showing the effect of several compounds on hyaluronic acid production in human dermal fibroblasts after 72 hours of treatment can be seen in Figure 4. Numbers 1-10 are the names of the compounds listed above in Table 1. Number 11 is the concentrated supernatant of untreated cells. Number 12 is the HA2M control (2 MDa / high MW HA) shown as a reference point. Figure 4 demonstrates that the fibroblasts produce HA in the range of 2 MDa / high MW HA, none of which produce low molecular weight (LMW) HA.
[0223] Verifying HA Fibroblasts were cultured as described above to near confluence in 6-well plates. The cells were then treated with compounds shown in Table 1. After 72 hours, 100 μl of medium was collected from each treatment condition. The medium was then subjected to hyaluronidase enzyme treatment (1 mg / ml) for 2 hours at 37° C. One condition was left undigested (100 μg / ml of the octapeptide). Samples were run on an SDS-PAGE gel, stained, and destained as described above. The results are shown in FIG. 5. Lanes 1-8 correspond to treatments using sample numbers 1-8 listed in Table 1. Lane 9 corresponds to the octapeptide treatment at 100 μg / ml that was left undigested. Lane 10 is the HA2M control (2 MDa / high MW HA) shown as a reference point. The absence of a band after digestion indicated that the band identified in the previous step was HA with a high molecular weight (of about 2 MDa).
[0224] The octapeptide stimulates high MW HA in a dose-responsive manner in dermal fibroblasts. Human dermal fibroblasts were treated with the octapeptide (1x and 10x, corresponding to 100 μg / ml and 1000 μg / ml, respectively) or left untreated. After 72 hours, supernatants were collected, concentrated, run on SDS-PAGE, stained and imaged. Experiments were performed in quadruplicate and the density of bands from each supernatant was quantified (in arbitrary units (AU)) using ImageJ. Data are graphed in FIG. 6 and represent the mean ± standard deviation of band density for each treatment condition. The large increase in signal density in the 10x octapeptide treatment indicated a dose-responsive increase in the production of high MW HA in dermal fibroblasts.
[0225] Example 3. Multicenter evaluation of topical hyaluronic acid and octapeptide formulations on facial skin This example includes a study on the progressive effectiveness of treatment using a topical HA and octapeptide formulation as part of a facial skin care routine in a third experiment. The formulations tested included topical application of normal skin care using a composition containing high MW HA and octapeptide, SPF 30+, optional ultra-light moisturizer after 4 weeks, and a gentle cleanser in the third experiment. This study evaluated the efficacy and safety of a composition containing high MW HA and octapeptide on facial skin. Photographic and histological analysis of biopsies using a treatment formulation, a composition containing high MW HA and octapeptide, SPF 30+, optional topical application of ultra-light moisturizer after 4 weeks also constituted an aspect of the third experiment.
[0226] Materials and Methods This open-label clinical trial was conducted over a 4-month period from November 2021 to March 2022 and was approved by the Institutional Review Board, Advarra, Inc. (Columbia, MD). Eligible participants were healthy men and women aged 25 to 70 years who did not have any clinically significant unstable medical conditions, were willing to use only topical test products, and refrain from prolonged sun exposure, topical treatments, and procedures during the course of study participation. Exclusions for study participation included previous hypersensitivity or known allergy to any of the ingredients in the test products, use of retinol or topical agents containing active substances within 30 days, injectable toxins or resurfacing procedures within 3 months, injectable fillers and oral isotretinoin within 6 months. In addition, participants who were pregnant, breastfeeding, and planning to become pregnant during the study period were excluded.
[0227] Eligible enrolled participants were given a topical serum to apply twice daily and returned to the office for follow-up visits at weeks 2, 4, and 8. All participants were provided with a gentle cleanser for AM and PM use, as well as SPF30+ for AM use. At each visit, participants cleansed their facial skin and allowed it to acclimate for 15 minutes before assessment, photography, and measurements. Participants then applied the topical serum and allowed it to acclimate for 15 minutes before a second set of assessments, photography, and measurements.
[0228] Skin Hydration Sensor Measurements. At each visit, participants took three measurements on the right and left sides of the face using a skin hydration sensor measurement system by Wearifi (Chicago, IL). 15 minutes after cleansing the facial skin and 15 minutes after applying a topical test product. Measurements were performed in the same area at each visit. The measurement depth of the sensor was optimized to 50 μm to capture the water content across the stratum corneum and upper epidermis. The measurements are a quantitative result of the volumetric ratio of water in skin tissue, which represents an absolute value with a direct relationship to effective hydration.
[0229] Participant Assessment and Satisfaction. At all follow-up visits, 15 minutes after cleansing the skin, participants completed an assessment of their facial skin with the topical test product compared to baseline (using a 5-point scale) and overall satisfaction (using a 7-point scale). At each visit, 15 minutes after applying the topical serum, participants completed an assessment of their facial skin (using a 5-point scale).
[0230] Investigator Assessment. At baseline and week 8, the investigator completed a facial skin assessment 15 minutes after cleansing. A 10-point scale was used to assess fine lines / wrinkles, fine lines, texture, erythema, dryness, and moisture / hydration. Scale: 0 absent, 1-3 mild, 4-6 moderate, 7-9 severe.
[0231] Photography. At each visit, photographs were taken 15 minutes after cleansing the skin and after application of the test products. There were three different camera systems used in this study: VISIA® Skin Analysis System, (Canfield Scientific, Inc., Parsippany, NJ), LifeViz® Infinity and LifeViz® Micro (Quantificare, Inc. US, Cumming, GA).
[0232] Biopsies. 3 mm punch biopsies were performed around the ear at baseline and at weeks 2, 4, and 8 after application. Participants selected for biopsy were instructed to apply the topical serum around the ear twice daily for the duration of the study. An independent dermatopathologist evaluated the tissues before and after application of the study product.
[0233] Histology. Biopsies were fixed and sectioned for histological analysis according to standard protocols. Sectioned biopsies were mounted on slides and stained with hematoxylin and eosin to reveal epidermal and dermal cellular structures, including structures of the dermal ECM. Sectioned biopsies were mounted on slides and labeled for CD44 protein expression using anti-CD44 antibodies via immunohistochemistry according to standard protocols. CD44 labeling is shown in sections in a darker brown stain.
[0234] result An independent statistician completed the analyses using descriptive statistics, parametric and non-parametric tests.
[0235] The average hydration level in cleansed skin increases progressively with continued treatment. Analyses were completed for clean skin between baseline and follow-up visits, and between clean skin and after application of the test product at each visit. Pairwise comparisons between each time point were also calculated. 15 minutes after cleansing facial skin: At each follow-up visit, there was an increase in hydration measurements compared to baseline. At weeks 4 and 8, there was a statistically significant increase in hydration compared to baseline and the previous visit (Figure 7).
[0236] At each visit, hydration measurements were statistically significantly higher as measured post-application compared to clean skin (Figure 8). At 4 and 8 weeks post-application, measurements were also significantly higher than baseline and post-application measurements at week 2.
[0237] Compilation of participant ratings and satisfaction after cleansing and application At weeks 2, 4, and 8, 15 minutes after cleansing the skin, participants who gave a favorable rating of either strongly agree or agree were statistically significantly greater compared to week 2 for the following ratings (Figure 9):
[0238] Fifteen minutes after application of the test product at all visits, the percentage of participants who rated favorably continued to increase with each visit (Figure 10).
[0239] As can be seen in Figure 11, participants' overall satisfaction was rated favorably on a scale of 4-6 and increased statistically significant: 90.0% at week 2, 97.8% at week 4, and 97.9% at week 8 (p=.0061).
[0240] Results of the investigator's evaluation The mean investigator assessment scores were compared across five categories of features related to facial skin health and appearance (Figure 12). Compared to baseline, all assessment grades were statistically significant at the 8 week mark, p<.0001. Grades for reduction in fine lines / wrinkles, reduction in fine lines, texture, erythema, and dryness, and increase in moisture / hydration.
[0241] The mean investigator assessment scores were compared across the study at baseline and 8 weeks after initiation of treatment. As demonstrated in Figure 13, there was a wide range of increases in the mean assessment of facial skin moisture / hydration.
[0242] Photos and Analysis: Treatment with HA Immerse Serum (high MW HA + octapeptide) formulation, SPF 30+, and optional Ultra Light Moisturizer after 4 weeks. Figures 14-21 are photographs, analyses, and tissue sections from subjects at baseline as part of the third experiment and at various time points after initiation of treatment with usual skin care using a composition comprising high MW HA and an octapeptide, SPF 30+, optional ultra-light moisturizer after 4 weeks, and a gentle cleanser.
[0243] FIG. 14A demonstrates improved appearance and reduced redness after 4 weeks in a female subject, age 39.
[0244] FIG. 14B shows the results of a VISIA® Skin Analysis System for the subject from FIG. 17A demonstrating a quantifiable reduction in erythema.
[0245] Figure 15 shows photographs taken at baseline, week 2, week 4, and week 8 (from left to right) to demonstrate the progressive effect of skin improvement in a female subject, age 35. When comparing each time point, visible progressive changes are evident improving the appearance of fine lines, skin texture, and redness, indicating that continued treatment provides progressively enhanced results.
[0246] Figures 16A-16C demonstrate the degree of improvement in quantifiable features of appearance in the subject from Figure 15 comparing baseline and week 8 measurements. Figure 16B shows the results of a VISIA® Skin Analysis System to show a measurable reduction in red areas on the face. Figure 16C quantifies the effect of treatment using the VISIA® Skin Analysis System to result in a reduction in the total extent of pore size on the subject's face.
[0247] Figures 16D-16E demonstrate the extent of reduction in the appearance of fine lines and wrinkles after 8 weeks of treatment. The reduction in the appearance of fine lines and wrinkles in the skin around the eyes is particularly noticeable. Figure 16E quantifies the effect of treatment using the VISIA® Skin Analysis System to result in a reduction in the visibility of fine lines and wrinkles on the subject's face.
[0248] Figures 17A-17B show photographs and analysis at baseline and 8 weeks post-treatment to demonstrate improvements to the appearance of skin texture in a female subject, age 38. Figure 17B quantifies the effect of treatment using the VISIA® Skin Analysis System to result in an improvement in the appearance of skin texture on the subject's face.
[0249] 18A-18C show photographs demonstrating the efficacy of treatment to show a significant reduction in the appearance of erythema and rosacea in a male subject, age 48.
[0250] FIG. 18A shows the progressive effect of treatment when comparing baseline to weeks 2, 4, and 8 in reducing visible redness in a male subject, age 48.
[0251] Figures 18B-18C show close-up views to demonstrate the degree of visible reduction in erythema and rosacea in both the left and right cheek areas in the subject from Figure 18A at week 8. The reduction in visibility of fine blood vessels after this treatment period is particularly evident.
[0252] 19A-19C show the progressive effect of reducing the visibility of deep wrinkles near the mouth, fine lines across the face, and reducing the appearance of fine skin lines resulting in the appearance of smoother, firmer skin when comparing baseline, week 2, week 4, and week 8 in a female subject, age 73.
[0253] Figures 20A-20C show tissue analysis within periauricular biopsies of three subjects at baseline and 8 weeks after treatment with a composition containing HA Immerse Serum (high MW HA + octapeptide). Figures 20A-20C show hematoxylin and eosin stained sections from biopsies from the same subjects compared at baseline and 8 weeks, respectively (3 subjects analyzed in total). The extent of dermal solar elastosis, visible as old, thin collagen fibers in the ECM, is evident in each baseline sample. After 8 weeks of use of HA Immerse, the old, thin collagen fibers in the dermis were replaced with thicker, healthier collagen fibers, producing a much denser, healthier dermis and ECM. This dramatic reversal of the cellular, extracellular, and structural features of solar elastosis was an unexpected and significant finding after only 8 weeks of treatment in all three subjects analyzed. The extent of recycling of old ECM and its replacement with denser, healthier ECM indicates the therapeutic benefit of treatment in both the superficial and deeper regions of the dermis.
[0254] Figures 21A-21C show histological analysis of CD44 staining within periauricular biopsies of two subjects at baseline and 8 weeks after treatment with HA Immerse Serum (high MW HA + octapeptide). Figure 21A shows a section from the first subject with CD44 expression labeled in brown via immunohistochemistry. As CD44 is a receptor for HA and has been shown to be upregulated upon increased extracellular HA, the increase in CD44 labeling in both the epidermis and dermis at 8 weeks indicates increased stimulation and secretion of HA. Figures 21B-21C show a section from the second subject with CD44 expression labeled in brown via immunohistochemistry. Similarly, the increase in CD44 expression at 8 weeks indicates increased stimulation and secretion of HA. Increased CD44 expression is seen throughout the epidermis and dermis.
[0255] Figure 22 shows the chemical structure of Octapeptide-45, which comprises the amino acid sequence Gly-Pro-His-Gly-Val-Arg-Glu-Ala. Octapeptide-45 is an octapeptide contained in the formulation of HA Immerse Serum.

[0259] Example 5. Gene Expression Studies for Compositions Containing TriHex+Octapeptide method Human adult dermal fibroblast cell lines were cultured in medium from ZenBio (Durham, NC) in 48-well plates at 37 °C in 5% CO 2The cells were maintained at 37°C in an incubator. After 48 hours, the cells were treated with the compounds listed in Table 4 below. One group was left untreated for comparison purposes. After 24 hours, the cell medium was removed and the cells were washed once with PBS. The cells were lysed and generated using 100 μl of RNA lysis buffer ("10x RNA lysis buffer", Takara Bio, Catalog No. 635013) and diluted 1x in an RNAse-free microcentrifuge tube. RNA extraction, library construction, and sequencing were then performed on 25M paired-end 100bp reads per sample. Differentially expressed genes were identified and pathway enrichment was assessed using the Reactome Pathway database.
[0260] Table 4. Compositions for in vivo gene expression testing TIFF2025512393000005.tif33166
[0261] result As shown in Figure 23A-D, the combination of TriHex + Octapeptide-45 showed gene expression synergism for S100A2, LAMA3, MERTK, and ITGB4 genes. S100A2 is S100 calcium-binding protein A2. It is a secreted matrisome-associated protein expressed in the dermis. S100A2 activates protein phosphatase 5 (PP5) in a calcium-dependent manner. PP5 is a serine / threonine phosphatase involved in oxidative stress response. LAMA3 is laminin, alpha 3. LAMA3 is the gene encoding the alpha 3 chain of laminin 5, which is the main link between the epidermal basal cells and the papillary dermis. It initiates hemidesmosome formation and provides stable attachment of the epidermis to the dermis. Laminin 5 may also accelerate the assembly of the basement membrane and enhance the repair of damaged skin. MERTK is a tyrosine-protein kinase MER. MERTK transmits signals from the extracellular matrix to the cytoplasm by binding to several ligands, including LGALS3, TUB, TULP1, or GAS6. After activation by ligands, MERTK plays a role in various processes such as macrophage clearance of apoptotic cells, platelet aggregation, cytoskeletal rearrangements, and engulfment. ITGB4 is integrin beta 4. Partnered with integrin alpha 6, ITGB4 is a receptor for laminin. The α6β4 integrin protein is particularly important in strengthening and stabilizing the skin, as it is a component of hemidesmosomes in the epidermis.
[0262] Table 5 lists several pathways related to ECM regulation whose gene expression is upregulated by Octapeptide-45 or the combination of TriHex+Octapeptide-45, indicating therapeutic benefit in ECM regulation, including elastin synthesis. The p-values are the results of over-representation analysis. Over-representation analysis is a statistical (hypergeometric distribution) test that determines whether a particular Reactome pathway is over-represented (enriched) in the data. This test produces a probability score, which is corrected for false discovery rate using the Benjamani-Hochberg method.

[0264] Example 6. Ex vivo testing of MFAP4 and tropoelastin (TE) expression on skin samples treated with TriHex + octapeptide method With reference to FIG. 24, human skin tissue was degreased, cut into pieces with a diameter of approximately 7 mm, and cultured in cell culture medium (1.88 μM CaCl 2 The tissue samples were placed in a transwell insert with DMEM / F12 containing 2% fetal bovine serum, 50 μM adenine, 0.02 nM triiodothyronine, 1% ITS-X (insulin, transferrin, selenium mix), 1% glutagro (glutamine equivalent), 1% pen / strep, and 1% gentamicin. The medium was changed daily. The human skin tissue samples were equilibrated for 3 days and then treated with the compounds listed in Table 6 once a day for 7 days. After 7 days of treatment, the skin samples were fixed in formalin and embedded in paraffin according to industry standard procedures. The resulting blocks were prepared and sectioned for immunofluorescence staining.
[0265] Antibodies directed against tropoelastin (TE) (available from Elastin, Owensville, MO) and against microfibril associated protein 4 (MFAP4) (available from ThermoFisher Waltham, MA) were used to detect new elastin production in treated cells. Appropriate fluorescent secondary antibodies were used for detection by fluorescence microscopy. Images were acquired and analyzed using ImageJ software.
[0266] Data were obtained from a minimum of three donor skin samples, with replicates or triplicates performed for each compound treated.
[0267] Table 6. Compositions for ex vivo testing TIFF2025512393000007.tif33166
[0268] result Microfibril-associated protein 4 (MFAP4) is an extracellular glycoprotein found in elastic fibers. MFAP4 is a ligand for microfibrils and tropoelastin that actively promotes tropoelastin (TE) self-assembly and is involved in proper elastic fiber organization. See P. Bartosz et al., 291 J. Biol. Chem. 1103-14 (Jan. 2016) (Figure 10) (reproduced as Figure 25).
[0269] Figure 27 shows images of immunofluorescence staining of cells with an antibody directed against MFAP4. MFAP4 expression is increased with TriHex (second from left), octapeptide-45 (second from right), and TriHex + octapeptide-45 treatment (right). The increase in MFAP4 expression with TriHex + octapeptide-45 indicates greater infiltration of new fibrils into the papillary dermis (see Figure 26) than that observed after treatment with TriHex and octapeptide-45 alone. Expression of MFAP4 indicates an opportunity for the formation of new elastin fibers.
[0270] Figure 28 is an image of immunofluorescence staining of cells with an antibody directed against TE. TE expression is increased with TriHex, Octapeptide-45, and TriHex + Octapeptide-45. The increase in TE production with TriHex + Octapeptide-45 indicates greater infiltration of new elastin fibers into the papillary dermis than that observed after treatment with TriHex and Octapeptide-45 alone. In addition, fiber alignment is more organized with the combined treatment, indicating that the newly formed elastin fibers are more stable.
