Abstract
Description
Title of the invention: BIOACTIVE NUT PEPTIDES FOR TREATING HAIR LOSS SCOPE OF DISCLOSURE
[0001] This disclosure relates to bioactive nut peptides and methods for treating and preventing hair loss, and for treating skin conditions of the scalp. CONTEXT
[0002] Hair follicles, particularly in humans, are complex structures with distinct components, each composed of various specialized cells. In addition to the cells responsible for hair production and anchoring, most hair follicles also contain sebaceous glands, which produce sebum. Some follicles have apocrine glands, which are found in specific areas such as the armpit. The structures within a hair follicle include the follicular papilla (FP) and the germinal epithelium (GE), collectively referred to as the bulb.The PF consists of mesenchymal cells and connective tissue, while the epithelial components include at least eight distinct cell lineages: the outer epithelial sheath (ORS), the companion layer (CL), the inner epithelial sheath Henle layer (He), the Huxley layer (Hu), the inner epithelial sheath cuticle (Csth), the capillary stem cuticle (Csft), the capillary stem cortex, and the stem medulla (Med).
[0003] In humans, scalp hair and hair in certain other areas grows in follicular units. A typical follicular unit on the scalp consists of two to four terminal hair follicles, one or rarely two vellus follicles, along with their associated sebaceous glands, a neurovascular plexus, an arrector pili muscle, and a circumferential band of adventitia collagen called the "perifolliculum."
[0004] Hair follicles are thought to produce approximately 20 individual hair shafts throughout their lifetime, going through phases of growth, shedding, involution, and regrowth. Although hair growth and follicular regeneration have been studied in mouse models, there are important differences between the biology of human and mouse hair follicles. In mice, a thick fur coat is vital for thermoregulation and other functions, with the follicles primarily producing terminal hairs (fur). In contrast, human skin has areas covered with hair follicles that produce vellus hair, which is less visible. The hair follicles of Mice have synchronous growth cycles early in life, but these become less synchronized with age, while human hair follicles progress asynchronously through their growth cycles. On an adult human scalp, approximately 80 to 90% of follicles are in the anagen (growth) phase, 10 to 20% in the telogen (resting) phase, and 1 to 2% in the catagen (regression) phase.
[0005] Dermal papilla cells (DPCs) in hair follicles are crucial for hair growth, residing in the hair bulb and regulating the hair follicle growth cycle. Their ability to induce hair follicle formation, known as inductivity, is essential for both preventing hair loss and promoting hair growth. DPCs secrete growth factors and signaling molecules that interact with epithelial cells in the hair follicle, driving cell proliferation and differentiation. This interaction is essential for initiating and sustaining hair growth, as DPCs play a key role in the cyclical phases of hair growth: anagen (growth), catagen (regression), and telogen (resting). DPC activity influences the transitions between these phases, affecting hair length and thickness.
[0006] The transition from telogen to anagen is complex and involves several molecular signals, including Wnt and bone morphogenetic protein (BMP) signaling pathways. During telogen, Wnt signaling is inactive in the hair follicle. The transition to anagen is triggered by signals from CPDs, which activate Wnt signaling in epithelial stem cells located in the follicle bulge region. This activation promotes the proliferation and differentiation of these stem cells, leading to the formation of a new hair shaft and downward growth of the follicle into the dermis. In contrast, BMP signaling generally inhibits hair growth. High BMP signaling during telogen helps maintain the follicle in its resting state.For anagen to begin, PMO signaling must be reduced, often involving inhibitory molecules that block PMO pathways and allow Wnt signaling to prevail, thus initiating hair growth.
[0007] Furthermore, hypoxia (low oxygen levels) has been shown to enhance CPD inductivity in 2D models and promote angiogenesis, which is vital for the healthy development of hair follicles and the scalp. A proper balance between these signaling pathways is essential for efficient hair follicle development and cycling. Recent studies have also observed an increase in autophagy at the onset of anagen in the natural hair cycle, and it has been found that activating autophagy in aged mice prevented (or slowed) hair loss. DISCLOSURE SUMMARY
[0008] This disclosure relates to bioactive walnut peptides and the use of walnut peptides for topical application to the scalp for use in the treatment or prevention (or slowing) of hair loss, and the treatment of scalp conditions. The inventors have made a surprising discovery that bioactive walnut peptides positively influence physiological pathways associated with hair growth and hair follicle health, and downregulate physiological pathways detrimental to healthy hair growth and scalp function. For example, bioactive walnut peptides stimulate or activate dermal papilla cells while downregulating genes associated with cell cycle arrest and IL-1 (interleukin-1) signaling, which is associated with inflammation, the immune response, and apoptosis.
[0009] Walnuts are one of the most widespread and oldest nuts in the world. They have high nutritional value and are rich in oleic acid, linoleic acid, alpha-linolenic acid, and other unsaturated fatty acids, vitamins, and proteins. Walnuts are commonly used to make walnut oil because they have a high lipid content. The residue remaining after lipid extraction is considered a by-product, although it contains nut proteins and other useful components. Walnut protein is mainly composed of albumin, globulin, gliadin, and glutenin.
[0010] Bioactive nut peptides can be derived from nut proteins or can be synthesized. For example, nut peptides are obtained by enzymatic hydrolysis, fermentation hydrolysis, or chemical hydrolysis of nut proteins or produced synthetically, for example, by solid-phase synthesis. Bioactive peptides that are particularly useful according to the present disclosure typically have a molecular weight of less than 6,000 Da and often less than 1,000 Da. These nut peptides may have from 2 to 50 amino acid residues, but typically have from 2 or 3 amino acid residues to about 20 amino acid residues.
[0011] Preferably, bioactive walnut peptides have a minimum of 2 or 3 amino acid residues up to about 20 amino acid residues and confer a positive physiological or dermatological effect on the scalp, hair follicles, or both. Bioactive peptides include amino acids joined by covalent bonds, also called amide or peptide bonds, while proteins are polypeptides of higher molecular weight (MW), i.e., having more than 50 amino acid residues. Bioactive walnut peptides exhibit They typically have hormonal or drug-like activities and are classified according to their mode of action.

[0048] X-Thr-Trp-Leu-Pro-Leu-Pro-Arg-Z (I)
[0049] X-Tyr-Val-Leu-Leu-Pro-Ser-Pro-Lys-Z (II),
[0050] in which,

[0053] Bioactive nut peptides can be obtained by hydrolyzing nut proteins into small molecular peptides with molecular weights between the molecular weights of individual amino acids and the molecular weights of proteins. This can be achieved using biological or chemical processes. For example, bioactive peptides can be prepared by enzymatic procedures, fermentation, and chemical processes.
[0054] Bioactive nut peptides can be synthesized by coupling the carboxyl group or C-terminus of one amino acid to the amino group or N-terminus of another. Due to the possibility of unforeseen reactions, protecting groups are sometimes required. The chemical synthesis of peptides begins at the C-terminus of the peptide and ends at the N-terminus. Peptides can be synthesized either by solid-phase peptide synthesis, liquid-phase peptide synthesis, or by condensation of fragments. In principle, the seemingly simple formation of a peptide bond can be accomplished using any of the procedures available in organic chemistry for the synthesis of carboxylic acid amides.
[0055] The general process of solid-phase peptide synthesis (e.g., of a resin) begins with the attachment of the first amino acid, the C-terminal residue, to the resin. To prevent polymerization of the amino acid, the alpha-amino group and the reactive side chains are protected by a temporary protecting group. Once the amino acid is fixed to the resin, the resin is filtered and washed to remove excess byproducts and reagents. Next, the N-alpha protecting group is removed in a deprotection process, and the resin is washed again to remove excess byproducts and reagents. Then, the next amino acid is coupled to the fixed amino acid. This is followed by another washing procedure, which leaves the resin-peptide assembly ready for the next coupling cycle. The cycle is repeated until the peptide sequence is complete. Then, typically, all protecting groups are removed, the peptide resin is washed, and the peptide is cleaved from the resin.
[0056] Enzymatic hydrolysis involves the use of commercial enzymes to obtain bioactive peptides. The enzymes are responsible for cleaving the peptide bonds established in the protein, thereby releasing the encrypted peptide. For the enzyme to exert its activity, it is important that the enzyme binds to the substrate and proceeds with enzymatic catalysis. The enzyme possesses specific active sites containing residues that form temporary bonds with the substrate and residues that catalyze the reaction with the substrate. In this way, binding sites and catalytic sites are formed, respectively. The bonds forming the enzyme-substrate complex are usually hydrogen bonds, hydrophobic interactions, or Van der Waals interactions.Enzymatic hydrolysis can generally be carried out in three ways: (i) under traditional batch conditions; (ii) using immobilized enzymes; or (iii) using ultrafiltration membranes. Many proteolytic enzymes are known and include those described, for example, in Cruz-Casas et al., Enzymatic Hydrolysis and Microbial Fermentation: The Most Favorable Biotechnological Methods for the Release of Bioactive Peptides (Food Chem (Oxf). 3:100047, Dec. 30, 2021).
[0057] Microbial fermentation is a biotechnological process used to obtain bioactive peptides. This process involves the use of microorganisms capable of producing proteolytic enzymes, with the aim of having these enzymes hydrolyze proteins into shorter peptides. The microorganisms generally used are bacteria, fungi, or yeasts, which may be present in the substrate natively or added as a starter culture. The microbial fermentation process can be divided into several systems. However, immersion fermentation and solid-state fermentation are the most widely used.
[0058] Immersion fermentation uses a culture of microorganisms in a liquid medium containing nutrients. This system is suitable for microorganisms with high water-level activity, such as bacteria, and offers the advantage that the generated bioactive peptides are easy to purify. Solid-state fermentation uses microbial growth on nutrient-rich solid substrates. It features the advantage of releasing nutrients in a controlled manner and is suitable for fungi and microorganisms with lower moisture requirements.

Optional exclusions
[0098] Bioactive nut peptides may be derived from nut proteins or may be synthesized. For example, nut peptides are obtained by enzymatic hydrolysis, fermentation hydrolysis, or chemical hydrolysis of nut proteins or produced synthetically, for example, by solid-phase synthesis. In various embodiments, one or more bioactive nut peptides are isolated from other constituents of the nut and walnut tree from which the bioactive nut peptide is derived. Nuts and walnut trees include constituents such as fats, proteins, fibers, vitamins, minerals, phytosterols, etc. The term "walnut tree" in the context of this disclosure includes all parts of the walnut tree, such as the roots, trunk, bark, branches, leaves, hulls, and shells.Consequently, the one or more nut peptides useful in the processes and compositions disclosed herein may be isolated from other constituents of the walnut or walnut tree. For example, the one or more nut peptides may be free or substantially free of nut fats, nut peptides and proteins (other than the one or more specified bioactive nut peptides), nut fibers, and the like. Another pharmaceutical or cosmetic composition comprising one or more nut peptides may be free or substantially free of nut fats, nut peptides and proteins (other than the one or more specified bioactive nut peptides), nut fibers, and the like.
[0099] Nuts, particularly their shells, are useful for producing a variety of dye compounds. The principal dye compounds of walnuts and walnut trees are juglone and tannins. Therefore, one or more bioactive nut peptides can be isolated from the dye compounds of walnuts and walnut trees, including juglone and tannins. Similarly, pharmaceutical or cosmetic compositions comprising one or more bioactive nut peptides are preferably free or substantially free of dye compounds from walnuts and walnut trees.For example, in various embodiments, the pharmaceutical or cosmetic composition does not comprise any tincture compound derived from walnuts and nuts or comprises less than 1% by weight, preferably less than 0.1% by weight, more preferably less than 0.01% by weight, more preferably less than 0.001% by weight, even more preferably less than 0.0001% by weight, and even more preferably less than 0.00001% by weight, relative to the total weight of the pharmaceutical or cosmetic composition.
[0100] In a preferred embodiment, bioactive walnut peptides are isolated from juglone, a compound naturally occurring mainly in the shells and leaves of walnut trees, particularly black walnut (Juglans nigra). Juglone is a type of naphthoquinone. The bioactive walnut peptides are preferably isolated Nut naphthoquinones, including juglone.

[0102] In a preferred embodiment, the bioactive walnut peptides are isolated from tannins. Tannins are polyphenolic compounds found in many plants and are known for their astringent properties. In walnuts, tannins are mainly present in the skin or shell of the fruit. These compounds contribute to the bitter taste of walnut skins and have antioxidant and antimicrobial properties. Although they are more concentrated in the shell and leaf of the walnut, some tannins are also present in the edible part of the walnut, albeit in smaller quantities. In a preferred embodiment, the pharmaceutical or cosmetic composition comprising one or more bioactive walnut peptides is free or substantially free of tannins.For example, in various embodiments, the pharmaceutical or cosmetic composition does not include nut tannins or includes less than 1% by weight, preferably less than 0.1% by weight, more preferably less than 0.01% by weight, more preferably less than 0.001% by weight, even more preferably less than 0.0001% by weight, and even more preferably less than 0.00001% by weight, relative to the total weight of the pharmaceutical or cosmetic composition.

Preferably, the pharmaceutical or cosmetic composition includes less than 0.01% by weight, more preferably less than 0.001% by weight, even more preferably less than 0.0001% by weight, and even more preferably less than 0.00001% by weight of peptide(III), relative to the total weight of the pharmaceutical or cosmetic composition. Processing methods
[0106] As already mentioned, bioactive nut peptides are particularly useful for topical application to the scalp in processes for treating or preventing hair loss, and for treating scalp conditions. More specifically, bioactive nut peptides are useful in processes for increasing hair density, increasing follicular density, increasing hair shaft thickness, increasing hair length, preventing hair loss, reducing hair loss, or any combination thereof, or, for example, in an individual who needs it. The processes include applying an effective amount of one or more bioactive nut peptides to the scalp of an individual, preferably an individual who needs it.In another embodiment, the individual in need is an individual with one or more disorders chosen from among alopecia grand, androgenic alopecia, alopecia areata, alopecia universalis, involutional alopecia, trichotillomania, telogen effluvium, anagen effluvium, cicatricial alopecia, alopecia with scarring, scalp thinning, hair shaft abnormalities, infectious hair disorders, genetic disorders, and hair loss due to chemotherapy, hormonal imbalance, fungal infection, medication use, chemical hair treatment, or aging.
[0107] In a preferred embodiment, bioactive nut peptides are useful in processes for treating alopecia in an individual who needs them, wherein the individual who needs them is an individual suffering from adrenergic alopecia, telogen alopecia, patchy alopecia, traumatic alopecia, telogen effluvium, nutritional deficiencies, metabolic defects, marked weight loss, diabetes, hypervitaminosis, hypovitaminosis, zinc deficiency, alopecia vulgaris, pustular alopecia, erythrodermic alopecia, arthropathic alopecia, para-alopecia, palmoplantar pustulosis, ichthyoses, keratodermas and genodermatoses with pathological co-occurrence disorders. The processes include applying an effective amount of one or more bioactive nut peptides to the scalp of an individual who needs it.
[0108] In other embodiments, one or more bioactive nut peptides are useful in processes for stimulating or activating dermal papillary cells of the scalp and / or hair follicles, for potentiating fibroblast growth factor (FGF) and / or vascular endothelial growth factor (VEGF) in the scalp and / or hair follicles, for protecting or preserving hair follicles by regulating or managing oxidative stress (management of reactive oxygen species (ROS)) in the scalp and / or hair follicles, for downregulating cell cycle arrest and / or IL-1 (interleukin-1) signaling in hair follicles and / or scalp, for treating inflammation of hair follicles and / or scalp, or combinations thereof.
[0109] In a preferred embodiment, one or more bioactive nut peptides are useful in processes for treating scalp conditions. Non-limiting examples of scalp conditions include dandruff, scalp psoriasis, and acne.
[0110] For example, bioactive nut peptides are useful in processes for treating, preventing, or slowing hair loss. With regard to scalp conditions, bioactive nut peptides are particularly useful in processes for preventing and treating dandruff, scalp psoriasis, acne, or combinations thereof. Typically, one or more nut peptides are applied to the scalp in a pharmaceutical or cosmetic composition, which includes a physiologically acceptable carrier. Common and useful physiologically acceptable carriers include water, water-soluble solvents, and mixtures thereof.
[0111] It may be beneficial to use more than one (two or more) bioactive nut peptide in the processes and compositions described throughout the disclosure. Different bioactive nut peptides can act together to provide a variety of influences. beneficial to the scalp and hair. For example, one or more bioactive walnut peptides can treat hair loss by potentiating the secretion of growth factors and signaling molecules that interact with epithelial cells in the hair follicle, leading to cell proliferation and differentiation. One or more other bioactive walnut peptides can combat or prevent chemical changes or natural effects of aging that can shorten the hair growth phase (anagen phase), leading to thinner hair and ultimately hair loss. Due to their different mechanisms of action, two additional bioactive walnut peptides can be used together to synergistically treat, prevent (or slow) hair loss, and address scalp disorders.
[0112] In various embodiments, the use of two or more bioactive nut peptides is preferred. These two or more bioactive nut peptides may have similar activities or may offer different activities that treat or prevent hair loss and treat scalp conditions. In other embodiments, the use of three or more bioactive nut peptides is preferred. The use of multiple bioactive peptides allows for the modification of more than one physiological mechanism in skin treatment. Combinations of bioactive nut peptides can interact synergistically and provide benefits that exceed the sum of the individual contributions of the peptides. For example, the synergistic activity of a combination may be at least 5%, at least 10%, or at least 25% greater than the sum of the individual activities of the corresponding amounts of the bioactive nut peptides.
[0113] Various changes can be made to the compositions and processes described above without departing from the scope of the invention. Therefore, it is intended that any disclosure contained in the above description and in the examples given below shall be interpreted in an illustrative and not limiting manner. EXAMPLES Example 1
[0114] Inductivity of dermal papilla cells (DPCs)
[0115] Dermal papilla cell (DPC) inductivity refers to a state in which DPCs retain the ability to be stimulated or activated to promote hair follicle development. Growth factors, such as fibroblast growth factor (FGF) and vascular endothelial growth factor (VEGF), have been shown to stimulate DPCs and enhance their inductive properties, promoting hair growth (Ito et al., Decapeptide with fibroblast growth factor (FGF)-5 partial sequence inhibits hair growth suppressing activity ofFGF-5. J Cell Physio., 2003 Nov; 197(2):272-83).
[0116] Dermal papilla cells (DPCs) were cultured in a basal follicular dermal papilla cell medium (Promocell product number C-26501) supplemented with 4% fetal calf serum (FCS), 0.004 mL / mL bovine pituitary extract, 5 pg / mL insulin, and 1 nf / mL fibroblast growth factor (FGF). The dermal papilla cells were treated with bioactive walnut peptides for 24 hours using concentrations of 100 pM to 250 pM of each peptide. At the end of the culture period, RNA extraction and bulk RNA sequencing were performed. RNA was extracted from each sample according to standard protocols, quantified, and subjected to high-throughput RNA sequencing using DNA Nanoballs technology.
[0117] Bioinformatic analysis of transcriptomic data was performed using gene ontology-driven and gene panel-driven approaches (Examples 3 and 4). In the gene ontology (GO) terminology analysis, all significantly modulated genes were analyzed to see which predefined pathways they tend to enter (an unsupervised approach) (Example 3). In the gene panel approach, DP cell-specific marker genes were selected and separated into biological functions of interest. Then, a relative gene-panel score based on the integration of the p-value and the change factor was calculated for each gene panel relative to the negative control (a curative approach) (Example 4). Example 2 Autophagy inductance
[0118] The body requires a significant amount of energy for hair growth. During the active growth phase of hair follicles (anagen), metabolic demand is highest as hair cells divide and rapidly synthesize new proteins. Alpha-ketoglutarate (α-KG) is a key metabolite in cellular metabolism and plays an important role in autophagy, the process by which cells break down and recycle their own components. It has effects on cellular metabolism, oxidative stress, and signaling pathways, which are relevant to healthy hair growth. α-KG exhibits antioxidant properties that regulate oxidative stress in cells. Reducing oxidative stress can protect hair follicle cells from damage and promote their longevity and overall health.Furthermore, by managing reactive oxygen species (ROS), it helps prevent damage to hair follicle cells. Alpha-KG promotes hair growth through its roles in metabolism. Oxidative stress management, signaling pathways, and stem cell regulation. Its impact on these processes may contribute to healthier hair follicles and potentially improve hair growth.
[0119] Bioactive walnut peptides can be studied in mice, for example C57BL / 6 mice, or genetically modified strains exhibiting hair loss, with compositions containing one or more bioactive walnut peptides, such as the composition shown in Example 5. Various concentrations of one or more bioactive walnut peptides can be tested. Minoxidil, a vasodilator used to treat hair loss, can be used as a positive control (Messenger and Rundegren, Minoxidil: Mechanisms of Action on Hair Growth, Br. J. Dermatol. 150:186-194 (2004)).
[0120] Mice are divided into two groups: a treatment group and a control group. The treatment group receives one or two daily topical applications of the peptide compositions, while the control group receives a vehicle (placebo). The dorsal skin of the mice is shaved or plucked to facilitate observation of hair growth. The peptide compositions are applied once or twice daily for a specified period, for example, four or eight weeks. The mice are monitored throughout the treatment period for overall health and signs of hair growth. Changes in hair density, color, and texture are also noted.
[0121] At the end of the treatment period, the mice are euthanized in accordance with ethical guidelines, and skin samples are collected from both the treated and control areas for analysis. For histological and biochemical analysis, the collected skin samples are treated by impregnation with paraffin, sectioning, and staining for histological examination. Immunohistochemical or immunofluorescence techniques are used to detect autophagy markers, such as LC3 and p62, in the skin tissues. In addition, Western blotting of tissue extracts can be performed to quantify autophagy-related protein levels, and quantitative PCR can be used to assess autophagy-related gene expression.
[0122] Bioactive nut peptides can have their autophagy inductivity evaluated in mice as highlighted, for example, in Chai et al., Stimulation of Hair Growth by Small Molecules that Activate Autophagy, Cell Reports, 25:3143-3421 (2019) and Sun et al., Autophagy Induces Hair Follicle Stem Cell Activation and Hair Follicle Regeneration by Regulating Glycolysis, Cell and Bioscience, 14(6) (2024). Example 3 Gene ontology-driven analysis
[0123] Gene ontology-driven (GO) analysis is a method used in bioinformatics and computational biology to interpret and organize large sets of gene or protein data based on the gene ontology. It provides a structured and standardized mechanism for describing gene functions, processes, and cellular locations. To establish which biological processes, if any, are influenced by walnut peptide (I) (SEQ ID NO: 45), walnut peptide (II) (SEQ ID NO: 46), and walnut peptide (III) (SEQ ID NO: 47), an initial analysis of transcriptomic data was performed using GO-driven analysis, in which all genes that are significantly modulated are analyzed to see if they impact any predefined biological pathways. All genes that were statistically significantly upregulated or downregulated were analyzed for their association with biological processes.Multivariate results are presented as the ratio of differentially expressed genes in the dataset that match genes in public databases for any given biological process (rich ratio) and the significance of this association (Q value).
[0124] The literature-based panels used in the GO-driven analysis are shown below.

[0126] Nut peptide (I)
[0127] Walnut peptide (I) (SEQ ID NO: 45) was tested on PD cells at concentrations of 100 pM and 250 pM and was found to influence biological pathways involved in hair growth. In particular, walnut peptide (I) (SEQ ID NO: 45) showed significant upregulation of genes involved in hair follicle development, angiogenesis, and hypoxia. In addition, walnut peptide (I) (SEQ ID NO: 45) significantly downregulated genes associated with cell cycle arrest and IL-1 (interleukin-1) signaling, which is associated with inflammation, the immune response, and apoptosis. The data therefore suggest that walnut peptide (I) (SEQ ID NO: 45) has a positive influence on biological pathways that treat or prevent hair loss, while simultaneously downregulating biological pathways that are detrimental to hair growth.
[0128] Nut peptide (II)
[0129] Walnut (II) peptide (SEQ ID NO: 46) was tested on PD cells at concentrations of 100 pM and 250 pM and was found to influence biological pathways involved in hair growth. Walnut (II) peptide (SEQ ID NO: 46) was found to positively influence biological pathways associated with mitochondrial activity and adenosine triphosphate (ATP) production. Surprisingly, walnut (II) peptide (SEQ ID NO: 46) downregulated biological pathways that are detrimental to hair growth; for example, it downregulated inflammatory pathways.
[0130] Nut peptide (III)
[0131] Walnut Peptide (III) (SEQ ID NO: 47) was tested on PD cells at concentrations of 100 pM and 250 pM and was found not to influence biological pathways involved in hair growth. Unlike Walnut Peptide (I) and Walnut Peptide (II), Walnut Peptide (III) did not show any benefits associated with the treatment or prevention of hair loss.
[0132] In summary, for the genes that were downregulated by Walnut Peptide (I), the associated pathways were more diverse. In particular, cell cycle arrest, IL1 signaling, IL4 response, and apoptosis regulation were downregulated, suggesting that Walnut Peptide (I) reduces negative signals causing adverse effects on CPD activity, potentially creating a healthier microenvironment. With walnut peptide (II) (at both concentrations), a different set of pathways was associated with the upregulated genes. Most of these genes were associated with mitochondrial and ATP / energy production pathways. This suggests that walnut peptide (II) has a different mechanism of action than walnut peptide (I) and acts on CPD activation to provide the energy needed for rapid growth. For the genes that were downregulated by walnut peptide (II), the associated pathways were similar to those of walnut peptide (I), with a strong association with antigen presentation (which could trigger inflammation) and cell cycle arrest. Furthermore, the genes responsible for the downregulation of ATP production were also downregulated with walnut peptide (II).
[0133] With Walnut Peptide (III), very few significant associations were observed for both upregulated and downregulated genes. Genes associated with ATP production and the hypoxia response were observed with the lowest concentration of Walnut Peptide (III), but overall, the effects were smaller compared with Walnut Peptides (I) and (II). Example 4 Gene panel-driven analysis
[0134] In addition to the GO-driven analysis described above, a gene panel (GP)-driven analysis was performed. A GP-driven analysis is used like a GO-driven analysis in genomics and clinical research to investigate specific sets of genes related to particular diseases, conditions, or biological processes. However, the GP-driven approach involves analyzing a predefined panel of genes associated with a specific condition or trait of interest. This is a type of "curative" approach. Genes are selected based on their known or suspected association with specific conditions, their role in relevant biological pathways, or their potential impact on biological outcomes. Often, panels are customized for a specific research project or clinical need.
[0135] GP-driven analysis allows for targeted analysis using gene panels belonging to pathways of interest that may not be found in the public domain. CPD-specific genes (identified from published literature) were isolated to determine the precise transcriptomic changes in CPD. Importantly, a panel of genes relevant to CPD inductivity was evaluated, along with autophagy and hypoxia genes. The aggregate score of each gene (whether positive or negative) was used to determine an effect relative to the negative control. The unique panels used for the tests are shown below.
[0136] [Tables4] Unique Panels Inductivity Autophagy Hypoxie LRP4 ATG9A SLC2A1 RGS2 ULK1 VEGFA TRPS1 WIPI1 HIF1A WNT5A ULK2 CA9 ALPL BCL2 EGLN3 SEMA4C PINK1 BNIP3 NOG NBR1 NDO WDR45 RBP1 SQSTM1 MEF2C ATG16L1 SOX2 GABARAP SPRY4 ATG3 PM04 ATG14 BAMBI MAP1LC3B LEF1 GABARAPL1 ATG10 OPTN UVRAG
[0137] With Walnut Peptide (I), a relative increase in inductivity and hypoxia was readily observed, while autophagy and WNT signaling were observed to a lesser extent. These results are consistent with the gene ontology-based (GO) analysis (Example 3) while also providing further insight into other positive regulators of CPDs relevant to anagen entry. Surprisingly, a strong downregulation of PMO signaling was observed, which is known to act against WNT signaling. In the targeted analysis, Walnut Peptide (I) induces major positive signals and reduces negative signals for CPD activity compared to the negative control.
[0138] Walnut peptides (II) and (III) had no direct effect on genes relevant to CPD activity in the context of anagen entry. Therefore, no large increase in relative scores compared to the negative control was observed. The data are illustrated by a pie chart showing relative gene scores in [Fig. 1]. [Fig. 2] shows walnut peptide (I) (SEQ ID NO: 45) upregulating growth signals and the anagen phase of follicular hair growth. It also shows walnut peptide (II) promoting mitochondrial function and adenosine triphosphate production, thus helping to meet the energy requirements for active hair growth.

[0143] The terms "a," "an," "the," and "the" are understood to encompass both the plural and the singular. Thus, the phrase "one of their mixtures" also refers to "their mixtures." Throughout the disclosure, the phrase "one of their mixtures" is used, following a list of items as shown in the following example where the letters A through F represent the items: "one or more items selected from the group consisting of A, B, C, D, E, F, and one of their mixtures." The phrase "one of their mixtures" does not require that the mixture include all of the items A, B, C, D, E, and F (although all of the items A, B, C, D, E, and F may be included). Rather, it indicates that a mixture of two or more of A, B, C, D, E, and F may be included. In other words, it is equivalent to the formulation "one or more elements chosen from the group consisting of A, B, C, D, E, F, and a mixture of two or more of A, B, C, D, E and F".
[0144] Similarly, the expression "one of their / its salts" also refers to "their / its salts".

This list of counterions, however, is not exhaustive. The appropriate counterions for the components described herein are known in art. This disclosure may not expressly identify all compounds mentioned throughout that may exist as salts or in ionized form, for example, when formulated in a pharmaceutical or cosmetic composition. Nevertheless, to the extent that salt or ionized forms of the compound exist and are known, they are understood to be encompassed within the scope of this disclosure, even if not expressly mentioned. For example, many surfactants may exist as salts or in ionized form in pharmaceutical or cosmetic compositions.Similarly, peptides, including bioactive nut peptides, can be in salt or ionized form, which can improve their stability or compatibility. Non-limiting examples of beneficial compounds include sodium, potassium, calcium, magnesium, chloride, sulfate, phosphate, acetate, citrate, TFA (trifluoroacetate), bicarbonate, and nitrate. Throughout this disclosure, when referring to a bioactive nut peptide, salts of bioactive nut peptides are understood to be included. if terms such as "one of their salts" or "their salts" are not expressly associated with peptides or each time a peptide is mentioned.
[0146] The expression "one or more" means "at least one" and therefore includes individual components as well as mixtures / combinations.
[0147] The term “plurality” means “more than one” or “two or more”.
[0148] Except in operational examples, or unless otherwise indicated, all numbers Indications of quantities of ingredients and / or reaction conditions can be modified in all cases by the term "approximately," meaning within + / - 5% of the stated amount. For example, a quantity "approximately 10% by weight" can include quantities as low as 9.5% by weight and as high as 10.5% by weight. Similarly, a quantity "approximately 50% by weight" includes quantities as low as 47.5% by weight and as high as 52.5% by weight.
[0149] All percentages, parts and ratios here are based on weight unless otherwise stated.
[0150] Some of the various component categories mentioned throughout the disclosure may overlap. However, a single overlapping component cannot simultaneously serve as two different components despite the overlap. Some alcohols function both as a preservative and as a water-soluble solvent, which can be useful in a physiologically acceptable carrier. If an embodiment, claim, or other quotation throughout the disclosure communicates that both a preservative and a water-soluble solvent are present, necessary, or required, a single alcohol such as ethanol cannot simultaneously serve as both a preservative and a water-soluble solvent. In this case, the ethanol will serve as either a preservative or a water-soluble solvent, but simultaneously as both.
[0151] As used herein, all provided ranges are intended to include each specific range within the given ranges, as well as a combination of intermediate subranges. Thus, a range of 1 to 5 specifically includes 1, 2, 3, 4, and 5, as well as subranges such as 2 to 5, 3 to 5, 2 to 3, 2 to 4, 1 to 4, etc. All ranges and values disclosed herein are inclusive and combinable. For example, any value or point described herein that falls within a range described herein can serve as a minimum or maximum value for inferring a subrange, etc.
[0152] The term “substantially free” or “essentially free” as used here means that up to 2% by weight of the element may be present. In other embodiments, however, up to 1.5% by weight, up to 1% by weight, up to 0.5% by weight, up to 0.1% by weight, or up to 0.01% by weight of the element may be present. For example, in the case where a pharmaceutical or cosmetic composition is substantially free or essentially free of a component, The pharmaceutical or cosmetic composition may include up to 2% by weight of the component. However, the pharmaceutical or cosmetic composition preferably includes 1.5% by weight or less, 1% by weight or less, 0.5% by weight or less, 0.1% by weight or less, 0.01% by weight or less, or no amount of the specified component.
[0153] As used herein, a "subject" may be a human primate, a non-human primate, a mammal, a rat, a mouse, a cow, a horse, a pig, a sheep, a goat, a dog, a cat, and the like. "Mammal" includes humans and domestic animals such as laboratory animals (e.g., mice, rats, monkeys, dogs, etc.) and domestic animals (e.g., cats, dogs, pigs, cattle, sheep, goats, horses, rabbits) and non-domestic animals such as wildlife and the like.
[0154] All components that are presented positively throughout the disclosure may be excluded negatively from the claims, for example, a claimed composition may be "free", "essentially free" (or "substantially free") of one or more components that are presented positively in this disclosure.
