Balanced protease activity is crucial for healthy skin and hair development.

In this study, Caizhixuan hair tonic was found to promote hair growth in androgenetic alopecia mice by regulating the PI3K/Akt and apoptosis pathways.

This study found that D-peptide crosslinked MAP hydrogel accelerated material degradation in vivo but significantly enhanced skin regeneration, suggesting an adaptive immune response can drive regenerative healing even with rapid scaffold breakdown.

This study found that the hydrophilic PTK-UR foam with EG7 repeats significantly improved wound healing in porcine skin wounds compared to other scaffolds, suggesting potential for synthetic biomaterial applications.

This study suggests that epithelial-derived pop-up keratinocytes (ePUKs) may improve regenerative medicine applications due to their specific phenotype and increased expression of proteins involved in regulating cellular movement and wound healing.

This study reports that BMP2 expression in goat skin is higher during late telogen and early anagen phases, indicating a potential role in hair follicle regeneration.

This in silico study identified potential natural product compounds targeting a non-androgen pathway for promoting hair growth, but further laboratory validation is necessary before any clinical claims can be made.

TAT-GILZ peptide promotes hair growth by boosting stem cell activity.

This study demonstrated that fibrin hydrogels support skin-derived precursors in hair follicle neogenesis in mice, with new hair growth and regeneration of blood vessels and sebaceous glands observed.

This study found that isozyme profiles in polyoma virus-induced tumors were consistent and distinctive for each tumor type, except for salivary and mammary tumors which shared a profile.

The researchers reported that thymosin beta 4 promotes hair growth in various rat and mice models by influencing follicle stem cell growth, migration, and differentiation.

This study found that human hair keratin scaffold material implanted in damaged rabbit muscle tissue degrades via the ubiquitin system and is further processed by macrophagocytes and lysosomes.

This study demonstrated that treating platelet-rich plasma with ozone or procaine in vitro led to distinct changes in platelet activity, significantly enhancing the release of platelet-derived factors without damaging the platelets, indicating potential for improved regenerative therapies.

This article discusses the FDA's decision not to approve 5α-reductase inhibitors for prostate cancer prevention, citing an increase in high-grade tumors but no mortality evidence, and reports no new results.

This study found that the proprietary aptamer TAGX-0003 significantly inhibited IFNγ-induced effects in pre-clinical human models of alopecia areata, promoting hair regrowth and potentially preventing disease relapse.

In this preclinical study, researchers found that combining equal ratios of high molecular weight keratin intermediate filaments and low molecular weight keratin-associated proteins from human hair led to the most extensive fibrinogen precipitation, suggesting potential for developing effective hair protein-based hemostatic materials.

This study found that honokiol inhibits enzymes related to testosterone degradation in vitro, suggesting its potential as a lead compound for developing antiaging bioactive ingredients for men.

This article reviews the development of selective androgen receptor modulators and myostatin inhibitors as performance-enhancing drugs, highlighting ongoing challenges in achieving truly tissue-selective anabolic agents and reporting no new experimental findings.

This study provided the first proteome dataset for alopecia areata, revealing novel pathways in the disease mechanisms that may lead to new therapeutic targets.

This review discusses the shedding phase of the hair cycle, known as exogen, and reports no new findings while analyzing related processes like club fiber formation and release.

In this study, researchers found that serum Myostatin levels and HOMA-IR were significantly higher in patients with androgenic alopecia compared to controls, suggesting they could be indicators of disease susceptibility and severity.

In this study, PP-PTKL exhibited antioxidant, anti-inflammatory, and pro-melanogenic effects in laboratory settings, suggesting its potential role in preventing or treating hair greying. Further animal and human studies are needed to verify these findings.

In this study, researchers developed a promising transdermal agent using Triton X-100-modified polyethyleneimine that successfully delivered genetic material to hair follicle cells in mice, potentially alleviating hair loss due to androgenetic alopecia by promoting cell proliferation and inhibiting apoptosis.

This review discusses the structural and functional aspects of β-thymosin in invertebrates and reports no new experimental findings.

This source provides procedural details without reporting new experimental findings or conclusions.

This study found that in patients with androgenetic alopecia, cardiac troponin I levels positively correlated with age and certain heart functions, indicating possible cardiac involvement in the disease's progression.

This study suggests that polyamines regulate CK2 enzyme activity and its subcellular distribution, as demonstrated in mouse models and cell cultures with elevated levels of ornithine decarboxylase.

This study suggests 5α‐androstan‐3α‐17β‐diol may be the true inducer of kidney enzymes in certain mice, while its induction mechanism likely involves pinocytosis rather than a receptor protein.

Male hormones control a specific gene in hamster skin, with different hormones having varying effects.
