In this review, researchers discussed recent insights into caspases, enzymes initially associated with cell death and inflammation, revealing their broader roles in cell proliferation, migration, and differentiation, and highlighting the importance of caspase knock-out mice for understanding their implications in diseases.

In this study, researchers analyzed spaceflight data from various sources and found that skin issues during spaceflight are linked to DNA damage, mitochondrial dysregulation, and gene alterations, while also highlighting the skin's adaptability post-flight.

This review discusses studies on hair growth and protein synthesis in hair follicles, highlighting the differing responses of mohair and cashmere goat follicles to signaling molecules, biotin, and amino acids, but contains no new results.

This study identified distinct gene expression programs in keratinocytes responsible for forming hard scales and soft interscale epidermis in chickens, revealing conserved differentiation genes similar to those in human skin.

This study developed a method to culture and maintain chicken feather follicles in vitro, preserving structure and biology similar to their in vivo state, though some gene expression was altered.

Terbinafine can cause hair loss.

This review summarizes the bioactive compounds and pharmacological functions of Cynomorium songaricum Rupr., emphasizing its potential in developing health-related products, and notes that further research is needed.

The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.

This study found that rhamnose can restore hair-inducing gene expression in dermal papilla cells and accelerate hair follicle regeneration by promoting the hair cycle into the anagen phase, suggesting its potential therapeutic application for alopecia treatment.

This review discusses the cornification process of epidermal keratinocytes in forming the skin barrier and reports no new results; it emphasizes the importance for diagnosis and treatment of skin disorders.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This study found that knock-down of keratin 15 in various cell lines affected cell spreading, morphology, migration, differentiation, and proliferation, suggesting its role in maintaining the stem cell nature of keratinocytes.

Cyclosporin doesn't stop hair loss.

In this study, FCE 28260 showed greater potency than finasteride in inhibiting 5α-reductase enzymes and reducing prostate DHT levels in rats.

In this study, finasteride altered the expression of nine proteins in the rat nucleus accumbens, suggesting new therapeutic targets and mechanisms for its effects on neuropsychiatric conditions.

This study reported that the compound (1R, 2S)-4-(2-cyano-cyclohexyl-oxy)-2-trifluoromethyl-benzonitrile effectively stimulated hair growth in mice and reduced sebum production in hamsters.

This study found that hydroxycinnamate derivatives, especially a compound named 10a, effectively inhibited SRD5A1 activity and protein expression in cell assays, suggesting potential for treating androgen-related conditions.

This chapter reviews hyperadrenocorticism in ferrets, covering its causes, symptoms, diagnosis, and treatment options, but reports no new research findings.

In this study, a 7-year-old male ferret was diagnosed with hyperadrenocorticism complicated by dilatative cardiomyopathy, chronic active hepatitis, and renal disease, following symptoms including progressive hair loss and severe dehydration.

This study found that black cohosh extract BNO 1055 reduced testosterone-induced prostate and seminal vesicle growth in rats, suggesting it may contain potent 5α-reductase inhibitors useful for prostate cancer prevention.

This study suggests that caribine may enhance the interaction between CRFR and maltose binding protein, potentially offering a new approach for treating hair loss.

This study synthesized and evaluated hydroxycinnamate derivatives for their ability to inhibit human SRD5A1, finding that three compounds showed significant inhibitory activity and low cytotoxicity. Compound 10a notably reduced SRD5A1 protein expression in cells, suggesting potential for nonsteroidal treatment of androgen-related conditions.

This article reviews the potential for α-difluoromethylornithine to help control hair growth and prevent cancer, but it does not present new clinical results.

This study found that tildacerfont treatment in males with congenital adrenal hyperplasia reduced androgen levels and improved markers of testicular function, suggesting potential benefits for male reproductive health.

This study found that among the tested analogs, compound 4e was the most effective in inhibiting wax esters in vivo in the Golden Syrian hamster ear model.

This study found that deslorelin implants can effectively reduce estradiol levels and support hair regrowth in neutered ferrets with hyperoestrogenism caused by nodular hyperplasia of the adrenocortex.

Formononetin, found in red clover, may treat hair loss with fewer side effects.

This study found that the Abyssinian and Sphynx breeds have significantly higher felinine:creatinine ratios in their urine compared to several longhaired cat breeds, suggesting hair growth may influence felinine production.

Finasteride helps reduce pain and inflammation in animals.

This study established a stable cell line for CRF1 receptor screening, which can be used to develop functional cosmetics and modulators potentially affecting hair re-growth.
