This research found that melatonin plays a protective and modulatory role in skin biology, reducing UV damage and chemotherapy-induced hair follicle cell harm in human organ culture models.

This study found that Wnt signaling regulates the symmetric division of adult neural stem cells, increasing their numbers during subependymal regeneration, stroke response, and colony formation.

This study found that skin microbiota, particularly in wild-type mice, promotes wound-induced hair follicle neogenesis and wound healing, highlighting the potential downsides of routine antibiotic use on skin regeneration.

This review evaluated the evidence on skin disorders linked to levodopa treatment for Parkinson's disease, suggesting a possible association with melanoma, though evidence remains inconclusive and further studies are needed.

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.

This symposium reported that DNA damage accumulation in aging stem cells affects genome integrity, highlighting novel mechanisms like Bmi1's role in DNA repair and the involvement of BATF in lymphoid differentiation.

This article reviews the potential advantages of secretome derivatives from human uterine cervical stem cells in MSC therapy and notes the need for regulatory standards to ensure safety and efficacy.

This review discusses the role of stem cell progeny as integral components of stem cell niches, offering feedback that may influence different stem cell systems' microenvironments, but it presents no new research findings.

This study suggests that 5α-reduced glucocorticoids may have anti-inflammatory potential and could serve as biomarkers for liver inflammation in metabolic disease, with implications for drug development.

This study identified four circRNAs with significantly different expression levels in Liaoning cashmere goats, suggesting a potential role in regulating cashmere fineness.

This study found that subchronic finasteride treatment in male rats altered neuroactive steroid levels and steroid receptor expression in the brain, with some changes persisting after drug withdrawal.

This study reveals that somatosensory neurons in mouse skin exhibit structural plasticity during hair-follicle regeneration, which may temporarily impair the reliability of encoding gentle touch.

This study found that altering neonatal neurosteroid levels affected anxiety and aversive learning in adult rats, possibly through changes in hippocampal GABAergic functions.

This study suggests that inhibitors of steroidogenic enzymes may have therapeutic potential for certain behavioral disorders linked to dopaminergic hyperfunction, despite concerns about their endocrine impacts.

In this study, researchers identified genetic variants in the PCCA and PRLR genes that are significantly associated with hair coat length in Brangus heifers, potentially contributing to more thermotolerant cattle.

This laboratory study found that nonanal, a plant scent compound, may stimulate growth factors and cell proliferation in human hair follicle dermal papilla cells, suggesting a cAMP-mediated mechanism.

This study developed a new human hair research model combining 3D spheroid dermal papilla fibroblasts with plucked anagen hair shafts, potentially improving the evaluation of hair follicle differentiation.

This study identified genes potentially involved in hair and cashmere growth in the Laiwu black goat, highlighting specific gene expression differences between hair-growing and hairless skin.

This review identifies natural plants that possess androgen-related compounds, highlighting the potential of phytoandrogens as alternatives to allopathic treatments for conditions like hypogonadism, impotence, infertility, and erectile dysfunction.

This animal study found that finasteride, a 5-alpha reductase type 2 inhibitor, decreased dihydrotestosterone levels and c-Fos protein activation in the rat brain, but these effects may diminish after discontinuing the drug.

This review discusses the role of neurosteroids and androgens throughout different life stages, noting the potential disruptions caused by 5α-reductase inhibitors like finasteride, but no new clinical results are reported.

This review discusses the expanding understanding of TRPV3's role in pain and skin pathology, while highlighting the need for further pharmacological research to fully resolve its functions.

This research found that androgen bioactivity plays a role in normal female sexual differentiation, suggesting females develop within a significant androgenic environment, with implications for understanding conditions like congenital adrenal hyperplasia.
