Skin aging reflects overall body aging and can indicate internal health conditions.

In this review, the authors explored how various hormones, particularly IGF-1, GH, estrogens, retinoids, and melatonin, influence human skin aging, highlighting potential new avenues for anti-aging therapies beyond the currently utilized topical retinoids and estrogens.

This article discusses the structure of the human type II 5 alpha-reductase gene and reports no new experimental results.

This study reports that K7 expression patterns observed in mice are similar to those in humans, revealing previously unreported expression in the gastrointestinal tract, tongue, and various "hard" epithelial tissues.

This study reports that variation in the ovine TCHH gene may influence wool fibre curvature, with specific gene variants affecting the mean fibre curvature in sheep.

This study identified a novel homozygous mutation in the 5'-UTR of the POMC gene, suggesting a new molecular mechanism for the syndrome of adrenal insufficiency, obesity, and red hair.

This review explores the mechanisms of adult stem cell self-renewal, using skin as a model, and reports no new results but raises important unanswered questions in the field.

This article reviews factors influencing hair aging and available treatments like minoxidil and finasteride for androgenetic alopecia but reports no new clinical results.
