This study found that activin A signaling is crucial for hair follicle neogenesis in human dermal papilla 3D cultures combined with mouse epidermal cells.

This study demonstrates that Puerariae Lobatae Radix may regulate skin lipid metabolism by inhibiting sebaceous gland growth and reducing triglyceride secretion, highlighting its therapeutic potential for sebaceous gland-related conditions.

In this study, fenugreek seed extract showed significant androgenic and spermatogenic effects in male rats, likely through inhibiting testosterone metabolism, without impacting cardiovascular health.

This study identified that blocking the PTGDR2 receptor in human hair follicles in vitro and in mice reversed the hair growth inhibition caused by PGD2, suggesting a potential approach for treating alopecia.

This study found that among young women in West Bengal, India, co-occurring PCOS and related conditions like estrogen resistance and leptin receptor insufficiency are common, with notable genetic variations identified, including impairments in leptin signaling and insulin resistance.

This case study reports that a 3 ½ year-old male with vitamin D-dependent type II rickets showed partial improvement in alopecia and rickets when treated with high doses of 1,25(OH)2 vitamin D3.

This study found that inhibiting JAK signaling can unexpectedly trigger hair growth in resting-phase mouse skin, implicating JAK-STAT pathways and oncostatin M in maintaining hair follicle stem cell quiescence.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

This study provides a comprehensive platform to explore stem cell interactions regulating hair follicle growth, revealing key signaling pathways in epithelial-mesenchymal interactions using advanced RNA sequencing and transgenic reporters.

This study found that gypenosides from Gynostemma pentaphyllum increased procollagen synthesis in vitro and reduced periorbital wrinkles by about 14% in a clinical trial with 24 women.

This study found that vitamin D regulates cholesterol metabolism and may influence prostate cancer development through mechanisms affecting prostate cell growth and sex hormone metabolism.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This article reviews the role of epithelial-mesenchymal interactions in hair follicle morphogenesis and the hair cycle, suggesting potential paths for developing treatments for hair growth disorders but providing no new clinical findings.

This research discusses how epithelial stem cells in the skin maintain normal homeostasis, contribute to wound repair, and highlights the importance of these processes, as defects can lead to skin diseases including cancers, but provides no new experimental results.

This study found that RXRα/RARγ heterodimers are necessary for retinoic acid-induced keratinocyte proliferation in the skin, while normal epidermal maintenance does not require RAR-mediated signaling.

In this review, researchers explored the roles of vitamins A, B3, C, D, and E in skin immunity, highlighting their potential as therapeutics for skin diseases due to their antioxidant, anti-inflammatory, and antimicrobial properties.

This review discusses the role of the mineralocorticoid receptor in skin biology, highlighting its potential involvement in keratinocyte and hair physiology, and proposes it may affect the side effects of glucocorticoid use.

This review discusses the clinical characteristics, diagnosis, and treatment of alopecia areata, exploring potential environmental, immunological, and genetic factors involved in its development, but reports no new research findings.

This review discusses major advances in understanding inherited hair diseases through genetic research and reports no new clinical results; the authors emphasize the potential for new preventive and therapeutic tools.

This study in cashmere goats found that DNA methylation levels were lower during hair follicle differentiation compared to induction, suggesting it plays a critical role in gene regulation for hair morphogenesis.

This study found that 1,25 dihydroxyvitamin D3 significantly increased the expression and activity of vasculoprotective natriuretic peptide receptor-A in cultured inner medullary collecting duct cells, suggesting a potential mechanistic role in cardiovascular and renal benefits.

This study indicates that targeting the PTH/PTHrP receptor may potentially stimulate hair growth, particularly for chemotherapy-induced alopecia, as observed in hairless and cyclophosphamide-treated mice.

This review discusses the role of vitamin D metabolism in skin immunity and wound healing but does not present new results, highlighting the need for further research into its therapeutic applications.

This study examines how the Severity of Alopecia Tool score was used to assess Alopecia Areata in patients while excluding systemic conditions that might affect vitamin D levels, but reports no new clinical results.

This review summarizes how common polymorphisms in androgen and estrogen receptor genes may influence aging-related symptoms and diseases in men, but it reports no new clinical results.

This study found that iron deficiency anemia is a key factor in the development of telogen effluvium, and higher 25-hydroxyvitamin D3 levels in TE patients may be linked to increased UV exposure.

This study found that both topical calcipotriol and narrow band ultraviolet B phototherapy improved hair regrowth and vitamin D3 levels in alopecia areata patients.

This study suggests that ADAM 10 and 12 proteases may play important roles in the regulation of hair cycling through their expression patterns in hair follicle structures.

In this study, topical calcipotriol was found to be more effective than oral vitamin D for improving mild to moderate alopecia areata, with a 68% improvement rate and no correlation between serum vitamin D levels and treatment efficacy.

This review discusses the complex relationship between melasma and factors like female sex hormones, genetics, and ultraviolet light exposure, but reports no new clinical findings.
