This study found that root hair growth is influenced by a complex interplay of auxin, inorganic phosphate, and transcription factors RSL2/RSL4, with reactive oxygen species playing a key role in this regulation.

This study explored how root hairs integrate opposing growth signals but did not report new conclusive findings on the activation of known molecular players in polar growth.

This study observed that downregulation of laminin-511 plays an important role in hair regression during the catagen stage in mice.

This study presents the first report on cloning and characterizing the full-length cDNA of SRD5A1 in Indian catfish (Clarias magur), revealing expression differences across reproductive phases and increased expression post-Ovatide administration in ovaries and testis.

In this study, photodynamic therapy significantly reduced inflammatory acne lesions and sebum secretion, possibly by inducing apoptosis in sebaceous glands and down-regulating TLR-2 and TLR-4 expression.

This study found that brain-derived neurotrophic factor (BDNF) inhibited hair shaft elongation and induced premature catagen development in cultured human hair follicles, partially through transforming growth factor β2.

This study found that Fgf20 signaling facilitates fibroblast migration and influences dermal condensate cell development during hair follicle morphogenesis by supporting cellular activities such as cell cycle exit and specific cell shape adoption.

This review discusses immunohistological and immunofluorescent methods for studying the human hair follicle cell cycle, reporting no new results, and suggests its potential for advancing cell cycle research.

This study found that male and female chicken feather morphology and color patterns can be extrinsically modified through molting and resetting the stem cell niche during regeneration.

In this study, combining endoscopic forehead lifting with hairline lowering successfully rejuvenated the upper facial area in 194 patients by lowering hairlines by an average of 18 mm and raising eyebrows by 5 mm, without serious complications.

In this mouse study, researchers found that dermal Wnt signaling/β-catenin activity is essential for fibroblast proliferation and initiating hair follicle formation by interacting with epidermal Wnt ligands.

In this study, T3 and T4 were found to directly influence human hair follicles in vitro, enhancing keratinocyte proliferation, prolonging the hair growth phase, and affecting pigmentation.

This study found that human hair follicles express erythropoietin and its receptor, suggesting these follicles may use erythropoietin signaling to modulate apoptosis under stress conditions like hypoxia and chemotherapy.

This study demonstrates that inhibiting SFRP1 with the antagonist WAY-316606 enhances hair growth in human scalp hair follicles ex vivo by facilitating Wnt signalling.

This guide reviews the biology of sebaceous glands and their evaluation methods, emphasizing their roles beyond lipid production in skin health and disease, and reports no new research results.

This study found that placental growth factor (PlGF) enhanced hair shaft elongation and accelerated hair follicle growth, suggesting its potential as a therapeutic target for alopecia.

This review updates the protective effects and molecular mechanisms of melatonin against ultraviolet-induced damage in human skin, reporting no new clinical findings.

This study found that foot shock stress prolonged the telogen stage and delayed anagen induction in the hair cycle of non-depilated mice, potentially through stress-induced actions of substance P.

This review discusses methods for evaluating hair growth-promoting effects of candidate substances for androgenetic alopecia, focusing on cell assays, organ cultures, and animal models, and reports no new results.

This study observed that while X-ray radiation did not alter major hair keratin composition in mice, it decreased hair follicle stem cell markers and increased Krt5, suggesting potential as a radiation biomarker.

This study suggests that Thyroxine (T4) may promote key features of human skin wound healing, such as re-epithelialization and angiogenesis, in an ex vivo model.

This study found that overexpression of Gsdma3 in mice led to epidermal hyperplasia, skin inflammation, and hair growth defects, suggesting gain-of-function mutations in Gsdma3 cause these conditions.

This study found that elevated expression of the protein Zyxin in hair follicles is associated with androgenetic alopecia and suggests it may be targeted for therapy.

In this study, the elimination of NG2+ hair follicle stem cells during the anagen phase was associated with an aggravated sensitization phase of allergic contact dermatitis, suggesting their immunosuppressive role.

This study found that inhibiting mineralocorticoid receptor signaling in female human hair follicles may promote hair growth by extending the anagen phase and encouraging keratinocyte proliferation.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This research reports that the polyG fragment within the Hoxc13 protein alters its gene regulatory functions, which could have influenced mammalian hair evolution by affecting pathways related to hair follicle development.

A specific hair protein variant increases the spread of breast cancer and is linked to worse survival rates.

This review discusses the molecular role of the vitamin D receptor in regulating various biological actions such as bone mineralization and reports no new clinical results, highlighting the complexity of vitamin D's function in multiple tissues.
