In this study, testosterone increased the expression of epithelial sodium channel proteins and mRNAs in rat kidneys, suggesting a potential mechanism for its effect on blood pressure through enhanced sodium reabsorption.

This review discusses the potential of follicular drug delivery systems to target the pilosebaceous unit and reports no new research findings.

This study suggests that high proliferative activity and peripheral invasion are key indicators of malignancy in canine sebaceous gland tumours. It also reports a higher incidence of circumanal gland and testicular tumours, indicating a possible androgen-related pathway in tumour development.

This review discusses the causes, diagnosis, and treatment of pediatric alopecia, emphasizing early diagnosis and considering holistic approaches, but reports no new clinical results.

This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.

This study observed that, in mouse ear epidermal stem cells, a cell-autonomous size control mechanism involving the RB pathway dictates S phase entry timing based on cell size, despite external environmental variations affecting growth rates.

This study found that activating Wnt/beta-catenin signaling in hair follicles is sufficient to induce adipocyte generation in the dermis, affecting both hair follicle stem cell activation and adipocyte differentiation.

In this study, researchers found that crude extracts from Avicennia marina and its component avicequinone C inhibit mechanisms contributing to androgenic alopecia in vitro, including 5α-reductase activity and DHT-AR interactions, potentially promoting hair growth and delaying the catagen phase in human dermal papilla cells.

This review discusses the conserved molecular mechanisms controlling hair follicle development and cycling and suggests they may also apply to other ectodermal derivatives, like teeth and feathers, but it reports no new results.

This research found that feather pattern formation in birds is regulated by a mechanochemical system involving fibroblast growth factor and bone morphogenetic protein signaling, which is altered in the flightless emu and ostrich.

In this study, human dermal fibroblasts were identified as natural host cells that support productive Merkel cell polyomavirus infection, and the MEK antagonist trametinib was introduced as an effective inhibitor to control the virus.

This review explores the biology of wool follicles and suggests their potential use as research models in modern biology, but it reports no new findings.

This review explores the role of Foxn1 in mammalian skin biology, discussing its influence on hair follicle function and the potential for further research to enhance understanding of epithelial differentiation.

This review examines beta-catenin's role in stem cell renewal, lineage selection, and tumor formation in the epidermis and reports no new experimental findings.

This study suggests that wounding skin in adult mice can trigger new hair follicle formation, indicating mammalian skin may have greater regenerative capacity than previously thought.

This study identified five mutations in the gene LSS in individuals with unexplained hypotrichosis simplex, highlighting a potential role of mislocalized LSS proteins in disrupting hair follicle biology.

In this study, researchers observed that hyperandrogenic PCOS patients exhibited distinct miRNA and TGFβ signaling gene expression patterns in granulosa cells, suggesting these factors may play a role in PCOS pathogenesis.

This paper discusses mechanisms by which various chemicals disrupt male sexual differentiation, concluding that mixture risk assessments should include a broader set of compounds beyond phthalates to address cumulative reproductive health risks.

This study discovered a novel interaction between the vitamin D receptor and LEF1, essential for normal Wnt signaling in keratinocytes, which is crucial for regular hair cycling.

This review discusses the challenges in selecting optical parameters for photobiomodulation studies on hair regrowth and wound healing, reporting no new clinical results and recommending more rigorous, standardized research approaches.

This study demonstrated that topical oleuropein induced hair growth in mice by activating the Wnt10b/β-catenin signaling pathway and increasing expression of several growth-related genes in skin tissue.

Acne is significantly influenced by genetics, and understanding its genetic basis could lead to better, targeted treatments.

This study found that the transcription factor Gata6 plays a crucial role in adult mouse hair follicle regeneration by promoting the renewal and preventing DNA damage of rapidly proliferating progenitor cells.

This study suggests that icariin promotes hair follicle growth in mice by enhancing IGF-1 expression in dermal papilla cells.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

This study found that proteins secreted by early-passage dermal papilla cells, including SDF1, MMP3, biglycan, and LTBP1, may play significant roles in hair follicle regeneration.

This study found that both ethanol and aqueous extracts of Lepidium sativum seeds improved insulin signaling and reduced obesity-related metabolic changes in high-fat diet-fed rats, suggesting potential as a dietary supplement.

This review examines the role of stem cells and their niches in continuously growing ectodermal organs like teeth, hair, and claws, providing insights from mouse models without presenting new research findings.

This study suggests that synthetic ceramides may promote hair growth by inducing proliferation of human dermal papilla cells through modulation of Wnt/β-catenin and BMP2/4 signaling pathways.

This study observed that the OCIAD2 and DCN genes in Liaoning cashmere goats have opposite effects on hair growth by interacting with the TGF-β signaling pathway, influencing follicle morphogenesis and periodic changes.
