This study found significantly higher P-Smad2 levels in both lesional and nonlesional skin of organ transplant recipients, suggesting elevated TGF-β signaling might contribute to their increased cancer susceptibility.

This study found that overexpressing Rps14 in supporting cells promoted hair cell regeneration in the organ of Corti by facilitating cell proliferation and differentiation.

This study found that the absence of Hif-p4h-2 in specific mouse skin cells disrupted hair follicle development, leading to hair loss due to irregular keratin formation and pathway signaling.

This review discusses the paradoxical effects of valproic acid on hair, noting that it can both cause alopecia and stimulate hair growth, but reports no new experimental findings.

This article discusses the paradoxical effects of valproic acid on hair, reporting both drug-induced hair loss and the potential for hair growth when used topically, but presents no original research findings.

In this study, a 3-month treatment with a 2940 nm Er:YAG laser, combined with conventional therapy, effectively reduced microfibrosis around hair follicles and increased hair growth in the anagen stage among 85 men with androgenetic alopecia.

This article reviews the biology of epithelial stem cells and their role in tissue self-renewal, maintenance, and regeneration, and it highlights the clinical implications of understanding their signaling pathways, but it presents no new clinical findings.

In this study, dermal papilla cell-derived exosomes accelerated hair follicle growth in mice, suggesting potential for treating hair loss by modulating key signaling pathways.

In this study, ectopic Wnt10b-mediated β-catenin activation in hair follicles resulted in larger regenerating anagen hair structures, an effect modulated by the Wnt inhibitor DKK1.

This study found that applying a tocotrienol-rich phytochemical topically induced hair follicle development in adult mice, revealing a new epidermal pathway involving E-cadherin and β-catenin.

This review discusses the potential role of extracellular vesicles in modulating hair follicle dynamics and reports no new clinical results; future investigations may inform treatment strategies for skin disorders.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.

This review suggests systemic changes in polycystic ovary syndrome may increase the risk of neurodegeneration, potentially linking it to Alzheimer's disease through common pathways affecting tryptophan metabolism.

This review critically assesses current topical therapies for scalp psoriasis and reports no new clinical results; the authors highlight the need for controlled trials to evaluate treatment efficacy.

This review discusses the regulation and function of vitamin D and its receptor in skin cells, highlighting their roles in processes such as proliferation inhibition, differentiation, and innate immunity, but reports no new results.

This review discusses the roles of Wnt signaling in skin organogenesis and related processes but reports no new experimental results, highlighting areas for future research.

This study found that different epidermal stem cell populations contribute to the formation of various skin tumors and new hair follicles following β-catenin activation in the adult epidermis.

This review discusses possible medication-induced hair loss and the need to exclude other confounding factors like stress and illness; it reports no new clinical findings and emphasizes careful assessment before attributing hair loss to medications.

This study reports the development of the first rodent model for androgenetic alopecia, demonstrating that overexpression of androgen receptors in mice delays hair regeneration and can be used to test new treatments.

This review provides a comprehensive overview of the mechanisms, efficacy, and adverse reactions of drugs commonly used for treating benign prostatic hyperplasia but reports no new clinical results.

In this study using a mouse model, Prom1+ dermal papilla cells were found to regulate the size of the papilla via β-catenin communication but did not aid in dermal repair.

This study found that combining fractional erbium-glass laser therapy with topical minoxidil significantly improved hair density and diameter in men with androgenetic alopecia compared to using minoxidil alone over a 24-week period, with no serious adverse events reported.

In this study, adenosine was found to stimulate hair follicle growth in vitro by promoting growth factor expression, β-catenin activation, and downstream signaling pathways.

This review discusses recent findings on molecular changes in cutaneous adnexal tumours and reports novel markers and pathways involved, highlighting the diverse oncogenic drivers and tumour suppressor alterations.

This review discusses how vitamin D and calcium signaling are essential for wound healing by activating epidermal and hair follicle stem cells, noting that deficiencies may lead to delayed or chronic wounds.

This study found that in a small cohort of patients with infections, tumor necrosis factor levels varied, challenging the interpretation that these levels are transient in gram-negative sepsis.

This study found that testosterone enhances insulin secretion in human pancreatic islets by being converted into DHT and E2, processes that are necessary for this effect.

This study found that dihydrotestosterone (DHT) suppresses prostaglandin E2 and TGF-β induced IGF-I gene promoter activity in osteoblasts, suggesting complex interactions among bone growth regulators and potential complications from anabolic steroid use.

This study supports the idea that angiolymphoid hyperplasia with eosinophilia is an inflammatory process linked to immunologic injuries rather than a proliferative condition.

This study suggests that an in ovo injection of CHIR-99021 promoted feather growth and follicle development in goose embryos by activating the Wnt signaling pathway.
