This research found that Foxc1 transcription factor and COL17A1 are critical in regulating quiescence and hair thinning in hair follicle stem cells, with aging-related DNA damage leading to hair loss.

Understanding where cancer cells come from helps create better prevention and treatment methods.

This article discusses the treatment considerations for a 17-year-old boy with a six-month history of acne but reports no new research findings.

This study found that PM2.5 exposure induced oxidative stress in human keratinocytes and mouse skin, causing cellular damage, which was mitigated by the antioxidant N-acetyl cysteine.

This guideline outlines the management of systemic lupus erythematosus in adults but reports no new clinical findings.

This review discusses recent advances in skin penetration mechanisms, specifically focusing on the enhanced understanding of the follicular pathway and its implications for transdermal therapies, immune system targeting, and nanoparticle safety.

This study found that dermal papilla and peribulbar dermal sheath cup cells in mice can both induce hair follicle formation, suggesting they may have similar functional roles in hair growth.

This review discusses the use of antiandrogens like flutamide and its derivatives in prostate cancer treatment and highlights the need for next-generation antiandrogens for improved efficacy; it reports no new clinical results.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

In this study, androgen did not affect keratinocyte growth in coculture with androgenetic alopecia-derived dermal papilla cells, but did significantly suppress keratinocyte growth when androgen receptor was overexpressed in the papilla cells.

This review discusses the role of regulatory T-cells in tissue repair and regeneration across various organs and reports no new clinical results.

This study identified 19 specific genes involved in root hair growth and morphogenesis in Arabidopsis, using a combination of computational and experimental methods.

This study reported that spironolactone at 200 mg/day significantly improved facial hair growth in women with hirsutism and showed a sustained reduction in ovarian androgens over one year.

This study suggests that apoE4 may contribute to cognitive decline by reducing androgen receptor levels in the brain, but androgen treatment improved memory deficits in female mice expressing human apoE4.

This study reported that toxic shock syndrome, originally noted in children, is now predominantly associated with menstruating women, with some experiencing recurrence and complications like vocal cord paralysis and impaired finger sensation.

This study found that macrophages near hair follicles contribute to the activation of skin epithelial stem cells in mice, suggesting a novel role for macrophages in regulating hair growth.

This study found that TRPV1 activation in human scalp hair follicles inhibited hair shaft elongation, suppressed proliferation, and induced apoptosis, suggesting TRPV1 as a potential target for managing hair growth and epithelial disorders.

This study found that squamous cell carcinomas from hair follicle stem cells are more prone to epithelial to mesenchymal transition and metastasis than those from interfollicular epidermis, due to distinct chromatin landscapes.

This study found that Wnt signalling activates hair follicle fate in hair follicle stem cells by relieving TCF3/4–TLE-mediated repression, with β-catenin being crucial for this process.

Mammalian organs regenerate using stem cells and cell plasticity, but this ability declines with age.

The researchers reported that DHT-inducible DKK-1 may play a significant role in DHT-driven balding by inhibiting hair follicle cell growth and promoting apoptosis in androgenetic alopecia.

This review outlines the various processes activated by the peptide GHK-Cu in tissue remodeling and reports improvements in skin and wound healing but notes a need for further study to fully understand these mechanisms.

This forum article in BMC Biology discusses evolving views on the concept of the stem cell niche, highlighting varied mechanisms and the need for better understanding of the niche's roles and functions.

Dermatoscopy and videodermatoscopy are useful for diagnosing and monitoring various skin, hair, and nail conditions.

This study observed that tributyltin pollution induces imposex, reduces reproductive success, and leads to population decline in Ocinebrina aciculata, highlighting its sensitivity compared to other prosobranch species.

Humans lost body hair relatively recently in evolution.

This review discusses nonclassical 21-hydroxylase deficiency as the most common autosomal recessive disorder in humans and highlights the effectiveness of glucocorticoid treatment in reversing related symptoms.

This study reports that three synthesized PSMA-targeted radioimaging agents demonstrated high affinity and specific localization to prostate cancer tumors in a mouse model, highlighting their potential for cancer detection and monitoring.

This study found that activating the Sonic hedgehog pathway in scarring wounds can remodel the dermis to promote hair follicle regeneration, highlighting a potential new approach to enhance healing.

This review discusses the WNT signaling pathway's involvement in human diseases and highlights recent advances in WNT-related treatments, but it presents no new research findings.
