This review investigates molecular mechanisms behind PCOS pathogenesis and discusses potential therapies, but reports no new clinical results.

This study suggests that the testosterone analogs 7α-Methyltestosterone and 7α-Ethyltestosterone may offer promising androgenic, progestogenic, and anabolic properties for development as male contraceptives.

This study suggests that extracellular vesicles from prostate cancer cells could aid in identifying tumor heterogeneity and serve as biomarkers, while also playing a role in SARS-CoV-2 infection in nasopharyngeal mucus.

This review discusses the potential role of androgens in COVID-19's pathophysiology and their possible link to hair disorders, but reports no new clinical results.

This study established the R-7 dermal papilla cell line, which retained essential characteristics of primary cells without undergoing malignant transformation, suggesting its potential for future hair research.

This study identified a genetic locus associated with rhabdomyosarcoma susceptibility in mice and found that specific differentiation markers are linked to the regression of basal cell carcinoma.

In this study, high expression of S100A4 in glioblastoma was associated with worse patient survival and promoted tumor progression by enhancing pro-tumorigenic vascular functions.

This study found that strontium ranelate may promote cartilage regeneration by enhancing chondrogenic differentiation and inhibiting the Wnt/β-catenin signaling pathway in rat models of cartilage defects.

This study reports two siblings with severe combined immunodeficiency due to a mutation in the FOXN1 gene, characterized by T-cell immunodeficiency, alopecia totalis, and nail dystrophy.

The study found that dermal EZH2 plays a crucial role in coordinating dermal fibroblast differentiation and epidermal development by modulating Wnt/β-catenin and retinoic acid signaling.

This study found that the Polycomb Repressive Complex 2, particularly its component Ezh2, is crucial in regulating dermal fibroblast differentiation and epidermal keratinocyte proliferation during murine skin development.

In this study, the researchers observed that Biofield Energy Healing Treatment significantly increased hair follicle cell proliferation in human dermal papilla culture, suggesting potential as a hair growth enhancer.

This research suggests that mouse mutants and genomics can help study hair biology and epithelial differentiation by focusing on the role of the Foxn1 gene.

This study identified a new cis-regulatory element in the mouse Hr gene that influences its expression in skin and brain cells, highlighting a complex molecular network involved in hair follicle formation.

This review discusses the interplay between signaling/transcription factor-mediated and epigenetic mechanisms in skin development and regeneration, highlighting the need for further exploration of epigenome reorganization in these processes.

This study suggests that unliganded vitamin D receptors in mice may cause more severe skeletal and mineral ion defects than VDR-null conditions, and vitamin D analogues may restore function in specific VDR mutations.

This article discusses the ongoing care needs for individuals with 21-hydroxylase deficiency due to mutations in the CYP21A2 gene but does not present new clinical findings.

This review discusses the conditions, genetic factors, and treatment options related to polycystic ovary syndrome, but reports no new clinical findings, emphasizing the need for future research.

Skin-derived stem cells could help treat skin aging and pigmentation issues.

Some nutrients and antioxidants may improve skin and hair health, but more research is needed to confirm these benefits.

In this study, the activation of Notch1 signaling in keratinocytes was found to play a key role in recruiting immune cells and facilitating skin repair after injury.

This review provides an update on sex hormone-associated dermatoses in dogs, detailing known conditions like feminization syndrome and exploring less understood issues such as alopecia X, without presenting new clinical findings.

This study reported that high cholesterol levels were linked to increased prostate cancer risk, while selenium supplementation affected gene expression, suggesting nutritional and clinical factors might influence prostate cancer risk and biology.

This study found that knock-down of keratin 15 in various cell lines affected cell spreading, morphology, migration, differentiation, and proliferation, suggesting its role in maintaining the stem cell nature of keratinocytes.

Some treatments like topical oxygen and stem cells show promise for wound healing and hair growth, but evidence for modern dressings over traditional ones is limited.

This review discusses the roles of the hairless (HR) protein as a corepressor, particularly its impact on RORα-mediated transcriptional repression, and reports no new experimental findings.

This review discusses various syndromes of severe insulin resistance, their biochemical and clinical features, and potential therapeutic options, but it reports no new clinical results.
