This study found that male 5α-reductase 2 knockout mice showed deficits in social dominance behaviors and reduced dopamine receptor binding in a brain region related to social ranking.

This review examines rodent models to explore how maternal conditions like undernutrition, obesity, hypoxia, and androgen exposure affect fetal programming and metabolic outcomes in offspring, but presents no new clinical findings.

This hypothesis article explores frontal fibrosing alopecia as a potential autoimmune condition and calls for future research to investigate this possibility, but reports no new clinical results.

The testes significantly contribute to vitamin D metabolism and may affect male reproductive health and conditions like hair loss.

This study found that sebaceous glands in the skin are primarily renewed by their own stem cells during normal conditions, but after injury, they regenerate through stem cells from hair follicles, highlighting stem cell plasticity and regeneration capabilities.

This article reviews the therapeutic potential of potassium channel openers for various conditions related to metabolic distress but does not report new clinical results; it emphasizes the need for further research.

This review discusses the potential applications of adipose-derived stromal cells for treating conditions like colitis, liver failure, and more, without presenting new clinical results.

This case report describes a 7-year-old boy with alopecia areata and reduced vitamin D receptor expression whose condition improved after using calcipotriol, a strong vitamin D analog.

This study explores how SARS-CoV-2 interacts with endocrine organs and highlights specific endocrine molecules that help explain the progression and outcomes of COVID-19, especially in patients with certain metabolic conditions.

This study found that in mice, knockout of Rac1 and Rac3 in keratinocytes led to reduced white adipose tissue and revealed Rac-dependent paracrine pathways affecting pre-adipocyte differentiation.

This review discusses the molecular mechanisms of masculinization involving androgen signaling and their roles in male embryonic development and conditions like hypospadias and prostate cancer, and reports no clinical results.

This study suggests that hormone replacement therapy and oral contraception may have a protective role in scarring alopecia, as these were reported less frequently by patients with the condition compared to those with female pattern hair loss.

In this study, researchers suggest that hair follicle miniaturization in conditions like androgenetic alopecia may result from impaired conversion of quiescent stem cells to progenitor cells, influenced by the follicular niche, its collagen network, and various mechanical constraints.

This study suggests that dsRNA may enhance KRT9 expression in palm and sole skin through β-catenin signaling, potentially linking mechanical damage to specific skin features and certain skin conditions.

This review summarizes existing knowledge of how the WNT signaling pathway affects mesenchymal stem cells under various conditions, highlighting challenges and mechanisms for clinical applications.

This review examines testosterone's role in male health and aging but reports no new clinical results; the authors highlight the need for further research on optimal testosterone levels to prevent age-related conditions.

This study found that adipocytes in the interfacial white adipose tissue adjacent to fibrotic lesions in systemic sclerosis show unique phenotypes and contribute to the condition's pathogenesis.

This study revealed that Vav2 and Vav3 play roles in regulating hair follicle bulge stem cells in normal conditions and cancer stem cell activation and remodeling in mice.

This study reports that the peptide GPIGS, found in Bacillus sp. M18 conditioned medium, may promote hair growth through the PI-3K/Akt pathway and accelerate hair regrowth in mice.

Genetic mutations cause various hair diseases, and whole genome sequencing may reveal more about these conditions.

This review discusses melanocytes' role in pigmentation, their clinical significance in conditions like vitiligo and hair graying, and highlights current research on hair follicle regeneration without reporting new clinical results.

This study found that the protein p63 requires morphogenetic signals to regulate gene expression effectively during skin cell differentiation, highlighting its complex role in therapeutic reprogramming for conditions like epidermolysis bullosa.

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 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 demonstrates that Puerariae Lobatae Radix may regulate skin lipid metabolism by inhibiting sebaceous gland growth and reducing triglyceride secretion, highlighting its therapeutic potential for sebaceous gland-related conditions.

This review discusses the functions and potential therapeutic targeting of TRP ion channels in the skin, noting their involvement in both physiological processes and various pathological conditions, but reports no new experimental results.

In this review, researchers explored the multifaceted role of NF-κB signaling in various biological processes and diseases, including its interactions with other pathways, and discussed possible therapeutic approaches targeting this pathway for treating conditions like cancer, autoimmune disorders, and COVID-19.

This study demonstrated that EdnrB signaling promotes melanocyte stem cell proliferation and differentiation, enhancing hair and epidermal melanocyte regeneration, especially under conditions of active Wnt signaling.

This study found that sweat gland stem cells primarily maintain sweat gland homeostasis but can trans-differentiate to aid in epidermal healing and regenerate diverse skin structures under certain conditions.

This article reviews the possible therapeutic activities of Angelica gigas Nakai root extracts and their components, noting their potential effects on neuro-cognitive, metabolic, and other health conditions, and reports no new clinical results.
