In this study, ethanol discontinuation in Y 1 R / LacZ transgenic mice significantly decreased neuropeptide Y immunoreactivity and increased Y 1 receptor gene expression in the amygdala, with evidence suggesting an important role for the progesterone metabolite 3α,5α‐TH PROG in these changes.

This study found that the estrous cycle influences the effect of the δ-GABAAR agonist THIP in reducing binge drinking behavior in female mice, with receptor expression elevated during diestrus.

This study found that preserving hair grafts in platelet-rich plasma before implantation significantly improved hair density, graft uptake, and hair thickness compared to saline preservation in hair transplantation patients.

This study suggests that Ptprq in the hair bundles may exist as multiple isoforms that are differentially expressed throughout development and affect the organization of stereocilia in the chick inner ear.

This article discusses the potential for topical caffeine as a natural alternative for treating androgenetic alopecia due to its ability to penetrate skin, but it reports no new clinical findings.

This guide provides a comprehensive approach to diagnosing periocular hair disorders, which can range from benign conditions to those posing serious health risks.

In this study, microarray and proteomic analyses indicated that genes involved in immune response, receptor binding, and growth factor activity might influence wool fibre diameter in sheep.

This study found that Ishige sinicola extract stimulated osteoblast differentiation and bone formation in MC3T3-E1 cells, suggesting potential use for osteoporosis prevention and treatment.

Clascoterone safely promotes hair growth similar to minoxidil.

This study found that a herbal shampoo and solution were more effective than placebo in reducing hair loss and improving hair growth in participants with androgenetic alopecia and telogen effluvium.

In this study, yeast fermentation of Platycladus orientalis leaves was shown to enhance hair growth-promoting properties by affecting cell cycle phases in human dermal papilla cells, increasing growth factor VEGF, reducing inflammatory factor TGF-β1, and altering the expression of Wnt/β-catenin pathway-related genes.

This study found that umbilical cord mesenchymal stem cell-derived exosomes improved hair growth in mice with androgenetic alopecia by promoting hair follicle stem cell stemness through the RAS/ERK pathway, suggesting a potential new treatment strategy for this condition.

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 review discusses treatments for androgenic alopecia, noting that current options like finasteride and minoxidil are effective for only 10% of patients, thus highlighting the need for new therapies.

This article discusses various holding solutions for hair transplant grafts and reports no new research findings; the authors emphasize the need for comparative studies.

This review discusses available treatments for androgenetic alopecia in men, like finasteride and 5% minoxidil, and notes that hair growth results are unpredictable and often driven by industry-sponsored studies.

This paper discusses the role of steroid sulfatase in hormone-dependent tumors and highlights the development of potent inhibitors, noting the commencement of a phase I trial for one inhibitor in postmenopausal breast cancer patients.

This review discusses the cutaneous serotoninergic/melatoninergic system's potential role in skin function and resilience against environmental and internal stresses, but does not report new experimental findings.

This study found that p2y5 functions as a novel LPA receptor involved in the G13-Rho signaling pathway, with implications for human hair growth, and proposes renaming it to LPA6.

This study found that neurosteroids can reorganize GABA A receptors in mice, mimicking ovarian cycle changes, with the process being mediated by neurosteroid levels rather than direct hormone receptor activation.

This paper discusses key mechanisms of androgen metabolism in androgenetic alopecia and reports the effectiveness of treatments like oral finasteride and topical minoxidil, highlighting the limited success rate due to factors like follicular inflammation.

This study identifies SOX9 as a critical downstream effector of ERG in TMPRSS2:ERG fusion-positive prostate cancer, indicating its role in tumor invasion and growth.

This article discusses the potential role of melatonin in protecting skin against stress and maintaining homeostasis, based on its local synthesis and various protective functions, but presents no new clinical results.

This study found that SZ95 sebocytes and HaCaT keratinocytes exhibit distinct enzyme expressions and activities, implicating their different roles in androgen metabolism and homeostasis in vitro.

This study found significant species differences in the enzyme activity and inhibitor affinities of prostatic 5α-reductases from rats, dogs, and humans, with variable potencies for different 3-oxo-4-azasteroid inhibitors across species.

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 found that 88% of women with female pattern hair loss who received oral antiandrogens saw no progression or improvement in their condition.

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.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.
