This study found that HDAC6 plays a crucial role in regulating primordial follicle activation, with its overexpression delaying activation and preserving fertility by reducing NGF levels.

This study investigated how vitamin A deficiency, certain diseases, and pregnancy affect cattle coat hair structure, finding notable keratin fibril interference under vitamin A deficiency and structural modifications in chronic renal failure, while pregnant cows exhibited superior hair tensile strength compared to non-pregnant ones.

This source discusses the complexity of cancer research, emphasizing that despite extensive studies, a comprehensive understanding of metastatic progression and therapeutic development remains elusive, and underscores the importance of animal models in breast cancer research.

This study found that inhibiting AP-1 transcription factors in mice causes squamous tumors to transform into sebaceous tumors and regulates tumor cell lineage.

This study found that inhibiting AP-1 activity in mice can induce lineage transdifferentiation between squamous and sebaceous tumors, suggesting AP-1's role in maintaining tumor cell identity.

In this study, a very low-calorie ketogenic diet significantly improved metabolic and hormonal profiles in obese men, but did not significantly enhance most semen parameters except for sperm motility.

This study found that in a sample of girls and adolescents aged 15–24 years, the prevalence of PCOS was 22.5% according to the Rotterdam criteria.

COVID-19 can cause different types of hair loss, with telogen effluvium being the most common.

Among females with nonclassical 21-hydroxylase deficiency, this study found that low-dose glucocorticoid treatment improved fertility outcomes by increasing pregnancy and live birth rates while reducing miscarriage rates.

This study concluded that STK11 gene polymorphisms were not predictive of metformin response in women with PCOS, though they may influence alopecia and hirsutism.

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.

Alopecia in young women improves with effective treatment.

Gender affects hair and scalp characteristics, with differences in hormone responses, graying patterns, and trace metals.

This chapter reviews the presence and roles of stem cells in various body systems, focusing on their lifelong function in animals and humans, and reports no new experimental findings.

This study observed that Greek Caucasian women with PCOS had distinct serum hormone levels and a specific AKT2 gene SNP, which may play a role in the condition's characteristics.

This chapter reviews pharmacodynamic evaluations in endocrine disorders focusing on oral antidiabetics, insulin analogues, and hormone interactions, but reports no new results.

This review discusses hormones that affect acne and highlights a statistically significant link between a low-glycemic-load diet and reduced acne activity, but reports no new experimental findings.

The document concludes that accurate diagnosis of male and female gonadal disorders is crucial for effective treatment and better patient outcomes.

This study found that among women with polycystic ovary syndrome, higher age, obesity, hirsutism, and having children were independently associated with increased metabolic risk.

This workshop review from the Australian Hair and Wool Research Society discusses findings in cutaneous biology and endocrinology but presents no new research results.

Diphencyprone initially increases mouse hair growth, then slows it, possibly due to changes in specific protein levels.

In this study, hormonal abnormalities were detected in all investigated hirsute Saudi women, with elevated major androgens in 85.9% and polycystic ovaries in 59% of cases.

In this study, researchers observed that the sequence of maturity markers in normal boys showed specific time lags, with some markers appearing before and others after spermarche.

This review suggests a shift toward genetically informed treatments for male pattern hair loss by integrating genetic insights and pharmacogenetic markers into therapeutic decision-making.

This review reports that Fenugreek seeds contain compounds like Galactomannan and Trigonelline, which show anti-diabetic and anti-hyperlipidemic effects, while Fenugreek leaves have high saponin content, contributing to their anti-microbial activities.

This review reports that the treatment of androgenetic alopecia is shifting from single therapies to personalized, multimodal approaches incorporating both traditional and emerging pharmacologics, regenerative strategies, nutraceuticals, cosmeceuticals, and device-based interventions, with combination regimens showing improved outcomes.

This study introduces stem cell activity as a key factor influencing the effects of IFN-γ and TGF-β1 on autoimmune disease dynamics, showing that varying cytokine levels can modulate stem cell activity and immune privilege, impacting tissue regeneration and disease flares.

This review summarizes the application of genome wide association studies and selection signature analyses in sheep and goat breeding in China, highlighting genomic regions that influence traits like reproductive performance and body size.

This study found that intrinsic feedback loops are crucial for maintaining the function of human dermal papilla cells during hair growth, highlighting the importance of autocrine signaling and niche reprogramming for advancing hair follicle biology and regenerative therapies for hair loss.

In this animal study, hibiscus leaf simplicia ointment was found to protect red blood cell levels and promote better hair growth in UV-exposed rats, though it did not maintain normal skin histology; the ointment showed no significant acute dermal toxicity.
