This study observed that inflammatory stimuli significantly altered gene expression in rat theca-interstitial cells, affecting pathways related to growth and androgen production, which are central features of polycystic ovary syndrome.

In this study, the administration of indole-based compounds, particularly L-Tryptophan and Tryptophol, to a PCOS-induced rat model resulted in an increased number of healthy ovarian follicles and a reduction in ovarian cysts compared to untreated rats, suggesting potential therapeutic efficacy.

This study found that hair from mice with the Naked trait mutation has significantly lower levels of glycine and tyrosine, suggesting a deficiency in a specific protein fraction.

This study found that resveratrol improved ovarian function, menstrual irregularities, hair loss, and sex hormone levels in patients with polycystic ovary syndrome compared to placebo.

PCOS may have evolved as an advantage in past environments with food scarcity.

This review discusses the role of hormones in acne vulgaris and highlights the need for further research on their mechanisms of action; it reports no new clinical results.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This study found that overexpressing the BMP inhibitor Noggin in transgenic mice led to a significant loss of nontylotrich hair follicles, suggesting a critical role for BMP signaling in hair follicle morphogenesis and cycling.

This study found that prolactin is a key regulator of keratin expression in human hair follicles, enhancing specific keratin types and influencing epithelial stem cell-associated keratins.

In this study, enteroendocrine cells were shown to coordinate intestinal stem cell migration towards a wound in Drosophila by releasing a ligand that activates non-canonical Wnt signaling, aiding efficient tissue repair.

This article proposes three mechanisms by which dihydrotestosterone may contribute to baldness but reports no new research findings.

This study reports the creation of rat liver stem cell lines that can differentiate into hepatocytes and suggests they might be useful for pharmacological and regenerative medicine applications.

This study found that SDR5A1 gene expression was similar between hirsute women, normal women, and men, suggesting it may not explain differences in hair growth among these groups.

This study focused on the ultrastructural and immunohistochemical aspects of dermal mast cells in systemic mastocytosis and their interaction with the epidermal melanin unit.

This review discusses polycystic ovary syndrome, emphasizing its broad range of manifestations and associations with risks like type 2 diabetes and cardiovascular events, but reports no new clinical results.

This review discusses the evolution of diagnostic criteria for polycystic ovary syndrome and emphasizes its association with various metabolic and cardiovascular risks, but it provides no new research findings.

This publication reviews the World Professional Association for Transgender Health's Standards of Care for supporting transgender and gender nonconforming people, with adjustments needed for diverse global contexts and no new clinical results.

This research highlights that engineered mice lacking the vitamin D receptor show multiple health issues similar to human vitamin D deficiency, underscoring the widespread impacts of the vitamin D endocrine system.

This consensus report reviews current knowledge and identifies knowledge gaps concerning the various health aspects of polycystic ovary syndrome, without presenting new clinical findings.

This guideline from the Endocrine Society recommends using the Rotterdam criteria for diagnosing polycystic ovary syndrome and outlines first-line treatments, emphasizing hormonal contraceptives and lifestyle intervention.

This paper reviews the diagnostic criteria, associated morbidities, and possible evolutionary advantages of polycystic ovary syndrome, but does not report any new findings.

This article reviews the clinical features, diagnostic criteria, and possible genetic and environmental influences of polycystic ovary syndrome but provides no new research findings.

This review discusses the current understanding of polycystic ovary syndrome, focusing on its epidemiology, pathophysiology, diagnosis, management, and future research directions, but reports no new clinical results.

The guideline recommends mental health involvement in diagnosing gender identity disorder and outlines hormone and surgical treatment protocols, emphasizing safety, informed consent, and long-term monitoring.

Hair follicles can regrow in wounded adult mouse skin using a process like embryo development.

This review explores how adult skin epithelia preserve stem cell populations for hair follicle regeneration and wound healing, but reports no new experimental results.

Different types of long-lasting stem cells are responsible for the growth and upkeep of the mammary gland.

This review discusses the biochemical and biological functions of histone demethylases and their potential involvement in human diseases, including cancer, but reports no new findings.

This review discusses the role of androgens in the progression of cardiovascular disease and explores novel therapeutic targets without reporting new clinical results.
