In this study, rapamycin was found to increase hair follicle pigmentation and prolong anagen duration in cultured human scalp hair follicles, suggesting it could be explored as an anti-greying agent.

In this research, Sertoli cell line model ST38c demonstrated that the androgen receptor regulates hormone pathways through specific coregulators, suggesting roles for SRC-2 and HBO1 in testicular development and androgen responsiveness.

This study reports that stress-related neurohormones and factors, such as CRH and SP, can inhibit hair growth and alter immune functions in murine and human hair follicles.

This research discusses androgenic alopecia's potential role in severe COVID-19 symptomatology and suggests further exploration of the scalp's role in virus transmission.

In this study, researchers observed that metabolite expression patterns, including sugars, lipids, amino acids, and nucleotides, affect hair follicle growth in cashmere goats, with feeding practices potentially influencing these cycles via hormone and vitamin levels.

In this study, androgen receptors were found only in the mane follicles of red deer stags during the breeding season, suggesting their expression is induced by seasonal hormone changes.

This study explores the expression and function of 11β-HSD1 in human hair follicles and its potential regulation of glucocorticoid effects on dermal papilla cells, but reports no definitive findings on 11β-HSD1's role.

Male hormones control a specific gene in hamster skin, with different hormones having varying effects.

Protease Nexin-1 is found in human hair growth cells and is affected by male hormones.

Male hormones affect COVID-19 severity and certain drugs targeting these hormones could help reduce the risk.

This animal study observed that dihydrotestosterone increased arterial stiffness and decreased estrogen receptor expression in female mice, potentially impacting cardiovascular health in contexts of androgen use.

In this study, researchers found that the synthetic stress hormone dexamethasone caused opposite effects on hair growth-related proteins, reducing SFRP2 and increasing SFRP3, which respectively stimulate and inhibit hair follicle cell proliferation in human dermal papilla cells.

This paper discusses the role of androgen hormones in regulating sebum production and hair growth via androgen receptors in the pilosebaceous unit, but reports no new findings.

This study found that finasteride treatment in male rats altered steroid hormone homeostasis and caused kidney damage, suggesting potential risks for patients with renal dysfunction on androgen or antiandrogen therapy.

This study found that testosterone and dihydrotestosterone can induce growth factors from dermal fibroblasts, promoting keratinocyte proliferation and differentiation, which may contribute to sex hormone-related acne development.

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 study found that estrogen can cause reversible suppression of the hair cycle by inducing premature catagen and maintaining the telogen phase without damaging the hair follicle stem cell niche or the signature gene expressions of dermal papilla cells.

This review discusses sex differences in immune responses and highlights mechanisms involving sex hormones, X-linked genes, and X-Chromosome Inactivation, but reports no new clinical findings.

This study found that normal murine hair follicles are direct targets for melatonin bioregulation, expressing receptors that are regulated in a hair cycle-dependent manner, influencing keratinocyte apoptosis.

This review examined how COVID-19 infection and vaccination might affect sexual activity, sex hormones, and menstrual cycles in men and women, and found no evidence of COVID-19 transmission via semen.

This study found that rice bran ash extract and orthosilicic acid both increased melanin synthesis and related protein expression in melanocytes, suggesting potential therapeutic use for melanin deficiency.

This study found that elevated carbon dioxide levels may help mitigate water deficit stress in soybean roots by altering gene expression related to stress and nutrient transport.

This study found that sulforaphane may help alleviate hair loss by increasing hair count after 18 weeks of use and enhancing the expression of a DHT-degrading enzyme in cellular models.

This study found that systemic testosterone exposure in transgender individuals with XX genotype alters skin biology, increasing androgen and estrogen receptor-positive cells, collagen density, and fibronectin expression while reducing immune cells, which could affect surgical outcomes by promoting a male skin phenotype.

This study successfully established a functionally stable immortalized sheep granulosa cell line (GCs-SV40T-GFP) that can passaged up to 50 generations, maintaining morphological stability and estradiol secretion, offering a valuable model for research into animal reproductive function and hormone regulation.

Personalized medicine is important for treating skin disorders, with new treatments and connections to hormones and genetics being explored.

This study examined the effects of constant-release melatonin on the SOX21 gene in Inner Mongolia Cashmere goats, finding that it stabilized gene expression and reduced stress responses with notable expression changes except in March, April, and May.

In this study, bromocriptine's inhibition of prolactin promoted secondary follicle development during anagen in cashmere goats, likely via changes in specific gene expressions, despite not affecting fiber characteristics or primary follicle activity.

This study found that androgen impacted glucocorticoid signaling in the mouse brain only in the prefrontal cortex and substantia nigra, suggesting limited interaction between these hormones at high corticosterone levels.

In this literature review, researchers explored current screening options for reproductive health disorders, noting the need for biomarker development for endometriosis and polycystic ovary syndrome, while supporting anti-Mullerian hormone testing and pathogen detection for ovarian reserve and sexually transmitted infections respectively.
