This study observed that higher childhood levels of DHEAS were associated with more advanced pubertal development and correlated with changes in DNA methylation near puberty-related genes in both boys and girls, potentially explaining the hormone's influence on puberty.

There is not enough evidence to support health claims about soy isoflavones.

In this study, 4‐MAPC treatment reduced ventral prostate weight in rats primarily through decreased synthetic activity, with testosterone propionate increasing prostate weight and activity at pharmacologic doses.

This study investigated hair fibre growth in Angora and Cashmere goats, finding differences in growth rates and seasonal dependencies, and examined the effects of prolactin and melatonin on protein deposition in hair follicles.

This study found that maternal early-pregnancy serum ferritin concentrations were associated with lower DNA methylation levels at specific CpG sites in cord blood, with some associations persisting into childhood.

This study suggests that high concentrations of minoxidil may prolong the proliferative capacity of keratinocytes, which may partially explain its positive effect on hair growth.

This study found that relatively low concentrations of 1,25(OH)2D3 stimulated human hair follicle and fiber growth, while higher concentrations inhibited growth in a whole-organ culture system.

In this study with cultured C_57BL/6J mouse hair follicles, ginseng extract at a concentration of 0.1 mg/ml was reported to best promote hair growth.

This study reports that melatonin influenced HaCaT cell proliferation, with high concentrations reducing DNA synthesis and low concentrations enhancing it after 24 hours.

This study found that prolactin and melatonin both stimulated hair shaft elongation in Cashmere goat hair follicles, with maximum growth observed at specific concentrations, although melatonin reduced follicle viability after 96 hours.

In this study, minoxidil sulphate was observed to significantly increase DNA synthesis in cultured human hair follicles in a concentration-dependent manner.

This study found that DNA damage in obese women was linked to serum 25-hydroxyvitamin D and hair chromium levels, with higher serum vitamin D associated with less damage and higher chromium with more damage.

This study found that WD-aptamer increased β-catenin expression and promoted human hair follicle dermal papilla cell proliferation by interfering with the CXXC5-Dvl1 interaction in the Wnt signaling pathway.

This study found that inducing hair follicles into the anagen-onset stage in mice enhances the immune response to a topically applied DNA vaccine against anthrax.

This study identified a novel V26M mutation in the vitamin D receptor as the cause of hereditary vitamin D resistant rickets in a patient, characterized by severe rickets and an unusual pattern of alopecia.

In this study, pantothenic acid at 20 μg/ml was observed to promote dermal papilla cell proliferation and migration, likely through up-regulation of ID3 and inhibition of Notch signaling.

This study found that organ-cultured human scalp hair follicles can mimic chemotherapy-induced damage in vivo and serve as a model to explore molecular targets and protective agents for hair follicle preservation.

This study found that high exposure to air pollutants like SO2, NO, NO2, NOx, and PM2.5 was linked to a significantly increased risk of developing PCOS in women.

Wool follicles can grow in a lab with the right nutrients and conditions.

In this study using lab models, YangHyulEum Gami-Bang (YHEG) was associated with promoting hair growth and inhibiting factors that contribute to hair loss.

This study demonstrated that elevated GABA levels can worsen stress-induced hair growth inhibition in mice, while GABAA antagonists like ginkgolide A may help alleviate these effects.

In this study, biotin supplementation was found to significantly increase wool follicle viability and metabolic activity in vitro, with the highest effects observed at 0.5 mg L⁻¹ concentration.

This study found that retinoic acid pre-treatment enhanced the efficiency of gene transfer into mouse skin for potential therapeutic applications.

This study found that the combination of MT-DADMe-ImmA and MTA selectively induced apoptosis in head and neck squamous cell carcinoma cell lines FaDu and Cal27, but not in normal fibroblasts or MTAP-deficient breast cancer cells.

This study found that murine skin is a target for melatonin bioregulation, as melatonin affected DNA synthesis and tyrosinase activity in skin organ culture.

This study observed that minoxidil specifically increased DNA synthesis in hair follicle cells, suggesting its distinct mechanism of action in promoting hair growth compared to cyclosporin, which showed no direct proliferative effect on these cells.

This study found that a high-energy shock wave can increase osteogenic activities in human mesenchymal cells, offering insights into potential therapeutic targets for trauma-induced heterotopic ossification.

This study found that prolonged use of finasteride and dutasteride in young men with androgenic alopecia is linked to a decline in semen quality over time, particularly affecting sperm motility and DNA integrity, with dutasteride showing a slightly greater impact than finasteride.

This review discusses the role of norepinephrine release and protein kinase C activation in the development of benign prostatic hypertrophy, suggesting potential targets for new therapies, but it reports no new clinical results.

This study found that Danthron induced apoptosis in a human malignant melanoma cell line through mitochondrial, endoplasmic reticulum, and death receptor pathways.
