Androgens and estrogens are crucial for insulin secretion in males.
research Stereocontrolled synthesis of all eight stereoisomers of the putative anti-androgen cyoctol
Scientists made all eight versions of a compound called cyoctol, but found it's not an anti-androgen and it fully breaks down in the skin.
research Epidermal Wnt/β-catenin signaling regulates adipocyte differentiation via secretion of adipogenic factors
Epidermal Wnt/β-catenin signaling controls fat cell formation and hair growth.
research Realising the therapeutic potential of neuroactive steroid modulators of the GABAA receptor

research Steroids excreted by human skin. I. C19-steroids in axillary hair.
Human skin releases different steroids, with some coming from sebaceous glands and others from sweat glands.
research [G-proteins, receptor signal transduction, and growth hormone secretion].
The document concludes that antiandrogenic drugs like cyproterone acetate and spironolactone are effective but not permanent treatments for skin-related androgenization in women.
research Serine Biosynthesis In Human Hair Follicles By The Phosphorylated Pathway: Follicular 3-Phosphoglycerate Dehydrogenase
research The Function of 5α-reductase in Related Diseases
5α-reductase enzyme affects hormone levels, influencing conditions like acne and hair loss.
research Endogenous steroid hormones in hair: Investigations on different hair types, pigmentation effects and correlation to nails
Body hair isn't a good substitute for scalp hair in steroid analysis.
research Determination of steroid hormones in human hair as a retrospective biomarker with HPLC-MS/MS
A new method accurately measures long-term hormone levels in hair.
research Studies on neurosteroids XXIV. Determination of neuroactive androgens, androsterone and 5α‐androstane‐3α,17β‐diol, in rat brain and serum using liquid chromatography–tandem mass spectrometry
The methods accurately measured brain androgens, showing most 5α-androstane-3α,17β-diol comes from outside the brain, while androsterone is both transported and made in the brain.
research Genetic regulation of the androgen receptor—A study of testicular feminization in the mouse
The study concludes that a genetic mutation in TFM mice leads to reduced androgen receptor activity, affecting the body's response to male hormones.
research Local and systemic mechanisms that control the hair follicle stem cell niche
research Cortisol Enhances the Expression of mac25/Insulin-Like Growth Factor-Binding Protein-Related Protein-1 in Cultured Osteoblasts**This work was supported by NIDDK Grant DK-45227 and a scholarship (to R.C.P.) from Fundacao Coordenacao de Aperfeicoa mento de Pessoal de Nivel Superior (CAPES), Universidade de Sao Paulo (Sao Paulo, Brazil).
Cortisol increases a specific protein in bone cells, which may help explain its negative effects on bone.
