research More about X‐linked testicular feminization of the mouse as a noninducible (is) mutation of a regulatory locus: 5α‐androstan‐3α‐17ß‐diol as the true inducer of kidney alcohol dehydrogenase and ß‐glucuronidase
A specific metabolite, not a receptor protein, triggers the production of certain kidney enzymes, but this process is disrupted in mice with a mutation causing testicular feminization.
research 17α‐estradiol induces aromatase activity in intact human anagen hair follicles ex vivo
17α-estradiol boosts aromatase activity in female hair follicles, potentially helping with hair loss.

research Clinical biochemistry of dihydrotestosterone
Understanding how DHT works is important for diagnosing and treating hormone-related disorders.
research Localization, Age- and Site-Dependent Expression, and Regulation of 11β-Hydroxysteroid Dehydrogenase Type 1 in Skin
Increased 11β-HSD1 activity in skin may contribute to aging and could be targeted to reduce aging effects.
research Activity of type 1 5α-reductase is greater in the follicular infrainfundibulum compared with the epidermis
The enzyme type 1 5α-reductase is more active in the hair follicle's lower part than in the skin's outer layer.
research Expression of steroidogenic enzymes in human sebaceous glands
Human sebaceous glands contain enzymes that affect androgen production and may influence sebum production and acne.
research Expression of mRNA for androgen receptor, 5alpha-reductase and 17beta-hydroxysteroid dehydrogenase in human dermal papilla cells
Hair sensitivity to androgens is partly controlled by specific enzyme expressions in different hair areas.
