GlossaryCYP17A1 (Cytochrome P450 17A1)

enzyme crucial for steroid hormone production

CYP17A1, also known as Cytochrome P450 17A1, is an enzyme that plays a crucial role in the production of steroid hormones. It is involved in the conversion of pregnenolone and progesterone into their 17-alpha-hydroxylated products, which are precursors for androgens and estrogens. This enzyme is essential for the synthesis of hormones that regulate various bodily functions, including metabolism, immune response, and sexual development.

community here is why isotretinoin might cause hair loss and maybe why dupa happens.

in Research/Science 7 upvotes 1 year ago

Isotretinoin may cause hair loss by increasing DHT through a precursor androgen, DHEAS. Treatments like topical antiandrogens (RU58841, pyrilutamide) and drugs increasing PPAR-y expression (pioglitazone) might prevent this hair loss.
