1 CYP17 enzyme catalyzes an important step in sex steroidogenesis and is responsible for the biosynthesis of dehydroepiandrosterone (DHEA) and androstenedione in the adrenals. Dehydroepiandrosterone cytochrome P450 family 17 subfamily A member 1 Homo sapiens
2 CYP17 enzyme catalyzes an important step in sex steroidogenesis and is responsible for the biosynthesis of dehydroepiandrosterone (DHEA) and androstenedione in the adrenals. Dehydroepiandrosterone cytochrome P450 family 17 subfamily A member 1 Homo sapiens
3 The precursor substrate of CYP17, pregnenolone, was added to control and exposed H295R cells, and enzymatic production of DHEA was measured using a radioimmunoassay. Dehydroepiandrosterone cytochrome P450 family 17 subfamily A member 1 Homo sapiens
4 Replacement of the 6-OH group by a 6-CH(3)O group eliminated this cytotoxic effect, but CYP17 activity measured as DHEA production was still significantly inhibited. Dehydroepiandrosterone cytochrome P450 family 17 subfamily A member 1 Homo sapiens
