Such shifts were not observed for the low-spin EPR signals. 25-hydroxycholesterol 126-147 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 77-95 26230055-2 2015 Addition of cholesterol 25-hydroperoxide to the enzymes CYP27A1 and CYP11A1 induced well-defined spectral changes while generating 25-hydroxycholesterol as the major product. 25-hydroxycholesterol 131-152 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 68-75 8490050-7 1993 The rate of side-chain cleavage of 25-hydroxycholesterol by human cytochrome P-450scc in Tween-20 micelles was low, the highest rate being about 1% of the Vmax for cholesterol. 25-hydroxycholesterol 35-56 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 66-85 9002660-2 1997 Human placental syncytiotrophoblasts were cultured for 48 h with estradiol, and P450scc activity was determined by the formation of progesterone from 25-hydroxycholesterol. 25-hydroxycholesterol 150-171 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 80-87 1525044-4 1992 The role of different steroids in the regulation of P450 cholesterol side-chain cleavage enzyme (P450scc) and 3 beta-hydroxysteroid dehydrogenase (3 beta-HSD) was evaluated by measuring the conversion of P4 derived from unlabelled 25-hydroxycholesterol and from labelled pregnenolone, respectively. 25-hydroxycholesterol 231-252 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 97-104 2598930-4 1989 25-Hydroxycholesterol proved to be a suitable substrate for determining the maximum rate of pregnenolone synthesis by cytochrome P-450scc in isolated mitochondria. 25-hydroxycholesterol 0-21 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 129-137 3311719-11 1987 Insulin treatment did not affect P450 SCC activity, whereas IGF-I treatment significantly stimulated P450 SCC activity by 19-36%, as measured by the conversion of 25-hydroxycholesterol to progesterone. 25-hydroxycholesterol 163-184 cytochrome P450 family 11 subfamily A member 1 Homo sapiens 101-109
