1 Plasma and tissue levels of 25- and 27-hydroxycholesterol, two oxysterol substrates of this enzyme with potent regulatory actions in cultured cells, were markedly elevated in Cyp7b1(-/-) knockout animals. Hydroxycholesterols cytochrome P450, family 7, subfamily b, polypeptide 1 Mus musculus
2 Plasma and tissue levels of 25- and 27-hydroxycholesterol, two oxysterol substrates of this enzyme with potent regulatory actions in cultured cells, were markedly elevated in Cyp7b1(-/-) knockout animals. Oxysterols cytochrome P450, family 7, subfamily b, polypeptide 1 Mus musculus
3 We conclude that the major physiological role of the CYP7B1 oxysterol 7alpha-hydroxylase is to metabolize 25- and 27-hydroxycholesterol and that loss of this enzyme in the liver is compensated for by increases in the synthesis of bile acids by other pathways. 25- and 27-hydroxycholesterol cytochrome P450, family 7, subfamily b, polypeptide 1 Mus musculus
4 We conclude that the major physiological role of the CYP7B1 oxysterol 7alpha-hydroxylase is to metabolize 25- and 27-hydroxycholesterol and that loss of this enzyme in the liver is compensated for by increases in the synthesis of bile acids by other pathways. 25- and 27-hydroxycholesterol cytochrome P450, family 7, subfamily b, polypeptide 1 Mus musculus
