7alpha-hydroxylated bile acids from oxysterols requires an oxysterol 7alpha-hydroxylase encoded by the Cyp7b1 locus. As expected, mice deficient in this enzyme have elevated plasma and tissue levels of 25- and 27-hydroxycholesterol; however, levels of another major oxysterol, 24-hydroxycholesterol, are not increased in these mice, suggesting the presence of another oxysterol 7alpha-hydroxylase. Here, we describe
