1.14.99.38 malfunction decitabine-induced hypomethylation of the cholesterol 25-hydroxylase gene is responsible for cell death of myelodysplasia/leukemia cells 746440 1.14.99.38 malfunction loss of function of Ch25h leads to susceptibility to viral infections in vitro 727611 1.14.99.38 malfunction mice with a disruption in the cholesterol 25-hydroxylase gene regulate cholesterol metabolism normally. Ch25h-/- mice have higher levels of mRNAs coding for immunoglobulin A and immunoglobulin J. Disruption in the Cyp7b1 gene leads to significantly increased levels of 25-hydroxycholesterol in the circulation, and to significantly lower levels of IgA compared to wild-type mice 727109 1.14.99.38 malfunction patients with hereditary spastic paresis, a rare inherited disease with mutations in the CYP7B1 gene, have highly elevated levels of 25- and 27-hydroxycholesterol but normal levels of cholesterol and bile acids 727109 1.14.99.38 additional information 25-hydroxycholesterol does not stimulate the sPLA2-IIA promoter in the mouse Schwann cell line MSC80 727109 1.14.99.38 additional information Ch25h expression is controlled primarily by type I IFN signaling, type1 IFN-mediated Ch25h expression is IFNR-dependent, overview -, 715833 1.14.99.38 additional information the high concentrations of vitamin D3 metabolites required for upregulation of the cholesterol 25-hydroxylase gene makes it unlikely that these metabolites are important regulators of cholesterol 25-hydroxylase in vivo 727109 1.14.99.38 physiological function adenovirus-mediated enzyme overexpression in mice improves glucose tolerance and insulin sensitivity and lowers the homeostatic model assessment for insulin resistance score 745450 1.14.99.38 physiological function cholesterol 25-hydroxylase acts as a host restriction factor on pseudorabies virus replication 745479 1.14.99.38 physiological function cholesterol 25-hydroxylase inhibits porcine reproductive and respiratory syndrome virus replication 745658
