Expression of Sterol 27-Hydroxylase (CYP27A1) Enhances Cholesterol Efflux [PDF]
Journal of Biological Chemistry, 2003 Cholesterol efflux from CHOP cells transfected with sterol 27-hydroxylase (CYP27A1) was compared with non-transfected and mock-transfected cells. Transfection caused expression of CYP27A1, formation of 27-hydroxycholesterol, and inhibition of cholesterol biosynthesis. Transfection enhanced cholesterol efflux to apolipoprotein A-I or human plasma by 2-3-

CYP27A1 inhibits bladder cancer cells proliferation by regulating cholesterol homeostasis [PDF]
Cell Cycle, 2018 CYP27A1, an enzyme involved in regulating cellular cholesterol homeostasis, converts cholesterol into 27-hydroxycholesterol (27-HC). The relationship between CYP27A1 and cell proliferation was studied to determine the role of CYP27A1 in bladder cancer. The expression of CYP27A1 in three bladder cancer cell lines (T24, UM-UC-3 and 5637) were assessed by

Enzyme activity assay for cholesterol 27-hydroxylase in mitochondria
Journal of Lipid Research, 2006 Mitochondrial cholesterol 27-hydroxylase (CYP27A1) plays an important role in the maintenance of intracellular cholesterol homeostasis. Cholesterol delivery to the mitochondrial inner membrane is believed to be a rate-limiting step for the “acidic ...

Expression and localization of sterol 27-hydroxylase (CYP27A1) in monkey retina [PDF]
Experimental Eye Research, 2006 Sterol 27-hydroxylase (CYP27A1) is a mitochondrial P-450 enzyme with broad substrate specificity for C27 sterols including 7-ketocholesterol (7kCh). CYP27A1 is widely expressed in human tissues but has not been previously demonstrated in the retina.

A novel CYP27A1 frameshift mutation causing cerebrotendinous xanthomatosis in an Indian family
Annals of Movement Disorders, 2022 Cerebrotendinous xanthomatosis is a rare and underreported lipid storage disorder caused by various mutations in the CYP27A1 gene. Here, we report a novel homozygous mutation in the CYP27A1 gene in an Indian family.

Bile acid homeostasis in female mice deficient in Cyp7a1 and Cyp27a1
Acta Pharmaceutica Sinica B, 2021 Bile acids (BAs) are amphipathic molecules important for metabolism of cholesterol, absorption of lipids and lipid soluble vitamins, bile flow, and regulation of gut microbiome. There are over 30 different BA species known to exist in humans and mice, which are endogenous modulators of at least 6 different membrane or nuclear receptors.
