2 Novel deletions of the sterol 27-hydroxylase gene in a Chinese Family with Cerebrotendinous Xanthomatosis [PDF]

BMC Neurology, 2011
Background Cerebrotendinous xanthomatosis (CTX) is a rare lipid-storage disease. We investigated the clinic manifestation, histopathology and sterol 27-hydroxylase gene (CYP27A1) in a Chinese family with Cerebrotendinous Xanthomatosis (CTX).

Sterol 27-Hydroxylase Deficiency as a Cause of Neonatal Cholestasis: Report of 2 Cases and Review of the Literature [PDF]

Frontiers in Pediatrics, 2021
Introduction: Inborn errors of primary bile acid (BA) synthesis are rare autosomal recessive disorders responsible for 1–2% of cases of neonatal cholestasis.

Sterol 27-hydroxylase: expression in human arterial endothelium

Journal of Lipid Research, 1997
Human endothelium obtained from both the aorta and the pulmonary artery has been evaluated for the presence of the messenger RNA coding for the expression of sterol 27-hydroxylase.

Sterol 27-hydroxylase gene dosage and the antiatherosclerotic effect of Rifampicin in mice. [PDF]

Biosci Rep, 2018
Sterol 27-hydroxylase (CYP27A1) catalyzes the hydroxylation of cholesterol to 27-hydroxycholesterol (27-OHC) and regulates cholesterol homeostasis. In Cyp27a1/ Apolipoprotein E (ApoE) double knockout (KO) mice fed with Western diet (WD), the atherosclerotic phenotype found in ApoE KO mice was reversed.

Sterol 27-hydroxylase: high levels of activity in vascular endothelium.

Journal of Lipid Research, 1994
Sterol 27-hydroxylase activity in bovine aortic endothelial (BAE) cells in culture has been compared with that in HepG2 cells and in Chinese hamster ovary (CHO) cells using identical culture conditions. The total enzyme activity of BAE cells (3.0 nmol/72

Expression and localization of sterol 27-hydroxylase (CYP27A1) in monkey retina. [PDF]

Exp Eye Res, 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.

Bile Acid Homeostasis in a Cholesterol 7α-Hydroxylase and Sterol 27-Hydroxylase Double Knockout Mouse Model. [PDF]

Hepatology, 2019
Bile acids (BAs) are diverse molecules that are synthesized from cholesterol in the liver. The synthesis of BAs has traditionally been shown to occur through two pathways. Cholesterol 7α‐hydroxylase (CYP7A1) performs the initial and rate‐limiting step in the classical pathway, and sterol 27‐hydroxylase (CYP27A1) initiates the hydroxylation of ...

Beyond bile acids synthesis: metabolomics profiling highlights extensive metabolic dysregulation and treatment response in CTX [PDF]

Orphanet Journal of Rare Diseases
Background Cerebrotendinous xanthomatosis (CTX) is an inherited metabolic disorder caused by variants in CYP27A1 leading to loss of sterol-27-hydroxylase activity.

Hormonal regulation of the human sterol 27-hydroxylase gene CYP27A1. [PDF]

Biochem J, 2003
The mitochondrial sterol 27-hydroxylase (CYP27A1) is a multifunctional cytochrome P450 enzyme that catalyses important hydroxylations in the biosynthesis of bile acids and bioactivation of vitamin D3.

A novel mutation in the sterol 27-hydroxylase gene of a woman with autosomal recessive cerebrotendinous xanthomatosis [PDF]

Orphanet Journal of Rare Diseases, 2010
Article abstract Mutations of the gene encoding the mitochondrial enzyme sterol 27-hydroxylase (CYP27A1 gene) cause defects in the cholesterol pathway to bile acids that lead to the storage of cholestanol and cholesterol in tendons, lenses and the ...
