Exon skipping in the sterol 27-hydroxylase gene leads to cerebrotendinous xanthomatosis [PDF]
We report a new mutation in the sterol 27-hydroxylase (CYP 27) gene in a Dutch family with cerebrotendinous xanthomatosis: a G-->A transition in the splice donor site in intron 4. This mutation leads to skipping of exon 4, resulting in a loss of 66 amino acids in the CYP 27 enzyme molecule.

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

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

Beyond bile acids synthesis: metabolomics profiling highlights extensive metabolic dysregulation and treatment response in CTX [PDF]
Background Cerebrotendinous xanthomatosis (CTX) is an inherited metabolic disorder caused by variants in CYP27A1 leading to loss of sterol-27-hydroxylase activity.

Heterogeneous expression of cholesterol 7 alpha-hydroxylase and sterol 27-hydroxylase genes in the rat liver lobulus. [PDF]
We investigated the lobular localization and molecular level of expression of cholesterol 7 alpha-hydroxylase and sterol 27-hydroxylase, two key enzymes in bile acid synthesis, in isolated periportal and pericentral hepatocytes and by in situ hybridization of rat liver.

Studies on sterol 27-hydroxylase (CYP27A1)
Human sterol 27-hydroxylase (CYP27A1) has been studied in the present thesis with focus on substrate specificity and possible role of the enzyme for prevention of accumulation of cholesterol and cholestanol in tissues. Attempts have been made to evaluate a metabolic pathway to bile acids in human primary hepatocytes that starts with a 27-hydroxylation ...

On the mechanism of accumulation of cholestanol in the brain of mice with a disruption of sterol 27-hydroxylase. [PDF]
The rare disease cerebrotendinous xanthomatosis (CTX) is due to a lack of sterol 27-hydroxylase (CYP27A1) and is characterized by cholestanol-containing xanthomas in brain and tendons. Mice with the same defect do not develop xanthomas. The driving force in the development of the xanthomas is likely to be conversion of a bile acid precursor into ...
