Assay method for mitochondrial sterol 27-hydroxylase with 7α-hydroxy-4-cholesten-3-one as a substrate in the rat liver

Journal of Lipid Research, 2003
Mitochondrial sterol 27-hydroxylase (EC 1.14.13.15) is an important enzyme, not only in the formation of bile acids from cholesterol intermediates in the liver but also in the removal of cholesterol by side chain hydroxylation in extrahepatic tissues ...

Reduced Plasma Levels of 25-Hydroxycholesterol and Increased Cerebrospinal Fluid Levels of Bile Acid Precursors in Multiple Sclerosis Patients [PDF]

, 2016
Multiple sclerosis (MS) is an autoimmune, inflammatory disease of the central nervous system (CNS). We have measured the levels of over 20 non-esterified sterols in plasma and cerebrospinal fluid (CSF) from patients suffering from MS, inflammatory CNS ...

Nerve Ultrasound Detects Peripheral Nerve Enlargement in Cerebrotendinous Xanthomatosis

Muscle &Nerve, Volume 73, Issue 6, Page 1082-1088, June 2026.
ABSTRACT Introduction/Aims Cerebrotendinous xanthomatosis (CTX) is a rare autosomal recessive disorder caused by variants in the CYP27A1 gene, resulting in cholestanol accumulation in various tissues, including peripheral nerves. Polyneuropathy is common but often under‐recognized in CTX.

Cholesterol and 27-hydroxycholesterol 7 alpha-hydroxylation: evidence for two different enzymes.

Journal of Lipid Research, 1993
The use of 2-hydroxypropyl-beta-cyclodextrin as a vehicle for solubilizing cholesterol and 27-hydroxycholesterol has led to a study of their rates of 7 alpha-hydroxylation in microsomal preparations from hamster liver and HepG2 cells.

A Rare Case of Cerebrotendinous Xanthomatosis Associated With a Mutation on COG8 Gene

Journal of Investigative Medicine High Impact Case Reports, 2023
Cerebrotendinous xanthomatosis ( CTX ) is a rare hereditary disease described by a mutation in the CYP27A1 gene , which encodes the sterol 27-hydroxylase enzyme involved in the synthesis of bile acid.

The proteomic differences and expression of fatty acid‐binding protein 6 (FABP6) associated with gastrointestinal injury in horses with oral administration of a clinical dose of phenylbutazone

Equine Veterinary Journal, Volume 58, Issue 3, Page 845-856, May 2026.
Abstract Background Phenylbutazone (PBZ) can potentially induce gastrointestinal ulceration, and early detection of PBZ‐induced gastroenteropathy will be useful for the diagnosis, treatment, and prevention of PBZ toxicity. Objectives To identify putative proteins associated with equine gastric ulcer syndrome after clinical dose (4.4 mg/kg ...

Two new mutations in the sterol 27-hydroxylase gene in two families lead to cerebrotendinous xanthomatosis [PDF]

Human Genetics, 1996
This report concerns two new mutations in the sterol 27-hydroxylase gene in two patients with cerebrotendinous xanthomatosis (CTX). In a Surinam-Creole patient (patient A), a G deletion on position cDNA 546/547 in exon 3 led to a frameshift and the introduction of a premature termination codon.

High cholesterol absorption efficiency interferes with bile acid metabolism and cholesterol elimination from the body

Journal of Internal Medicine, Volume 299, Issue 5, Page 628-638, May 2026.
Abstract Background Elevated low‐density lipoprotein (LDL) cholesterol causes atherosclerotic cardiovascular diseases. Variables of whole‐body cholesterol metabolism, for example, high cholesterol absorption efficiency, might also be atherogenic, whereas the role of bile acids is controversial.
