Insulin suppresses bile acid synthesis in cultured rat hepatocytes by down-regulation of cholesterol 7α-hydroxylase and sterol 27-hydroxylase gene transcription

, 1995
Evidence from in vivo studies indicates that the bile acid pool and bile acid excretion are increased in humans with diabetes mellitus and in experimental diabetic animals, and that both parameters return to normal levels after administration of insulin.

Effect of increasing the expression of cholesterol transporters (StAR, MLN64, and SCP-2) on bile acid synthesis

Journal of Lipid Research, 2004
There are two major pathways of bile acid synthesis: the “neutral” pathway, initiated by highly regulated microsomal cholesterol 7α-hydroxylase (CYP7A1), and an “alternative” pathway, initiated by mitochondrial sterol 27-hydroxylase (CYP27A1).

Phenotypic characterization of Lith genes that determine susceptibility to cholesterol cholelithiasis in inbred mice: integrated activities of hepatic lipid regulatory enzymes1

Journal of Lipid Research, 1999
There is no consensus whether hepatic lipid regulatory enzymes play primary or secondary roles in cholesterol cholelithiasis. We have used inbred mice with Lith genes that determine cholesterol gallstone susceptibility to evaluate the question.

Anti‐hypercholesterolemic effects of barley and its role in the management of metabolic disorders: A comprehensive review

JSFA reports, EarlyView.
Abstract The dietary and lifestyle practices have predominantly compromised human health, which are influenced by modernization and industrialization. Hypercholesterolemia, caused by the consumption of fatty and fried foods and a sedentary lifestyle, is a major modifiable risk factor for cardiovascular disease and commonly coexists with obesity ...

Cerebrotendinous xanthomatosis: report of two Brazilian brothers Xantomatose cerebrotendínea: relato de dois irmãos brasileiros

Arquivos de Neuro-Psiquiatria, 2004
Cerebrotendinous xanthomatosis is a treatable rare autossomal recessive disease characterized by lipid storage secondary to a sterol 27-hydroxylase deficiency in the formation of cholic and chenodeoxycholic acids.

Downregulation of Cyp7a1 by Cholic Acid and Chenodeoxycholic Acid in Cyp27a1/ApoE Double Knockout Mice: Differential Cardiovascular Outcome

Frontiers in Endocrinology, 2020
Sterol 27-hydroxylase (CYP27A1) is a key enzyme in bile acids (BAs) biosynthesis and a regulator of cholesterol metabolism. Cyp27a1/Apolipoprotein E double knockout (DKO) mice fed with western diet (WD) are protected from atherosclerosis via up ...

Therapeutic potential of okra (Abelmoschus esculentus) in dysglycaemia and metabolic dysfunction: A systematic review and meta‐analysis across the diabetes spectrum

Experimental Physiology, EarlyView.
Abstract The aim of this systematic review and meta‐analysis was to evaluate comprehensively the therapeutic potential of Abelmoschus esculentus (okra) supplementation across the diabetes spectrum of key metabolic risk factors. A search was conducted in PubMed, Scopus, Web of Science, EMBASE and the Cochrane Library, up to 23 July 2025, to identify ...

Differential effects of 17α-ethinylestradiol on the neutral and acidic pathways of bile salt synthesis in the rat

Journal of Lipid Research, 1999
Effects of 17α-ethinylestradiol (EE) on the neutral and acidic biosynthetic pathways of bile salt (BS) synthesis were evaluated in rats with an intact enterohepatic circulation and in rats with long-term bile diversion to induce BS synthesis.

Cholesterol 25‐Hydroxylase Deficiency Provides an Optimal and Durable Protective T Helper 1 Immunity via Interleukin‐12–Interleukin‐2 Axis in BCG‐Vaccinated Mice

MedComm, Volume 7, Issue 10, October 2026.
CH25H deficiency permits optimal dendritic cell activation following BCG exposure, characterized by increased IL‐12p70 production. In vivo, CH25H deficiency promotes enhanced BCG‐mediated protection and sustained IL‐2 producing T cell response. ABSTRACT Bacillus Calmette‐Guérin (BCG) remains the only licensed vaccine for tuberculosis (TB), yet its ...

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 ...
