The use of [7α-3H]- and [7α, 7β-3H]cholesterol in the enzymic assay of cholesterol 7α-hydroxylase

Journal of Lipid Research, 1976
A tritium release method is described for following the enzymic conversion of cholesterol to 7α-hydroxycholesterol. Incubations of rat liver subcellular preparations (containing microsomes) with [7α-3H]cholesterol or [7α,7β-3H]cholesterol release the ...

Age-associated alterations in cholesterol homeostasis: evidence from a cross-sectional study in a Northern Italy population. [PDF]

, 2014
BACKGROUND: The modifications of cholesterol metabolism associated with aging are ill-defined. The objective of this study was to define age-associated alterations of the different metabolic pathways controlling cholesterol homeostasis by analyzing ...

Determination of hepatic cholesterol 7α-hydroxylase activity in man

Journal of Lipid Research, 1974
Methods were developed to determine the activity of the microsomal enzyme cholesterol 7α-hydroxylase in human liver. The enzyme assay could be performed with as little as 20 mg of fresh liver tissue, thus making the procedure applicable to specimens ...

Gender Differences in Bile Acids and Microbiota in Relationship with Gender Dissimilarity in Steatosis Induced by Diet and FXR Inactivation. [PDF]

, 2017
This study aims to uncover how specific bacteria and bile acids (BAs) contribute to steatosis induced by diet and farnesoid X receptor (FXR) deficiency in both genders.

The Regulatory Role of Iron Transporter SLC39A13 in Liver Fibrosis

Advanced Science, EarlyView.
SLC39A13/ZIP13, a newly discovered intracellular iron transporter, delivers iron to the ER/Golgi to catalyze procollagen hydroxylation during collagen maturation. Here, we systematically characterize the cell type‐specific functions of ZIP13 across distinct hepatic cell populations, and identify hepatic stellate cell‐specific ZIP13 as a promising and ...

25R,26-Hydroxycholesterol revisited: synthesis, metabolism, and biologic roles

Journal of Lipid Research, 2002
The CYP27 gene is expressed in arterial endothelium, macrophages, and other tissues. The gene product generates sterol intermediates that function as ligands for nuclear receptors prior to their transport to the liver for metabolism, mostly to bile acids.

Regulation of 3β-Hydroxysteroid Dehydrogenase/∆5-∆4 Isomerase: A Review [PDF]

, 2013
This review focuses on the expression and regulation of 3β-hydroxysteroi ddehydrogenase/Δ5-Δ4 isomerase (3β-HSD), with emphasis on the porcine version. 3β-HSD is often associated with steroidogenesis, but its function in the metabolism of both steroids ...

Delayed diagnosis of 3β‐HSD7 deficiency in adolescence: Two case reports and review of the literature

JPGN Reports, EarlyView.
ABSTRACT Congenital bile acid synthesis defects (BASD), the most common of which is 3β‐hydroxy‐Δ5‐C27‐steroid dehydrogenase oxidoreductase (3β‐HSD7) deficiency, are a rare cause of fat‐soluble vitamin malabsorption. We describe a 14‐year‐old girl who presented at 14 months with a left distal femur fracture and failure to thrive.

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.

From HBV to MASLD Cirrhosis: Mechanistic Insights and Therapeutic Strategies

Portal Hypertension &Cirrhosis, EarlyView.
This review examines the epidemiological shift from hepatitis B virus (HBV) to metabolic dysfunction‐associated steatotic liver disease (MASLD) as the leading cause of cirrhosis globally. It highlights the distinct pathogenic mechanisms between HBV and MASLD cirrhosis and discusses evolving diagnostic tools and therapeutic strategies tailored to the ...
