Cholesterol 25-hydroxylation activity of CYP3A

Journal of Lipid Research, 2011
To date, many studies have been conducted using 25-hydroxycholesterol, which is a potent regulator of lipid metabolism. However, the origins of this oxysterol have not been entirely elucidated. Cholesterol 25-hydroxylase is one of the enzymes responsible

Key regulatory oxysterols in liver: analysis as Δ4-3-ketone derivatives by HPLC and response to physiological perturbations

Journal of Lipid Research, 2001
A number of oxysterols have been implicated in metabolic regulation. Key among these are (24S),25-epoxycholesterol and (24S)-hydroxycholesterol, high affinity ligands for the nuclear transcription factor liver X receptor α; 27-hydroxycholesterol, a bile ...

Plasma advanced glycation end products and soluble receptor for advanced glycation end products as indicators of sterol content in human carotid atherosclerotic plaques

Diabetes & Vascular Disease Research, 2022
Advanced glycation end products (AGEs) are independently related to cardiovascular disease (CVD) and favor cholesterol and oxysterol accumulation in macrophage foam cells.

Hypercholesterolemia-induced Aβ accumulation in rabbit brain is associated with alteration in IGF-1 signaling

Neurobiology of Disease, 2008
Hypercholesterolemia increases levels of β-amyloid (Aβ), a peptide that accumulates in Alzheimer's disease brains. Because cholesterol in the blood does not cross the blood brain barrier (BBB), the link between circulating cholesterol and Aβ accumulation

A Japanese prospective multicenter study of urinary oxysterols in biliary atresia

Scientific Reports, 2021
Diagnosis of biliary atresia (BA) can involve uncertainties. In the present prospective multicenter study, we considered whether urinary oxysterols represent a useful marker for diagnosis of BA in Japanese children.

NCOA4 Accelerates Abdominal Aortic Aneurysm Formation by Regulating Macrophage Activation and Ferroptosis via STAT1–CH25H Axis

Advanced Science, EarlyView.
Under pathological stimulation, NCOA4 in macrophages interacts with STAT1 to promote CH25H transcription. The subsequent increase in 25‐HC production activates macrophages, triggers inflammatory responses and ferroptosis, and accelerates the progression of AAA.

Clinical relevance of pharmacogenomic information for improving prescribing practices in acutely admitted older medical patients

British Journal of Clinical Pharmacology, EarlyView.
Aims Safe prescribing and effective medication review during acute hospitalization depends on accurate information about liver and kidney function because these organs are responsible for the elimination of most medications. While estimates for kidney function are widely used, comparable markers of hepatic drug‐metabolizing capacity are not routinely ...

Sodium Ions Affect GPR17 Conformational States and Functionality

Proteins: Structure, Function, and Bioinformatics, EarlyView.
ABSTRACT Sodium is an allosteric modulator of several class‐A GPCR regulating active versus inactive conformation state and may be a critical issue for the optimization of crystallization procedures. Herein, the role of Na+ in the regulation of GPR17 conformational states was studied through MD simulations of GPR17 wild‐type and mutated on two ...
