Extracellular Vesicle‐Transferred ATP‐Citrate Lyase Induces Monocyte Differentiation Toward Tumor‐Associated Macrophages and Fuels Hepatocellular Carcinoma Progression

Advanced Science, EarlyView.
Hepatocellular carcinoma (HCC)‐derived extracellular vesicles (EVs) enrich the metabolic enzyme ATP‐citrate lyase (ACLY). EV‐transferred ACLY enhances palmitate biosynthesis, increases the S‐palmitoylation and stability of multiple immune checkpoint proteins, augments the cellular immunosuppressive activity, and ultimately accelerates the malignant ...

Plasma oxysterols: Altered level of plasma 24-hydroxycholesterol in patients with bipolar disorder

The Journal of Steroid Biochemistry and Molecular Biology, 2021
Cholesterol and its oxygenated metabolites, including oxysterols, are intensively investigated as potential players in the pathophysiology of brain disorders. Altered oxysterol levels have been described in patients with numerous neuropsychiatric disorders.

Side chain oxidized oxysterols in cerebrospinal fluid and the integrity of blood-brain and blood-cerebrospinal fluid barriers

Journal of Lipid Research, 2003
The side chain oxidized oxysterol 24S-hydroxycholesterol (24-OH-chol) is formed almost exclusively in the brain, and there is a continuous passage of this oxysterol through the circulation to the liver.

Palmitic Acid Promotes Antiviral Innate Immunity via ZDHHC20‐Mediated CMPK2 Palmitoylation

Advanced Science, EarlyView.
Metabolites have important functions in innate immune activation and regulation. Wang et al. uncover metabolic regulation of antiviral immunity through CMPK2 palmitoylation, which regulates CMPK2 mitochondrial localization and is promoted by ZDHHC20 but reversed by PPT1, inhibition of which antagonizes viral infection in mice.

Modulation of Muller cell membrane organization by 24S‐hydroxycholesterol

Acta Ophthalmologica, 2017
PurposeMuller glial cells (MGC) are involved in the retinal homeostasis and they are sustaining cholesterol homeostasis. A lack or an excess of cholesterol in neurons can cause neuro‐degeneration. Cholesterol is eliminated from the retina mainly as 24S‐hydroxycholesterol (24S‐OHC).

Characterization of soticlestat, a novel cholesterol 24-hydroxylase inhibitor, in acute and chronic neurodegeneration models

Neuroscience Research
We investigated whether soticlestat (TAK-935), a newly discovered cholesterol 24-hydroxylase (CH24H) inhibitor now in phase 3 clinical trials for Dravet and Lennox-Gastaut syndromes, has effects on neurodegeneration in both chronic and acute animal ...

Cholesterol‐Mediated Metabolic‐mechanotransductive Crosstalk Orchestrates Castration Resistance in Prostate Cancer

Advanced Science, EarlyView.
Full androgen deprivation (FAD) induces paracrine cholesterol in prostate cancer that drives the polarization of cancer‐associated fibroblasts (CAFs) and subsequent elevated matrix stiffness. Matrix stiffness in turn potentiates tumor cell survival under FAD pressure via dual mechanotransductive activation of the IRE1α‐XBP1s stress‐response axis ...

Pharmacokinetic profiling of imatinib in relation to CYP3A4 activity in leukaemia patients

British Journal of Clinical Pharmacology, EarlyView.
Aim Imatinib pharmacokinetics exhibit large interindividual variability because of differences in CYP3A4 activity—the main imatinib‐metabolizing enzyme. While therapeutic drug monitoring is effective, it requires steady‐state conditions and frequent sampling.

Cholesterol, oxysterol, triglyceride, and coenzyme Q homeostasis in ALS. Evidence against the hypothesis that elevated 27-hydroxycholesterol is a pathogenic factor.

PLoS ONE, 2014
High plasma levels of cholesterol have been suggested to be neuroprotective for the degenerative disease amyotrophic lateral sclerosis (ALS) and to be associated with increased survival time.

Esterification of 4β-hydroxycholesterol and other oxysterols in human plasma occurs independently of LCAT

Journal of Lipid Research, 2020
The acyltransferase LCAT mediates FA esterification of plasma cholesterol. In vitro studies have shown that LCAT also FA-esterifies several oxysterols, but in vivo evidence is lacking. Here, we measured both free and FA-esterified forms of sterols in 206
