Plasma levels of 24S-hydroxycholesterol in patients with neurological diseases

, 2000
The brain is the exclusive or almost exclusive site of formation of 24S-hydroxycholesterol and we have shown that the circulating level of 24S-hydroxycholesterol is dependent upon the relation between cerebral production and hepatic clearance.

Epigenomic Cascades Across Organs in Metabolic Dysfunction–Associated Steatotic Liver Disease: New Therapeutic Horizons

Obesity Reviews, EarlyView.
ABSTRACT Metabolic dysfunction–associated steatotic liver disease (MASLD) is the most common chronic liver disorder worldwide, affecting approximately one‐third of the population and increasing the risk of severe hepatic and cardiovascular complications.

In vivo formation of 25-hydroxycholesterol from endogenous cholesterol after a single meal, dietary cholesterol challenge.

Journal of Lipid Research, 1994
The role of oxysterols as regulatory molecules in the suppression of 3-hydroxy-3-methylglutaryl coenzyme A (HMG-CoA) reductase activity was investigated in the intact rat in response to an acute dietary cholesterol challenge.

Leptin–cholesterol crosstalk in pregnancy: Mechanistic implications for placental function and cardiometabolic programming

Experimental Physiology, EarlyView.
Abstract Pregnancy requires the coordinated maternal reorganization of lipid and endocrine pathways to sustain fetal growth and anticipate neonatal nutrition. Leptin, produced by adipose tissue and the placenta, acts as an integrative signal linking maternal energy status with trophoblast function and vascular adaptation, while cholesterol provides ...

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.

Plasma 4β-Hydroxycholesterol: An Endogenous CYP3A Metric? [PDF]

Clinical Pharmacology & Therapeutics, 2009
We assessed the suitability of 4beta-hydroxycholesterol (4betaOH-C) as an endogenous cytochrome P450 3A (CYP3A) phenotyping metric. 4betaOH-C and its ratio to cholesterol (4betaOH-C/C) were determined in five cocktail phenotyping studies, with and without co-medication with a potential CYP3A inhibitor.

Oxysterols in the circulation of patients with the Smith-Lemli-Opitz syndrome: abnormal levels of 24S- and 27-hydroxycholesterol

Journal of Lipid Research, 2001
Infants with the cholesterol synthesis defect Smith-Lemli-Opitz syndrome (SLO) have reduced activity of the enzyme 7-dehydrocholesterol-7-reductase and accumulate 7-dehydrocholesterol, with the highest concentration in the brain.

Orchestrating the metastatic symphony: the role of extracellular vesicles in the epithelial–mesenchymal transition and pulmonary niche formation of breast cancer

Biological Reviews, Volume 101, Issue 5, Page 2103-2118, October 2026.
ABSTRACT The complexity of breast cancer (BC) lung metastasis lies in the capacity of tumour cells to interact efficiently with distant organs to promote colonisation, a process that involves the sophisticated coordination of inherent cellular plasticity and the remodelling of the distant microenvironment.

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 ...
