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

British Journal of Clinical Pharmacology, Volume 92, Issue 10, Page 3375-3386, October 2026.
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.

Studies on the oxysterols 4alpha- and 4beta-hydroxycholesterol

, 2011
Cytochrome P450 (CYP) enzymes catalyze the metabolism of both foreign and endogenous substances such as drugs and steroids. Enzymes in subfamily CYP3A sum up to 30% of the total CYP content in the liver and metabolize about 50% of all drugs.

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.

Regulation of caveolin and caveolae by cholesterol in MDCK cells

Journal of Lipid Research, 1998
We have examined the expression of caveolin in MDCK cells under conditions that vary cellular cholesterol concentration. Caveolin mRNA levels dropped to one-sixth of control levels after treatment with simvastatin, an inhibitor of cholesterol 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 ...

Amplification of the gene for SCAP, coupled with Insig-1 deficiency, confers sterol resistance in mutant Chinese hamster ovary cells

Journal of Lipid Research, 2007
The endoplasmic reticulum membrane proteins Insig-1 and Insig-2 limit cholesterol synthesis, in part through their sterol-dependent binding to sterol-regulatory element binding protein (SREBP) cleavage-activating protein (SCAP).

25-Hydroxycholesterol is involved in the pathogenesis of amyotrophic lateral sclerosis

Oncotarget, 2017
This study aimed to evaluate the levels of three major hydroxycholesterols (24-, 25-, and 27-hydroxycholesterols) in the serum and cerebrospinal fluid (CSF) of patients with amyotrophic lateral sclerosis (ALS), as well as to show their role in the pathogenesis of ALS experimental models.

Myelin Impairment and Regeneration in the Central Nervous System: Molecular Mechanisms, Diseases, and Prospective Therapeutic Targets

MedComm, Volume 7, Issue 10, October 2026.
Proper myelin formation is crucial for normal neural circuit function, while myelin deficiency can lead to neural circuit dysfunction and cognitive decline, notably in Alzheimer's disease and other central nervous system demyelinating disorders. This review summarizes central myelin's structure and function, demyelination biomarkers and pathological ...

25-hydroxycholesterol impairs neuronal and muscular development in zebrafish

NeuroToxicology, 2019
Oxysterols have essential effects on brain homeostasis and their levels are often altered in neurodegenerative and neuroinflammatory diseases. Several studies have demonstrated the cytotoxic effects of 25-HC on different cell lines, however, not much is known about its effects on neurons in vivo. In this study, we examined the effects of 25-HC exposure

Reciprocal control of viral infection and phosphoinositide dynamics

FEBS Letters, Volume 600, Issue 17, Page 2526-2546, September 2026.
Phosphoinositides, although scarce, regulate key cellular processes, including membrane dynamics and signaling. Viruses exploit these lipids to support their entry, replication, assembly, and egress. The central role of phosphoinositides in infection highlights phosphoinositide metabolism as a promising antiviral target.
