On the substrate specificity of human CYP27A1
The mitochondrial sterol 27-hydroxylase (CYP27A1) is required for degradation of the C27-sterol side chain in bile acid biosynthesis. CYP27A1 seems, however, to have roles beyond this, as illustrated by patients with a deficient sterol 27-hydroxylase due

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

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 ...

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

The recognition that the 7 alpha-hydroxylation of 27-hydroxycholesterol is catalyzed by an enzyme that is different from cholesterol 7 alpha-hydroxylase raises the question as to the number of similar enzymes that may be present in liver and subserve ...

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 ...

Simultaneous determination of oxysterols, cholesterol and 25-hydroxy-vitamin D3 in human plasma by LC-UV-MS. [PDF]
Oxysterols are promising biomarkers of neurodegenerative diseases that are linked with cholesterol and vitamin D metabolism. There is an unmet need for methods capable of sensitive, and simultaneous quantitation of multiple oxysterols, vitamin D and ...

Reciprocal control of viral infection and phosphoinositide dynamics
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.
