General description

25-hydroxycholesterol (25HC) is synthesized from cholesterol in the presence of oxygen and enzyme cholesterol 25-hydroxylase and the conversion is dependent on nicotinamide adenine dinucleotide phosphate (NADPH) during toll-like receptor activation. 25HC is catabolized to 7α-hydroxylated sterol. 25-hydroxycholesterol-d6 is the deuterated form of 25-hydroxycholesterol.

Application

25-hydroxycholesterol-d6 has been used as an internal standard:
  • in the quantification of 25-OHC in jejunum samples by liquid chromatography with tandem mass spectrometry (LC-MS-MS)
  • in plasma samples by liquid chromatography-mass spectrometry analysis
  • for calibration curve generation for plasma oxysterol quantification

Biochem/physiol Actions

25-hydroxycholesterol is a liver X receptor ligand. This bioactive lipid regulates immune response and macrophages production from monocytes. 25-HC serves as an antiviral effector and may have therapeutic potential. It reduces cholesterol biosynthesis by inactivating sterol regulatory element binding protein and inhibits HMG-CoA reductase (HMGCR). 25-HC may play a protective role in myocardial ischemia-reperfusion injury by inhibiting apoptosis and regulating mitogen-activated protein kinase (MAPK) pathway.

Cholesterol 25-hydroxylase (CH25H) catalyzes the production of 25-hydroxycholesterol (25-HC), an oxysterol that can play an important role in different biological processes. However, the mechanisms regulating CH25H expression have not been fully elucidated. In this study, we determined that CH25H is
