General description

27-hydroxycholesterol (27-HC) is synthesized from cholesterol by the action of sterol 27-hydroxylase in liver. It is an abundant oxysterol in the circulation ranging from 0.15 to 0.73 μM. 27-HC serves as a substrate for bile synthesis.

Application

27-hydroxycholesterol has been used:
  • to test its inhibitory effect on hepatic lipid accumulation
  • as liver X receptor (LXR) ligand in breast cancer cell lines
  • as a control in liquid chromatography with tandem mass spectrometry (LC-MS-MS) for the quantitation of 25-OHC in jejunum samples

Biochem/physiol Actions

27-hydroxycholesterol (27-HC) is a weak liver X receptor (LXR) agonist and a selective estrogen receptor modulator (SERM). Elevated levels of 27-HC is observed in hypercholesterolemia. 27-HC is implicated in breast cancer tumor and glioblastoma progression. 27-HC may help in treating non-alcoholic steatohepatitis. Elevated levels of 27-HC is associated with atherosclerotic lesions.

Menopausal hormone therapy (MHT) increases the risk of coronary heart disease (CHD) in older women with elevated low-density lipoprotein (LDLC) levels. The endogenous estrogen receptor antagonist 27-hydroxycholesterol (27OHC) is correlated with LDLC levels and may block the beneficial effects of

HDL is considered the most important mechanism for the excretion of intracellular cholesterol. The liver is the only organ capable to metabolize cholesterol into bile acid. The enzymatic conversion of cholesterol to bile acid is dependent on the cytochrome P450

Secretion of 27-hydroxycholesterol (27OHC) from macrophages is considered as an alternative to HDL-mediated reverse transport of excess cholesterol. We investigated 27OHC-concentrations in plasma of humans and mice with monogenic disorders of HDL metabolism. As compared to family controls mutations in

To date, estrogen is the only known endogenous estrogen receptor (ER) ligand that promotes ER+ breast tumor growth. We report that the cholesterol metabolite 27-hydroxycholesterol (27HC) stimulates MCF-7 cell xenograft growth in mice. More importantly, in ER+ breast cancer patients

Side chain oxidized oxysterols have a unique ability to traverse lipophilic membranes. We tested the hypothesis that there is a net flux of 27-hydroxycholesterol from the circulation into the brain using plasma samples collected from the internal jugular vein and
