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

There is a significant flux of the neurotoxic oxysterol 27-hydroxycholesterol (27OHC) from the circulation across the blood-brain barrier. Because there is a correlation between 27OHC and cholesterol in the circulation and lipoprotein-bound cholesterol does not pass the blood-brain barrier, we

Th1 lymphocytes are predominant in atherosclerotic lesions. However, mechanisms involved in the Th1 predominance are unknown. We have investigated the possibility of Th1 lymphocyte recruitment in a cholesterol-rich milieu. A high cholesterol diet resulted in enhanced expression of CCR5 ligands

Enhanced production of TNF-α from macrophages promotes development and instability of atherosclerotic plaques, but involvement of lipid component in TNF-α production has not been clarified in atherosclerosis. We attempted to determine whether cholesterol oxidation products (oxysterols) could modify TNF-α production.
