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.

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.

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
