27-hydroxycholesterol (27-HC) is synthesized by cholesterol under the action of sterol 27-hydroxylase in the liver. It is an abundant oxidizing sterol in the cyclic range of 0.15 to 0.73 μM. 27-HC is a substrate for bile synthesis
Product description:
27-Hydroxycholesterol, an oxysterol secreted from macrophages, has been shown to be capable of passing through the blood-brain barrier and entering the circulation via the brain. This compound has been shown to be a cholesterol oxidation metabolite that causes an increase in levels of GADD 153 and caspase-12 in ARPE-19 cells in vitro. 27-Hydroxycholesterol has also been reported to increase levels of Aβ peptide production, reduce mitochondrial membrane potential, and induce nuclear factor κB (NFκB) and heme-oxygenase 1 (HO-1). Overall, 27-Hydroxycholesterol displays apoptotic properties via reactive oxygen species (ROS) generation, glutathione depletion, and inflammation. 27-Hydroxycholesterol is an activator of LXR α and LXR β. An oxysterol with cholesterol oxidation metabolite properties.
Application:
To observe its inhibitory effect on lipid accumulation in liver. As a liver X receptor (LXR) ligand in breast cancer cell lines; As a control in liquid chromatography-tandem mass spectrometry (LC-MS-MS), 25-OHC in jejunum samples was quantified
