Általános leírás

7β-hydroxycholesterol (7β-OHC) is an oxysterol synthesized by the oxidation of the low-density lipoprotein (LDL). It is primarily catabolized to bile acid in the liver.

Alkalmazás

7β-hydroxycholesterol has been used:
  • as an internal oxysterol standard in liquid chromatography–mass spectrometry (LC-MS) for the quantification of sterols associated with cholesterol biosynthesis in neurospheres post inhibitor AY9944 treatment
  • to reconstitute high-density lipoprotein (HDL) for anti-apoptotic studies in insulinoma cell line INS1e
  • as a cholesterol oxidation product standard in ultra high-performance liquid chromatography (UHPLC) coupled with high- resolution quadrupole time-of-flight (Q-TOF) mass spectrometry

Biokémiai/fiziológiai hatások

7β-hydroxycholesterol (7β-OHC) favors apoptosis via caspase 8 based mitochondrial pathway. It also hinders cancer cell survival by generating reactive oxygen species(ROS). The levels of 7β-OHC are elevated in the cerebrospinal fluid of multiple sclerosis and Alzheimer′s disease (AD) patients. 7β-OHC also promotes oxiapoptophagy and demyelination. It activates mitogen-activated protein kinases and modulates intracellular Ca2+ homeostasis and may contribute to the disorganization of Golgi and endoplasmic reticulum membranes.

Some oxysterols resulting either from enzymatic oxidation or autoxidation of cholesterol are associated with age-related diseases including neurodegenerative diseases. Among these oxysterols, 7β-hydroxycholesterol (7β-OHC) is often found at increased levels in patients. It is therefore important to identify molecules or

In the present study, we characterize the early cytotoxic effects of 7beta-hydroxycholesterol, a major cytotoxin in oxidized LDL, in human aortic smooth muscle cells. Within a few minutes after addition, 7beta-hydroxycholesterol induced Ca(2+) oscillations with a frequency of approximately 0.3-0.4

The cytotoxic activity of 7beta-hydroxycholesterol (7beta-OHC) was evaluated on human NCI-H460 lung cancer cells. 7beta-OHC decreased clonogenic survival of NCI-H460 in a dose dependent pattern. 7beta-OHC induced apoptosis in NCI-H460, with the characteristic features like increase in sub-G(1) hypodiploid (apoptotic)

The induction of apoptosis in cells of the arterial wall is a critical event in the development of atheroma. 7beta-Hydroxycholesterol (7beta-OH) and cholesterol-5beta,6beta-epoxide (beta-epoxide) are components of oxLDL and have previously been shown to be potent inducers of apoptosis. However

Cholesterol is one of the major structural constituents in a liposomal bilayer. Cholesterol is susceptible to various reactions in the presence of oxygen, heat, light, certain metals, and radicals during manufacturing or storage, which may cause to generate cholesterol oxidation
