| Common Name | 8(R)-Hydroperoxylinoleic acid |
|---|
| Description | 8(R)-hydroperoxylinoleic acid (8(R)-EPODE) is an oxidized product of linoleic acid. Oxidized lipids such as 8(R)-HPODE can decrease cellular proteoglycan metabolism in endothelial monolayers and alter mRNA levels of major specific proteoglycans in a concentration-dependent manner. This may have implications in lipid-mediated disruption of endothelial barrier function and atherosclerosis. (PMID: 8645361 , 9507987 ). |
