摘要:
LPL (lipoprotein lipase) is a rate-limiting enzyme involved in the hydrolysis of triglycerides. Previous studies have shown that microRNA (miR)-467b regulates hepatic LPL expression and plays a role in the progression of steatosis or abnormal lipid retention in obese mice. Macrophage-derived LPL has been shown to promote atherosclerosis. However, if miR-476b influences macrophage LPL expression and the subsequent effects are unknown. Here, we utilized oxLDL-treatment RAW 264.7 macrophages that were transfected with miR-467b mimics or inhibitors...
