Analysis of the Expression of Lipid Metabolism-Related Proteins (LDLR and ABCG1) in Vascular Wall Cells in Hyperlipidaemia

Hyperlipidemia is a critical condition characterized by elevated levels of lipids, including cholesterol and triglycerides, in the blood. This condition significantly contributes to the development of atherosclerosis and other cardiovascular diseases by influencing lipid metabolism in vascular wall cells. Lipid metabolism-related proteins such as Low-Density Lipoprotein Receptor (LDLR) and ATP-Binding Cassette Subfamily G Member 1 (ABCG1) play a pivotal role in regulating lipid homeostasis within these cells. LDLR is responsible for the uptake of low-density lipoproteins (LDL) from the blood, while ABCG1 is involved in the efflux of cholesterol from cells to high-density lipoproteins (HDL), thus maintaining cellular cholesterol balance. This paper aims to analyze the expression of LDLR and ABCG1 in vascular wall cells in the context of hyperlipidemia, focusing on their roles in lipid metabolism and their implications for atherosclerosis. The review will explore molecular mechanisms regulating the expression of these proteins, their interactions with other metabolic pathways, and their potential as therapeutic targets in treating hyperlipidemia and preventing cardiovascular disease. The findings underscore the complex interplay between lipid metabolism and vascular health and highlight the potential for modulating lipid metabolism-related proteins to mitigate the effects of hyperlipidemia.
