Human coronary smooth muscle cells internalize versican-modified LDL through LDL receptor-related protein and LDL receptors.
Versican-like proteoglycans are the main component of the intimal extracellular matrix interacting with low density lipoprotein (LDL). The aim of this study has been to investigate the receptors involved in versican-modified LDL uptake by human vascular smooth muscle cells (VSMCs). We have found that versican-LDL interaction leads to the following: (1) monomeric LDL particles that are similar i...
متن کاملLDL receptor-related protein mediates uptake of aggregated LDL in human vascular smooth muscle cells.
Foam cell formation is a key event in the onset and progression of atherosclerotic lesions. We have previously reported that internalization of aggregated low density lipoproteins (agLDLs) by vascular smooth muscle cells (VSMCs) produces cholesteryl ester (CE) accumulation in these cells. The aim of this study was to analyze whether the low density lipoprotein receptor-related protein (LRP) med...
متن کاملMinimally Modified LDL Upregulates Endothelin Type A Receptors in Rat Coronary Arterial Smooth Muscle Cells
Minimally modified low-density lipoprotein (mmLDL) is a risk factor for cardiovascular disease. The present study investigated the effects of mmLDL on the expression of endothelin type A (ET(A)) receptors in coronary arteries. Rat coronary arteries were organ-cultured for 24 h. The contractile responses were recorded using a myographic system. ET(A) receptor mRNA and protein expressions were de...
متن کاملLDL stimulates mitogen-activated protein kinase phosphatase-1 expression, independent of LDL receptors, in vascular smooth muscle cells.
Low density lipoprotein (LDL) is a well-established risk factor for atherosclerosis, stimulating vascular smooth muscle cell (SMC) differentiation and proliferation, but the signal transduction pathways between LDL stimulation and cell proliferation are poorly understood. Because mitogen-activated protein kinases (MAPKs) play a crucial role in mediating cell growth, we studied the effect of LDL...
متن کاملEffect of LDL concentration polarization on the uptake of LDL by human endothelial cells and smooth muscle cells co-cultured.
To substantiate our hypothesis that concentration polarization of low-density lipoprotein (LDL) plays an important role in the localization of atherogenesis, we investigated the effects of wall shear stress and water filtration rate (or perfusion pressure) on the luminal surface LDL concentration (c(w)) and the LDL uptake by human vascular endothelial cells and smooth muscle cells co-cultured o...
