氧化应激与血管细胞粘附分子-1的表达
英文摘要
Oxidative stress and expression of the vascular cell adhesion molecule-1 (VCAM-1) on vascular endothelial cells are early features in the pathogenesis of atherosclerosis and other inflammatory diseases. We have recently demonstrated a linkage between oxidation-reduction (redox) sensitive regulatory mechanisms and the expression of vascular endothelial cell genes, such as VCAM-1, that are involved in the early inflammatory processes characteristic of atherosclerosis. To explore the molecular determinants of atherogenesis, this proposal will characterize the molecular regulatory mechanisms through which modified low density lipoprotein (LDL) regulates VCAM-1 gene expression in human vascular endothelial cells and to identify the specific oxidation-reduction sensitive transcriptional regulatory factor(s) that mediate this effect. Using an integrated immunological, biochemical, cellular, and molecular biological approach in cultured human vascular endothelial cells, the regulatory effects of modified LDLs, both oxidized and glycated, as primary regulators and as modulators of cytokine activation of VCAM-1, ICAM-1, and E-selectin will be defined. This combined approach will be used to define the specific oxidant compounds within modified LDL that regulate VCAM-1 expression. Using these defined oxidants, an in vitro "knockout" approach is proposed, using synthetic oligonucleotides, to define the role of specific, endogenously expressed transcriptional regulatory factor(s) in the regulation of endogenous VCAM-1 gene expression.
