Abstract Shear stress and oxidized low-density lipoprotein (oxLDL) caused by abnormal blood is critical to angiogenesis for atherosclerosis. However, the mechanism in shear stress or ox-LDL regulated angiogenesis is still not well understood. There is the hypothesis that shear stress or oxLDL regulates angiogenesis through the vascular endothelial growth factor (VEGF) signaling pathway. It is discovered that both high shear stress and low concentration of oxLDL contribute to angiogenesis, which is inhibited once the VEGF or VEGFR expression is knocked down. The expression of p-FAK and p-paxillin is regulated by the VEGF/VEGFR signal axis. VEGFR2, p-FAK, More >
