Aims
The purpose of this study is to investigate the effect of PP2A on the progression of AS and the special molecular mechanism. Main
Methods
The expression of PP2A in Human umbilical vein endothelial cells (HUVECs) induced by different concentrations of Ox-LDL was measured by RT-PCR and Western blot. The binding activity of PP2A and LOX-1 was determined by CoIP assay. Western blot was used to measure the protein expression of VCAM-1, ICAM-1 and MCP-1. Key finding: The
Significance
it suggests that PP2A alleviates Ox-LDL-induced dysfunction and inflammatory response of HUVECs potentially by regulating the LOX-1/ROS/MAPK axis，which suggests that PP2A has anti-inflammatory effect during the formation of as, and the molecular therapy of PP2A provides a theoretical basis.
