Oxidized low-density lipoproteins (oxLDL) have been show n to play a vitalrole in atherosclerosis, but the underlyingm olecularm echanism s have notbeen fully understood. The present study show ed that oxLDLs evoked phosphorylation and activation of p38 mtogen-activated protein kinase (MAPK) in rat vascular sm ooth m uscle cells (VSMCs) in concen-tration-and tim e-dependent m anners, reaching the m axim a activation in at 100 μg / M lwithin 5 m inutes.
