Abstract This study was designed to investigate the effects of mechanical (MS) and/or oxidized low-density lipoprotein on proliferation and apoptosis of RAW264.7 macrophages and the underlying mechanisms. The cultured quiescent RAW264.7 macrophages were subject to stimulation with MS and/or in the presence or absence of simvastatin and then harvested for Western blot, and immunoflourecence. Either MS or alone could cause increase in cell proliferation and apoptosis, while their combination led to an additive effect. In terms of mechanisms, MS and/or significantly increased phosphorylation levels of MAPKs (ERKs, JNKs and p38MAPK), promoted the reactive oxygen species (ROS) and up-regulated DNA methylation in… More >
