Abstract

Communication between endothelial and smooth muscle cells (SMCs) contributes to atherosclerosis induced by atherogenic factors, such as oxide LDL. Asymmetric dimethylarginine (ADMA), a newly found cardiovascular risk factor, accumulates in the culture medium of oxide LDL (oxLDL)-treated endothelial cells and positively correlates with atherosclerosis. This study demonstrates that ADMA mediates the communication between endothelial cells and SMCs induced by oxLDL leading to SMC migration. In addition, the present study suggests exogenous ADMA directly induces SMC migration via p38 and ERK1/2 MAPK signaling transduction way. Investigations to identify the factors regulating VSMC migration may provide novel insights into atherosclerosis and its complications. © 2011 Federation of European Biochemical Societies.
