Research Abstract

In diabetes model, simvastatin exposure to cultured endothelial cells increased the nitric oxide(NO) production. PI_3K inhibitor inhibited the increase in eNOS expression in response to simvastatin, but phosphorylation of Akt protein was not affected by simvastatin. It is suggested that direct effect of PI3K without through Akt protein pathway may be involved in the statin induced activation of eNOS-NO signaling pathways.
