It is suggested that oxLDL is decisive in the initiation and development of
atherosclerotic injuries. The up-regulation of oxidative stress and the
generation of ROS act as key modulators in developing pro-atherosclerotic and
anti-atherosclerotic processes in the human endothelial wall. In this present
study, we confirmed that metformin enhanced SIRT1 and AMPK expression in human
umbilical vein endothelial cells (HUVECs). Metformin also inhibited
oxLDL-increased LOX-1 expression and oxLDL-collapsed AKT/eNOS levels. However,
silencing SIRT1 and AMPK diminished the protective function of metformin against
oxidative injuries. These results provide a new insight regarding the possible
molecular mechanisms of metformin.
