miR-149 Alleviates Ox-LDL-Induced Endothelial Cell Injury by Promoting Autophagy through Akt/mTOR Pathway

<div>Enhanced autophagy and suppressed Akt/mTOR mediate the protective effects of miR-149 mimics. The inhibitor of autophagy (3-methyladenine, 3-MA, 100 <i>μ</i>m) and activator of Akt/mTOR pathway (insulin, 200 nm) were used. (a) Cell viability of HUVECs. (b) Caspase-3 activity of HUVECs. <svg height="10.7395pt" id="M11" style="vertical-align:-0.6370001pt" version="1.1" viewbox="-0.0498162 -10.1025 70.5189 10.7395" width="70.5189pt"
