Alleviation of Hyperglycemia Induced Vascular Endothelial Injury by Exenatide Might Be Related to the Reduction of Nitrooxidative Stress
Exendin-4 attenuated high glucose induced endothelial injury in vitro. (a) Highglucose induced a decreased cell viability of HUVECs. (b) Effect of different dose of exendin-4 on cell viability of HUVECs. (c) Exendin-4 pretreatment improved cell viability challenged with highglucose. (d) Exendin-4 pretreatment alleviated the increased TUNEL positive cells induced by highglucose. (e) Exendin-4 pretreatment alleviated the increased caspase-3 activity induced by high glucose. = 5~10. *, ** versus vehicle; #, ## versus G.
