Protective Effect of Blueberry Anthocyanins on Oxidative Stress Injury by H2O2 of Human Umbilical Vein Endothelial Cells / 医学研究杂志

ABSTRACT

Objective To study the protective effect of blueberry anthocyanins on H2O2 induced human umbilical vein endothelial cells,HUVECs.Methods The cultured cells were divided into 3 groups:normal control group,H2O2 model group,blueberry anthocyanins group.MTT method was used to observe cell viability.Annexin V-FITC/PI straining was used to observe cell apoptosis.Flow cytometry was used to detect cell cycle.Results H2O2could induce HUVECs oxidative stress injury.Cell survival rate was positive correlated with drug concentration and action time.In the certain concentration range blueberry anthocyanin had a protective effect.Conclusion Blueberry anthocyanin can protect H2O2induced oxidative stress injury in HUVECs.
