Protective effect of conjugated linoleic acid on vascular endothelial cells / 中国海洋药物

ABSTRACT

Objective To investigate the effects of conjugated linoleic acid(CLA)on survival rate of vascular endothelial cells(VEC).Methods The survival rate of VEC was assessed using MTT method after treating with CLA.Apoptosis and necrosis of the cells were determined using annexin V-propidium iodine double staining.Results CLA significantly increased the cell survival rate to 126.3% after treating for 72h at a dose of 2?mol?L-1,survival in a time-and dose-dependent manner when the concentration was less than 5?mol?L-1.CLA could partly prevent the death of VEC induced by PA and SA.Conclusion CLA can partly prevent the death of VEC induced by PA and SA.The results suggest that CLA are important for the survival of vascular endothelial cells.
