Oxidative stress in the vascular wall has intimately been implicated in the apoptosis of human umbilical vein endothelial cells (HUVECs) by lysophosphatidylcholine (LPC). However, the major type of reactive oxygen species (ROS) in this apoptotic signaling pathway remains to be clarified. In this study, we report that superoxide mediate LPC-induced caspase-3 dependent apoptosis in cultured HUVECs....
The present study was designed to investigate the hypothesis that trans fatty acids can induce apoptosis of human umbilical vein endothelial cells (HUVEC). To test this hypothesis apoptosis was measured in HUVEC treated with 0.1, 1.0 or 5.0 mM trans elaidic acid (t-18:1) or linoelaidic acid (t,t-18:2) for 24 hours. For the detection of apoptosis, TdT-mediated dUTP nick end labelling assay (TUNEL),...
