Fig. 2From: Inhibition of connexin 43 attenuates oxidative stress and apoptosis in human umbilical vein endothelial cellsEffects of LPS stimulation with or without Gap19 treatment on apoptosis and ROS levels in HUVEC. After continuous exposure to 400 ng/mL LPS with or without 100 μM Gap19 for 24 h, apoptosis (a, b) and ROS levels (c, d) in HUVECs were assessed, respectively, by Annexin V-FITC/PI and DCFH-DA using flow cytometry. Gap19 was used as an inhibitor of Cx43. Experiments were performed in 3 biological replicates and data are presented as mean ± SD. **P < 0.01 compared with control. ##P < 0.01 compared with LPSBack to article page
