Fig. 2From: Isobavachalcone attenuates TNF-α-induced ICAM-1 and VCAM-1 expression in human umbilical vein endothelial cells by regulating the NF-κB signaling pathwayCell viability assay of HUVECs. The HUVECs were exposed to concentrations of isobavachalcone from 0.1 to 50 µM for 24 h and viability was detected using the CCK-8 assay. Control cells (CB) received vehicle alone. All data are expressed as the mean ± SD of the three independent experiments. *, p < 0.05 vs. CBBack to article page
