Fig. 1From: Triptolide attenuates lipopolysaccharide-induced inflammatory responses in human endothelial cells: involvement of NF-κB pathwayThe effects of triptolide on the viability of human umbilical vein endothelial cells (HUVECs). HUVECs were treated with triptolide (25, 50 or 100 nM) for the indicated times. Cell viability was determined by an MTT assay. Data are expressed as the mean ± standard error of the mean. *p < 0.05 and **p < 0.01, compared with the corresponding control groupBack to article page
