Figure 4From: Piper sarmentosum inhibits ICAM-1 and Nox4 gene expression in oxidative stress-induced human umbilical vein endothelial cells Nox4 mRNA expression in HUVECs. Figure 4 represents the bar chart showing Nox4 mRNA expression in control, AEPS, H2O2 and AEPS + H2O2 groups. HUVECs treated with AEPS had lower Nox4 mRNA expression while H2O2 caused a higher Nox4 mRNA expression. Data are denoted as mean ± SEM of n = 6. (*) p < 0.05 vs. control; (#) p < 0.05 vs. H2O2.Back to article page
