Figure 5From: Quercetin suppresses inflammation by reducing ERK1/2 phosphorylation and NF kappa B activation in Leptin-induced Human Umbilical Vein Endothelial Cells (HUVECs)Quercetin partially suppressed leptin-induced TNFα secretion. TNFα secretion was markedly increased in leptin-induced HUVECs as compared to control, and was partially decreased after quercetin addition. L0Q0 control HUVECs without leptin and quercetin; L0Q125 without leptin, but with 125 μM quercetin; L500Q0 with 500 ng/mL leptin, but without quercetin; L500Q125 with 500 ng/mL leptin and 125 μM quercetin. Means without a common letter differ, at least p < 0.05.Back to article page
