Abstract

Anti-atherogenic effects in tumor necrosis factor-α (TNF-α)-stimulated human umbilical vein endothelial cells (HUVEC) are involved in the suppression of oxidative stress, cell adhesion molecules, and pro-inflammatory factors. This study investigated the vascular inflammation inhibitory activity of traditional Doenjang plays a key role in the pathogenesis and progression of atherosclerosis. The protective effects of Korean Deonjang was investigated on the expression of cell adhesion molecules (CAMs) in tumor necrosis factor (TNF)-α-induced human umbilical vascular endothelial cells (HUVECs). Deonjang extracts (20, 50, 100 μg/mL) decreased the expression of 20 ng/mL TNF-α-induced vascular cell adhesion molecule (VCAM)-1 intracellular adhesion molecule (ICAM)-1 proteins, and their corresponding mRNA levels. Nitric oxides (NO) produced by endothlial nitric oxides synthase (eNOS) dilated blood vessels, which had protective effects against platelet and leukocyte adhesion. While TNF-α-induced suppressed the production of nitric oxide in HUVECs, Doenjang restored NO production in HUVECs. In addition, Deonjang reduced the TNF-α-induced expression of inducible NO synthase (iNOS) and cyclooxygenase (COX)-2 mRNA levels. These results suggested that Doenjang can inhibited the production of cell adhesion molecules and inflammatory mediators, which could be a potential candidate for preventing atherosclerosis.
