摘      要：OBJECTIVE: To define the effects of Xanthoceras sorbifolia(EXS) on vascular inflammation and the mechanisms in endothelial ***: Vascular protective effects of an ethanol extract of seeds from EXS(1-50 μg/mL) against tumor necrosis factor-α(TNF-α)-induced vascularinflammation were examined in human umbilical vein endothelial cells(HUVECs).RESULTS: EXS significantly decreased TNF-α-induced expression of cell adhesion molecules, such as intracellular adhesion molecule-1, vascular cell adhesion molecule-1, and endothelial cell selectin,in a dose-dependent manner. Pre-treatment with EXS significantly inhibited translocation and transcriptional activity of nuclear factor-κB(NF-κB) increased by TNF-α. EXS also significantly inhibited formation of intracellular reactive oxygen species(ROS). Moreover, the vascular protective effects of EXS were linked to up-regulation of heme oxygenase-1(HO-1) and nuclear factor E2-related factor-2(Nrf-2) expression. EXS-induced HO-1 expression was significantly decreased in SnPP(HO-1 inhibitor)-and HO-1 siRNA-treated cells, whereas an increase was found in cobalt protoporphyrin IX(CoPP)(HO-1 inducer)-treated cells. In addition, pretreatment with EXS increased HO-1 and Nrf-2 expression under TNF-α stimulation with or without N-acetyl-L-cysteine. Furthermore, the inhibitory effects of EXS on TNF-α-induced vascular inflammation were partially reversed in SnPP-and of HO-1siRNA-treated cells but increased by ***: These results suggest that EXS may have important implications for prevention of vascular complications associated with vascular inflammation by inhibition of the NF-κB/ROS pathway and activation of the Nrf-2/HO-1 pathway.
