Description:
Deep venous thrombosis (DVT) is a potentially life-threatening disorder with high morbidity. Uvaol is a natural pentacyclic triterpene possessing multiple pharmacological activities. Nevertheless, the role of uvaol in DVT is unclarified. Human umbilical vein endothelial cells (HUVECs) were treated with hydrogen peroxide (H2O2) to mimic DVT in vitro. CCK-8 assay and flow cytometry were utilized for measuring cell viability and apoptosis, respectively. Levels of the cell injury marker, thrombosis-associated factors, inflammatory cytokines, and oxidative stress-related markers were examined by commercial assay kits. Western blotting was used for evaluating the expression of mitogen-activated protein kinase (MAPK) signaling-associated proteins. Uvaol treatment attenuated H2O2-induced HUVEC apoptosis and injury. Uvaol reduced the expression of pro-thrombotic factors and inflammatory cytokines and attenuated oxidative stress in H2O2-stimulated HUVECs. Uvaol inhibited MAPK signaling pathway in H2O2-stimulated HUVECs. Activating MAPK signaling reversed uvaol-mediated protective effects on H2O2-treated HUVECs. Uvaol treatment alleviates H2O2-induced HUVEC injury, apoptosis, and oxidative stress by inactivating MAPK signaling.
