Resveratrol Ameliorates Deep Vein Thrombosis-Induced Inflammatory Response Through Inhibiting HIF-1α/NLRP3 Pathway.

Deep vein thrombosis (DVT) has become a prevalent and increasingly serious problem globally and resveratrol (Res) is a natural antitoxin that inhibits arterial thrombosis. To investigate the effect of Res on DVT and further explore its mechanism, thrombosis was monitored at different time points and the pathological changes occurring in the inferior vena cava (IVC) and lung tissue were observed in Sprague-Dawley rats. The protein expression of HIF-1α and NLRP3 in the IVC and lung tissue and the concentrations of D-dimer (D2D), prothrombin fragment 1 + 2 (F1 + 2), interleukin-1β (IL-1β), caspase-1, and tissue factor (TF) in the plasma were determined. After setting different doses of Res groups and using low-molecular-weight heparin (LMWH) as a positive control to determine the effective experimental dose of Res, rats were further divided into sham, DVT, HIF-1α inhibitor, Res, and HIF-1α inhibitor + Res groups. The above indicators were tested repeatedly. The DVT was formed on the 1st day of modeling. With the extension of time, DVT was gradually institutionalized and finally recanalized. Lesions in the IVC and lung tissue were effectively ameliorated, and thrombosis was significantly decreased in the LMWH or 60 mg/kg Res-treated groups. The levels of D2D, F1 + 2, IL-1β, caspase-1, TF, and the expression of HIF-1α and NLRP3 were significantly reduced in the HIF-1α inhibitor, Res, and HIF-1α inhibitor + Res groups. Res can ameliorate DVT in rats by inhibiting HIF-1α/NLRP3 pathway, which provides a novel therapeutic strategy for DVT treatment.
