【摘要】Objective To investigate hydrogen peroxide (H2O2) and transforming growth factor-β2 (TGF-β2) induced fibronectin (FN), collagen 1 (COL1), nuclear factor (NF)-κB P65 proteins and interlukin (IL)-1βgene expression in human trabecular meshwork cells (HTMCs), and the interventional mechanism of resveratrol (RSV). Methods (1) HTMCs with 70 to 80%confluency were divided into 5 groups. The experimental groups were treated with serum-free medium and with H2O2 at concentrations of 150, 300, 450 and 800μmol/L. The control group was treated with 0μmol/L H2O2. The protein levels of FN, COL1, NF-κB P65 and NF-κB P65 phosphorylation (P-NF-κB P65) were measured by Western blot assay. The expression of IL-1βgene was measured by qPCR. (2) HTMCs were divided into 3 groups. The control group was treated withserum-free medium and without H2O2 and RSV. The H2O2 group was treated with 300μmol/L H2O2. The H2O2+RSV group was treated with 300μmol/L H2O2 and 25μmol/L resveratrol (RSV). The expressions of proteins and genes mentioned above were detected in three groups. NF-κB P65 nuclear translocation was assessed
