Fig. 7From: Small ubiquitin-related modifier 2/3 interacts with p65 and stabilizes it in the cytoplasm in HBV-associated hepatocellular carcinomaProteasome inhibitor MG132 abolished SUMO2/3-mediated p65 stability. SMMC7721 cells were transfected with GFP-SUMO2 (a) and GFP-SUMO3 (b). At 24 h after transfection, the cells were treated with MG132 (20 μM) for 6 h. Then the lysate was subjected to Western blotting analysisBack to article page
