a The whole-protein extracted from EC1/shCon. and EC1/shRAP80 #1 cells treated with 0.2 mg/ml CHX for indicated time points were subjected to western blot analysis to test the indicated proteins. The gray values were statistically analyzed. b The screening tests of E3 ligases and deubiquitylated enzymes in shCon. and shRAP80 #1 infected EC109 and EC1 cells using western blotting assays. c The whole-protein extracted from EC1/shCon. and EC1/shRAP80 #1 cells treated with 0.2 mg/ml CHX for indicated time points were subjected to western blot analysis to evaluate the stability of USP13. d, e The stable RAP80 knockdown EC109 and EC1 cells transfected with HA or HA-USP13 were subjected to colony formation analysis (d), the transfection efficiency was confirmed using western blotting assays (e)
