Additional file 2: of Inhibition of TPL2 by interferon-α suppresses bladder cancer through activation of PDE4D

Figure S2. IFN-α inhibits the phosphorylation of ERK in bladder cancer cells. (A) 5637 cells were treated with IFN-α (2 × 104 U/mL) for specific time points. (B) 5637 cells were treated with various concentrations of IFN-α for 24 h. In both cases, p-ERK and ERK levels were analyzed by performing western blotting. (PDF 107 kb)
