IL-6 Inhibition Reduces STAT3 Activation and Enhances the Antitumor Effect of Carboplatin

Figure 5

Western blot analysis of STAT3 and downstream molecules: LoVo cells were treated with 20 μg/mL CBP, 500 μg/mL IL-6 neutralizing antibody (Ab), or both combined or PBS control for 24 h. Total proteins were then isolated for the western blot detection of p-STAT3, total STAT3, cyclin D1, cleaved caspase-3, and GAPDH.
