Figure 5. Effect of EM combined with DDP on GPX4 and FTH1 protein levels. (A, B) GPX4 and FTH1 protein expression in tumor tissues of nude mice in each group. (C, D) Graphs of GPX4 and FTH1 protein expression. All experiments were reread three times, nsp > 0.05, *P < 0.05, **P < 0.01, ***P < 0.001, ****P < 0.0001.
