Figure 1. Correlation between DNMT3B and miR-34a in bladder cancer tissues. (A) The protein level of DNMT3B was assessed using tissue microarrays in 30 bladder cancer tissues. (B, C) Overall survival analysis of bladder cancer patients who were divided into two groups based on the expression level of DNMT3B (B) or miR-34a (C). Survival analysis was performed using the Kaplan-Meier method and the logrank test. DNMT3B, DNA methyltransferase 3B.
