CircPTPRA acts as a tumor suppressor in bladder cancer by sponging miR-636 and upregulating KLF9

Figure 2. Expression of circPTPRA in human BC specimens. (A) Relative expression of circPTPRA in BC samples and matched adjacent normal tissues (Wilcoxon matched-pairs signed rank test). (B) Relative expression of circPTPRA according to BC clinical T stage (Mann-Whitney U test). (C) Expression of circPTPRAaccording to BC clinical tumor size (Mann-Whitney U test). (D) Kaplan-Meier analysis of overall survival in BC patients. Data are presented as the mean and 95% CI. *P< 0.05, **P < 0.01
