Association between SOD2 V16A variant and urological cancer risk
Figure 7. Association of SOD2 expression in bladder cancer subjects (A), based on patients’ race (C), the investigation of OS time (B) and DFS time (D). Expression of SOD2 was also down-regulated in bladder cancer tissues (Figure 7A), especially in Asian populations (Figure 7C, P < 0.05). No obvious difference was indicated in the effect of low SOD expression group and high expression group on OS time (Figure 7B, P = 0.570) and DFS time (Figure 7D, P = 0.200).
