Then, we also explored the correlation between the expression of 11 ROS-related genes and TNM stages in liver cancer, and the findings showed that the expression of CDKN2D, G6PD, MSRA, OXSR1, PFKP, and STK25 was connected with TNM stages (P < 0.05) (Figure 15(b)). This evidence concerns the gene STK25 and liver cancer.
