A total of four IRLs were identified and selected for risk modeling through univariate cox analysis (Figure 1A) and lasso analysis (Figures 1B, C); among them, TFAP2A-AS1 and AL133215.2 showed a significantly high expression, while LINC02078 and AP000911.1 had a significantly low expression in cancer tissues (Figure 1D). This evidence concerns the gene TFAP2A and cancer.
