The expression levels of RRAGB, RSPH9, RPS6KL1, and RXFP1 were significantly lower and RTL1 and RRM2 mRNA levels were significantly higher in the high-risk group than those in the low-risk group in NSCLC of TCGA-LUAD (Figure 8(b)). This evidence concerns the gene RRM2 and non-small cell lung carcinoma.
