When selecting the LUAD_CPTAC_mRNA dataset, the mRNA levels of GAPDH in tumor tissues are significantly higher than in normal tissues (p < 0.001, Figure 2A), and the prognosis of the low expression group is significantly better than that of the high expression group when using the optimal cutoff point of GAPDH expression (p < 0.001, Figure 2B). This evidence concerns the gene GAPDH and neoplasm.
