In TCGA-LUAD cohort, we compared the expression of GNPNAT1 in tumor and adjacent tissues, and the unpaired (p value = 3.28e−29, Figure 2(a)) and paired (p value = 4.425e−19, Figure 2(b)) tests both indicated that the expression of GNPNAT1 in the tumor was elevated. This evidence concerns the gene GNPNAT1 and neoplasm.
