However, compared with 31 gastric mucosa samples, the mRNA expression level of PSMA7 was significantly upregulated in gastric intestinal type adenocarcinoma (cases = 26, fold change = 2.516, p < 0.001) and gastric mixed adenocarcinoma (cases = 4, fold change = 2.555, p < 0.001) in DErrico's dataset [32]. This evidence concerns the gene PSMA7 and gastric intestinal type adenocarcinoma.
