CBX4 and diffuse gastric adenocarcinoma: In addition, in the DErrico dataset, increased mRNA levels of CBX4 in diffuse gastric adenocarcinoma tissues (P value = 2.45e−05, fold change = 2.466)32 and gastric mixed adenocarcinoma tissues (P value = 2.29e−06, fold change = 3.314)32 were observed (Table 1).
