CBX7 and neoplasm: Supplementary Table 1 summarizes the studies on gastric cancer. CBX1/2/3/4/6 were significantly up-regulated in different gastric adenocarcinoma types, whereas CBX7 was significantly down-regulated in diffuse gastric adenocarcinoma. These findings are in line with observation in different cancer types, which indicates the conserved function of the CBXs family among various tumor types.
