CBX7 and esophageal adenocarcinoma: The overexpression of CBX3 (HR = 3.12, p = 0.00028) and CBX8 (HR = 2.27, p = 0.035) mRNAs in esophageal adenocarcinoma patients were significantly correlated with shorter OS, whereas the overexpression of CBX7 mRNA (HR = 0.48, p = 0.039) was significantly correlated with longer OS (Figure 4B).
