Survival analysis found that 83 DEGs were significantly associated with GC OS, among which the top three DEGs of significance were chorionic gonadotropin subunit beta 5 (CGB5), chorionic gonadotropin subunit beta 8 (CGB8), and secretin receptor (SCTR) (Figure 9a–d, Table S10). This evidence concerns the gene CGB8 and gastric cancer.
