The results showed that PDSS1 is significantly overexpressed in liver hepatocellular carcinoma (LIHC), bladder urothelial carcinoma (BLCA), esophageal carcinoma (ESCA), breast infiltrating carcinoma (BRCA), glioblastoma multiforme (GBM), uterine corpus endometrial carcinoma (UCEC), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC), pancreatic cancer (PAAD), and gastric cancer (STAD) (p<0.05;Figure 1A). This evidence concerns the gene PDSS1 and gastric adenocarcinoma.
