The STAT1 gene was highly expressed in most tumors, including cholangiocarcinoma (CHOL), colon adenocarcinoma (COAD), esophageal carcinoma (ESCA), liver hepatocellular carcinoma (LIHC), pancreatic adenocarcinoma (PAAD), READ, and stomach adenocarcinoma (STAD) (Figure 1A). This evidence concerns the gene STAT1 and gastric adenocarcinoma.
