The results indicated that Ki-67 was significantly upregulated in many cancers including sarcoma (SARC), stomach adenocarcinoma (STAD), lung adenocarcinoma (LUAD), lung squamous cell carcinoma (LUSC), colon adenocarcinoma (COAD) and liver hepatocellular carcinoma (LIHC) (Fig. 4a). This evidence concerns the gene MKI67 and gastric adenocarcinoma.
