In addition, we also observed the significant correlations between CELF2 and ICM expression in urinary system tumours such as BLCA, KIRC and kidney renal papillary cell carcinoma (KIRP), as well as digestive system tumours such as esophageal carcinoma (ESCA), liver hepatocellular carcinoma (LIHC), pancreatic adenocarcinoma (PAAD) and STAD. This evidence concerns the gene CELF2 and pancreatic adenocarcinoma.
