For a thorough characterization of these promising common features in distinct KRAS colorectal and pancreatic cell mutation context, we assessed the expression levels of these nine genes and a member of the chorionic gonadotropin protein, CGB8, and the enzyme peptidyl arginine deiminase 1 (PADI1), which are involved in Protein Citrullination, because of their high expression changes and recent implications in many cancers [32, 33, 34]. This evidence concerns the gene PADI1 and cancer.
