Many protein markers for various cancers such as NMP22 (bladder cancer), CEA (colorectal cancer), CA15-3 and Her2/Neu (breast cancer), alpha-fetoprotein (liver cancer), CA-19-9 (pancreatic cancer), and CA-125 (ovarian cancer) have been identified using proteomics [3]. This evidence concerns the gene ERBB2 and ovarian carcinoma.
