The present invention is directed to an antigen found on the surface of rat and human pancreatic cancer cells and provides antibodies of high specificity and selectivity to this antigen as well as hybridomas secreting the subject antibodies. Methods for both the diagnosis and treatment of pancreatic cancer are also provided. This tissue marker of pancreatic adenocarcinoma, an approximately 43.5 kD surface membrane protein designated PaCa-Ag1, is completely unexpressed in normal pancreas but abundantly expressed in pancreatic carcinoma cells. Moreover, a soluble form of PaCa-Ag1 exists, having a molecular weight about 36 to about 38 kD, that is readily identified in sera and other body fluids of pancreatic cancer patients, using a subject antibody.

The present invention provides a method for detecting pancreatic carcinoma in a subject. The method includes contacting a nucleic acid-containing specimen from the subject with an agent that provides a determination of the methylation state of at least one gene or associated regulatory region of the gene and identifying aberrant methylation of regions of the gene or regulatory region, wherein aberrant methylation is identified as being different when compared to the same regions of the gene or associated regulatory region in a subject not having the pancreatic carcinoma, thereby detecting pancreatic carcinoma in the subject.

AnnexinA2 (ANXA2), a member of the Annexin family of calcium-dependent, phospholipid binding proteins, is one of a panel of identified antigens recognized by the post-vaccination sera of patients who demonstrated prolonged disease-free survival following multiple vaccinations. AnnexinA2 is abundantly expressed in pancreatic adenocarcinomas and cell surface/membrane AnnexinA2 increases with the progression from premalignant lesions to invasive pancreatic adenocarcinomas. The cytoplasmic to cell surface translocation of AnnexinA2 expression is critical for pancreatic cancer cell invasion. In addition, phosphorylation of AnnexinA2 at Tyrosine 23 is important for its localization to the cell surface and for the invasion of pancreatic cancer cells. Finally, loss of AnnexinA2 leads to the loss of the Epithelial-Mesenchymal Transition.
