AMY2A and adenocarcinoma: Three adenocarcinomas that clustered away from the majority of adenocarcinomas (shcx173, shcx172b, and shcx150) were distinguished by significant expression of genes encoding digestive enzymes, such as pancreatic amylase (AMY2A) and elastase (ELA3A), suggesting the presence of normal acinar cells in addition to the neoplastic component.
