Animal Model of Pancreatic Cancer Offers Potential Treatment Target, Massachusetts General Hospital Study

Detailed analysis of genes expressed in circulating tumor cells (CTCs) -- cells that break off from solid tumors and travel through the bloodstream -- has identified a potential treatment target in metastatic pancreatic cancer. In a report that will appear in Nature and has received advance online publication, Massachusetts General Hospital (MGH) Cancer Center investigators describe finding increased expression of WNT2, a member of a known family of oncogenes, in CTCs from a mouse model of the deadly tumor and from human patients. The researchers were able to capture the CTCs - present in the bloodstream at extremely low levels - using a microchip-based device previously developed by members of the team.
