Research Abstract

The aim of this study was to identify the molecules to regulate EMT and the mechanism to control cellular senescence in pancreatic cancer. We revealed that miR 126 was down-regulated in invasive pancreatic cancer compared to non-invasive IPMN. In addition, the expression level of MSX2, inducer of EMT in pancreatic cancer, was found to be utilized for diagnosis of pancreatic cancer. Moreover, MSX2 expressing pancreatic cancer showed the chemoresistance, suggesting that EMT related molecules could be therapeutic target for pancreatic cancer.
