Outline of Final Research Achievements

Pancreatic stellate cells reorganize matrix components and lead pancreatic cancer invasion via the function of Endo180. Cancer-associated peritoneal mesothelial cells lead the formation of pancreatic cancer peritoneal dissemination by cancer interstitial interaction and microenvironment alteration. Furthermore, we identified autophagy was involved in the activation of pancreatic stellate cells. In the mouse model, suppression of autophagy of pancreatic stellate cells reduced tumor development and metastasis. From these results, we clarified the possibility of a new treatment targeting stroma.
