prostaglandin-d2 and Carcinoma--Pancreatic-Ductal

Development of pancreatic ductal adenocarcinoma (PDA) involves acinar to ductal metaplasia and genesis of tuft cells. It has been a challenge to study these rare cells because of the lack of animal models. We investigated the role of tuft cells in pancreatic tumorigenesis.. We performed studies with LSL-Kras. Pancreata from KC mice had increased formation of tuft cells and higher levels of prostaglandin D. In mice with KRAS-induced pancreatic tumorigenesis, loss of tuft cells accelerates tumorigenesis and increases the severity of caerulein-induced pancreatic injury, via decreased production of prostaglandin D
