Bone morphogenetic proteins (BMPs) signaling has an emerging role in pancreatic cancer. However, because of the multiple effects of different BMPs, no final conclusions have been made as to the role of BMPs in pancreatic cancer. In our studies, we have focused on bone morphogenetic protein 2(BMP-2) because it induces an epithelial to mesenchymal transition (EMT) and accelerates invasion in the human pancreatic cancer cell line Panc-1. It has been reported that the phosphatidylinositol 3-kinase (PI3K)/Akt pathway mediates invasion of gastric and colon cancer cells, which is unrevealed in pancreatic cancer cells. The objective of our study was to investigate whether BMP-2 mediated invasion might pass through the PI3K/Akt pathway. Our results show that expression of phosphorylation of Akt was increased by treatment with BMP-2, but not Noggin, a BMP-2 antagonist. Then pretreatment of Panc-1 cells with LY294002, an inhibitor of the PI3K/AKT pathway, significantly inhibited BMP-2-induced EMT and invasiveness. The data suggest that BMP-2 accelerates invasion of panc-1 cells via the PI3K/AKT pathway in panc-1 cells, which gives clues to searching new therapy targets in advanced pancreatic cancer.
