Abstract
overexpressed Plexin B1 compared to normal pancreas tissues. Endogenous Plexin B1 and Met protein were detected in eight pancreatic cancer cell lines, with a variety of expression levels. Sema 4D stimulation activated Met protein, and significantly induced cell migration. Discussion: Here we show that Sema 4D involves in the regulation of cell motility through its receptor Plexin B1. And the results of immunostaining suggest that Sema 4D could play a role in the interaction between tumor cells and tumor microenvironment in pancreatic cancer tissues. As many attempts are now ongoing to target the tumor stroma, these findings provide a new insight into molecular targeted therapies for pancreatic cancer.
