Myoferlin: an indispensable component in VEGFA secretion by pancreas cancer cells.

In this poster, our laboratory showed the importance of myoferlin, a biomarker of pancreas cancer, in the controle of VEGF-A mediated angiogenesis. Our laboratory showed that silencing myoferlin in pancreas cancer cells, BxPC-3, provoques a decrease in cell prolifération in vitro and a decrease in tumor volumes in animal model. Myoferlin silencing also provokes a decrease in VEGF-A secretion in the conditioned medium and that decrease was abserved in the animal model as a decrease in microvessels dencity. It appeared that this decrease in secretion is due to a a blockage in the exocytosis. Our data also showed a significate correlation between myoferlin expression and microvessels density in patients section
