Progastrin overexpression imparts tumorigenic/metastatic potential to embryonic epithelial cells: phenotypic differences between transformed and nontransformed stem cells.

Abstract excerpt

We recently reported that overexpression of progastrin (PG) in embryonic epithelial cells (HEKmGAS cells) increased proliferation of the cells compared to that of control HEKC cells. Here, we report the novel finding that tumorigenic and metastatic potential of HEKmGAS cells is also increased significantly compared to that of HEKC cells. Cell surface-associated annexinA2 (CS-ANXA2) binds PG and is overexpressed...
