However, whether HPP1 has tumor suppressor activity is not clearly known. We have sought to investigate the effects of HPP1 on tumor growth and survival and to identify signaling pathways that mediate HPP1's mechanism of action. Forced expression of HPP1 into HCT116 colon cancer cell lines blocked the ability of HCT116 tumors to grown in vivo in nude mice. In cell culture, ectopic expression of HPP1 induces apoptosis and potently inhibits soft agar colony formation. HPP1 overexpression was also associated with a moderate reduction in in vitro proliferation characterized by an accumulation of cells in the G0/G1 phase of the cell cycle. Microarray analysis revealed that ectopic expression of HPP1 resulted in a dramatic upregulation of STAT1 as well as a large number of associated interferon-inducible genes. RNA interference-mediated abrogation of STAT1 reversed HPP1's antiproliferative effects. We conclude that HPP1 demonstrates tumor suppressive and pro-apoptotic activity, both in vitro and in vivo. Coupled with its inactivation in a number of tumor types, our data provides evidence to support the role of HPP1 as a tumor suppressor gene. Moreover, activation of the STAT1 pathway likely represents the principal mediator of HPP1's tumor suppressive properties."xsd:string |
