Abstract

Aspects of the present invention provide novel Mig-7 encoding nucleic acids and Mig-7 polypeptides, RNAi (such as siRNA), recombinant DNA expression systems and host cells containing same, as well as methods of inhibiting expression of the subject nucleic acid molecules, inhibiting production of the encoded proteins or polypeptides, inhibiting metastasis of a carcinoma cell in a subject (including in humans), inhibiting migration/invasion of and mimicking of normal cells by carcinoma cells in a subject, detecting the presence of a cancer cell (e.g., a migrating/invading cancer cell or carcinoma cell mimic, tumor neovas-cularization, and/or vascular mimicry) in a sample of a subject's tissue or body fluids, and inhibiting the migration/invasion of an endothelial cell mimicking by a placental cell into the blood stream or vessels of a female mammal. Particular aspects relate to novel anti-Mig-7 antibodies, diagnostic and/or prognostic methods, and therapeutic methods comprising use of the inventive nucleic acids, polypeptides and antibodies or derivatives thereof.
