CEA binding agents and compositions to reverse CEA-mediated tumorigenic effects on human cancer cells, restore sensitivity to drug induced apoptosis and uses thereof
The present invention relates to differentiation, apoptosis and tumorigenicity. The present invention more particularly relates to compositions comprising ligands which target CEA such that the adhesion, differentiation-Inhibitory and apoptosis-resistance activities (tumorigenic effects) of Ig superfamily member, CEA, can be reduced or blocked. More particularly, the present invention relates to CEA-binding agents comprising compositions which reverse the CEA-mediated tumorigenic effects and enable a lowering of the doses of a chemotherapeutic agent. In one embodiment the invention relates to methods of reducing, preventing or reversing CEA-mediated tumorigenic effects comprising a use of an amount of a CEA declustering agent comprising compositions that can reverse a CEA mediated tumorigenic effect. In one embodiment, the invention further relates to compositions comprising a CEA declustering agent for reversing CEA-mediated tumorigenic effects and restoring drug induced apoptosis to human cancer cells and uses thereof.
