Here, we show that reintroduction of this EPH receptor into colon cancer cells with low levels of either wild type (LS174T) or mutant (DLD1) EPHA3 and that express the preferred EPHA3 ligand (Ephrin A5), has no effects on the growth of cancer cells on a solid substrate, soft agar or when grown as subcutaneous xenografts in immunodeficient NOD/SCID mice. This evidence concerns the gene EPHA3 and colonic neoplasm.
