Scientific Background: EphA2 is a protein-tyrosine kinase of the TK group and Eph family. It is a receptor that displays promiscuous binding to membrane-bound ligands of the ephrin-A family on adjacent cells. It is activated by binding ephrin-A1, A2, A3, A4 or A5. Phosphorylation of Y735 increases phosphotranserase activity and interaction with PIK3R1. EphA2 activation regulates integrin-dependent adhesion, cellular migration, proliferation, and differentiation. EphA2 also participates in bone remodeling by directly regulating both osteoclastogenesis and osteoblastogenesis. EphA2 may be an oncoprotein (OP). Significantly elevated EphA2 expression has been observed in many types of human cancer and appears to be involved in mediating communication between RAS-PI3K/Akt and RAS-MAPK intracellular signalling pathways, which are both known to promote tumourigenesis. Additionally, EphA2 is required for UV-radiation induced apoptosis. UV-radiation is a potent carcinogen responsible for the development of melanoma. However, further characterization of melanoma cell lines revealed either a pro-apoptotic or anti-apoptotic role for EphA2 dependent upon the cellular context. Additionally, studies performed in breast cancer cell lines revealed a link between EphA2 expression levels and changes in cytoskeletal morphology and the recruitment of disintegrin and metalloprotease-10 (MMP10) enzymes, thus suggesting a role for theEphA2 protein in the promotion of tumour invasion and metastasis.
