EPHA1, EPHA2, EPHA3, EPHA4, EPHA5, EPHA6, EPHA7, EPHA8, EPHA10, EPHB1, EPHB2, EPHB3, EPHB4 and EPHB6 are EPH family receptors for Ephrin family ligands. Ephrin/EPH signaling pathway networks with the WNT signaling pathway during embryogenesis, tissue regeneration, and carcinogenesis. TCF/LEF-binding sites within the promoter region of human EPH family members were searched for by using bioinformatics and human intelligence. Because five TCF/LEF-binding sites were identified within the 5'-promoter region of the EPHA7 gene, comparative genomics analyses on EPHA7 orthologs were further performed. EPHA7-MANEA-FHL5 locus at human chromosome 6q16.1 and EPHA10-MANEAL-FHL3 locus at human chromosome 1p34.3 were paralogous regions within the human genome. Human EPHA7 mRNA was expressed in embryonic stem (ES) cells, neural tissues, duodenal cancer and parathyroid tumors, while mouse Epha7 mRNA was expressed in fertilized egg, Rathke's pouche, visual cortex, pituitary gland, other neural tissues, pancreas, lung tumors and mammary tumors. The chimpanzee EPHA7 gene and cow Epha7 gene were identified within NW_107969.1 and AC155055.2 genome sequences, respectively. Five TCF/LEF-binding sites within human EPHA7 promoter were conserved in the chimpanzee EPHA7 promoter, and three TCF/LEF-binding sites in the cow Epha7 promoter, but none in the mouse Epha7 promoter. Primates and cow EPHA7 orthologs were identified as evolutionarily conserved targets of the WNT/beta-catenin signaling pathway. D6S1056 microsatellite marker within EPHA7 gene is deleted in prostate cancer. Deletion and/or promoter CpG hypermethylation could explain the EPHA7 down-regulation in human tumors. EPHA7 is a target of systems medicine, especially in the fields of regenerative medicine and oncology.
