Eyes Absent 4 (EYA4) belongs to a family of protein phosphatases initially identified in Drosophila melanogaster as a compound of a network of transcriptional regulators associated with eye development. In the recent years, it has been demonstrated that EYA4 is deregulated in different types of cancer, acting as an oncogene in MPNST and as a tumor suppressor gene in esophageal adenocarcinoma, colon and colorectal cancer, hepatocellular carcinoma, lung cancer, acute myeloid leukemia and pancreatic cancer. Despite its association with different pathologies, the exact function of EYA4 is still unknown. A better understanding of the novel role of EYA4 in the maintenance of genome integrity and its implication in tumorigenesis and cancer development would help determining if EYA4 could be a new potential cancer therapeutic target. As part of this effort, colony formation assays have been performed after the exposure to different cytotoxic/genotoxic drugs, in order to study cell survival in EYA4 knocked down cells, and gain knowledge in sensitivity/resistant to chemotherapeutic agents. It was proven that EYA4 knockdowns and control has no resistance to MMC and MMS.
