Analysis of Common Deletion (CD) and a novel deletion of mitochondrial DNA induced by ionizing radiation

Abstract excerpt

PURPOSE: In order to identify supportive evidence of radiation exposure to cells, we analyzed the relationship between exposure to ionizing radiation and the induction of deletions in mitochondrial DNA (mtDNA). MATERIALS AND METHODS: Using human hepatoblastoma cell line, HepG2 and its derivatives, HepG2-A, -89 and -400, established after long term exposure to X-ray, mtDNA deletions were analyzed by polymerase...
