The hypothesis that changes in oxidative phosphorylation induce by mitochondrial dysfunction involved in tumorgenesis is so long discussed. Mitochondrion is vital for cell proliferation and has irreversible central role in the apoptosis (programmed cell death). Furthermore, mtDNA mutations have been founded in various cancer cells; although, the role of mitochondrial DNA mutations remains largely unknown. The mitochondria mutations do not lead to its deactivation but these mutations can change biosynthesis, bioenergetics, signal transduction, transcription and chromatin structure of the cell. In this paper, the major impairment in mtDNA and its effect on tumorgenesis were discussed.
