Mitochondrial Genome (mtDNA) and Human Diseases
Journal Title: Science Insights - Year 2021, Vol 38, Issue 4
Abstract
Mitochondria not only provide necessary energy for cells, but more importantly, they participate in the regulation of various biological functions and activities of cells. As one of the critical components of the body’s genome, mitochondrial genome (mtDNA) is the key to cell bioenergetics and genetics. However, since no protection of histones and a complete self-repair system, mtDNA is extremely prone to mutate. Human diseases caused by mtDNA mutations are only transmitted through the maternal line. The same phenotype can come from multiple mtDNA mutations, and the same mtDNA mutation can lead to multiple phenotypes. This is the major reason that makes the diagnosis and identification of mtDNA genetic diseases difficult. Meanwhile, mtDNA mutations may be the culprit involved in mediating the aging and tumorigenesis. Currently, no effective therapeutics for diseases caused by mtDNA mutations, but with the deepening of research and technological advancement, it is promising that breakthroughs in the diagnosis and treatment of mitochondrial-related diseases in the near future.
