Abstract: Abstract: The study of mitochondria and diseases is a very hot field in biomedicine. We introduce here the basic knowledge of mitochondrial medicine and the hereditary character of mitochondrial diseases. In this review we highlight the most recent advances in the field, including the correlation of mitochondrial DNA (mtDNA) mutations and diseases, nuclear gene mutations and diseases. In particular, the molecular mechanisms of regulation of nuclear modifier genes on the phenotypic expression of mtDNA mutations are discussed in detail.
Key words: mitochondria; mitochondrial diseases; nuclear modifier genes; mitochondrial DNA (mtDNA)
