Mitochondria are considered a key element in the process of organismic aging, because of their fundamental role in cellular energy generation. In the course of oxidative phosphorylation, harmful free radicals are continuously produced damaging the mitochondrial (mt) genome. One of the consequences is the occurrence of large-scale deletions in mtDNA molecules. The 4977bp common deletion accumulates...
It has been suggested that deletions of mitochondrial DNA (mtDNA) are important players with regard to the ageing process. Since the early 1990s, the 4977bp deletion has been studied in various tissues, especially in postmitotic tissues with high energy demand. Unfortunately, some of these studies included less than 10 subjects, so the aim of our study was to quantify reliably the deletion amount...
