Mitochondrial DNA mutations in human neoplasia.

Abstract excerpt

Many models of tumour formation have been put forth so far. In general they involve mutations in at least three elements within the cell: oncogenes, tumour suppressors and regulators of telomere replication. Recently numerous mutations in mitochondria have been found in many tumours, whereas they were absent in normal tissues from the same individual. The presence of mutations, of course, does not prove that they...
