Mitochondrial gene expression changes in normal and mitochondrial mutant cells after exposure to ionizing radiation.

Abstract excerpt

Mitochondrial DNA (mtDNA) contains 13 genes that encode proteins of the oxidative phosphorylation complex that are involved in ATP generation. Leber's optic atrophy and Leigh's syndrome are diseases that are caused by point mutations in the mitochondrial genome and that have phenotypes associated with energy deprivation. We hypothesized that energy deficiency from mitochondrial mutations in these cells leads to...
