flies fed an “anti-Atkins” low protein diet live longer

Researchers at the Buck Institute are studying the regulation of mitochondrial genes in the fruitfly Drosophila melanogaster in relation to ageing and lifespan. They are trying to understand how mitochondrial function relates to diet and energy metabolism, specifically the molecular … Continue reading

somatic mtDNA mutations

A paper by Alexandra Kukat and Aleksandra Trifunovic demonstrates that somatic mtDNA mutations have the capacity to cause a variety of aging phenotypes in mammals. However, the relative importance of somatic mtDNA mutations in mammalian aging remains unclear, as the … Continue reading

mitochondrial DNA subunits

Rajindar Sohal and colleagues recently made a study comparing the expression of mitochondrial DNA encoded subunits of cytochrome c oxidase (CcO) in Drosophila melanogaster. They compared mitochondrial proteins from 15-, 25-, 35-, 47- and 60-day-old flies. Subunits I, II and … Continue reading
