Mitochondrial DNA and Aging

Mikhail F. Alexeyev, Susan P. LeDoux, and Glenn L. Wilson

The goal of this chapter is to introduce the reader to the current state of the mitochondrial theory of aging as it pertains to mitochondrial DNA (mtDNA). Several aspects will be covered, including a basic biology of mitochondrial DNA, the experimental evidence supporting the mitochondrial theory of aging, and the experimental data that appear to contradict this theory. Finally, an overview of experimental approaches used to study mtDNA in aging will be presented, and weaknesses of each approach will be discussed.
