For women, it’s a little later, like early 30s. But after it reaches the peak, it tends to decrease,” Buckingham says. Some research indicates that the average person can expect around a 10 ...
For mitochondrial mutations the plan is not to repair them but to prevent harm from the mutations by putting suitably modified copies of the mitochondrial genes into the cell nucleus by gene therapy. The mitochondrial DNA experiences a high degree of mutagenic damage because most free radicals are generated in the mitochondria.
Mitochondrial disease is a group of disorders caused by mitochondrial dysfunction. Mitochondria are the organelles that generate energy for the cell and are found in every cell of the human body except red blood cells. They convert the energy of food molecules into the ATP that powers most cell functions.
Mitochondrial DNA has been known to encode 13 proteins. Recently, other short protein coding sequences have been identified, and their products are referred to as mitochondria-derived peptides. [15] The mitochondrial-derived peptide, humanin has been shown to protect against Alzheimer's disease, which is considered an age-associated disease. [16]

The theory implicates the mitochondria as the chief target of radical damage, since there is a known chemical mechanism by which mitochondria can produce ROS, mitochondrial components such as mtDNA are not as well protected as nuclear DNA, and by studies comparing damage to nuclear and mtDNA that demonstrate higher levels of radical damage on ...
