Scientists from the Longevity Research Institute (LRI), which was formed by the merger of SENS Research Foundation and Lifespan.io, have achieved expression of an essential mitochondrial gene in the nucleus and proper functioning of the protein. This could pave the way for curing diseases caused by mitochondrial mutations [1].
The fragile mitochondrial DNA
The prevailing scientific consensus is that mitochondria were once independent microorganisms that entered a symbiotic relationship with larger cells. This duo gave rise to eukaryotic cells: the building blocks of all multicellular life. Without that fateful “marriage,” complex life would not exist, as mitochondria provide cells with essential energy via oxidative phosphorylation.
