Discovery of a hidden epigenetic clock in mitochondria reveals a 'lifespan limit line'

Building on their work on epigenetics of aging and transposable elements, researchers Dr. Ádám Sturm and Dr. Tibor Vellai from Eötvös Loránd University have made another advance in understanding the molecular mechanisms of aging. Their latest study, published in the International Journal of Molecular Sciences, reveals a novel epigenetic mechanism in mitochondrial DNA (mtDNA) that could transform our approach to aging research and diagnostics.
