Study challenges our understanding of premature ageing

Pranjal Malewar

The study offers a new outlook on how mitochondrial dysfunction may contribute to aging by affecting cellular nucleotide pools.

Family tree revealing paternal inheritance of mitochondrial DNA (mtDNA). Luo et al.2 sequenced the mtDNA of several members of a family in which many individuals had a high level of mtDNA heteroplasmy (the presence of distinct genetic variants in the same cell). This mtDNA variability is denoted by two colours in the same silhouette of an individual. The analysis showed that some of the individuals with heteroplasmy had inherited mtDNA from both of their parents, breaking the usual pattern of exclusive maternal inheritance of mtDNA. Luo et al. suggest that the ability to inherit paternal mtDNA is a genetic trait.
