Authors: Tian Y, Merkwirth C, Dillin A
The mitochondrial unfolded protein response (UPR(mt)) promotes the recovery of dysfunctional mitochondria. Surprisingly, UPR(mt) activation inadvertently maintains and propagates the deleterious mtDNA in a heteroplasmic Caenorhabditis elegans strain, with detrimental consequences. This study extends our understanding of the UPR(mt) and provides a possible therapeutic target for diseases associated with mtDNA mutations.
