Ends end it via mitochondria: A telomere-dependent tumor suppressive mechanism acts during replicative crisis
Nassour et al. report that telomere dysfunction communicates with mitochondria via the ZBP1-TERRA-MAVS axis. This pathway activates a detrimental innate immune response that may promote the elimination of cells prone to oncogenic transformation during replicative crisis, thus serving as a telomere-dependent tumor-suppressive mechanism.
