MDVs to the rescue: How autophagy-deficient cancer cells adapt to defective mitophagy

Abstract

Cancers are dependent on mitochondria, the powerhouse of the cell, and autophagy, the mechanism to preserve mitochondrial quality and function. In this issue of Developmental Cell, Towers et al. identify mitochondria-derived vesicles (MDVs) as a new adaptive mechanism enabling cancer cells to compensate for autophagy loss and to maintain mitochondrial function.
