Abstract:
:Starvation of animals or cells triggers autophagic degradation of cell contents to retrieve nutrients, but, paradoxically, mitochondria enlarge. This is now shown to result from inhibition of mitochondrial fission through PKA-mediated phosphorylation of the GTPase DRP1. Elongation of mitochondria optimizes ATP production and spares them from autophagy-mediated destruction.

评论,新闻abstract::In response to DNA damage, eukaryotic cells use a system of checkpoint controls to delay cell-cycle progression. Checkpoint delays provide time for repair of damaged DNA before its replication in S phase and before segregation of chromatids in M phase.
