Restricted mitochondrial protein acetylation initiates mitochondrial autophagy.
Because nutrient-sensing nuclear and cytosolic acetylation mediates cellular autophagy, we investigated whether mitochondrial acetylation modulates mitochondrial autophagy (mitophagy). Knockdown of GCN5L1, a component of the mitochondrial acetyltransferase machinery, diminished mitochondrial protein acetylation and augmented mitochondrial enrichment of autophagy mediators. This program was disr...
متن کاملGlioblastoma Cells Elongation Factor-2 Kinase Regulates Autophagy in Human
Elongation factor-2 kinase (eEF-2 kinase), also known as Ca/ calmodulin–dependent kinase III, regulates protein synthesis by controlling the rate of peptide chain elongation. The activity of eEF-2 kinase is increased in glioblastoma and other malignancies, yet its role in neoplasia is uncertain. Recent evidence suggests that autophagy plays an important role in oncogenesis and that this can be ...

متن کاملMitochondrial caspase keeps autophagy in flux
M any cellular stresses, including starvation, induce cells to up-regulate the process of auto-phagy, in which cytoplasmic content is engulfed into autophagosomes and delivered to lysosomes for degradation. Auto-phagy can promote cell homeostasis and survival by removing damaged proteins and organelles and recycling their breakdown products to enhance cell metabolism. On the other hand, autopha...
