Mitochondrial quality control mediated by PINK1 and PRKN: links to iron metabolism and tumor immunity.

abstract：:Macroautophagy ("autophagy") is regulated by the same insulin-amino acid-mTOR signaling pathway that controls protein synthesis. Although the literature does not so far include any direct studies confirming this, we expect autophagy to increase during insulin resistance. We discuss the possibility that this may be a u...
