The mTORC1 pathway regulates multiple cellular processes to promote a switch from catabolic toanabolic metabolism and is thus under tight regulatory control by growth factor signaling and nutrientsensing pathways. Dysregulation of this complex machinery is implicated in many cancers, so definingthe key mechanisms by which mTORC1 senses changes in cellular homeostasis to activate growthsignals is of great relevance. Spatial regulation of mTORC1 signaling has been recognized as a majormechanism that influences the cellular response to nutrients and the lysosome is central to thisprocess.
