Dynamic MTORC1-TFEB feedback signaling regulates hepatic autophagy, steatosis and liver injury in long-term nutrient oversupply

Normal metabolism requires a controlled balance between anabolism and catabolism. It is not completely known how this balance can be retained when the level of nutrient supply changes in the long term. We found that in murine liver anabolism, as represented by the phosphorylation of RPS6KB (ribosomal protein S6 kinase), was soon elevated while catabolism, as represented by TFEB (transcription factor EB)-directed gene transcription and lysosomal...
