TFEB controls cellular lipid metabolism through a starvation-induced autoregulatory loop
What this study shows
The authors found that fasting switches on the TFEB gene in mouse liver, muscle and kidney, and that TFEB drives its own transcription by binding CLEAR sites in its promoter, an autoregulatory loop that starvation strengthens. Liver TFEB overexpression changed 773 genes up and 611 down, with lipid catabolism as the top category, and acted largely through PGC-1alpha and PPARalpha: 74% of TFEB-induced genes failed to rise in mice lacking PPARalpha. Mice lacking liver TFEB built up liver fat and mobilised fat poorly during fasting and gained more weight on a high-fat diet, while liver TFEB overexpression prevented and halted diet-induced obesity and improved glucose tolerance in obese ob/ob mice; the lipid effect required autophagy (lost in Atg7-deleted liver). In C. elegans, the TFEB homologue HLH-30 was needed for lipid mobilisation and survival during starvation. Boundary: Mice and worms, with TFEB delivered by virus at overexpression levels. mTORC1 was not manipulated or measured; its role is inferred from earlier work. Not tested in people.
At a glance
| Evidence type | A Animal model Marked A because it is an animal intervention or observation study measuring an organismal outcome (model: Mice: 24 h fasting, liver-specific Tfeb knockout, liver-directed TFEB overexpression (helper-dependent adenovirus), high-fat diet and ob/ob obesity, liver Pgc1a and Atg7 deletion, Ppara knockout; HeLa cells, MEFs and primary hepatocytes; C. elegans hlh-30 mutants); the code names the system studied -- animal work can be rigorous and still not be human data. |
| Study type | 4 - Animal Study |
| Model system | Mice: 24 h fasting, liver-specific Tfeb knockout, liver-directed TFEB overexpression (helper-dependent adenovirus), high-fat diet and ob/ob obesity, liver Pgc1a and Atg7 deletion, Ppara knockout; HeLa cells, MEFs and primary hepatocytes; C. elegans hlh-30 mutants |

Extracted findings
These fields were extracted from the paper with AI assistance and have not been checked against the source. Read them as a pointer into the paper, not as curated claims; where they disagree with the curated summary above, the curated summary stands.
| Intervention | Fasting; liver-specific Tfeb deletion; liver-directed TFEB overexpression (HDAd-TFEB); high-fat diet; ob/ob mice; hlh-30 mutant worms |
| Target | TFEB -> PGC-1alpha / PPARalpha lipid catabolism programme |
| Model | Mouse; C. elegans |
| Effect | TFEB raised lipid catabolism gene expression and fat breakdown; liver TFEB overexpression prevented diet-induced obesity, TFEB loss worsened it |
