Background: Starved rat livers contain metabolites, which activate ChREBP and 14-3-3 interactions. Results: βHB and AcAc in the extract stabilize the ChREBP•14-3-3 complex in cytosol and inhibit the ChREBP/importin interactions. Conclusion: Ketone bodies are directly involved in the regulation of the nuclear/cytosol shuttle for ChREBP. Significance: Under starvation, ketone bodies serve as a "low glucose" sensor to inhibit lipogenesis.
