| Study Title | Defining the mammalian coactivation of hepatic 12-hour clock and lipid metabolism |
| Study Summary | The 12-hour clock coordinates lipid homeostasis, energy metabolism and stress rhythms via the transcriptional regulator XBP1. However, the biochemical and physiological basis for integrated control of the 12-hour clock and diverse metabolic pathways remains unclear. Here, we show that steroid receptor coactivator SRC-3 coactivates XBP1 transcription and regulates hepatic 12-hour cistrome and gene rhythmicity. Mice lacking SRC-3 show abnormal 12-hour rhythms in hepatic transcription, metabolic functions, systemic energetics, and rate-limiting lipid metabolic processes including triglyceride, phospholipid and cardiolipin pathways. Notably, 12-hour clock coactivation is not only preserved, with its cistromic activation priming ahead of the zeitgeber cue of light, but concomitant with rhythmic remodeling in the absence of food. These findings reveal that SRC-3 integrates the mammalian 12-hour clock, energy metabolism, and membrane and lipid homeostasis, and demonstrates a role for the 12-hour clock machinery as an active transcriptional mechanism in anticipating physiological and metabolic energy needs and stresses. |
