Diurnal metabolic rhythms add an important temporal dimension to metabolic homeostasis in mammals. While it remains a challenge to untangle the intricate networks of crosstalk among the body clock, nutrient signaling, and tissue metabolism, there is little doubt that the rhythmic nature of nutrient and energy metabolism is a central aspect of metabolic physiology. Disruption of the synchrony between clock and metabolism has been causally linked to diverse pathophysiological states. As such, restoring the rhythmicity of body physiology and therapeutic targeting directed at specific time windows during the day may have important implications in human health and medicine. In this review, we summarize recent findings on the integration of hepatic glucose metabolism and the body clock through a regulatory network centered on the PGC-1 transcriptional coactivators. In addition, we discuss the transcriptional mechanisms underlying circadian control of the autophagy gene program and autophagy in the liver.
