Abstract

The circadian clock controls 24-h rhythmic processes. However, how genetic variations outside clock genes impact peripheral diurnal rhythms remains largely unknown. Here, we find that genetic variation contributes to different diurnal patterns of hepatic gene expression in both humans and mice. Nutritional challenges alter the rhythmicity of gene expression in mouse liver in a strain-specific manner. Remarkably, genetics and nutrition interdependently control more than 80% of rhythmic gene and enhancer-promoter interactions (E-PIs), with a noncanonical clock regulator, estrogen-related receptor gamma (ESRRγ), emerging as a top transcription factor during motif mining. Knockout of Esrrγ abolishes strain-specific metabolic processes in response to diet in mice, while single-nucleotide polymorphisms (SNPs) associated with rhythmic gene expression are enriched in E-PIs in steatotic human livers and correlate with lipid metabolism traits. These findings reveal a previously underappreciated temporal aspect of genetics-environment interaction in regulating lipid metabolic traits, with implications for individual variations in obesity-associated disease susceptibility and personalized chronotherapy.
