Dissecting the Rev-erbα Cistrome and the Mechanisms Controlling Circadian Transcription in Liver

Rev-erbα is identified as a primary driver of circadian enhancers in mouse liver, regulating gene expression in opposing phases.

• Circadian clocks coordinate rhythmic gene expression to maintain metabolic balance.
• Functional enhancers of circadian genes are influenced by phase-specific transcription factors.
• Rev-erbα competes with RORα for binding to DNA, affecting the oscillation of core clock genes.
• Metabolic clock-controlled genes are regulated by the NCoR/HDAC3 complex at enhancers associated with Rev-erbα.
• The binding competition between Rev-erbα and RORα ensures consistent clock control in all tissues.
• Tissue-specific recruitment mechanisms allow Rev-erbα to tailor epigenomic rhythms for specific metabolic needs.
