Project description:The nuclear receptors (NRs) REV-ERBα and β, encoded by Nr1d1 and Nr1d2, link circadian rhythms and metabolism. REV-ERB lacks the canonical NR activation domain, and thus functions as a transcriptional repressor. Like other NRs, REV-ERBs can be regulated by ligands, including naturally occurring heme, which potentiate their repressive activity. Attempts to pharmacologically target REV-ERBs by the use of putatively specific synthetic agonists, particularly SR90096, have suggested a wide range of beneficial effects in healthy as well as diseased animal models and cell systems. For instance, Sulli et al. recently reported that REV-ERB activation by SR9009 is specifically lethal to cancer (stem) cells but not other cell types. Because REV-ERBs are core components of the molecular clock, the results were interpreted as a link between the body’s circadian timekeeping system and cancer. Moreover, increased energy expenditure after SR9009 administration decreases obesity in mice, and the reported activity of SR9009 as an exercise mimetic in skeletal muscle have resulted in online sales of the compound as a performance-enhancing drug, with advertisements reassuringly highlighting REV-ERBs as the molecular target (https://www.evolutionary.org/stenabolic-sr9009-review; https://www.simplyanabolics.com/sarms/sr9009-stenabolic/).

Project description:The circadian clock acts at the genomic level to coordinate internal behavioral and physiologic rhythms via the CLOCK-BMAL transcriptional heterodimer. Although the nuclear receptors REV-ERB? and ? have been proposed to contribute to clock function, their precise roles and importance remain unresolved. To establish their regulatory potential we generated comparative cistromes of both Rev-erb isoforms, which revealed shared recognition at over ~50% of their total sites and extensive overlap with the master clock regulator Bmal. While Rev-erb? has been shown to directly regulate Bmal expression, the cistromic analysis reveals a more profound connection between Bmal and Rev-erb? and ? regulatory circuits than previously suspected. Genes within the intersection of the Bmal and Rev-erb cistromes are highly enriched for both clock and metabolic functions. As predicted by the cistromic analysis, dual depletion of Rev-erb?/? function by creating double-knockout mice (DKOs) profoundly disrupted circadian expression of core clock and lipid homeostatic genes. As a result, DKOs show strikingly altered circadian wheel-running behavior and deregulated lipid metabolism. These data reveal an integral role of Rev-erb?/? in clock function as well as provide a cistromic basis for the integration of circadian rhythm and metabolism. Total RNA was obtained from livers of wild-type and Liver-specific Reverb alpha/beta double knockout mice at ZT 0, 4, 8, 12, 16, and 20.

Project description:We have reported that cold temperature challenge results in a dramatic decrease in levels of the transcriptional repressor, Rev-erb alpha. Performing Rev-erb alpha ChIP-seq on brown adipose from wildtype animals kept at thermoneutrality or cold-challenged (and using Rev-erb alpha KO brown adipose as a control), we were able to globally determine the genomic regions undergoing Rev-erb alpha-dependent de-repression.

Project description:Rev-erbα/β are druggable components of the molecular circadian clock. Rev-erb agonists can mitigate pressure overload-induced cardiac hypertrophy and myocardial infarction in mice, while Rev-erb antagonist increases myocardial ischemia-reperfusion tolerance ex vivo at the sleep-to-wake transitionHow cardiac Rev-erb regulates heart function has not been studied in vivo.

Project description:We report the genomic regions enriched for Rev-erb(beta) binding in WT mouse liver, in addition to the false positive regions enriched by ChIP for Rev-erb(alpha) in Rev-erb(alpha) KO liver. In conjunction with previously published data for Rev-erb(alpha) in GSE26345 (GSM647029, GSM647033, and GSM647034), we report the common and subtype specific cistromes for Rev-erb using a quantitative analysis method.

Project description:Circadian and metabolic physiology are intricately intertwined, as illustrated by Rev-erb , a transcription factor (TF) that functions both as a core repressive component of the cell autonomous clock and as a regulator of metabolic genes. Here we show that Rev-erb modulates the clock and metabolism by different genomic mechanisms. Clock control requires Rev-erb to bind directly to the genome at its cognate sites, where it competes with activating ROR TFs. By contrast, Rev-erb regulates metabolic genes primarily by recruiting the HDAC3 corepressor to sites to which it is tethered by cell type-specific transcription factors. Thus, direct competition between Rev-erb and ROR TFs provides a universal mechanism for self-sustained control of molecular clock across all tissues, whereas Rev-erb utilizes lineage-determining factors to convey a tissue-specific epigenomic rhythm that regulates metabolism tailored to the specific need of that tissue.
