(Submitter supplied) Mammalian circadian rhythms are based on coupled transcriptional-translational feedback loops driven by the transcription factors CLOCK and BMAL1. Chromatin remodeling mechanisms are essential for the proper timing and extent of circadian gene expression. We report that the S-adenosylhomocysteine (SAH) hydrolysing enzyme AHCY binds to CLOCK-BMAL1 at chromatin and drives circadian transcription by promoting cyclic H3K4 trimethylation and recruitment of BMAL1 to chromatin.

(Submitter supplied) The mammalian circadian clock relies on the master genes CLOCK (CLK) and BMAL1 and drives rhythmic gene expression to regulate biological functions under circadian control. We recently uncovered a surprising disconnect between the rhythmic binding of CLK:BMAL1 on DNA and the transcription of its target genes, suggesting that they are regulated by as yet uncharacterized mechanisms. Here we show that rhythmic CLK:BMAL1 DNA binding promotes rhythmic chromatin opening. more...

(Submitter supplied) We found that a H3K4 specific histone methyltransferase MLL1, a mammalian homologue of Drosophila trithorax, is essential for circadian transcription. MLL1 is in a complex with CLOCK:BMAL1 and contributes to their rhythmic recruitment to circadian promoters and cyclic H3K4 tri-metylation. To analyze the function of MLL1 on circadian gene regulation, we performed comparative microarray analysis of global gene expression levels in WT and MLL1-deficient MEF, at two different circadian time points (CT18 and CT30). more...

(Submitter supplied) Over the past decade, genome-wide assays have underscored the broad sweep of circadian gene expression. A substantial fraction of the transcriptome undergoes oscillations in many organisms and tissues, which governs the many biochemical, physiological and behavioral functions under circadian control. Based predominantly on the transcription feedback loops important for core circadian timekeeping, it is commonly assumed that this widespread mRNA cycling reflects circadian transcriptional cycling. more...

(Submitter supplied) Using chromatin immuno-precipitation (ChIP) combined with deep sequencing (ChIP-seq) we obtained a time resolved and genome-wide map of BMAL1 binding in mouse liver, which allowed to identify over two thousand binding sites with peak binding narrowly centered around Zeitgeber time (ZT) 6. Annotation of BMAL1 targets confirms carbohydrate and lipid metabolism as the major output of the circadian clock in mouse liver. more...

(Submitter supplied) The mammalian circadian clock involves a transcriptional feedback loop in which CLOCK and BMAL1 activate the Period and Cryptochrome genes, which then feedback and repress their own transcription. We have interrogated the transcriptional architecture of the circadian transcriptional regulatory loop on a genome scale in mouse liver and find a stereotyped, time-dependent pattern of transcription factor binding, RNA polymerase II (RNAPII) recruitment, RNA expression and chromatin states. more...

(Submitter supplied) Mammals rely on a network of circadian clocks to control daily systemic metabolism and physiology. The central pacemaker in the suprachiasmatic nucleus (SCN) is considered hierarchically dominant over peripheral clocks, whose degree of independence, or tissue-level autonomy, has never been ascertained in vivo. Using arrhythmic Bmal1-null mice, we generated animals with reconstituted circadian expression of BMAL1 exclusively in the liver (Liver-RE). more...

(Submitter supplied) The mammalian circadian clock system is made up of individual cell and tissue clocks that function as a coherent network, however it remains unclear which rhythmic functions of the liver clock are autonomous or rely on clocks in other tissues. Here, using mice which only have a functioning liver clock, we investigate the autonomous vs non-autonomous reatures of the liver clock and diurnal rhythmicity in the liver

Following H19 knockdown, we observed extensive genome-wide mthylation pattern changes relative to siCon cells, with some genes showing incresed methylation, others showing decreased methylation, and a third group with no significant change.
