Summary (written by the submitters)
The circadian rhythm in the murine liver governs the activity of numerous enhancers which in turn coordinates diurnal gene expression. This process is controlled by oscillating activities of specific transcription factors (TFs) and recruitment of co-regulators, including histone modifying enzymes and chromatin remodeling complexes. Several circadian controlled TFs interact with the SWI/SNF family of chromatin remodeling complexes to control chromatin accessibility.
Read the full summary ↓
To unravel the significance of SWI/SNF ATPase subunits in circadian chromatin remodeling, we mapped chromatin accessibility, SWI/SNF occupancy, and gene expression throughout a day in murine liver. We found remarkable remodeling during fasting-to-fed transitions, and a third of circadian enhancers exhibited circadian SWI/SNF occupancy and accessibility. Intriguingly, genetic disruption of either of the two mutually exclusive ATPases of SWI/SNF had minor effects on chromatin accessibility in circadian enhancers, indicating redundancy. However, simultaneous disruption of both ATPases caused a collapse of the chromatin landscape, liver damage and inflammation. This disruption abolishes rhythmic expression of metabolic genes without affecting oscillation of the core circadian clock. In summary, this suggests an indispensable role of SWI/SNF-mediated chromatin remodeling of enhancers for circadian transcriptomic rhythms and basic liver function.

Direct links to NCBI and ENA, no account and no request form. Pick by what you want to do: take the small processed table to look, the supplementary files to re-analyse, or the original raw data to start over.

1 · Just have a look

Processed table

The series matrix: one table of values per sample as the submitters processed it. The smallest download, and it opens in Excel or R. Start here to see what the data look like.

2 · Re-analyse it

Supplementary files

The count tables and other files the authors uploaded. Take only the samples you need, or the whole study as GSE266937_RAW.tar (it can run to tens of gigabytes).

3 · Start from the raw reads

Raw sequencing reads

The original FASTQ files, straight from the sequencer, held at ENA. Large, and you align them yourself, so only choose this if you need to re-process the study from scratch.

What the files usually look like: Look for peak files (.bed, .narrowPeak) and signal tracks (.bigWig) among the supplementary files; the raw reads are on ENA.

Also filed as BioProject PRJNA1108747 and SRA study SRP506237. Searching any of these in the dataset finder brings you back here.
