Chow, rep2 (RNA-Seq) |
| Sample type |
SRA |
| |
|
| Source name |
Chow, liver
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6J
treatment: chow
age: 19 weeks
|
| Treatment protocol |
C57BL/6J mice (Jackson Laboratory) were fed either a HFD (D12327, Research Diet, 40% fat by calories) or chow diet (NIH-31, Zeigler Brothers Inc., 8% fat by calories) for seven weeks from 12 weeks of age (groups termed HFD and Chow, respectively). After seven weeks, half of the mice where sacrificed by CO2 narcosis followed by cervical dislocation, livers were dissected and processed for RNA purification, nuclei isolation or frozen in liquid nitrogen for subsequent studies. Blood samples were taken as indicated and processed for metabolic measurements. The other half of the animals continued on a chow diet (termed HFD-chow and Chow-chow) for an additional five weeks

| Extracted molecule |
total RNA |
| Extraction protocol |
5 mg of liver tissue were homogenized using UltraThorax and RNA was purified using TRIzol-RNA lysis reagent (ThermoFisher) according to manufacturer’s instructions. Sample was prepared for sequencing using polydT-enriched cDNA synthesis.
Purified RNA was subjected to either polydT-enriched cDNA synthesis before sequencing and sequenced on the Illumina platform according to the manufacturer’s instructions. ChIP-seq and libraries of H3K27ac-enriched DNA and DHS-seq libraries were constructed according to the manufacturer's instructions (Illumina) as described in (Nielsen R, Mandrup S, 2014 Genome-Wide Profiling of Transcription Factor Binding and Epigenetic Marks in Adipocytes by ChIP-seq. Methods in Enzymology 2014, Vol. 537, pp. 261-279).

Aligment to mm9 using STAR
Differential gene expression and H3K27ac binding identified using DESeq2.
Gene ontology analysis using PANTHER.
To quantify exon and intron RNA reads the iRNA pipeline was used (Madsen, J. G. et al. iRNA-seq: computational method for genome-wide assessment of acute transcriptional regulation from total RNA-seq data. Nucleic acids research, doi:10.1093/nar/gku1365 (2015).
Pathway analysis of intron-regulated genes using the curated reactome database (Croft, D. et al. The Reactome pathway knowledgebase. Nucleic acids research 42, D472-477, doi:10.1093/nar/gkt1102 (2014).Fabregat, A. et al. The Reactome pathway Knowledgebase. Nucleic acids research 44, D481-487, doi:10.1093/nar/gkv1351 (2016)).
