Sample GSM2333856 Query DataSets for GSM2333856
Status Public on Dec 15, 2016
Title Chow-chow, rep2 (ChIP-Seq)
Sample type SRA
 
Source name Chow-chow, liver
Organism Mus musculus
Characteristics strain: C57BL/6J
chip antibody: H3K27ac (Abcam, catalog# #4729, lot# GR132150-1)
treatment: chow-chow
age: 24 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 genomic DNA
Extraction protocol ChIP-seq libraries of H3K27ac-enriched DNA 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).
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).
