Sample GSM7808605 Query DataSets for GSM7808605
Status Public on Mar 13, 2024
Title Hippocampus, K9me3-P65ID-pooled2_S11
Sample type SRA
 
Source name Brain
Organism Rattus norvegicus
Characteristics tissue: Brain
tissue region: Hippocampus
group: ID4
maternal treatment: ID
offspring age: P65
chip antibody: H3K9me3 (Diagenode, Cat.# C15410193)
Extracted molecule genomic DNA
Extraction protocol For ChIP-seq, chromatin was fixed with 1% formaldehyde solution, fragmented, and precipitated with H3K9me3 antibody. DNA was quantified using the PicoGreen dsDNA Assay Kit.
Library preparation for ChIP-seq was completed using ThruPLEX® DNA-Seq (Rubicon Genomics) kit. Libraries were assessed for quality using electrophoresis on an Agilent Bioanalyzer (Agilent) and size-selected for 200~800 bp fragments.
 
Library strategy ChIP-Seq
Library source genomic
Library selection ChIP
Instrument model Illumina HiSeq 2500
 
Description annotated_ID_peaks_chipseq.txt
Data processing Raw sequencing reads were aligned to the rat reference genome (rn6) using HISAT2 (Kim et al., 2019).
MACS was utilized to assess sites of H3K9me3 histone modification (peaks).
diffReps (Shen et al., 2013) was run on the processed samples to find differential sites for the comparisons to the IS control group (ID, IDch, or ISch vs IS).
The atacseq.txt and chipseq.txt files are the annotation peak lists obtained from MACS software. The fold change for each peak is computed as the ratio of the read count in the peak to the maximum of the local and global lambda values.
Local Lambda: MACS2 computes a local lambda value for each peak, which is a measure of the local background noise around the peak.
Global Lambda: MACS2 also computes a global lambda value, which is a measure of the background noise across the entire genome.
Assembly: rn6
Supplementary files format and content: tab-delimited text peaks file
