Sample GSM2043519 Query DataSets for GSM2043519
Status Public on Feb 02, 2017
Title MKS_322K_RRBS
Sample type SRA
 
Source name Liver
Organism Mus musculus
Characteristics tissue: Liver
genotype: MAT1A KO
age: 10 month
treatment: SAMe supplementation
Growth protocol Mice were breed and housed at the Animal Facility of CIC bioGUNE under controled conditions according to the animal care international gidelines.
Extracted molecule genomic DNA
Extraction protocol DNA was extracted from the livers using AllPrep DNA/RNA Mini Kit
RRBS/MspI+TaqαI, followed by a modified NEXTflex™ Bisulfite-Seq Kit (Illumina Compatible, Bioo Scientific Corp Catalog #5119-01). Samples were multiplexed according to Illumina's recommendations and experimental design.
 
Library strategy Bisulfite-Seq
Library source genomic
Library selection Reduced Representation
Instrument model Illumina HiScanSQ
 
Data processing Basecalls performed using CASAVA version 1.8.2
Individual FASTQ files for each sample were merged prior to the quality control & filtering steps
Reads were filtered from the adapter sequences and their quality score using trim_galore software. (http://www.bioinformatics.babraham.ac.uk/projects/trim_galore/) and only are retained those with at least 20 phred quality score.
Reads were mapped to mm10 (Mus musculus) reference genome using the Bismark (http://www.bioinformatics.babraham.ac.uk/projects/bismark/) allowing two alignment mismatches (n 2).
Resulting SAM aligment files were sorted to be used in as input in further steps.
In order to call methylation score for a base position, we required that read bases aligning to that position have at least 5X coverage. We use methylKit to compute methylation ratios and differential methylation analysis (http://code.google.com/p/methylkit/)
Genome_build: mm10
Supplementary_files_format_and_content: Differentially methylated regions (DMR) table obtained from Methylkit processing of the SAM files yieldedby Bismark alignment. Each table representes the following parameters: Chromosome (chr), start and end coordinates of the methylated region (start, end), strand location (strand), probability value "pvalue", adjusted p-value "qvalue", differential methylation score "meth.diff". Only regions with a meth.diff score over 20 or under -20, and a qvalue under 0.05, where considered as differentially methylated (Hyper- or Hypo- methylated respectively).
