Title |
WT_661K_RRBS |
Sample type |
SRA |
|
|
Source name |
Liver
|
Organism |
Mus musculus |
Characteristics |
tissue: Liver genotype: MAT1A WT age: 10 month treatment: no treatment
|
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.

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).
