| Sample type |
SRA |

|
| Source name |
Sciatic nerves
|
| Organism |
Mus musculus |
| Characteristics |
strain: C57Bl6J
age: Post natal day 5-8
cell type: Schwann cells
medium: Schwann cell medium
treatment: no treatment
|
| Treatment protocol |
Schwann cells were isolated from scitaic nerves from C57Bl6J mice, and then either treated with SAMe or GNMT silenced by lentiviral vectors.
|
| Extracted molecule |
genomic DNA |
| Extraction protocol |
(1) After isolation, cultured Schwann cells were scraped, flash-frozen in liquid nitrogen, before pooling together for genomic DNA extraction using PureLINK Genomic Extraction kit from Invitrogen.
RRBS/MspI followed by a modified TruSeq DNA sample preparation kit (Illumina Inc.). Samples were multiplexed according to Illumina's recommendations and experimental design.

Basecalls performed using CASAVA version 1.8.2
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 mm9 (Mus musculus) reference genome using the BSMAP (http://rrbsmap.computational-epigenetics.org/) with the following parameters -s 12 -D C-CGG .
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: mm9
Supplementary_files_format_and_content: [Sample].call files contain location of the CpG, total read coverage on the C base, percentage of bisulfite converted Cs
Supplementary_files_format_and_content: (representing unmethylated Cs) and non-converted Cs (representing methylated Cs). The pipeline that aligns and calls for
