| Sample type |
SRA |

|
| Source name |
murine embryonic stem cell
|
| Organism |
Mus musculus |
| Characteristics |
developmental stage: E14
genotype/variation: scr
antibody: Rabbit anti-m6A (Synaptic, 202003)
|
| Treatment protocol |
RNA was fragmented and subject to immunoprecipitation with a m6A specific antibody.
|
| Growth protocol |
E14 murine embryonic stem cell was cultured in Dulbecco’s modified Eagle’s medium containing 10% fetal bovine serum, 1% none essential amino acid, 0.1% beta-mercaptoethanol, 100u/ml penicillin/ Streptomycin and 1000u LIF.
|
| Extracted molecule |
total RNA |
| Extraction protocol |
Total RNAs from mESCs were isolated using Trizol reagent according to the manufacturer’s instruction (Life technology, 15596018). Polyadenylated RNAs were extracted by oligodT beads (NEB, S1419S), followed by removal of contaminated rRNA with RiboMinus transcriptome isolation kit (Life technologies, A15026).
RNA libraries were prepared for sequencing using standard Illumina protocols

Library strategy: m6A-seq
Basecalls performed using CASAVA version 1.4
m6A-seq datas were aligned to the mm9 genome assembly using Tophat2 with the following parameters:tophat2 -p 8 -G Mus_musculus.Ensembl.NCBIM37.65.gtf --max-multihits 1 --prefilter-multihits -o m6A_thout mm9_assemblies m6A.fq
RNA-seq datas were aligned to the mm9 genome assembly using Tophat2 with the following parameters:tophat2 -p 8 -G Mus_musculus.Ensembl.NCBIM37.65.gtf -o RNA-seq_thout mm9_assemblies RNA-seq.fq
m6A peaks were called by exomePeak 2.13 package of of Bioconductor under default parameters.
Transcriptome is assemblied using cufflinks;differential expressed genes were identified by cuffdiff.
Mapped m6A reads were transfer to bedgraph files for visualization using bedtools.
FPKM value of Ensembl genes were calculated by cufflinks.
Genome_build: mm9
Supplementary_files_format_and_content:
bed files include m6A peak lists identified by exomePeaks;and bg files include the averaged m6A enriched density.
tab-delimited text file include the FPKM values of Ensembl genes in Mus musculus genome;
