| Source name |
cerebellum

| Organism |
Mus musculus |
| Characteristics |
strain: C57BL/6
age: 8Â week
tissue: cerebellum

| Extracted molecule |
genomic DNA |
| Extraction protocol |
The tissues for the technical replicates are from independent mouse, and at least two replicates are included in different assay as indicated. Genomic DNA (Qiagen, Cat#: 51306) were extracted according to the manufacturers’ instructions.
The sequencing libraries were constructed as described with minor modification. Briefly, genomic DNA with spike-in controls was glycosylated and oxidized using the kit from Wisegene (Cat#: K001). Then, the DNA was further directed to bisulfite conversion using the EZ DNA methylation Gold kit (Zymo Research) according to the instruction manual. The library was sequenced using Illumina HiSeq X Ten. Paired reads were mapped uniquely to the reference genome (mm10, UCSC) by Bismark. Efficient conversion of unmodified cytosine to uracil and efficient conversion of 5mC to 5caU/U were calculated by spiked M.SssI-treated lambda DNA.

| Data processing |
Paired reads were mapped uniquely to the reference genome (mm10, UCSC) by Bismark.The 5hmC level of the biological replicates were calculated in 1Mb regions throughout the genome
After PCR duplication remove, we calculated the 5hmC or 5mC level of each CpG sites. The processed bigwig files indicate the 5hmC and 5mC level in CpG sites coverd by more than 5 reads.
genome build: mm10
processed data files format and content: bigwig or text files with 5hmC or 5mC level or gene FPKM. 5hmC or 5mC level calculation is as follows: we counted the number of 'C' bases from sequencing reads as hydroxymethylated or methylated (denoted as NC) and the number of 'T' bases as unmodified (denoted as NT). The hydroxymethylation level or methylation level was estimated as NC/(NC + NT) in 1Mb windows. Bigwig files are available on the series record.
