Methylation sequencing  data of Control
Genomic DNA was extracted from the NAc using the QIAamp DNA Mini kit (Qiagen, Hilden, Germany). DNA was sheared and then purified using the QIAquick PCR purification kit, and libraries were constructed using the Illumina library preparation kit. Thereafter, the QIAquick PCR purification kit was used to purify the libraries, and the EpiTect bisulfite kit (Qiagen, Hilden, Germany) was suitable for bisulfite conversion. Bisulfite converted libraries were amplified using PfuTurbo HotStart DNA Polymerase (Agilent Technologies, CA, USA), size selected (200-300 bp), quantified using qPCR, and run through the Illumina HiSeq 2000 platform as previously described
