Extracted molecule |
genomic DNA |
Extraction protocol |
Genomic DNA was isolated from the fibroblast cell stock using phenol-chloroform extraction protocol, precipitated using ethanol precipitation protocol and resuspended in 1X TE buffer. In brief, genomic DNA were fractionated by sonication, ligated to an adaptor and modified with bisulfite conversion protocol. It was then amplified with a PCR scheme designed to enrich AluYa5 and AluYb8, and finally size-fractionated using the E-gel Precast Agarose Electrophoresis System (Life Technologies). The prepared libraries were sequenced on the Ion-Torrent PGM platform.

Data processing |
Trimming raw sequence reads smaller than 100-bp long out of a fastq file with a custome-made Python script Mapping raw sequence reads to a custome-made database containing bisulfite-converted AluY sequences using Bowtie2 Grouping a number of sequence reads to each AluY5/Yb8 locus using a custome-made Perl script Trimming out raw sequence reads for a given Alu locus that do not have a sufficient sequence coverage for DNA methylation analyses Running a batch analysis of BiQanalyzerHT for DNA methylation levels of AluYa5/Yb8 with a custom-made Perl script Genome_build: hg19 Supplementary_files_format_and_content: BED files showing methylation level of each sequenced locus
