|
Hybridization protocol |
800 nanograms of genomic DNA was treated with sodium bisulfite by using the EZ DNA Methylation Kit (D5001, Zymo Research) following the manufacturer’s protocol. The bisulfite converted DNA was amplified, fragmented and hybridized to Infinium MethylationEPIC 850K Bead Chip (WG-317-1001, Illumina) using Illumina standard protocol.
|
Scan protocol |
Fluorescence intensities were captured using Illumina HiScan SQ (Illumina)
|
Description |
methylation profiling using bisulfite converted
|
Data processing |
Data was analysed using R version 3.4.1 (2017-06-30). Beta-values were extracted from ‘idat’ files by using the ‘Load’ module of the ‘Champ’ R package (v. 2.12.0), with quality control options set as default. The quality control step retained 759772 probes, which were used for further analysis. Probes overlapped with SNP (79662) and with a detection pvalue < 0.01 (3447), beadcount <3 in at least 5% of samples in one or more samples (2582) were eliminated. X or Y chromosomes probes (17432), non-cg probes (2915), and probes aligning to multiple locations (46) and unannotated probes were also removed from analysis. No background correction was carried out. SWAN normalisation was applied, with the ‘method’ option set to “minfi”. The SWAN normalized samples were assigned with respective genome coordinates based on probe name and manifest file (Illumina Inc., USA). The file 'matrix_signal_intensities.txt' includes: Unmethylated signal (B) and methylated signal (A) intensities
