Treatment protocol Cell lines were grown either in normoxia (N) or hypoxia( H) for at least 3 days before collecting.
Growth protocol Cells were seeded in DMEM F12 media supplemented with N2, EGF, FGF and Heparin sulphate for 3 days.
Extracted molecule genomic DNA
Extraction protocol DNA methylation of cultured cells was performed using Infinium EPIC 850 array
Label Cy3, Cy5
Label protocol Standard Illumina protocol
Hybridization protocol Standard Illumina protocol
Scan protocol Standard Illumina protocol
Data processing DNA methylation of cultured cells was performed using Infinium EPIC array. We performed noob (Normal-exponential convolution using out-of-band probes) background correction (37) and dye bias correction using the minfi package (38). The DNA methylation score for each locus is presented as a beta ( ) value ( = (M/(M+U)) in which M and U indicate the mean methylated and unmethylated signal intensities for each locus, respectively. -values range from zero to one, with scores of zero indicating no DNA methylation and scores of one indicating complete DNA methylation. A detection p-value also accompanies each data point and compares the signal intensity difference between the analytical probes and a set of negative control probes on the array. Any data point with a corresponding p-value greater than 1x10-16 is deemed not to be statistically significantly different from background and was thus masked as NA . The genomic location of the EPIC probes was classified into those within CpG islands (CGI), in CGI shores (4kb regions flanking CGIs), or in open seas (> 4kb to the nearest CGIs) using UCSC genome table browser (hg38) CGI genomic annotation.
