Methylation of gene specific CpGs in lung cancer cell lines. (A) CpG sites are annotated depending on the gene specific orientation in TSS1500 (−1500 to −200 bp), TSS200 (−200 bp to TSS), 5′-UTR, 1st exon, gene body and 3′-UTR. (B) Methylation levels of CpG islands and flanking N-and S-shores were analyzed in NHBEC and in the lung cancer cell line H322 by 450 K bisulfite bead chip arrays according to the gene specific annotation.
