Integrated epigenomic analyses of enhancer as well as promoter regions in gastric cancer


ABSTRACT: We performed H3K27ac ChIP-seq data in seven gastric cancer cell lines to investigate the functional significance of epigenetic changes at distal regulatory regions H3K27ac ChIP-seq profiling of gastric cancer cell lines were generated by deep sequencing, in each seven samples, using Illumina GAIIx and Hiseq-2000

Abnormal DNA methylation is an epigenetic mechanism that promotes gastric carcinogenesis. While the abnormal methylation at promoter regions has been characterized for many genes, the function of DNA methylation marks at distal regulatory regions in gastric cancer remains poorly described. Here, we performed RNA-seq, MBD-seq, and H3K27ac ChIP-seq on gastric tissues and cell lines to understand the epigenetic changes in the distal as well as the proximal regulatory regions. In total, 257,651 sign  ...[more]
