A genome-wide analysis reveals the MeCP2-dependent regulation of genes in BGC-823 cells.

ABSTRACT: Methyl-CpG-binding protein 2 (MeCP2) epigenetically modulates gene expression through genome-wide binding to methylated CpG dinucleotides. This study aimed to evaluate the effect of MeCP2 on the global gene expression profile of human gastric adenocarcinoma to determine the potential molecular mechanism of MeCP2. To identify the gene targets of MeCP2 in gastric cancer cells, we combined the expression microarray and chromatin immunoprecipitation approaches of MeCP2, followed by sequencing (ChIP-seq) to define the MeCP2-binding sites across the whole genome. The methylation levels of the promoters in BGC-823 cells were downloaded from the National Center for Biotechnology Information Gene Expression Omnibus database (GSM1093053). A total of 5,684 ChIP-enriched peaks were identified by compa
