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

ABSTRACT: To understand epigenetic changes in the distal regulatory as well as proximal regions, we performed RNA-seq, MBD-seq, and H3K27ac ChIP-seq on gastric tissues and cell lines MBD sequencing of normal tissue (n), purified gastric cancer (sc), and cultured gastric cancer cell (dc) were generated by deep sequencing, in five samples from three patients (csc1, csc2, csc3) and two replicates (csc1_sc2, csc1_sc3), using Illumina GAIIx.

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]

Vascular histone deacetylation by pharmacological HDAC inhibition [TSA, ChIP-seq]

Project description:HDAC inhibitors are thought to regulate gene expression by post-translational modification of histone as well as non-histone proteins. Often studied at single loci, increased histone acetylation is the paradigmatic mechanism of action, however, little is known of the extent of genome-wide changes of the mammalian genome when stimulated by the hydroxamic acids, TSA and SAHA. In primary human vascular endothelial cells we map the chromatin modifications, histone H3 acetylation of lysine 9 and 14 (H3K9/14ac) using chromatin immunoprecipitation (ChIP) coupled with massive parallel sequencing (ChIP-seq). Since acetylation mediated gene expression is often associated with modification of other lysine residues we also examined H3K4me3 and H3K9me3 as well as changes in CpG methylation (CpG-seq). Genome-wide mRNA sequencing indicates the differential expression of about 30% of genes, with almost equal numbers being up- and down- regulated. We observe deacetylation conferred by TSA and SAHA that are associated with decreased gene expression. Histone deacetylation is associated with the loss of p300/CBP binding at gene promoters. This study provides an important framework for HDAC inhibitor function in vascular biology and a comprehensive description of genome-wide deacetylation. HAEC ChIP-seq profiles for 3 histone marks of TSA treated and control samples were generated by deep sequencing, in triplicate, using Illumina GAIIx.
