Decitabine disrupts EBV genomic epiallele DNA methylation patterns around CTCF binding sites to increase chromatin accessibility and lytic transcription in gastric cancer

Abstract excerpt

ABSTRACT Epstein-Barr virus (EBV) is associated with 10% of human gastric carcinomas, which are distinguished by a CpG island methylator phenotype. In gastric carcinoma tumors and cell lines, the EBV genome also exhibits a high degree of 5-methyl cytosine (5mC) marks, which are propagated by host DNA methyltransferases (DNMT) with each cell cycle. Therefore, we sought to determine the effect of DNMT inhibition by...
