Outline of Final Research Achievements

Genome-wide DNA methylation analysis in early phase of Epstein-Barr virus infection revealed how aberrant DNA methylation could be induced around transcription start sites (TSSs) or in genebody and intergenic regions. DNA methylation occurred from the CpG shore or shelves to CpG islands. In expression analysis by RNA-sequencing, dynamic expression alteration of both host cells and EBV could be observed. These findings should be significant clues to elucidate the mechanisms of induction of aberrant DNA methylation.
