This research aimed to repress target genes by modulating their expression through rewriting of aberrant epigenetic landscapes, including DNA methylation and histone post-translational modifications, utilizing epigenetic repressor domains. The epigenetic repressor domains included KRAB, DNMT3A, UHRF1 and CSD, which were delivered via the epigenetic editing tools ZFs, TALEs and the CRISPR/dCas9 system. Our findings suggest that a combination of multiple epigenetic repressor domains targeting epigenetic marks involved in epigenetic cross-talk significantly repressed target genes.
