Epigenetic editing and epi-drugs: a combination strategy to simultaneously target KDM4 as a novel anticancer approach.

ABSTRACT: KDM4-A/B/C, preferentially demethylating di- and tri-methylated lysine 9 on histone H3, are overexpressed in cancers and considered interesting therapeutic targets. Consequently, KDM4 inhibitors have been developed to block their enzymatic activity. However, the potential lack of specificity of such small molecules (epi-drugs) may contribute to dose-limiting toxicities. In the pursuit of more specific interventions, epigenetic editing (epi-editing) has emerged as a powerful tool to modulate gene expression by modifying the epigenetic profile of specific genomic locations. The recently developed CRISPRoff (dCas9 fused to DNMT3A/3L and KRAB), guided by sgRNAs, is successfully used for gene repression by introducing methylation of DNA and (indirectly) of histones at the targeted genomic regio
