(Submitter supplied) We demonstrate that dCas9-SunTag-DNMT3A dramatically increased CpG methylation at the HOXA5 locus in human embryonic kidney 293T cells (HEK293T). Furthermore, using a single sgRNA, dCas9-SunTag-DNMT3A was able to methylate a 4.5 kb genomic region and repress HOXA5 gene expression. Reduced representation bisulfite sequencing (RRBS) and RNA-seq showed that dCas9-SunTag-DNMT3A methylated regions of interest with minimal impact on the global DNA methylome and transcriptome.

(Submitter supplied) DNA methylation is a covalent modification of the genome that plays important roles in genome regulation and vertebrate development. Although detection of this modification in the genome has been possible for several decades, the ability to deliberately and specifically manipulate local DNA methylation states  in the genome has been extremely limited. Consequently, this has impeded the direct determination of the consequence of DNA methylation on transcriptional regulation and transcription factor binding in the native chromatin context. more...

(Submitter supplied) Understanding genomic functions requires site-specific manipulation of loci via efficient protein effector targeting systems. However, few approaches for targeted manipulation of the epigenome are available in plants. Here, we adapt the dCas9-SunTag system to engineer targeted gene activation and DNA methylation in Arabidopsis. We demonstrate that a dCas9-SunTag system utilizing the transcriptional activator VP64 drives robust and specific activation of several loci, including protein coding genes and transposable elements, in diverse chromatin contexts. more...

(Submitter supplied) Fusion of active protein domains to the nuclease-deficient clustered regularly interspaced short palindromic repeat (CRISPR) associated protein 9 (dCas9) has been widely used for epigenome editing, but the specificities of these engineered proteins have still not been fully investigated. Targeted methylation of specific gene loci offers a direct approach to perturb DNA methylation-associated biological processes. more...

(Submitter supplied) We report the generation of CRISPR-dCas9 DNA methyltransferases to mediate targeted DNA methylation. Using the dCas9-BFP-DNMT3A and dCas9-BFP-DNMT3B methyltransferases, we have demonstrated that these two methyltransferase can mediate targeted methylation in three human genes tested: uPA, TGFBR3, and CDKN2A in human HEK293T cells. We also showed that these methyltransferases could mediate gene inhibition.

(Submitter supplied) Rewriting of the epigenome has risen as a promising alternative to gene editing for precision medicine. In nature, epigenetic silencing can result in complete attenuation of target gene expression over multiple mitotic divisions. However, persistent repression has been difficult to achieve using targeted systems. Here, we report that robust and persistent epigenetic memory required both a DNA methyltransferase (DNMT3A-dCas9) and a histone methyltransferase (Ezh2-dCas9 or KRAB-dCas9). more...

(Submitter supplied) Epigenome editing is a promising technology, potentially allowing the stable reprogramming of gene expression profiles without alteration of the DNA sequence. Targeted DNA methylation has been successfully documented by many groups for silencing of selected genes, but recent publications have raised concerns regarding its specificity. In the current work, we developed new EpiEditors for programmable DNA methylation in cells with a high efficiency and improved specificity. more...

(Submitter supplied) The human genome is folded into regulatory units termed ‘topologically-associated domains’ (TADs), within which the majority of gene-enhancer interactions occur. Genome-wide studies support a global role for the insulator protein CTCF in mediating chromosomal looping and the topological constraint of TAD boundaries3,4. However, the impact of individual insulators on enhancer-gene interactions and transcription remains poorly understood. more...

(Submitter supplied) Purpose: DNA methyltransferase 3A (DNMT3A) mediates de novo DNA methylation. Mutations in DNMT3A are associated with hematological malignancies, most frequently acute myeloid leukemia. DNMT3A mutations are hypothesized to establish a pre-leukemic state, rendering cells vulnerable to secondary oncogenic mutations and malignant transformation. However, the mechanisms by which DNMT3A mutations contribute to leukemogenesis are not well-defined. more...
