CUT&RUN-seq of H3K9me3, H4K20me3 or H3K4me3 in mESC after epigenetic editing and upon release of the trigger

ABSTRACT: Enrichment of histone marks was assessed by CUT&RUN-sequencing after epigenetic editing with dCas9::KRAB (or dCas9::GFP as a control) and subsequently upon release of the trigger. Samples were collected after 7 days of DOX induction (epigenetic editing) and after 4 and 7 days of DOX washout (release of the trigger).

ATAC-seq of ESC or in vitro differentiated endoderm cells after epigenetic editing and upon release of the trigger

Project description:Chromatin accessibility was assayed in ESC after epigenetic editing with dCas9::KRAB (or dCas9::GFP as a control) and subsequently in ESC and Endoderm differentiated cells upon release of the trigger. Samples were collected in two biological replicates after 7 days of DOX induction in ESC (epigenetic editing) and after 7 days of DOX washout (release of the trigger) in ESC and Endoderm cells.

CRISPR screen to identify regulators of epigenetic memory in ESC

Project description:A genome-wide CRISPR screen was combined with a tdTomato reporter-based epigenetic memory assay to identify factors that erase epigenetic memory in ESC. After introducing genome wide perturbation and dCas9::KRAB-mediated epigenetic editing of the Esg1-tdTomato reporter, the trigger was released and cells that maintained the silencing sorted at FACS. Samples were collected out of sorted tdTomato negative (TOMminus) and positive (TOMplus) cells after 6 days of DOX treatment (epigenetic editing) and 3 or 7 days of DOX washout (release of the trigger), using a gating strategy to separate the bottom 2.5% negative cells (2.5%gate) and cells ranging from mildly to fully repressed (widegate).

ATAC-seq of wildtype or Dppa2 knockout ESC upon release of the epigenetic editing trigger

Project description:Chromatin accessibility was assayed in wildtype or Dppa2 knockout ESC after 26 days of release of the trigger imposed by epigenetic editing. Samples were collected in two clonal knockout and wildtype lines after sorting at FACS of cells which maintained a repressive Esg1-tdTomato (TOMneg) reporter expression after 26 days of DOX washout (release of the trigger).

ATAC-seq of HEK293 cells with Alu-motif targeted dCas9GFP

Project description:HEK293 cells were selected and subcloned for doxycyclin (DOX) and trimethoprim (TMP) inducible dCas9GFP and a guide RNA molecule targeting an EGA enriched Alu-motif (EEA-g1). Cells were treated with DOX and TMP for three days to induce dCas9GFP expression and ATAC-seq samples were collected from treated and non-treated cells to analyse the effect of targeting the motif with dCas9.

Frequent and Transient Acquisition of Pluripotency During Somatic Cell Trans-Differentiation with iPSCs Reprogramming Factors (WGBS)

Project description:Recent reports have proposed a new paradigm for obtaining mature somatic cell types from fibroblasts without going through a pluripotent state, by briefly expressing canonical iPSC reprogramming factors Oct4, Sox2, Klf4 and c-Myc (abbreviated as OSKM), in cells expanded in lineage differentiation promoting conditions. Here we apply genetic lineage tracing for endogenous Nanog, Oct4 and X chromosome reactivation during OSKM induced trans-differentiation, as these molecular events mark final stages for acquisition of induced pluripotency. Remarkably, the vast majority of reprogrammed cardiomyocytes or neural stem cells derived from mouse fibroblasts via OSKM mediated trans-differentiation were attained after transient acquisition of pluripotency, and followed by rapid differentiation. Our findings underscore a molecular and functional coupling between inducing pluripotency and obtaining “trans-differentiated” somatic cells via OSKM induction, and have implications on defining molecular trajectories assumed during different cell reprogramming methods. WGBS (Whole-Genome-Bisulfite-sequencing) were measured during conversion of mouse embryonic fibroblasts to neural stem cells using OSKM trans-differentiation method, as well as in mouse emrbyonic fibroblasts, and mouse ESCs.

ChIP-MS reveals the local chromatin composition by label-free quantitative proteomics

Project description:Chromatin immunoprecipitation (ChIP) has been a cornerstone for epigenetic analyses over the last decades, but even coupled to sequencing approaches (ChIP-seq), it is ultimately limited to one protein at a time. In a complementary effort, we here combined ChIP with label-free quantitative (LFQ) mass spectrometry (ChIP-MS) to interrogate local chromatin compositions. We demonstrate the versality of our approach at telomeres, with transcription factors, in tissue and by dCas9-driven locus-specific enrichment.

MiSeq paired-end sequencing of HEK293T cells stably expressing a Cas9/gRNA-dependent editable reporter vector to test novel nucleobase-editing techniques

Project description:The goal of these experiments were to test the on-target and target-adjacent editing efficiencies of different single-nucleobase editing systems. Previous studies have shown that tethering DNA mutating enzymes to Cas9-nickase-UGI complexes results in editing of chromosomal DNA. However, these editing events encompass undesirable target-adjacent nucleobase edits. Here, we characterize a novel approach that reduces the frequency of target-adjacent editing while maintaining a high level of on-target editing.

CRISPR Display: A modular method for locus-specific targeting of long noncoding RNAs and synthetic RNA devices in vivo [RNA-Seq]

Project description:Noncoding RNAs (ncRNAs) comprise an important class of natural regulators that mediate a vast array of biological processes, including the modulation of chromatin architecture. Moreover, artificial ncRNAs have revealed that the functional capabilities of RNA are extremely broad. To further investigate and harness these capabilities, we developed CRISPR-Display ("CRISP-Disp"), a targeted localization strategy that uses Cas9 to deploy large RNA cargos to specific DNA loci. We demonstrate that exogenous RNA domains can be functionally appended onto the CRISPR scaffold at multiple insertion points, allowing the construction of Cas9 complexes with RNAs nearing one kilobase in length, with structured RNAs, protein-binding cassettes, artificial aptamers and pools of random sequences. CRISP-Disp also allows the simultaneous multiplexing of disparate functions at multiple targets. We anticipate that this technology will provide a powerful method with which to ectopically localize functional RNAs and ribonuceloprotein complexes at specified genomic loci. Whole cell poly(A) selected RNA seq, from HEK293FT cells bearing lentivirally-integrated Gaussia and Cypridina luciferase reporter loci. Cells were transiently transfected with dCas9~VP64 alone, or with dCas9~VP and one of several modified sgRNAs,each targeting the Gaussia reporter.
