CUT&RUN analysis for NOP16-mediated H3K27me3 alteration in MDA-MB231 cells [CUT&RUN-seq]

ABSTRACT: The goal of CUT&RUN-seq is to identify the global alteration of H3K27me3 levels by NOP16 overexpression or deletion in triple negative breast cancer cell line MDA-MB231 cells. Three (or Two) biological replicates were assigned for each group and in total 6 groups were prepared for these CUT&RUN-seq libraries. We mapped about 20 million reads per sample to hg38 human reference genome, and counted and normalized each reads number and identified H3K27me3 distribution.

Identification of chromatin states during zebrafish gastrulation using CUT&RUN and CUT&Tag

Project description:Here we describe successful implementation of CUT&RUN for profiling protein-DNA interactions in zebrafish embryos. We apply modified a CUT&RUN method to generate high resolution maps of enrichment for H3K4me3, H3K27me3, H3K9me3, and RNA polymerase II during zebrafish gastrulation. Using this data, we identify a conserved subset of developmental genes that are enriched in both H3K4me3 and H3K27me3 during gastrulation, and we demonstrate the increased effectiveness of CUT&RUN for detecting protein enrichment at repetitive sequences with reduced mappability. Our work demonstrates the power of combining CUT&RUN with the strengths of the zebrafish system to better understand the changing embryonic chromatin landscape and its roles in shaping development.

Bulk Cut&run and Cut&tag

Project description:We generated bulk Cut&run data with antibodies agains H3K27me3 in primary mouse OPCs and OPC model cell line Oli-neu, and with antibodies agains H3K27ac in Oli-neu cell line with addition of BSA at various steps of the protocol. These datasets were used as benchmarks for the scCUT&Tag data of the mouse brain.

CUT&RUN-seq of H3K4me3, H3K27me3 and H3K27ac in mll2wt and mll2[Y2602A] mESC

Project description:CUT&RUN-seq of H3K4me3, H3K27me3 and H3K27ac in mouse ESCs carrying a homozygous point mutation in the catalytic domain of mll2[Y2602A]. CUT&RUN was performed according to Skene & Henikoff, 2017 and purified DNA was using for library preparation with NEBNext DNA Ultra II kit (NEB E7645S; input: 5 ng of DNA). Libraries were multiplexed and sequenced on a NextSeq500 (Paired-End; read length 40). Each sample is present in 3 biological replicates.

Low-input chromatin profiling in Arabidopsis endosperm using CUT&RUN

Project description:Endosperm is an essential seed tissue with a unique epigenetic landscape. During endosperm development, differential epigenetic regulation of the maternal and paternal genomes plays important roles in regulating gene expression, especially at imprinted genes. Profiling the endosperm epigenetic landscape on a genome-wide scale is challenging due to its small size, mode of development, and close association with maternal tissue. Here, we applied a low input chromatin profiling method, CUT&RUN (cleavage under targets and release using nuclease), to profile parental-specific chromatin modifications using low numbers of Arabidopsis endosperm nuclei. We demonstrate that CUT&RUN generates genome-wide H3K27me3 landscapes with high sensitivity, specificity and reproducibility using around 20,000 endosperm nuclei purified by flow cytometry and fluorescence-activated cell sorting. H3K27me3 peaks identified by CUT&RUN and previous ChIP (chromatin immunoprecipitation) approaches were largely overlapping, with some distinctions in heterochromatin. The versatility and simplicity of CUT&RUN makes it a viable alternative to ChIP, which requires greater amounts of starting material, and will enable the study of tissue or even cell-type specific epigenomes in Arabidopsis and other plant species.

Cut&Run in Drosophila melanogaster control, mutant and knockdown ovaries

Project description:H3K27me3 profiles using Cleavage under targets and Release using nuclease (Cut&Run) in control and KD Drosophila melanogaster ovaries. We examined the impact on chromatin profiles in Drosophila melanogaster ovaries in which the lid, the Sin3a, the Snr1 or the mod(mdg4) gene have been selectively knocked down by tissue-specific shRNA expression. We additionally explored H3K27me3 and H3K9me3 in control and dhd mutant ovaries either carrying or not a transgene.
