Project description:In order to determine that CUT&Tag is similar to known DUX ChIP-seq, we performed CUT&Tag with a mCherry-tagged DUX (with the mCherry antibody). Once confirmed, we pewrformed CUT&Tag for other DUX derivatives with their mCherry tag Then, we performed CUT&Tag for H3K9ac, which is known to globally increase in 2-cell-like cells, which occurs after DUX expression, and CUT&Tag for SMARCC1, a subunit of the SWI/SNF complex

Project description:We developed scNanoSeq-CUT&Tag, a streamlined method by adapting a modified CUT&Tag protocol to Oxford Nanopore sequencing platform for efficient chromatin modification profiling at single-cell resolution. We firstly tested the performance of scNanoSeq-CUT&Tag on six human cell lines: K562, 293T, GM12878, HG002, H9, HFF1 and adult mouse blood cells, it showed that scNanoSeq-CUT&Tag can accurately distinguish different cell types in vitro and in vivo. Moreover, scNanoSeq-CUT&Tag enables to effectively map the allele-specific epigenomic modifications in the human genome andallows to analyze co-occupancy of histone modifications. Taking advantage of long-read sequencing,scNanoSeq-CUT&Tag can sensitively detect epigenomic state of repetitive elements. In addition, by applying scNanoSeq-CUT&Tag to testicular cells of adult mouse B6D2F1, we demonstrated that scNanoSeq-CUT&Tag maps dynamic epigenetic state changes during mouse spermatogenesis. Finally, we exploited the epigenetic changes of human leukemia cell line K562 during DNA demethylation, it showed that NanoSeq-CUT&Tag can capture H3K27ac signals changes along DNA demethylation. Overall, we prove that scNanoSeq-CUT&Tag is a valuable tool for efficiently probing chromatin state changes within individual cells.

Project description:This study aimed to adapt CUT&Tag to Plasmodium falciparum samples as an efficient and sensitive alternative to classical ChIP-sequencing. We compare H3K9me3 and HP1 CUT&Tag with ChIP-seq datasets, showing successful establishment of CUT&Tag in P. falciparum. Next we aimed to scale down required input material for our CUT&Tag reactions and generated high-quality HP1 tracks with as little as 10.000 nuclei. To minimise potential sample loss we tested feasibility of utilising (frozen) saponin parasite isolates as input material instead of nuclei, which proved to be viable. Lastly, we deployed our new technique Dimerisation-induced Biotinylation-CUT&Tag (DiBioCUT&Tag) to catch transient interactions by biotinylation of strongly associated proteins such as histones. We tested this technique on HP1 and compared standart CUT&Tag with DiBioCUT&Tag. Furthermore, we explored interactions of the transcription factor BDP5, which we were previously unable to succesfully ChIP.

Project description:To understand the mechanistic insights on how KDM1A inhibition sensitizes glioblastoma (GBM) to temozolomide, we performed genome wide localization studies of KDM1A in patient derived glioma stem cells (GSCs) using CUT&Tag-seq. GSC082209 (GSC08) cells were treated with vehicle or NCD38 (5 μM) for 24 h and 250,000 cells per condition were used. Data analysis on CUT&Tag sequencing reads was performed by the nf-core/cutandrun bioinformatic analysis pipeline. We detected 75,491 KDM1A peaks in the genome of GSCs (p<0.0001). Pathway analysis of KDM1A binding genes using Gene Ontology showed KDM1A binding genes were enriched in DNA repair, cell cycle, and UPR signaling pathways . CUT&Tag sequencing for KDM1A in patient derived glioma stem cells.

Project description:This study is aimed to Investigate whether C1qbp deficiency affects the histone modification during the differentiation stage of CD8+ T cells. Transferred WT and C1qbp KO P14 cells sorted from the spleen of donor mice on day 5 post-infection with LCMV Armstrong were collected and treated for CUT-tag. CUT-tag-Seq analysis provided evidence of histone modification changes between WT and C1qbp KO CD8+ T cells. Our study shows that on day 5 post-infection with LCMV Armstrong, along with mRNA expressing profiling, the CUT-tag-seq exhibits obvious changes in H3K27me3 and H3K27Ac modification of indicated genes of WT and C1qbp KO CD8+ T cells.

Project description:Cleavage Under Targets & Tagmentation (CUT&Tag) is an antibody-directed in situ chromatin profiling strategy that is rapidly replacing precipitation-based methods. The efficiency of the method enabled chromatin profiling in single cells but is limited by the numbers of cells that can be profiled. Here, we describe a combinatorial barcoding strategy for CUT&Tag that harnesses a nanowell dispenser for simple, high-resolution high-throughput single-cell chromatin profiling. We describe a pipeline for single-cell indexed CUT&Tag (sciCUT&Tag) that uses SNPs to facilitate doublet-cell removal and minimize batch effects. We illustrate the optimized protocol by analysis of mouse and human cell lines, as well as human peripheral blood mononuclear cells. We have also used sciCUT&Tag for simultaneous profiling of multiple chromatin epitopes in single cells. The reduced cost, improved resolution and scalability of sciCUT&Tag make it an attractive platform to profile chromatin features in single cells.

Project description:We recently introduced CUT&Tag, an epigenomic profiling strategy in which antibodies are bound to chromatin proteins in situ in permeabilized nuclei, and then used to tether the cut-and-paste transposase Tn5. Activation of the transposase simultaneously cleaves DNA and adds DNA sequencing adapters (“tagmentation”) for paired-end DNA sequencing. Here, we introduce a streamlined CUT&Tag protocol that suppresses exposure artifacts to ensure high-fidelity mapping of the antibody-targeted protein and improves signal-to-noise over current chromatin profiling methods. Streamlined CUT&Tag can be performed in a single PCR tube from cells to amplified libraries, providing low-cost high-resolution genome-wide chromatin maps. By simplifying library preparation, CUT&Tag requires less than a day at the bench from live cells to sequencing-ready barcoded libraries. Because of low background levels, barcoded and pooled CUT&Tag libraries can be sequenced for ~$25 per sample, enabling routine genome-wide profiling of chromatin proteins and modifications that requires no special skills or equipment.

Project description:Methods derived from CUT&RUN and CUT&Tag enable genome-wide mapping of the localization of proteins on chromatin from as few as one cell. These and other mapping approaches focus on one protein at a time, preventing direct measurements of co-localization of different chromatin proteins in the same cells and requiring prioritization of targets where samples are limiting. Here we describe multi-CUT&Tag, an adaptation of CUT&Tag that overcomes these hurdles by using antibody-specific barcodes to simultaneously map multiple proteins in the same cells. Highly specific multi-CUT&Tag maps of histone marks and RNA Polymerase II uncovered sites of co-localization in the same cells, active and repressed genes, and candidate cis-regulatory elements. Single-cell multi-CUT&Tag profiling facilitated identification of distinct cell types from a mixed population and inference of cell type-specific gene expression. In sum, multi-CUT&Tag increases the “per cell” information content of epigenomic maps, facilitating direct analysis of the interplay of different proteins on chromatin.
