CUT&RUN LoV-U of beta-catenin, TCF/LEF transcription factors and histone modifications in HEK293T and mouse embryonic hindlimb tissue at 11.5 days post coitum

Project description:In our attempts to profile different regulators of the WNT/b-catenin transcriptional complex, CUT&RUN failed to produce consistent binding patterns of the non-DNA-binding b-catenin. We developed a modified CUT&RUN protocol, which we refer to as LoV-U (Low Volume and Urea), that enables the generation of robust and reproducible b-catenin binding profiles. CUT&RUN-LoV-U can profile all classes of chromatin regulators tested, as shown by datasets targeting the TCF/LEF transcription factors and various histone modifications. CUT&RUN-LoV-U uncovers direct WNT/β-catenin target genes in human cells, as well as in ex vivo cells isolated from developing mouse tissue.

CUT&RUN Negative Controls in Human and Mouse

Project description:We performed 8 C&R tests in HEK293T human cells and 8 in mouse embryonic tissues from JAX Swiss mice by using either IgG or anti-HA antibodies. To increase diversity in this test, we used both the original C&R protocol and our recently developed C&R-LoV-U version for non-DNA-binding transcriptional co-factors. The aim was to experimentally validate our generated CUT&RUN blacklists containing problematic high signal regions.

CUT&RUN experiment in colon cancer cells (HCT116, DLD1 and SW620), assessing TBX3 genomic occupancy

Project description:The Wnt/β-catenin signaling pathway plays crucial roles in nearly all parts of embryonic development and adult stem cell homeostasis. Its aberrant activation has been linked to many diseases such as developmental irregularities and various severe forms of cancer, with colorectal cancer (CRC) as a prime example. While much work has been dedicated to uncovering effective therapeutics to block oncogenic Wnt signaling, such interventions have not proven trivial because of the broad activity of Wnt throughout the adult body and the difficulty in finding suitable molecular targets. We have previously identified the developmental transcription factor TBX3 as a participant of the Wnt-mediated transcriptional regulation. Here we examine the genome-wide binding pattern of TBX3 in the human CRC cells lines HCT116 (25 replicates), DLD1 (2 replicates) and SW620 (2 replicates), by employing CUT&RUN (C&R) with Low-Volume and Urea (LoV-U; Zambanini et al., 2022).

CUT&RUN of histone modifications, chromatin remodelers, and transcription factors in forelimbs, hindlimbs, liver and branchial arches of E10.5 and E11.5 JAX/Swiss mouse embryos

Project description:Using CUT&RUN, we systematically measured the genome-wide binding profiles of key transcription factors and cofactors that track the activity of ontogenetically relevant signaling pathways in developing mouse tissues. This produced numerous genome-wide biding tracks for different tissues at two developmental stages in biological duplicate. Submitted files include raw fastq files, bigwig files from merged biological replicates, and peak sets.

CUT&RUN experiment at four time points in HEK293T and hESC cells, assessing the time-resolved response of β-catenin genomic occupancy upon Wnt signaling activation

Project description:Wnt/β-catenin signaling is a highly organized biochemical cascade that triggers a gene expression program in the signal-receiving cell. The Wnt/β-catenin-driven transcriptional response is involved in virtually all cellular processes during development, homeostasis, and its deregulation causes human disease. However, outstanding questions remain unanswered. A first question concerns cell-specificity: how this response is integrated into lineage-specific choices is still unknown. A second question concerns time: it is not known whether β-catenin associates with its targets simultaneously or in a time-dependent fashion. For instance, while TCF/LEF and other components of the Wnt transcriptional complex are constitutively associated with the chromatin, it is β-catenin arrival, upon Wnt induction, that launches target genes transcription. Therefore, discovering the dynamics of the genome-wide β-catenin binding pattern is required to unambiguously define the direct targets of Wnt signaling To address these questions, we realized a time-resolved atlas of β-catenin genome-wide occupancy in two human cell types, human embryonic kidney cells 293T (HEK293T) and human embryonic stem cells (hESCs). To this end, we treated HEK293T and hESCs with the GSK3 inhibitor/Wnt activator CHIR99021 (10 mM) for 3 days, and assessed β-catenin binding via CUT&RUN-LoV-U (Zambanini et al., 2022) 90 minutes, 4 hours, 24 hours and 3 days after the onset of the stimulation. This approach allowed us to establish that β-catenin repositions to different genomic loci along stimulation time, showing that a definition of Wnt target genes must take into account the time-dimension. Moreover, β-catenin physical targets are largely cell-type specific, as only a subset of them is present across the examined contexts.

Epigenetic regulation of reactivation of the silenced X-chromosome during mouse germline development

Project description:X chromosome reactivation (XCR) occurs over a prolonged period during genome-wide reprogramming in female germ cells, initiating soon after primordial germ cell specification. The kinetics of XCRs remain poorly understood, as previous studies of XCR were based on a few genes. For a global appraisal of the regulation of XCR dynamics, we performed matched CUT&RUN for H3K27me3 and H2AK119ub1 on F1 female (XX(Xist∆)) germ cells at E13.5 and E16.5 stages during embryonic development.

HyPro-seq analysis of HeLa and ARPE-19 cells

Project description:The ability of RNAs to form specific contacts with other macromolecules provides an important mechanism for subcellular compartmentalization. We developed a suite of hybridization-proximity (HyPro) labeling technologies for unbiased discovery of proteins (HyPro-MS) and transcripts (HyPro-seq) associated with RNAs of interest in genetically unperturbed cells. To generate the HyPro-seq dataset reported here, fixed and permeabilized human cells were hybridized with digoxigenin-labeled oligonucleotide probes against noncoding RNAs 45S, NEAT1 or PNCTR and transcripts co-localizing with these RNAs were biotinylated in situ using a custom-engineered HyPro enzyme containing a digoxigenin-binding domain. Biotinylated RNAs were then purified and sequenced using the NextSeq 500 Illumina platform.
