Invasion, metastasis and therapy resistance are the major cause of cancer-associated deaths, and the EMT-inducing transcription factor ZEB1 is a crucial stimulator of these processes. While work on ZEB1 has mainly focused on its role as a transcriptional repressor, it can also act as a transcriptional activator. To further understand these two modes of action, we performed a genome-wide ZEB1 binding study in triple-negative breast cancer cells. We identified ZEB1 as a novel interactor of the AP- ...[more]

The Genomic Binding Profile of GAGA Element Associated Factor (GAF) in Drosophila S2 cells

Project description:GAGA associated transcription factor (GAF) is a highly abundant and essential protein in Drosophila. GAF recognizes and binds arrays of GA dinucleotides via a zinc finger DNA binding domain to regulate transcription by binding to general TF machinery or recruit nucleosome remodeling factors. We performed GAF ChIP-seq to quantify the intensity of GAF binding at high resolution in S2 cells. In addition, we performed GAF ChIP-seq in S2 cells that were depleted of GAF by RNAi. By quantifying the degree to which all GAF binding sites are susceptible to GAF depletion, we found the cellular degree of depletion does not translate equally to the depletion of GAF at individual chromatin bound sites. For example, some high intensity GAF binding sites were completely unaffected by GAF depletion, while lower affinity binding sites were often ablated upon GAF depletion. These data sets will serve as a valuable resource to others who study the dynamic interplay between GAF and chromatin. We also compared the GAF binding sites to the full set of genomic ChIP data that is available for S2 cells and compared the intensity for each factor and histone modification/variant. Lastly, we investigated the influence that GAF had upon inducible transcription factor binding using the heat shock system. A single mock immunoprecipitation (IP) using non-specific IgG was used as a background dataset for this study (see PMID: 20844575; GSM470838). We performed two independent GAF-ChIP-seq experiments in untreated S2 cells and two replicates in S2 cells that were depleted of GAF by RNAi.

Mouse ES cells expressing catalytically inactive Ring1B display impaired Ring1B and H3K27me3 deposition.

Project description:ChIP-seq for H3K27me3 and Ring1B was performed in WT mESCs and mESCs containing catalytically inactive Ring1B (I53A mutant). Cells expressing catalytically inactive Ring1B maintain the spatial distribution of Ring1B and H3K27me3 but at reduced levels. These findings support the notion that PRC2 recruitment is, in part, dependent on H2A ubiquitination (H2AK119ub). Two biological replicates were performed for Ring1B and H3K27me3 ChIPs in WT and Ring1B I53A/I53A mouse ESCs. Input chromatin was sequenced for each replicate as a control for ChIP enrichment.

Nucleoporin Nup153 Regulates Stem Cell Pluripotency through Gene Silencing

Project description:Nucleoporins (Nups) are a family of proteins best known as the constituent building blocks of nuclear pore complexes (NPCs), the transport channels that mediate nuclear transport. Recent evidence suggest that several Nups have additional roles in controlling the activation and silencing of developmental genes, however, the mechanistic details of these functions remain poorly understood. Here, we show that depletion of Nup153 in mouse embryonic stem cells (mESCs) causes the de-repression of developmental genes and induction of early differentiation. This loss of pluripotency is not associated with defects in global nucleo-cytoplasmic transport activity. Instead, Nup153 binds to the transcriptional start site (TSS) of developmental genes and mediates the recruitment of the polycomb repressive complex 1 (PRC1) to its target loci. Our results reveal a nuclear transport-independent role of Nup153 in maintaining stem cell pluripotency and introduce a role of NPC proteins in mammalian epigenetic gene silencing.

Chromatin accessibility (ATAC-seq) of human acute leukemias and healthy donors

Project description:ATAC-seq of 79 primary samples obtained from human acute leukemias, namely AML, T-ALL and mixed myeloid/lymphoid leukemias with CpG Island Methylator Phenotype (CIMP). Moreover, ATAC-seq of CD34+ HSPCs from 3 healthy donors are included. ATAC-seq was performed as described (Buenrostro et al., 2013) with a modification in the lysis buffer to reduce mitochondrial DNA contamination. Due to patient confidentiality considerations, the raw data files for this dataset have been deposited to the EGA controlled-access archive under the accession numbers EGAS00001007094 (study); EGAD00001011050 (dataset).

Dynamics of H3K4me2 during cardiac lineage reprogramming

Project description:During reprogramming of fibroblasts into cardiomyocyte-like cells by overexpression of transcription factors, GATA4, Hand2, Mef2C and Tbx5 (GHMT), H3K4Me2, an active histone code, shifts from fibroblast-exclusive peaks to cardiomyocyte-exclusive peaks. Important cardiac genes are gradually marked by this active histone marker. Mouse embryonic fibroblasts (MEFs) and neonatal mouse ventricular cardiomyocytes (NMVMs) represent fibroblasts and cardiomyocytes, respectively. Chromatins harvested from MEFs infected with retroviruses carrying GHMT at day 3, day 5, day 7 post-viral infection were prepared for immunoprecipitation.
