Genome-wide maps of chromatin state in wild type and E2A knockout neural progenitor cells

ABSTRACT: Background: E2A, encoded by the TCF3 gene locus, belongs to the E protein transcription factor family, which also includes HEB (TCF12) and E2-2 (TCF4), has been suggested to play an important role in leukemogenesis. However, far less is known about the function of E2A in cell-fate regulation of hESCs. Therefore, further understanding of E2A in self-renewal and differentiation of embryonic stem cells may be influenced. In the study, we demonstrated E2A knockout exhibited blocked neural differentiation, which is tightly related to histone modification H3K4me3 and H3K27me3. Methods: The genomic DNA of H3K4me3 and H3K27me3 binding peaks in wild type and E2A knockout neural progenitor cells were generated by ChIP-seq technique using IIIumina Hiseq 2500. Results: A comprehensive human chromatin state of H3K4me3 and H3K27me3 in wild type and E2A knockout neural progenitor cells was provided. Function enrichment, network characteristics and disease association of the binding peaks were analyzed. Conclusion: The dataset could serve as a baseline resource for investigating the potential effects and mechanism of H3K4me3/H3K27me3/E2A complex in neural differentiation period of embryonic stem cells

Genome-wide maps of E2A binding peaks in Embryonic stem cells and Neural progenitor cells

Project description:Background: E2A, encoded by the TCF3 gene locus, belongs to the E protein transcription factor family, which also includes HEB (TCF12) and E2-2 (TCF4), has been suggested to play an important role in leukemogenesis. However, far less is known about the function of E2A in cell-fate regulation of hESCs. Therefore, further understanding of E2A in self-renewal and differentiation of embryonic stem cells may be influenced. Methods: The mRNA profiles of wildtype and E2A knockout embryonic stem cells were generated by RNA-seq technique, in triplicate for each group, using IIIumina Hiseq 2500. Results: A comprehensive human transcriptome map of wild type and E2A knockout embryonic stem cells was provided. Function enrichment, network characteristics and disease association of the differentially expressed genes were analyzed. Conclusion: The dataset could serve as a baseline resource for investigating the potential effects and mechanism of E2A in embryonic stem cells.

Genes regulated by HEB and E2A during DP stage of thymocyte development

Project description:To investigate gene targets of the E-proteins HEB and E2A during the CD4+CD8+ double positive (DP) stage of T cell development. We examined E-protein function by simultaneous removal of both HEB (Tcf12) and E2A (Tcfe2a) genes at the DP stage. This was done by crossing mice containing HEB floxed and E2A floxed alleles to a CD4Cre background (Tcf12f/fTcfe2af/fCD4Cre mice). Microarray analysis was used to compare gene expression in HEB and E2A double deficient DP thymocytes (Cre+) to Cre- control DP thymocytes. Keywords: genetic modification

ChIP-Seq of TAL1 and its regulatory partners in T-ALL cells

Project description:The oncogenic transcription factor TAL1/SCL is aberrantly expressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing its importance in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regulatory circuit controlled by TAL1 and its regulatory partners HEB, E2A, LMO1, LMO2, GATA3 and RUNX1 in T-ALL cells. We show that TAL1 forms an interconnected auto-regulatory loop with its partners, and that the TAL1 complex directly activates the MYB oncogene, forming a feed-forward positive regulatory loop that further promotes the TAL1-regulated oncogenic program. one of the cirtical downstream targets in this circuitry is the TRIB2 gene, which is oppositely regulated by TAL1 and HEB/E2A, and is essential for the survival of T-ALL cells. Human T-ALL cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total TAL1 (Santa Cruz SC-12984), TCF12/HEB (Santa Cruz SC-357),TCF3/E2A (Santa Cruz SC-349X), LMO1 (Santa Cruz SC-10494), LMO2 (R&D AF2726),GATA3 (Santa Cruz SC-22206) and RUNX1 (Santa Cruz SC-8563). This represents the ChIP-seq portion of this dataset.

Core transcriptional regulatory circuit controlled by the tal1 complex in human t-cell acute lymphoblastic leukemia (Subseries)

Project description:The oncogenic transcription factor TAL1/SCL is aberrantly overexpressed in over 40% of cases of T-cell acute lymphoblastic leukemia (T-ALL), emphasizing the importance of the TAL1-regulated transcriptional program in the molecular pathogenesis of T-ALL. Here we identify the core transcriptional regulatory circuit controlled by TAL1 and its regulatory partners HEB, E2A, GATA3, ETS1 and RUNX1 in T-ALL cells. We find that TAL1 forms an interconnected auto-regulatory loop with its partners, which contributes to the sustained upregulation of its direct target genes. Importantly, we also find the MYB oncogenic transcription factor is directly activated by the TAL1 complex and positively regulates many of the same target genes, thus forming a feed-forward positive regulatory loop that further promotes the TAL1-regulated oncogenic program. Human T-ALL cells were cross-linked with formaldehyde for 20 min. DNA was enriched by chromatin immunoprecipitation (ChIP) and analyzed by Solexa sequencing. A sample of whole cell extract (WCE) was sequenced and used as the background to determine enrichment. ChIP was performed using an antibody against total TAL1 (Santa Cruz SC-12984), TCF12/HEB (Santa Cruz SC-357),TCF3/E2A (Santa Cruz SC-349X), LMO1 (Santa Cruz SC-10494), LMO2 (R&D Systems AF2726), GATA3 (Santa Cruz SC-22206) and RUNX1 (Santa Cruz SC-8563). This represents the ChIP-seq portion of this dataset. Human Jurkat cells were cross-linked with formaldehyde for 20 min.

HEB and E2A function as SMAD/FOXH1 cofactors

Project description:Nodal signaling, mediated through SMAD transcription factors, is necessary for pluripotency maintenance and endoderm commitment. We have identified a new motif, termed SMAD Complex Associated (SCA) that is bound by SMAD2/3/4 and FOXH1 in human embryonic stem cells (hESCs) and derived endoderm. We demonstrate that two bHLH proteins - HEB and E2A - bind the SCA motif at regions overlapping SMAD2/3 and FOXH1. Further, we show that HEB and E2A associate with SMAD2/3 and FOXH1, suggesting they form a complex at critical target regions. This association is biologically important, as E2A is critical for mesendoderm specification, gastrulation, and Nodal signal transduction in Xenopus tropicalis embryos. Taken together, E2A is a novel Nodal signaling cofactor that associates with SMAD2/3 and FOXH1 and is necessary for mesendoderm differentiation. ChIP-seq of Smad2/3 and Input in X.tropicalis, stage 10.5 embryo.
