Expression data from WT, HEB-KO and E2A-KO LY6D- CLP cells

ABSTRACT: The E-protein transcription factors E2A and HEB play important roles at several stages of hematopoiesis. However, the exact mechanism for theire action and the main targets in the LY6D negative common lymphoid progentior (CLP) compartment remains unknown. By adressing this question, we will gain important infromation regarding the early events leading to B-cell specification. FACS sorted LY6D negative common lymphoid progenitors from WT, HEB-KO and E2A-KO mice were subjected to RNA extraction and hybridization on Affymetrix microarrays. At least two independent sorts were performed per genotype. During each sort, cells were pooled from several bone marrows.

The transcription factors E2A and HEB act in concert to induce the expression of FOXO1 in the common lymphoid progenitor.

Recent studies have identified a number of transcriptional regulators, including E proteins, EBF1, FOXO1, and PAX5, that act together to orchestrate the B-cell fate. However, it still remains unclear as to how they are linked at the earliest stages of B-cell development. Here, we show that lymphocyte development in HEB-ablated mice exhibits a partial developmental arrest, whereas B-cell development in E2A(+/-)HEB(-/-) mice is completely blocked at the LY6D(-) common lymphoid progenitor stage. We ...[more]

Transcription profiling of mouse WT and E2A-KO bone marrow stem and progenitor cell subfractions.

Project description:Expression profiling of WT and E2A-KO LSK FLT3- and LMPP protenitor cells. Experiment Overall Design: LSK FLT3- and LMPP stem/progenitor cells from WT and E2A-KO mice were FACS sorted. Subsequently RNA was extracted, labelled and hybridized to Affymetrix microarrays. Goal of experiment was to investigate expression changes between WT and KO LMPP 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

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.

Innate versus adaptive lymphoid cell fate choice is controlled by the E-Id protein axis [ATAC-Seq]

Project description:The lymphoid branch of the immune defense is composed of innate and adaptive immune cells. Using multiple genetic strategies we demonstrate that in the thymus E2A and HEB act in synergy to establish T cell identity and to suppress the aberrant development of innate lymphoid cells that include ILC2 and LTi-like cells. We found that E2A and HEB induce T cell fate by activating the expression of an ensemble of genes encoding for proteins associated with Notch- and pre-TCR signaling and to promote TCRβ antigen receptor assembly. We show that E2A and HEB act in early T progenitors (ETPs) to establish and maintain a T-lineage specific enhancer repertoire, including regulatory elements associated with the Notch1/3 and Rag1/2 gene loci. Based on these and previous observations we propose that the E-Id protein axis specifies innate versus adaptive lymphoid cell fate.

Transcriptome profiling of wildtype and E2A knockout embryonic stem 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.
