(Submitter supplied) We used an in vitro cardiomyocyte differentiation system with inducible Hey1 or Hey2 expression to study target gene regulation in cardiomyocytes (CM) generated from murine embryonic stem cells (ESC). The effects of Hey1 and Hey2 are largely redundant, but cell type specific. The number of regulated genes is comparable between ESC and CM, but the total number of binding sites is much higher, especially in ESC, targeting mainly genes involved in transcriptional regulation and developmental processes. more...

(Submitter supplied) The differentiation to cardiomyocytes is a prerequisite and an important part of heart development. A good understanding of the complicated cardiomyocyte differentiation process benefits cardiogenesis study. Embryonic stem cells (ESCs), cell lines with infinite ability to proliferate and to be differentiated into all cell types of the adult body, are important research tools for investigation of differentiation and meanwhile good models for developmental research. more...

(Submitter supplied) We performed two independent siRNA mediated knockdowns of Srf (Srf si1 & Srf si2) and an unspecific siRNA (siNon) in mouse cardiomyocytes HL-1 cells. Small RNAs were sequenced by Illumina/Solexa next-generation (single-end) sequencing technology. The sequence reads were mapped to the mouse reference genome (NCBI v37, mm9) using MicroRazerS. MicroRazerS searches for the longest possible prefix-match of each read, i.e. more...

(Submitter supplied) We investigated the cardiac transcription network driven by the DNA-binding key factor Srf in combination with epigenetic marks of histone 3 acetylation (H3ac). Srf has been shown to play a key role in cardiac cell growth and muscle gene regulation. However, we still have limited understanding of the global transcription network driven by this factor in a direct or indirect manner. Moreover, we lack knowledge to which extent epigenetic marks such as histone modifications interfere with the regulation of direct targets. more...

(Submitter supplied) Differentiation of human pluripotent stem cells (hPSCs) can be used to model human heart development and, in turn, to analyze the developmental consequences of genetic abnormalities. Here, we deleted NKX2-5, a critical component of the cardiac gene regulatory network, in human embryonic stem cells (hESCs) and identified a novel genetic interaction between NKX2-5 and HEY2 that is required for heart development

(Submitter supplied) Primitive neural stem cells (NSCs) could be derived from pluripotent mouse embryonic stem (ES) cells, and then differentiate into definitive-type neural stem cells which resemble NSCs obtained from the central nervous system. Hence, primitive NSCs define an early stage of neural induction and provide a model to understand the mechanism that controls initial neural commitment. In this study, we performed microarray assay to analyze the global transcriptional profiles in mouse ES cell-derived primitive and definitive NSCs and to depict the molecular changes during the multi-staged neural differentiation process.

(Submitter supplied) Purpose: The goals of this study are to compare transcriptome profiling (RNA-seq) resulting from a Mesp1Cre driven ablation of Hira in the heart at E11.5 and E12.5. Methods: RNA extraction was done in triplicate from Mesp1Cre;Hira-/fl and Mesp1Cre;Hira+/fl embryonic hearts at E11.5 and E12.5 using the QIAGEN RNeasy mini kit. RNAseq was processed by the ICH genomics facility, reads were aligned and normalised using BOWTIE and DEseq R package. more...

(Submitter supplied) Notch signaling regulates a variety of developmental cell fates decisions in a cell-context dependent manner. Although Notch signaling directly regulates transcription via the RBP-J/CSL DNA binding protein, little is known about the genes in the respective tissues that are directly activated by Notch. To analyze how Notch signaling mediates its context dependent functions, we utilized a Tamoxifen(OHT)-inducible system (NERT) to activate Notch1 in embryonic stem cells (ESC) at different stages of mesodermal differentiation combined with global transcriptional analyses.

(Submitter supplied) The role of the histone mehyltrasferase G9a (also known as Ehmt2) in heart has not been extensively studied. To identify the genes regulated by G9a in the normal heart, we first generated a conditional, cardiac-specific KO mouse for this gene using the Cre-Lox approach, crossing G9a flox/flox mice with αMHC-MerCreMer mice (Cre mice were used as controls). Then, we sequenced total RNA (Total-RNA-seq) from cardiomyocyte-enriched populations isolated from G9a-KO and Cre mice, and compared the two expression profiles.

(Submitter supplied) The role of the histone methyltrasferase G9a (also known as Ehmt2) in the normal heart has not been studied extensively. To identify which genes were direct targets of G9a in hypertrophic cardiomyocytes, we performed ChIP-seq for G9a and H3K9me2 – the main histone methylation catalysed by the HMT – on cardiomyocytes isolated from normal mice (sham) and mice subject to transverse aortic constriction (TAC) for 1 wk, a surgical procedure that causes cardiac hypertrophy following the induction of pressure overload. more...

(Submitter supplied) The role of the histone methyltrasferase G9a (also known as Ehmt2) in the normal heart has not been studied extensively. To identify the genomic regions bound to G9a in cardiomyocytes (CMs),we first generated a conditional, cardiac-specific KO mouse for this gene using the Cre-Lox approach, crossing G9a flox/flox mice with αMHC-MerCreMer mice (Cre mice were used as controls). Then we performed ChIP-seq for G9a and H3K9me2 – the main histone methylation catalysed by the HMT – on isolated G9a-KO and Cre CMs, and considered the best G9a-bound genomic regions as those that had a loss or decrease of G9a binding as well as a lower level of H3K9me2 in G9a-KO CMs. more...

(Submitter supplied) Gene expression profiles of undifferentiated mouse embryonal carcinoma cell strains (P19, P19CL6, and 4 P19CL6 sublines) were obtained, using Affymetrix GeneChip Mouse Genome 430A and 430B. Heart diseases such as cardiac infarction damage cardiomyocytes and consequently lead to significant loss of the contractile capacity of the heart. To repair functions of the injured heart, a great deal of research has attempted to develop regenerative medicine using pluripotent stem cell-based cardiomyocytes as cell therapy products. more...

(Submitter supplied) Progenitor cells of the first and second heart fields (FHF and SHF) depend on cardiac-specific transcription factors for their differentiation. In mouse mutant embryos, we define the hierarchy of signaling events that controls the expression of cardiac-specific transcription factors during commitment of SHF progenitors at E9.25. Wnt and Bmp act downstream of Notch/RBPJ at this developmental stage. Mutation of Axin2, the negative regulator of canonical Wnt signaling, enhances Wnt and Bmp signals and suffices to rescue the cardiac differentiation arrest caused by loss of RBPJ. more...
