(Submitter supplied) The Gata4 transcription factor is essential for normal heart development, but the molecular basis for its function remain poorly understood. We profiled at the whole genome level transcript changes in cardiomyocytes when Gata4 is depleted from zebrafish embryos. Our objective was to elucidate the cardiomyocyte-specific molecular program functioning downstream of Gata4 in order to better understand the role of Gata4 in cardiac morphogenesis.

Analysis of RUES2 stem cells first depleted for transmembrane protein 88 (TMEM88) and then induced to differentiate into cardiac cells. RUES cells examined at day 5 of differentitation. Results provide insight into the role of TMEM 88 in cardiac cell differentiation.

(Submitter supplied) Acetylcholinesterase (AChE) inhibitors are widely used as pesticides and drugs. Their primary effect is the overstimulation of muscular activity. Whether AChE inhibitors and related neurotoxic compound also provoke specific changes in gene transcription patterns that allow to establish a mechanistic link useful for diagnostic purposes has, however, yet not been investigated. Therefore, as a proof of principle, we examined the transcriptomic response of a known AChE inhibitor, the organophosphate azinphos-methyl (APM), in zebrafish embryos and compared the response with two non-AChE inhibiting control compounds, 1,4-dimethoxybenzene (DMB) and 2,4-dinitrophenol (DNP). more...

(Submitter supplied) To identify genes regulated by Rx3 during optic vesicle morphogenesis, adult zebrafish carriers of a null rx3 mutation were mated. Before 13 hours post fertilization (hpf), the earliest time point at which optic vesicle evagination phenotypes could be reliably detected, offspring were phenotypically separated into pools comprising of mutants with an absence of optic vesicles or siblings exhibiting a wild-type phenotype. more...

(Submitter supplied) Gata5 efficiently promotes cardiomyocyte fate from murine ESCs.By removing serum from the culture conditions, GATA4 and GATA6 are each also able to efficiently promote cardiogenesis in ESC derivatives, with some distinctions. Thus, GATA factors can function in ESC derivatives upstream of other cardiac transcription factors to direct specification of progenitors with cardiac potential. We used microarray to compared the global gene expression of Gata5-induced cardiac cells with other growth factor directed ESC-derived cardiac cells

(Submitter supplied) Purpose: To compare NGS-derived transcriptome profiling (RNA-seq) between Wild Type and Ptprz1-/- LMVEC and identify transcripts that may be linked to the phenotypic differences observed. Methods: Total RNA from freshly cultured LMVEC was extracted using the NucleoSpin RNA Plus kit from Macherey-Nagel and the concentration and purity was assessed by Nanodrop and gel agarose 1% in TBE 0.5x. RNA from 3 independent fresh cell isolations from the Ptprz1+/+ and the Ptprz1-/- LMVEC was extracted and sent for RNAseq analysis. more...

(Submitter supplied) By using transgenic zebrafish lines Tg(nxk2.5:GFP) (Witzel et al. 2012) and Tg(myl7:EGFP) (D'Amico et al. 2007), we have characterized chromatin accessibility of FACS-isolated CM (GFP+) from developing zebrafish heart at 24, 48 and 72 hpf, corresponding to heart tube formation, chamber formation and differentiation and heart maturation, respectively. GFP- cells were used as a control. We have identified cardiac regulatory networks playing a crucial role in heart morphogenesis. more...

(Submitter supplied) GATA4 regulates the liver development, but it's function and the gene transcriptional programs it regulates in the adult liver is unknown. In this study, we determined the genome-wide occupancy sites of GATA4 by performing ChIP-seq of whole livers. We have identified 4409 GATA4 enrichment peaks using two peak calling methods and irreproducible discovery rate (IDR) analysis. This corresponds to 3075 genes with GATA4 peaks within -5 kb of transcription start site (TSS) and +5 kb of transcription termination site (TTS). more...
