Project description:This study profiled the transcriptome of zebrafish embryos harboring mutation in the Sin3A associated Protein 130b (sap130b) gene at 36 hours post fertilization (hpf). The sap130b mutant was generated via Cas9 mediated gene editing. Zebrafish sap130b mutants are viable and survive as adults with no observable phenotype. Maternal Zygotic sap130b mutants were established and they were also normal and it was reasoned that sap130a was compensating for the loss of sap130b. A transcriptome analysis was performed at 36 hpf to compare with our analysis of sap130a at this stage.
Project description:This study profiled the transcriptome of zebrafish embryos harboring mutation in the Sin3A associated Protein 130a (sap130a) gene at 36 hours post fertilization (hpf). The sap130a mutant was generated via Cas9 mediated gene editing. Zebrafish sap130a mutants are viable presumable due to the presence of maternal RNA. Generation of maternal zygotic (MZ) mutants resulted in an incomplete penetrance of heart ventricle defects that were visible as early as 36 hpf. In this experiment the MZsap130a mutant embryos were further sorted for embryos with smaller ventricle (SV) vs normal size ventricle (NV). To extend on this study and to specifically analyze the heart, sap130a mutant and WT hearts at 48 hpf were extracted for RNA-seq analysis.
Project description:In order to study Traf6 function during early zebrafish embryogenesis, transcriptome expression profiling was performed at 30% epiboly using a morpholino based knock-down approach.
Project description:In order to study Traf6 function during early zebrafish embryogenesis, transcriptome expression profiling was performed at 30% epiboly using a morpholino based knock-down approach. Two-factorial design with the factors 'Treatment' (5 levels:'Phenol Red', 'Standard Control', 'Mismatch', 'Morpholino1' and Morpholino 2') and 'Dose' (3 levels: 'Low', 'Middel' and 'High') with the factor 'Dose' only being applicable to the morpholino injections and not to the 'Phenol Red' control.
Project description:This SuperSeries is composed of the following subset Series: GSE32898: Comprehensive identification of long non-coding RNAs expressed during zebrafish embryogenesis [RNA_seq] GSE32899: Comprehensive identification of long non-coding RNAs expressed during zebrafish embryogenesis [ChIP_Seq] Refer to individual Series
Project description:We resolved the RNA secondary structure during zebrafish early embryogenesis based on in vivo click selective 2'-hydroxyl acylation and profiling experiment (icSHAPE). We analyzed the RNA structure dynamics among different development stages. Also, we studied which factors regulate maternal gene decay by RNA structure switch.
