Trancriptome study of zebrafish mutant fn10a

ABSTRACT: We conducted functional analysis on zebrafish mutant fn10a by polyA+, 100bp paired end, strand-specific RNA-seq. By comparing the transcriptome of fn10a mutants and their wildtype siblings or wildtype controls, we revealed a transcriptome-wide RNA splicing deficiency and a large amount of intron-retaining transcripts, which resulted in compromised nonsense-mediated RNA decay and activation of the p53 pathway in fn10a mutants. 2 biological replicates were performed to consolidate the findings. We also conducted subcellular RNA-seq between fn10a mutants and wildtype siblings, to investigate the localization of intron retaining transcripts. Overall design: The wild-type control group (WT-control group) of 36-hpf embryos was generated from mating crosses between wild-type TL zebrafish, while fn10a mutants (mutant group) and siblings (WT-sibling group) were generated from mating crosses of fn10a heterozygote zebrafish. RNA-seq of 36hpf embryos for fn10a mutants, their wildtype siblings and wildtype TL. RNA-seq of cytoplasm RNA and nuclear RNA from 36hpf embryos for fn10a mutants and their wildtype siblings.

Haploinsufficiency of EFTUD2 (Elongation Factor Tu GTP Binding Domain Containing 2) is linked to human mandibulofacial dysostosis, Guion-Almeida type (MFDGA), but the underlying cellular and molecular mechanisms remain to be addressed. We report here the isolation, cloning and functional analysis of the mutated eftud2 (snu114) in a novel neuronal mutant fn10a in zebrafish. This mutant displayed abnormal brain development with evident neuronal apoptosis while the development of other organs appea  ...[more]
