Title Zebrafish 24hpf mutant sk8 gene expression
Organism Danio rerio
Experiment type Expression profiling by array
Summary The production of functional mRNA involves multiple steps including transcription initiation, elongation, and termination. spt5 encodes a conserved essential transcription elongation factor that controls RNAPII processivity in vitro and co-localizes with RNAPII in vivo.
We used microarrays to detail the global expression of gene expression at 24 hours post fertilization in wild-type and Spt5 mutant (fog-sk8) to identify Spt5 transcriptionally dependent genes and affected pathways. Here we report that a mutation in zebrafish spt5, sk8, deregulates <5% of ~10,000 genes examined. These findings reveal a small but diverse set of developmentally regulated genes, whose expression is critically dependent on Spt5-regulated RNAPII stalling in vertebrate development.

Keywords: comparison
Overall design RNA from zebrafish embryos were harvested at 24 hours post fertilization for hybridization to Affymetrix gene arrays.
