RNA_Seq analysis of localization along animal-vegetal axis of Acipenser ruthenus

We performed cryosectioning of oocytes along the animal-vegetal axis (first developmental axis, section A (first animal) to section E (last vegetal), followed by RNA-Seq to determine the localization profiles of coding and noncoding RNAs. The method allowed for a complete view on RNA localization. We found that nearly all RNAs are localized, but only a small percentage is actively transported during oogenesis. RNA profiles (mRNA, lncRNA, other RNA) were generated by deep sequencing, in biological triplicates (each oocyte divided into five segments), using Illumina HiSeq.
