Project description:Long non-coding RNAs (lncRNAs) have emerged as critical regulators of gene expression and chromatin modifications, with important functions in development and disease. Here we sought to identify and functionally characterize lncRNAs critical for vascular vertebrate development with significant conservation across species. Genome-wide transcriptomic analyses during human vascular lineage specification enabled the identification of three conserved novel lncRNAs: TERMINATOR, ALIEN and PUNISHER that are specifically expressed in pluripotent stem cells, mesoderm and endothelial cells, respectively. Gene expression profiling, alongside RNA immunoprecipitation coupled to mass spectrometry, revealed a wide range of new molecular networks and protein interactors related to post-transcriptional modifications for all three lncRNAs. Functional experiments in zebrafish and murine embryos, as well as differentiating human cells, confirmed a developmental-stage specific role for each lncRNA during vertebrate development. The identification and functional characterization of these three novel non-coding provide a comprehensive transcriptomic roadmap and shed new light on the molecular mechanisms underlying human vascular development. shRNA knock down of lncRNAs followed by microarray gene expression profiling

Project description:During early vertebrate development, a large number of noncoding RNAs are maternally inherited or expressed upon activation of zygotic transcription. The exact identity, expression levels, and function during early vertebrate development for most of these noncoding RNAs remains largely unknown. miRNAs (microRNAs) and piRNAs (piwi-interacting RNAs) are two classes of small non-coding RNAs that play important roles in gene regulation during early embryonic development. Here, we utilized Illumina next generation sequencing technology to determine temporal expression patterns for both miRNAs and piRNAs during four distinct stages of early vertebrate development using zebrafish as a model system. For miRNAs, the expression patterns for 192 known miRNAs and 12 novel miRNAs within 123 different miRNA families were determined. Significant sequence variation was observed at the 5' and 3' ends of miRNAs with a large number of extra nucleotides added in a non-template directed manner. We also identified a large and diverse set of piRNAs expressed during early development, far beyond that expected if piRNA expression is restricted to germ cells. Our analyses represent the deepest investigation to date of small RNA expression during early vertebrate development and suggest important novel functions for small RNAs during embryogenesis.
