Project description:We sequenced RNA from adult mouse spinal cord and from cell sorted Nova2-cKO neurons (crossed with Emx1-Cre, Gad2-Cre, Pcp2-Cre driver mice) and from Nova2.Ptbp2-dKO to compare gene expression level, and alternative splicing events.

Project description:To assess the requirement of Nova2 for alternative processing of RNA in mouse brain. Protein-RNA interactions play critical roles in all aspects of gene expression. Here we develop a genome-wide means of mapping protein-RNA binding sites in vivo, by high throughput sequencing of RNA isolated by crosslinking immunoprecipitation (HITS-CLIP). HITS-CLIP analysis of the neuron-specific splicing factor Nova2 revealed extremely reproducible RNA binding maps in multiple mouse brains. These maps provide genome-wide in vivo biochemical footprints confirming the previous prediction that the position of Nova binding determines the outcome of alternative splicing; moreover, they are sufficiently powerful to predict Nova action de novo. HITS-CLIP revealed a large number of Nova-RNA interactions in 3â UTRs, leading to the discovery that Nova regulates alternative polyadenylation in the brain. HITS-CLIP, therefore, provides a robust, unbiased means to identify functional protein-RNA interactions in vivo. Keywords: Comparative analysis Refer to individual Series.

Project description:To assess the requirement of Nova2 for alternative processing of RNA in the developping brain. Neuronal migration leads to a highly organized laminar structure in the mammalian brain and its mis-regulation causes lissencephaly, behavioral and cognitive defects. Reelin signaling, mediated in part by a key adaptor, disabled-1 (Dab1), plays a critical but incompletely understood role in this process. We found that the neuron-specific RNA binding protein Nova2 regulates neuronal migration in late-generated cortical and Purkinje neurons. An unbiased HITS-CLIP and exon junction array search for Nova-dependent RNAs at E14.5 focused on components of the reelin pathway revealed only one candidate—an alternatively spliced isoform of Dab1 (Dab1.7bc). In utero electroporation demonstrated that Dab1.7bc was sufficient to induce neuronal migration defects in wild-type mice and exacerbate defects when Dab1 levels were reduced, while Dab1 overexpression mitigates defects in Nova2-null mice. Thus Nova2 regulates an RNA switch controlling the ability of Dab1 to mediate neuronal responsiveness to reelin signaling and neuronal migration, suggesting new links between splicing regulation, brain disease and development.

Project description:Angiogenesis is crucial for cancer progression and anti-angiogenic drugs are in use for its treatment. However, their clinical benefits are unsatisfactory. Thus, a deeper understanding of the mechanisms sustaining cancer vessel growth is crucial to identify better biomarkers and novel therapeutic targets. Alternative Splicing (AS) is an essential modifier of human proteome diversity. Nevertheless, its contribution to tumor vasculature development is poorly known. NOVA2 is an important AS regulator of angiogenesis and vascular development and it is up-regulated in tumor endothelial cells (ECs) of different cancers, thus representing a potential driver of tumor blood vessels aberrancies. Here, we identified novel AS transcripts generated upon NOVA2 upregulation in ECs, suggesting a pervasive role of NOVA2 in vascular biology. In addition, we report that NOVA2 is also upregulated in ECs of gastric cancer (GC), with its expression correlating with poor overall survival of the GC patients. We also found that the AS of the newly identified NOVA2 target RapGEF6 is altered in GC patients and associated with NOVA2 expression, tumor angiogenesis and poor patient outcome. Our findings provide a better understanding of GC biology and suggest that AS might represent a potential source of biomarkers and therapeutics for novel anti-angiogenic GC treatments.
