Project description:hnRNP M and Rbfox proteins are subunits of the Large Assembly of Splicing Regulators (LASR). The purpose of this study is to investigate how these two splicing factors affect each others' role in regulating splice site choices in pre-mRNA. hnRNP M is knocked down by RNAi in Flp-In T-REx 293 cells (Invitrogen), whereas Rbfox1 is expressed inducibly under tetracycline control from construct integrated into the genome at the FRT site. Using this system, splicing and expression profiles of cells expressing and/or lacking these proteins are compared on a whole genome level by RNA-seq technology.

Project description:Alternative splicing (AS) is an important component of RNA processing controlled by cis- and trans-acting component. Here we investigate modes and mechanisms of AS co-regulation by MBNL1 and RBFOX1. We generated two cell models (human and mouse) whereby the expression of both RBPs can be independently modulated and utilize these cell lines to perform RNAseq and transcriptome wide alternative splicing analysis. Categorization of alternative splicing outcomes of the impacts of RBFOX1 expression on MBNL1 splicing revealed a common co-regulatory mode whereby RBFOX1 buffers MBNL1 dose-dependent splicing regulation by reducing the total range of exon inclusion induced. Overall, our studies define a conserved co-regulatory mechanism through which RBFOX1 and MBNL1 can fine-tune and provide redundancy for AS outcomes.

Project description:We used RNA sequencing to identify the RBFOX1 splicing network at a genome-wide level in primary human neural stem cells during differentiation. We observe that RBFOX1 regulates a large set of alternative splicing events implicated in neurogenesis and cell maintenance. Subsequent alterations in gene expression define an additional transcriptional network regulated by RBFOX1 involved in neurodevelopmental pathways remarkably parallel to those affected by splicing. RNA sequencing at a 75bp single-end read scale was performed using polyA-enriched RNA from 5 biological replicates of primary human neural progenitor cell lines generated by lentiviral-mediated knockdown of GFP (control) or RBFOX1 and differentiated for 4 weeks.

Project description:Understanding how RNA binding proteins control the splicing code is fundamental to human biology and disease. Here we present a comprehensive study to elucidate how heterogeneous nuclear ribonucleoparticle (hnRNP) proteins, among the most abundant RNA binding proteins, coordinate to regulate alternative pre-mRNA splicing (AS) in human cells. Using splicing-sensitive microarrays, cross-linking and immunoprecipitation coupled with high-throughput sequencing, and cDNA sequencing, we find that more than half of all AS events are regulated by multiple hnRNP proteins, and that some combinations of hnRNP proteins exhibit significant synergy, whereas others act antagonistically. Our analyses reveal position-dependent RNA splicing maps, in vivo consensus binding sites, a surprising level of cross- and auto-regulation among hnRNP proteins, and the coordinated regulation by hnRNP proteins of dozens of other RNA binding proteins and genes associated with cancer. Our findings define an unprecedented degree of complexity and compensatory relationships among hnRNP proteins and their splicing targets that likely confer robustness to cells. In triplicate, polyA-selected RNA was extracted from control, hnRNP A1, hnRNP A2/B1, hnRNP H1, hnRNP F, hnRNP M, and hnRNP U siRNA treated human 293T cells, and hybridized to custom splice-junction arrays

Project description:Rbfox1 regulates the alternative splicing of many transcripts in neurons. We have characterized the Rbfox1-dependent changes in expression and alternative splicing by comparing Rbfox1-KO brain to WT brain. In this dataset, we include the splicing and expression data obtained from dissected WT and Rbfox1 KO mouse brains. 6 total samples were analyzed: brains from 3 WT male mice and 3 Rbfox1 KO male mice, all 1 month of age.
