RNAseq of livers from WT mice or livers with Rbfox2 knockout fed CD

ABSTRACT: Rbfox2 is required for maintaining hepatic metabolic homeostasis, here we carry out RNAseq to of WT and aged matched littermate Rbfox2 knockout mice under high fructose in order to determine changes in alternative splicing and mRNA expression caused by knockout of this splicing factor in this metabolic environment.

RNAseq of livers from WT mice or livers with Rbfox2 knockout fed CD with 30% (w/v) Fructose in the drinking water

Project description:Rbfox2 is required for maintaining hepatic metabolic homeostasis. Here we carry out RNAseq to of WT and aged matched litter mate Rbfox2 knockout mice under CD or HFD in order to determine changes in alternative splicing and mRNA expression caused by knockout of this splicing factor in the context of metabolic health and disease.

Rbfox2 controls autoregulation in RNA binding protein networks

Project description:We generated a global analysis of Rbfox2 splicing regulation combined with a highly specific, single nucleotide-resolution Rbfox2 RNA binding map. We found that Rbfox2 regulates the splicing and expression of many previously unknown targets, and particularly a number of RNA binding proteins (RBPs), by modulating alternative splicing coupled-NMD. Based on our observations of RBP-Rbfox2 co-regulation with a polarity predicted by Rbfox2 binding, we propose a model whereby Rbfox2 tunes autoregulatory splicing events to control RBP expression levels and in turn alter their respective splicing networks. iCLIP for epitope-tagged Rbfox2 and control untagged Rbfox2; RNAseq of control and Rbfox2 knockdown in mouse embryonic stem cells

Rbfox2-coordinated alternative splicing of Mef2d and Rock2 controls myoblast fusion during myogenesis

Project description:Purpose: The goals of this study are to compare transcriptomes using RNA-seq of mouse myoblasts (C2C12 cell line) in undifferentiated and differentiated states and with siRNA-mediated knock down of the RNA binding proteins, Rbfox1 (only expressed in differentiated state) and Rbfox2 (expressed in both undifferentiated and differentiated states). Methods: Differentiated and undifferentiated C2C12 cultures treated with Rbfox1 (differentiated only) or Rbfox2 siRNAs or a mock siRNA transfection were used for RNA-Seq analysis using Illumina HiSeq2000. 101x2 paired-end RNA-seq reads were first uniquely aligned to the mouse genome (mm9) using TopHat 1.4.1. RSEM was used to count the number of reads mapped to genes using UCSC database, followed by edgeR to call differentially expressed genes with false discovery rate less than 0.01. Cufflinks was used to reconstruct isoforms and analyze alternative splicing and percent spliced in (PSI) was calculated. PSI values were validated by RT-PCR. Results: 58-88% of the RNA-seq reads from technical and biological replicates mapped uniquely to the mouse genome. Analysis of gene expression and alternative splicing changes are published in Singh et al. Molecular Cell (2014). Conclusions: Our study has identified gene expression and alternative splicing transitions that occur during myoblast differentiation, demonstrate that 30% of the splicing transitions are regulated by Rbfox2, demonstrated that Rbfox2 is required for a late step of myoblast differentiation and identified two Rbfox2-regulated splicing transitions that are required for differentiation. Undifferentiated and differentiated C2C12 cultures with Rbfox2 depletion or Rbfox1 depletion (differentiated only) in at least duplicate samples analyzed by deep sequencing on Illumina HiSeq2000.

Retinal transcriptome analysis of Rbfox2 deficient animals

Project description:Rbfox proteins regulate alternative splicing, mRNA stability and translation. These proteins are involved in neurogenesis and have been associated with various neurological conditions. We generated expression profile in adult and developing mouse retinas which lacks in Rbfox2 expression by RNA sequencing. The goals of this study is to identify the affected pathways in Rbfox2 KO mouse retina as well as potential splicing targets of Rbfox2.

RBFOX2 alter splicing outcome in distinct binding modes with multiple protein partners

Project description:RBFOX2 controls the splicing of a large number of transcripts implicated in cell differentiation and development. Parsing RNA-binding protein datasets, we uncover that RBFOX2 can interact with hnRNPC, hnRNPM and SRSF1 to regulate splicing of a broad range of splicing events using different sequence motifs and binding modes. Using immunoprecipitation, specific RBP knockdown, RNA-seq and splice-sensitive PCR, we show that RBFOX2 can target splice sites using three binding configurations: single, multiple or secondary modes. In the single binding mode RBFOX2 is recruited to its target splice sites through a single canonical binding motif, while in the multiple binding mode RBFOX2 binding sites include the adjacent binding of at least one other RNA binding protein partner. Finally, in the secondary binding mode RBFOX2 likely does not bind the RNA directly but is recruited to splice sites lacking its canonical binding motif through the binding of one of its protein partners. These dynamic modes bind distinct sets of transcripts at different positions and distances relative to alternative splice sites explaining the heterogeneity of RBFOX2 targets and splicing outcomes.
