Project description:Identification of alternative splicing events regulated by the splicing factor SRSF1 using data from exon-junction microarray technologies
Project description:In this study, we compare the performance of RNA-seq (Illumina HiSeq) and junction arrays (Affymetrix Human Transcriptome array) for the analysis of splicing events. Three different cell lines were treated with CX-4945, a drug that severely affects splicing. To make a fair comparison, we developed EventPointer, an algorithm that detects and labels alternative splicing events in both junction arrays and RNA-seq. Common results and discrepancies between both technologies were validated or resolved by more than 200 PCRs.

Project description:We describe the application of a new microarray platform, which combines information from exon body and splice-junction probes, to analyze the regulation of 3126 alternative splicing events in ten mouse tissues. The details of the methods and algorithms are described in this paper: Revealing global regulatory features of mammalian alternative splicing using a quantitative microarray platform (Molecular Cell, Dec., 2004) Keywords = A new quantitative alternative splicing microarray platform
Project description:RNPS1 is a splicing regulatory protein and a component of the ASAP/PSAP complex, which is associated with the exon junction complex and modulates alternative splicing. It was previously postulated that the isolated RRM domain of RNPS1 in complex with ASAP/PSAP is able to regulate certain alternative splicing events. We aimed to investigate in HeLa Tet-Off cells which alternative splicing events are rescued by the expression of the isolated RRM domain of RNPS1 in a RNPS1 knockdown background by using RNA-Seq analyses. The rescue construct was stably integrated into the genome using the PiggyBac transposon system. As controls, either Luciferase (Luc) siRNA was used or RNPS1 was knocked down without rescue.

It was previously postulated that the isolated RRM domain of RNPS1 in complex with ASAP/PSAP is able to regulate certain alternative splicing events. We aimed to investigate in Flp-In T-REx 293 cells which alternative splicing events are rescued by the expression of the wild type RNPS1 or the isolated RRM domain of RNPS1 in a RNPS1 knockdown background by using RNA-Seq analyses. The rescue construct was stably integrated into the genome using the PiggyBac transposon system. As controls, either Luciferase (Luc) siRNA was used or RNPS1 was knocked down without rescue.
