The cells received treatment with siRNA twice - 24h post seeding, and 48h post seeding when splitting into a new plate. Transfections of splice-switching oligonucletides (SSOs) targeting mutually exclusive U2AF1 exons were carried out in 6- or 12- well plates using jetPRIME (Polyplus) according to manufacturer's recommendations. The cells received treatment with SSO twice - 24h post seeding, and 48h post seeding when splitting into a new plate. PolyA library selection was performed using NEBNext poly(A) mRNA magnetic isolation module (E7490L) according to the manufacturer's specifications. A human/mouse/rat Ribo-Zero rRNA Removal Kit (Cambio/Epicentre) was used according to the manufacturer's specifications. Size-selected and multiplexed libraries were sequenced using Illumina HiSeq 2500 using paired-end sequencing. Sequence alignment was performed using Bowtie 2 and TopHat 2 against genome and transcriptome references (hg19, UCSC). The transcriptome reference was altered to include U2AF1 isoform s. Following alignment, sequences recognised as originating from mtRNA, rRNA, and tRNA were removed. Protocol Hardware Illumina HiSeq 2500 IRIDIS 4 High Performance Computing Cluster Protocol Software Bowtie (v. 2.1.0), TopHat (v. 2.0.9) Term Source Name EFO Term Source File http://www.ebi.ac.uk/efo/ Term Source Version Comment[AEExperimentType] RNA-seq of coding RNA Comment[AEExperimentDisplayName] RNA-Seq data of U2AF1 isoform depletion experiments Comment[SecondaryAccession] ERP006200 Comment[SequenceDataURI] http://www.ebi.ac.uk/ena/data/view/ERR553454-ERR553469 SDRF File E-MTAB-2682.sdrf.txt
