Next Generation Sequencing Quantitative Analysis of Wild Type and RALY knock-down HCT 116 cells Transcriptomes

ABSTRACT: Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of gene expression and alternative RNA splicing. The goals of this study are to compare alternative splicing in RALY knock-down cells to identify the function of RALY in alternative splicing transcriptome profiling (RNA-seq) to microarray and quantitative reverse transcription polymerase chain reaction (qRT–PCR) methods and to evaluate protocols for optimal high-throughput data analysis Methods: mRNA profiles of RALY knock-dowed HCT 116 cells and non-silencing shRNA treated HCT 116 cells generated by deep sequencing, in duplicate, using Illumina Hiseq 2500. Results: Using an we mapped about more than 60 million reads per sample to the human genome (GRCh38) and identified 58,884 transcripts in WT and RALY knock-downed HCT 116 cells with Hisat2. rMATS analysis of RNA-seq data demonstrate significant effects of RALY on 4,046 skipped exon splicing and other alternative splicing events. Conclusions: Our study represents the first detailed analysis of transcriptomes in RALY KD cells, with biologic duplicates, generated by RNA-seq technology. The splicing analysis workflows reported here should provide a framework for the RALY function in the splicing.
