Genome wide RNA sequencing to profile response to IL-1 in control and IFT88 depleted cells
Purpose: RNA sequencing across whole genome downstream to IL-1 to investigate scope and nature of effect of IFT88 depletion Method: Control pool treated and IFT88 siRNA pool targeted Fibroblast-like chondrocytes were treated with or without IL-1B 10ng/ml  and RNA collected in triplicate at 0, 1, 2, 4, 8 and 24h. PolyA-selected sequencing libraries were prepared using the TruSeq protocol (Illumina). Libraries were subject to 75bp paired-end sequencing (Illumina HiSeq 4000) to an average depth of 28.5 million read pairs per sample and aligned to mouse genome with Hisat2. Results: Using time-course analysis (ImpulseDE2) the IL-1 response timecourse was determined (control-only) and intersected against the comparative case vs control analysis. Per-point differential expression analysis IFT88 vs control was performed using DESeq2. Conclusion: Demonstration of the effect of IFT88 depletion on IL-1 response signature over 24h. Overall design: Bulk RNA profiles of control siRNA targetted (control) and IFT88 siRNA (IFT88) treated fibroblastic chondrocyte line, both treated with and without IL-1 beta in quiescent state.
