Project description:Background: Whole transcriptome sequencing (RNA-seq) represents a powerful approach for whole transcriptome gene expression analysis. However, RNA-seq carries a few limitations, e.g., the requirement of a significant amount of input RNA and complications led by non-specific mapping of short reads. The Ion AmpliSeqTM Transcriptome Human Gene Expression Kit (AmpliSeq) was recently introduced by Life Technologies as a whole-transcriptome, targeted gene quantification kit to overcome these limitations of RNA-seq.To assess the performance of this new methodology, we performed a comprehensive comparison of AmpliSeq with RNA-seq using two well-established next-generation sequencing platforms (Illumina HiSeq and Ion Torrent Proton). We analyzed standard reference RNA samples and RNA samples obtained from human induced pluripotent stem cell derived cardiomyocytes (hiPSC-CMs). Results: Using published data from two standard RNA reference samples, we observed a strong concordance of log2 fold change for all genes when comparing AmpliSeq to Illumina HiSeq (Pearson’s r=0.92) and Ion Torrent Proton (Pearson’s r=0.92). We used ROC, Matthew’s correlation coefficient and RMSD to determine the overall performance characteristics. All three statistical methods demonstrate AmpliSeq as a highly accurate method for differential gene expression analysis. Additionally, for genes with high abundance, AmpliSeq outperforms the two RNA-seq methods. When analyzing four closely related hiPSC-CM lines, we show that both AmpliSeq and RNA-seq capture similar global gene expression patterns consistent with known sources of variations. Conclusions: Our study indicates that AmpliSeq excels in the limiting areas of RNA-seq for gene expression quantification analysis. Thus, AmpliSeq stands as a very sensitive and cost-effective approach for very large scale gene expression analysis and mRNA marker screening with high accuracy.

Project description:CD3+ T cells were enriched using the EasySep human T cell isolation kit (Stem cell technology). T cells from normal controls or patients with CARD9 mutations were co-cultured with monocytes of one normal control in the presence of heat killed candida. After 3 days, T cell were enriched again to remove the monocytes and total RNA was extracted from the T cells for the RNA-sequencing (RNASeq) evaluation. Targeted RNA sequencing library preparation was carried out using the Ion AmpliSeq Transcriptome Human Gene Expression Kit (Life Technologies), which profiles more than 20,000 human genes; each amplicon (~150 bp) represents a unique targeted gene (one transcript per gene). For library preparation, each sample was run in duplicate, and a cDNA library was generated from a minimum of 10 ng of total RNA. The cDNA was barcoded and amplified with Ion AmpliSeq technology, and the amplified cDNA Libraries were evaluated for quality and quantified with Agilent Bioanalyzer high-sensitivity chip. Libraries were then diluted to 100 pM and pooled equally, with 4 individual samples per pool. Pooled libraries were amplified and enriched with the Ion Chef System (Life Technologies). Templated libraries were then sequenced on an Ion Torrent Proton sequencing system (Life Technologies) with Ion PI HiQ kit and chip version 3. We performed gene-level differential expression analysis of targeted RNASeq data using R (v.3.5.3) and the Bioconductor packages DESeq2 (v.1.22.2).
