Next Generation Sequencing Facilitates Quantitative Analysis of Taurine Promoted Transcriptomes

ABSTRACT: Purpose: Taurine promotes the activation of plasmacytoid dendritic cells. The goals of this study are to identify genes and pathways invovled in the regulation. Methods: Mouse plasmacytoid dendritic cells were stimulated with R837, together with or without taurine for 12 hours. Then, the next-generation libraries of mRNA were prepared using VAHTS mRNA-seq v2 Library Prep Kit for Illumina® (Vazyme, Nanjing, China). The Library quality was determined by Bioanalyzer 4200 (Agilent, Santa Clara, CA, USA). Then the mRNA-seq libraries were sequenced in HiSeq ⅹ10 system (Illumina, San Diego, CA, USA) on a 150bp paired-end run. The differentially expressed genes were selected as having more than 1 fold difference in their geometrical mean expression between the compared groups and a statistically significant p-value (<0.05) by analysis of DEseq2. The GO analysis on differentially expressed genes was performed with an R package: Clusterprofiler using a p<0.05 to define statistically enriched GO categories. Pathway analysis was used to determine the significant pathway of the differential genes according to Kyoto Encyclopedia of Genes and Genomes Database (http://www.genome.jp/kegg/) and DAVID Bioinformatics Resources 6.8 (https://david.ncifcrf.gov/). Results: Genes in the TLR7-IRF7 pathway were augmented by taurine. As a result, the production of type I IFNs increased upon taurine treatment.

microRNA changes during pDC activation

Project description:To identify microRNA changes during plasmacytoid dendritic cell (PDC) activation, we stimulated human primary PDCs with 10ug/ml R837 (Invivogen, San Diego, CA, USA) for 4 hours. Purified human pDCs were divided into two parts: one was cultured with medium alone, another was cultured with R837. 4 hours later, cells were collected and total RNA was extracted for the TaqManM-BM-. Human MicroRNA Arrays. The experiment was duplicated (sample1 and sample2).

Whole genome transcriptome profiling of Thellungiella salsuginea guard cells under saline growth conditions

Project description:The overall objective was to document transcriptomic changes in the guard cells of Thellungiella salsuginea under short (1x) - and long-term (3x) saline growth conditions. For that. microarray analysis was performed using a 60-mer oligonucleotide probe array from Agilent (44 K, design number 031554, Santa Clara, CA, USA). It was clearly observed that salt salinity alters the transcriptomic landscape of Thellungiella guard cells. However, changes in gene expression were evident under 3x saline growth conditions compared to non-saline conditions. Similarly, more GO terms were significantly enriched in differentially expressed guard cell genes of 3x salt than 1x salt treated plants.

CircRNA sequencing in peripheral blood mononuclear cells from Ankylosing Spondylitis patients and healthy controls

Project description:To identify the expression profiles of circRNAs in peripheral blood mononuclear cells (PBMCs) from Ankylosing Spondylitis (AS) patients and healthy controls, we used circRNA sequencing to detect circRNA in 3 samples of PBMCs from AS patients and 3 samples of PBMCs from healthy controls. In brief, total RNA was extracted and purified using Magen Hipure Total RNA Mini Kit (Magen, Guangzhou, China), followed by constructing RNA sequencing libraries with KAPA RNA HyperPrep Kit with RiboErase (Kapa Biosystems, Inc., MA, USA). After the construction of RNA sequencing libraries, Qubit 3.0 fluorometer (Invitrogen, CA, USA) and the Agilent 2100 bioanalyzer (Applied Biosystems, CA, USA) were used for quality control. Then, the PE150 mode of HiSeq X10 (Illumina Inc., CA, USA) was used for sequencing. Differentially expressed circRNAs were screened with criteria of fold-change>1.5 and p<0.05.
