Project description:Purpose: To characterize the differential microRNA expression profiles and microRNA editing upon PRRSV infection, using NGS techonology, we sequenced small RNAs of the lungs of Tongcheng and Landrace pigs before (0 dpi) and after (3, 5, 7 dpi) infection with high-pathogenic PRRSV (HP-PRRSV). Methods: The miRNA expression profiles of the lungs of Tongcheng and Landrace pigs before (0 dpi) and after (3, 5, 7 dpi) HP-PRRSV infection were produced by using solexa platform. The raw reads with low qualities were filtered and the clean high quality reads were mapped to Ensembl Sus reference genome 10.2.71 using BWA. The unique mapped reads were retained for microRNA expression analysis. The raw reads counts of each microRNA were calculated by perl scripts and the differentially expressed microRNA (Fold change >2; FDR <0.05) were called using edgeR. The microRNA editing was identified using the methods described by Alon, S. and E. Eisenberg. Methods Mol Biol, 2013. Further analysis of microRNA editing was performed with perl scripts.
Project description:We established three new rhesus embryonic stem cells lines and conducted their microRNA profilings by Solexa sequencing. Sequencing of small RNA libraries yielded 12.66 million, 13.12 million and 11.57 million raw reads from IVF1.2, IVF3.2 and IVF3.3, respectively. After filtering, we obtained 10.89 million (IVF1.2), 10.60 million (IVF3.2) and 9.26 million (IVF3.3) clean reads (18-30nt).
Project description:Purpose: The goal of this study is to compare endothelial small RNA transcriptome to identify the target of OASL under basal or stimulated conditions by utilizing miRNA-seq. Methods: Endothelial miRNA profilies of siCTL or siOASL transfected HUVECs were generated by illumina sequencing method, in duplicate. After sequencing, the raw sequence reads are filtered based on quality. The adapter sequences are also trimmed off the raw sequence reads. rRNA removed reads are sequentially aligned to reference genome (GRCh38) and miRNA prediction is performed by miRDeep2. Results: We identified known miRNA in species (miRDeep2) in the HUVECs transfected with siCTL or siOASL. The expression profile of mature miRNA is used to analyze differentially expressed miRNA(DE miRNA). Conclusions: Our study represents the first analysis of endothelial miRNA profiles affected by OASL knockdown with biologic replicates.
Project description:A cDNA library was constructed by Novogene (CA, USA) using a Small RNA Sample Pre Kit, and Illumina sequencing was conducted according to company workflow, using 20 million reads. Raw data were filtered for quality as determined by reads with a quality score > 5, reads containing N < 10%, no 5' primer contaminants, and reads with a 3' primer and insert tag. The 3' primer sequence was trimmed and reads with a poly A/T/G/C were removed
