Project description:We used the high-throughput sequencing and inhibitors to screen microRNAs that play the role in anti-porcine reproductive and respiratory syndrome virus (PRRSV) responses in porcine alveolar macrophages (PAMs).
Project description:Porcine reproductive and respiratory syndrome (PRRS), caused by PRRS virus (PRRSV), is the most economically important disease in pig populations. Lung damage is one major pathological condition following PRRSV infection, often leading to animal death. In vivo, PRRSV productive infection occurs predominately in alveolar macrophages of the lung. Here, transcriptome profiling of pulmonary alveolar macrophages (PAMs) from Tongcheng piglets pre- and post- infection of highly pathogenic PRRSV has been performed using porcine Affymetrix GeneChip.
Project description:Porcine alveolar macrophages were challenged in vitro with a low virulent strain of the Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) to identify and characterize the population of host genes subjected to miRNA post-transcriptional regulation durign early viral infection. We employed a high-throughput biochemical assay, i.e. the immunoprecipitation of RISCs followed by microarray analysis of the RISC-bound miRNA targets (RIP-Chip). qPCR analyses were carried out to validate the resolution of the microarray and to determine levels of expression of a panel of eight miRNAs (ssc-miR-142-3p, ssc-miR-142-5p, ssc-let-7f, miR-146a-5p, miR-155-5p, ssc-miR-181a, ssc-miR-21 and ssc-miR-335).

Project description:In vivo microarray study of global gene expression changes in peripheral blood mononuclear cells (PBMCs) of Pietrain pigs during the stage of inatte immune and adaptive immune response to porcine reproductive and respiratory syndrome virus vaccination.
Project description:Transcriptomes analysis of long noncoding RNA (lncRNA) and mRNA expression profiles of the porcine alveolar macrophages (PAMs) after porcine reproductive and respiratory syndrome virus (PRRSV) infection in vitro. We obtained 105,627,026 clean reads from 109,443,286 raw reads. A total of 951 annotated and 751 novel lncRNAs were identified. PAMs showed distinct transcriptome profiles after PRRSV infection. It was observed that 126 lncRNAs and 753 mRNAs were differentially expressed between PRRSV-infected and control group PAMs.
Project description:Porcine reproductive and respiratory syndrome (PRRS), which caused by the porcine reproductive and respiratory syndrome virus (PRRSV), is a serious viral disease affecting global swine industry. At present, PRRSV vaccines fail to prevent this disease. Consequently, new antiviral strategies to compensate for the inefficacy of available vaccines are urgently required. Lysine acetylation is an important post-translational modification (PTM) regulating an array of pathological and physiological conditions. In this study, we profiled the global acetylome using acetylation specific antibody based enrichment and Tandem mass tag (TMT) label LC-MS in PRRSV-infected pulmonary alveolar macrophages (PAMs). As a result, 3731 lysine acetylation sites on 1421 cellular proteins were identified and quantified 6 hours post infection (hpi). Bioinformatics analysis of the differentially acetylated proteins revealed their involvement in various biological processes, including the host immune response and energy metabolism.
