Microarray analysis of miRNAs involved in Porcine Alveolar Macrophages at the early stage of porcine reproductive and respiratory syndrome virus infection [LCS_miRPig_17]

ABSTRACT: By analyzing the changes of miRNAs of piglet PAMs 6h after PRRSV infection,we can find porcine miRNAs associated with viral infection and possible target sites in both PRRSV and pig genome and their roles in protection against viral infections. Then these targets will screened by bioinformatics methods to find the susceptibility genes, resistance genes and immune related genes, and formed molecular biology network of miRNAs at gene and protein level .

Then these targets will screened by bioinformatics methods to find the susceptibility genes, resistance genes and immune related genes, and formed molecular biology network of miRNAs at gene and protein level . PAM cells were isolated from 60d old healthy piglets and inoculated with HuN4,a strain of highly pathogenic porcine reproductive and respitory syndrome virus (HP-PRRSV) and were collected at 6h post-inoculation (pi). The uninfected cells served as mock-infected cells.The miRNA chip was according to the porcine miRNA sequences in Sanger miRBase Release 17.0 (http://www.sanger.ac.uk/Software/Rfam/mirna/)added with some miRNAs we found in reference. Microarray hybridization and data analysis helps to find the susceptibility genes, resistance genes and immune related genes, and formed molecular biology network of miRNAs at gene and protein level .

Microarray analysis of miRNAs involved in Porcine Alveolar Macrophages at the early stage of porcine reproductive and respiratory syndrome virus infection [LCS_miRPig_18]

Project description:By analyzing the changes of miRNAs of piglet PAMs at different time points after PRRSV infection,we can find porcine miRNAs associated with viral infection and possible target sites in both PRRSV and pig genome and their roles in protection against viral infections. Then these targets will screened by bioinformatics methods to find the susceptibility genes, resistance genes and immune related genes, and formed molecular biology network of miRNAs at gene and protein level . PAM cells were inoculated with HuN4, and were collected at 12h and 24h post-inoculation (pi), respectively. The uninfected cells served as mock-infected cells.The miRNA chip was according to the porcine miRNA sequences in Sanger miRBase Release 18.0 (http://www.sanger.ac.uk/Software/Rfam/mirna/)added with some miRNAs we found in reference. Then we confirmed the expression change of some important miRNAs by qRT-PCR

Transcriptome analysis of the mRNAs and lncRNAs in porcine alveolar macrophages in response to porcine reproductive and respiratory syndrome virus or IFN-a at different time points

Project description:Purpose:We performed next-generation RNA sequencing and a comprehensive bioinformatics analyses to characterize the transcriptome landscapes, including mRNAs and long noncoding RNAs (lncRNAs) in PRRSV-infected PAMs or IFN-stimulated PAMs at different time points. Conclusions: We showed that PRRSV infection displays different transcriptome profiles of PAMs, and the aberrant function of PAMs may be reflected by significant down-regulation of essential genes at the transcriptome levels. In addition, we discovered a great amount of differentially expressed lncRNAs, including lncRNA XR_297549.1, which is highly expressed and predicted to both cis- and trans-regulate its neighboring gene PTGS2.In addition, In order to expand our understanding of these IFN-induced non-coding transcripts, especially long non-coding RNAs (lncRNAs), we performed next-generation RNA sequencing and a comprehensive bioinformatics analysis of porcine alveolar macrophages (PAMs) stimulated with pig-IFN-? for 6h and 12h, respectively. A great amount of differentially expressed mRNAs and lncRNAs were identified, and several lncRNAs are of great interest for further investigation as their potential role in regulation of the well-characterized antiviral genes, such as OAS1, PML and ISG15.

PRRSV-infection of porcine alveolar macrophages

Project description:The goal of this study was to produce a deep, global analysis of gene expression changes that occured following infection of normal porcine alveolar macrophages (PAMs) with PRRSV. The goal was to examine the gene expression changes to help determine the mechanisms that result in reduced function and immunosuppression observed in PRRSV-infected pigs. Keywords: time course of infection The PAMs were infected in culture at an MOI of 10 with PRRSV strains VR-2332 and incubated at 37C until 6, 12, 16 or 24 hours post infection. Total cellular RNA was collected from each at the appropriate time. SAGE libraries were prepared from each infected time point as well as from noninfected PAMs. The SAGE libraries were sequenced to at least 95,000 tags each.

RNA-sequencing analysis of gilt blood gene expression during Porcine Reproductive and Respiratory Syndrom Virus infection

Project description:Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of pregnant females causes fetal death and increased piglet mortality, but there is substantial variation in the extent of reproductive pathology between individual dams. This study used RNA-sequencing to characterize the whole blood transcriptional response to PRRSV in pregnant gilts during the first week of infection, and attempted to identify gene expression signatures associated with a low or high level of fetal mortality at necropsy, 21 days post-inoculation.

Genome-wide transcriptional response of primary alveolar macrophages (PAMs) following infection with porcine circovirus type 2

Project description:Porcine alveolar macrophages (PAMs) play impoartant role in innate immunity. Porcine circovirus type 2 (PCV2) has been identified as the causal agent of postweaning multisystemic wasting syndrome, an economically important multifactorial disease of the swine industry worldwide. We used microarrays to study the transcriptome of PAMs infection with PCV2. PAMs were collected by bronchoalveolar lavage from health piglets (free of PCV2, PRRSV, PRV, CSFV, PPV), and PAMs were cultured for 48 hours and inoculated with 5 moi of PCV2.

Whole blood response of Pigs to infection with Porcine Reproductive and Respiratory Syndrome Virus (PRRSV)

Project description:Porcine reproductive and respiratory disease (PRRS) is the most important disease in swine industry worldwide. However, strategies such as vaccination and good biosecurity are not consistently successful to eliminate PRRSV. Although some gene expression pathways have been explored recently, host molecular pathways blocked by PRRSV and the protective immune response expressed in pigs resistant to PRRSV are largely unknown. In order to answer these questions, we herein characterize changes in blood gene expression in pigs responding differentially to infection with a well characterized type 2 (North American) PRRSV isolate. Samples are those collected through the PRRS Host Genetics Consortium (PHGC). Samples were those from Tempus tube collected blood of PHGC pigs selected from four response groups according to their serum viral load (0-21 days post infection) and weight gain (0-42 dpi) and characterized as low vs. high viral load and low vs high weight gain . block reference design was used to accommodate samples from 4 treatment groups.
