(Submitter supplied) This study compares differences in gene expression between RNAs from lung and bronchial lymph node (BLN) tissue of high (H), low (L) PRRSV burden pigs or a pooled reference (R) using the swine protein-annotated long oligonucleotide microarray. Pathway analyses were carried out on a large scale to determine biological processes, pathways and networks that differ between the H, L and R responses.

(Submitter supplied) The presence of variability in the response of pigs to Porcine Reproductive and Respiratory Syndrome virus (PRRSv) infection, and recent demonstration of significant genetic control of such responses, leads us to believe that selection towards more disease resistant pigs could be a valid strategy to reduce its economic impact on the swine industry. To find underlying molecular differences in PRRS susceptible versus more resistant pigs, 100 animals with extremely different growth rates and viremia levels after PRRSv infection were selected from a total of 600 infected pigs. more...

(Submitter supplied) 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. more...

(Submitter supplied) Porcine Reproductive and Respiratory Syndrome Virus (PRRSV) infection of 3rd trimester pregnant pigs can result in transmission of the virus to the fetus and ultimately death in utero or postnatally. Little is known about the immune response to infection at the maternal-fetal interface and in the fetus itself, or the molecular events behind virus transmission and disease progression in the fetus. To investigate these processes, RNA-sequencing of two tissues, uterine endothelium adjacent to the umbilical attachment site and fetal thymus, was performed 21 days post challenge on four groups of fetuses selected from a large PRRSV challenge experiment of pregnant gilts.

(Submitter supplied) Porcine reproductive and respiratory syndrome caused by porcine reproductive and respiratory syndrome virus (PRRSV) is an infectious disease characterized by severe reproductive deficiency in pregnant sows, respiratory symptoms in piglets, and high mortality. In this study, we employed Affymetrix microarray chip technology to compare the gene expression profiles of lung tissue samples from Dapulian (DPL) pigs (a Chinese indigenous pig breed) and Duroc×Landrace×Yorkshire (DLY) pigs after infection with PRRSV. more...

(Submitter supplied) 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. more...

(Submitter supplied) Porcine reproductive and respiratory syndrome (PRRS) has been one of the most economically important diseases affecting swine industry worldwide and causes great economic losses each year. PRRS virus (PRRSV) replicates mainly in porcine alveolar macrophages (PAMs) and dendritic cells (DCs) and develops persistent infections, antibody-dependent enhancement (ADE), interstitial pneumonia and immunosuppression. more...

(Submitter supplied) Porcine reproductive and respiratory syndrome virus (PRRSV) is a causative agent of an important infectious disease causing serious economic losses to swine industry called PRRS (porcine reproductive and respiratory syndrome). The clinical signs of this syndrome indcude respiratory disorders, abortions and variable mortality in piglets. To compare the virulence of highly diverse East European strains belonging to subtype 2 (Russian strain ILI and Belarusian strain BOR) and Danish strain from classical subtype 1 (DAN) the experimental study enrolling infection of piglets was performed. more...

(Submitter supplied) Piglets were raised in isolation facilities from 10 days to 7 weeks of age at the National Animal Disease Center. Bacteriological culture of rectal swabs was performed twice to confirm that all pigs were free of Salmonella spp. Three control pigs were necropsied on experimental day -3. On day 0, pigs in the infected group were intranasally challenged with 1 x 109 CFU S. Choleraesuis X3246. Lung samples were aseptically collected from three 24 h and three 48 h post infection pigs and immediately frozen in liquid nitrogen for future mRNA isolation. more...

(Submitter supplied) Transcriptional profiling of 25d old piglets comparing control untreated suckling jejunum with weaned piglets' jejunum. The goal was to gain new insight into the interaction between weaning and intestinal function.A keen interest is paid in deciphering expression changes of apoptosis or cell cycle control genes. The statistical analysis of gene ontology revealed that most of these altered genes are metabolic-related enzymes and regulators which may involved in the biological regulation, developmental process, and cellular process. more...

(Submitter supplied) 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. more...
