(Submitter supplied) Background: The gonadotropin-induced resumption of oocyte meiosis in preovulatory follicles is preceded by expression of epidermal growth factor (EGF)-like peptides, amphiregulin (AREG) and epiregulin (EREG), in mural granulosa and cumulus cells. Both the gonadotropins and the EGF-like peptides possess the capacity to stimulate resumption of oocyte meiosis in vitro via activation of a broad signaling network in cumulus cells. more...

(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) 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...

However, strategies such as vaccination and good biosecurity are not consistently successful to eliminate PRRSV. Though some interesting pathways have been tentatively examined recently, host molecular pathways utilized by PRRSV and the protective immune responses in resistant to PRRSV are largely unknown. more...

(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) 510 F2 Duroc X Pietrain pigs together with their parents and grandparents from a resource population at Michigan State University were genotyped for 124 microsatellite markers. Transcriptional profiling was performed on a subset of 176 F2 pigs using a 70-mer long oligonucleotide microarray containing 20,400 oligos (GPL7435). Pigs were selected for transcriptional profiling using a selective phenotyping strategy which consisted in choosing the two extreme males and females for a trait of interest within each litter.

(Submitter supplied) The aim of this study was to identify differentially expressed genes and pathways in longissimus dorsi (LD) of pigs at 40 and 70 d of gestation (stages encompassing the transition from primary to secondary fiber formation) in U.S. commercial crossbred pigs (Yorkshire x Landrace) and Brazilian native Piau pigs. We confirmed the expression patterns for a subset of genes by qRT-PCR. Pathway analysis revealed functionally related genes, and indicated commonalities and differences between the breed types and developmental ages evaluated. more...

(Submitter supplied) In this study we evaluate the Swine Protein-Annotated Oligonucleotide Microarray by profiling the expression of transcripts in four porcine tissues. We validate the hybridization results by comparative analysis of expression in human orthologs, confirm expression patterns for a subset of genes by QPCR, and assess the usefulness of designed control oligonucleotides. Simple descriptive diagnostic analyses of PM/MM probe sets introduced in this paper are useful to detect non-specific hybridization. more...
