MicroRNAs (miRNAs) are a class of small (approximately 22-nucleotide) regulatory molecules that block translation or induce degradation of target mRNAs. These have been identified in a wide range of organisms, including viruses. In particular, the oncogenic gammaherpesviruses Kaposi's sarcoma herpesvirus and Epstein-Barr virus encode miRNAs that could(More)
Salmonella enterica is a facultative intracellular pathogen that is capable of causing disease in a range of hosts. Although human salmonellosis is frequently associated with consumption of contaminated poultry and eggs, and the serotypes Salmonella gallinarum and Salmonella pullorum are important world-wide pathogens of poultry, little is understood of the(More)
Microarrays containing 1,126 nonredundant cDNAs selected from a chicken activated T-cell expressed sequence tag database (http://chickest.udel.edu) were used to examine changes in host cell gene expression that accompany infection of chicken embryo fibroblasts (CEF) with Marek's disease virus (MDV). Host genes that were reproducibly induced by infection of(More)
Eight chicken cytokine genes (IL-1beta, IL-2, IL-8, IL-15, IFN-alpha, IFN-gamma, TGF-beta4, lymphotactin) were evaluated for their adjuvant effect on a suboptimal dose of an Eimeria DNA vaccine carrying the 3-1E parasite gene (pcDNA3-1E). Chickens were given two subcutaneous injections with 50 microg of the pcDNA3-1E vaccine plus a cytokine expression(More)
The application of microarray technology to functional genomic analysis in the chicken has been limited by the lack of arrays containing large numbers of genes. We have produced cDNA arrays using chicken EST collections generated by BBSRC, University of Delaware and the Fred Hutchinson Cancer Research Center. From a total of 363,838 chicken ESTs(More)
The use of new, deep sequencing technologies has greatly accelerated microRNA discovery. We have applied this approach to the identification of chicken microRNAs and to the comparison of microRNAs in chicken embryo fibroblasts (CEF) infected with Marek's disease virus (MDV) to those present in uninfected CEF. We obtained 125,463 high quality reads that(More)
Since the sequencing of the genome and the development of high-throughput tools for the exploration of functional elements of the genome, the chicken has reached model organism status. Functional genomics focuses on understanding the function and regulation of genes and gene products on a global or genome-wide scale. Systems biology attempts to integrate(More)
Members of the Quiescin-sulfhydryl oxidase (QSOX) family utilize a thioredoxin domain and a small FAD-binding domain homologous to the yeast ERV1p protein to oxidize sulfhydryl groups to disulfides with the reduction of oxygen to hydrogen peroxide. QSOX enzymes are found in all multicellular organisms for which complete genomes exist and in Trypanosoma(More)
Marek's disease virus (MDV), a herpesvirus that causes a lymphoproliferative disorder in chickens, encodes a number of microRNAs derived primarily from two locations in the MDV genome. One cluster of microRNA genes flanks the meq oncogene, and a second cluster is found within the latency-associated transcript (LAT) region. The sequences of MDV microRNAs(More)
