Project description:The study demonstrated the gene expression through microarray analysis of total mRNA in rams experimentally infected with a rough (R) virulent strain of Brucella ovis in reproductive organs (epididymus, testicles, ampolae, vesicular glands, bulbourethral glands) and a pool of lymph nodes (inguinal and scrotal) at three different times: acute phase (60 days post challenge [dpc]), chronic phase 1 (120dpc), and chronic phase 2 (240dpc) of infection. To further define the gene expression changes associated with infected rams, the profiles of a control group (0 dpc) of rams was compared using the Affymetrix Bovine Genome Array. Of the 23,000 genes that were analyzed on the array, B. ovis infection in rams’ tissues revealed 139, 930 and 744 Differentially Expressed Genes (DEGs) in the acute, chronic 1, and chronic phase 2 of infection, respectively. Among the three phases of infection, 44 DEGs (30 known and 14 unknown genes) were expressed in common. The biological functions of immune cell trafficking, immunological disease, infectious disease, inflammatory disease, inflammatory response and cellular movement were significant at the three phases of infection. The results support the first microarray analysis of ram tissues infected with an R strain of B. ovis. A total of twelve 12-month-old healthy Santa Inês rams, previously diagnosed as negative for brucellosis/visna maedi/toxoplasmosis/neosporosis, were selected for the study. The rams were kept in an isolated pen and experimentally challenged with a rough (R) virulent B. ovis PA strain (ATCC 25840). For the experiment, the rams were classified during the course of infection according to time: 0 dpc (control), 60 dpc (acute phase), 120 dpc (chronic phase 1) and 240 dpc (chronic phase 2). For each time, the tissues epididymus, testicles, ampolae, vesicular glands, bulbourethral glands, and a pool of lymph nodes (inguinal and scrotal) were collected. Three rams were euthanized and necropsied for tissues collection purposes for each time. To define the gene expression changes associated with infected rams, the profile of a control group (0 dpc) of rams was compared using microarray technology. REPLACE This dataset includes control samples and acute phase samples.

Project description:MicroRNAs (miRNAs) are short endogenous, single-stranded, non-coding small RNA molecules of about 22 nucleotides in length. They regulate gene expression post-transcriptionally by silencing mRNA molecules and they regulate many physiological processes. Visna-Maedi virus (VMV) is a lentivirus that causes Visna-Maedi disease (VM) in sheep characterised by pneumonia, mastitis, arthritis and encephalitis; and affects cells of the monocyte/macrophage lineage. So far, there are no studies in the role of miRNAs in this viral disease. Using RNAseq technology and bioinformatics analysis the expression of miRNAs in different phases of the disease were studied. A total of 212 miRNAs were found, of which 46 were conserved sequences found for the first time in sheep and 12 were completely novel. Differential expression analysis showed changes in several miRNAs comparing uninfected and seropositive groups, but did not detect significant differences between seropositive asymptomatic and diseased sheep. The high increase in expression of oar-miR-21 agrees with the increase of the same miRNA detected in other viral diseases. In addition, the target prediction of dysregulated miRNAs revealed that they control genes involved in proliferation-related signalling pathways like PI3K-Akt, AMPK and ErbB.

Project description:To test if LEDGF/p75 influences distribution of Maedi-visna virus (MVV) integration sites, we infected human HEK293T, LKO (PSIP1-null), and LHKO (PSIP1/HDGFL2-null) cells with MVV-derived vector. Genomic DNA was isolated from infected cells, and chromosomal junctions at integrated U5 vDNA ends were amplified using linker-mediated PCR, sequenced using Illumina technology and mapped to human genome.
