Project description:We hypothesized that the gene expression pattern of OvHV-2 may be important to understand the pathogenesis of malignant catarrhal fever (MCF). Therefore, RNA was extracted from lymph nodes of animals with MCF and healthy controls to be analyzed by a custom-made microarray. Two regions on the viral genome were transcriptionally active, one encoding a homologue to the latency-associated nuclear antigen (ORF73) of other gamma herpesviruses, the other with no predicted open reading frame. Keywords: Disease state analysis

Project description:We hypothesized that the relative abundances of host cell transcripts in lymph nodes of animals with malignant catarrhal fever (MCF), compared to healthy controls, may be used to identify pathways that may help to explain the pathogenesis of MCF. Therefore, an abundance of host cell gene expression patterns in lymph nodes of animals with MCF and healthy controls were analyzed by microarray. Indeed, a vast number of genes related to inflammatory processes, lymphocyte activation, cell proliferation and apoptosis were detected at different abundances. However, the IL-2 transcript was eminent among the transcripts, which were, compared to healthy controls, less abundant in animals with MCF. Compared to healthy cattle, bovines with MCF appear to mimic an IL-2 knockout phenotype that has been described in mice. This supports the hypothesis that immunopathogenic events are linked to the pathogenesis of MCF. IL-2-deficiency may play an important role in the process. Keywords: disease state analysis

Project description:Extracellular vesicles (EVs) are key mediators of intercellular communication, and often play critical roles in host-parasite interactions by facilitating parasite’s physiology and pathogenesis. Theileria annulata, an apicomplexan parasite, induces profound changes in host cells, leading to uncontrolled proliferation, apoptosis resistance, and increased invasiveness. In this study, we performed the comprehensive proteomic and small RNA analysis of EVs isolated from a T. annulata Kashi isolate-infected bovine lymphocyte cell line (TaXJS), B cell line (TaBC), dendritic cell line (TaDC), and from the sera of cattle before and after infection. Our label-free LC-MS/MS proteomics identified 2580 proteins, while small RNA sequencing revealed 6635 miRNAs associated with parasite development, host invasion, and immune evasion. Functional enrichment analyses recognized vesicular components involved in key pathways of the parasite-host such as ECM-receptor interaction, oxidative phosphorylation, and proton transport. These findings highlight the potential of Theileria-derived EVs in modulating host responses and their potential as therapeutic and vaccine targets.

Project description:With regulatory roles in development, cell proliferation and disease, micro-RNA (miRNA) biology is of great importance and a potential key to novel RNA-based therapeutic regimens. Biochemically based sequencing approaches have provided robust means of uncovering miRNA binding landscapes on transcriptomes of various species. However, a current limitation to the therapeutic potential of miRNA biology in cattle is the lack of validated miRNAs targets. Here, we use cross-linking immunoprecipitation (CLIP) of the Argonaute (AGO) proteins and unambiguous miRNA-target identification through RNA chimeras to define a regulatory map of miRNA interactions in the cow (Bos taurus). The resulting interactome is the deepest reported to date for any species, demonstrating that comprehensive maps can be empirically obtained. We observe that bovine miRNA targeting principles are consistent with those observed in other mammals. Motif and structural analyses define expanded pairing rules with most interactions combining seed-based pairing with distinct, miRNA-specific patterns of auxiliary pairing. Further, miRNA-target chimeras had predictive value in evaluating true regulatory sites of the miR-17 family. Finally, we define miRNA-specific targeting for >5000 mRNAs and determine gene ontologies (GO) for these targets. This confirmed repression of genes important for embryonic development and cell cycle progress by the let-7 family, and repression of those involved in cell cycle arrest by the miR-17 family, but it also suggested a number of unappreciated miRNA functions. Our results provide a significant resource for transcriptomic understanding of bovine miRNA regulation, and demonstrate the power of experimental methods for establishing comprehensive interaction maps.
