Project description:The experiment investigates bovine gene expression in response to BW720c treatment in uninfected and Theileria annulata-infected cell cultures Theileria annulata, an intracellular parasite of bovine lymphoid cells, induces substantial phenotypic alterations to its host cell including continuous proliferation, cytoskeletal changes and resistance to apoptosis. While parasite induced modulation of host cell signal transduction pathways and NFκB activation are established, there remains considerable speculation on the complexities of the parasite directed control mechanisms that govern these radical changes to the host cell. Our objectives in this study were to provide a comprehensive analysis of the global changes to host cell gene expression with emphasis on those that result from direct intervention by the parasite. By using comparative microarray analysis of an uninfected bovine cell line and its Theileria infected counterpart, in conjunction with use of the specific parasitacidal agent, buparvaquone, we have identified a large number of host cell gene expression changes that result from parasite infection. Our results indicate that the viable parasite can irreversibly modify the transformed phenotype of a bovine cell line. 50% of genes with altered expression failed to show a reversible response to parasite death, a possible contributing factor to initiation of host cell apoptosis. The genes that did show an early predicted response to loss of parasite viability highlighted a sub-group of genes that are likely to be under direct control by parasite infection. Network and pathway analysis demonstrated that this sub-group is significantly enriched for genes involved in regulation of expression and chromatin modification. The results provide evidence that the Theileria parasite has the regulatory capacity to generate widespread change to host cell gene expression in a complex and reversible manner.

Project description:Investigation of parasite (T. annulata) gene expression over the course of the life-cycle (sporozoite->macroschizont->merozoite->piroplasm). The study focused on the expression of known and putative transcription factors, in particular members of the ApiAP2 gene family. Up-stream motifs associated with stage-specifically expressed genes were identified during the course of the analysis.

Project description:The experiment investigates bovine gene expression in response to LPS in uninfected and Theileria annulata-infected cell cultures A subset of genes are identified which are activated in response to LPS stimulation with further modulation due to parasite infection. Six experimental conditions with three replicates per condition. Total RNA prepared from cell cultures. BL20 (uninfected bovine lymphosarcoma cell line), BL20 4 hours post-LPS stimulation, BL20 18 hours post-LPS, TBL (T. annulata infected bovine cell line), TBL 4 hours post-LPS, TBL 18 hours post-LPS. Each hydridisation represents bovine and parasite gene expression on a single channel and 2 technical replicates of each probeset are represented on the chip.
