Project description:Microarrays were used to identify Y. pestis genes that are differentially regulated under conditions of phoP overexpression. RNA samples were isolated from cultures of two isogenic Y. pestis strains, one overexpressing phoP (KIM10+phoP(delta)/PhoP) and the other not (KIM10+phoP(delta)/MMB67EH), and their gene expression profiles were compared.
Project description:Microarrays were used to identify Y. pestis genes that are transcriptional targets of phoP. RNA samples were isolated from cultures of two isogenic Y. pestis strains, one carrying wild-type phoP (KIM6+) and the other carrying a deletion within phoP (KIM6+phoP(delta)), and their gene expression profiles were compared.
Project description:We used a mouse maternal separation model, a well-known paradigm of early adversity, to test the hypothesis that transcriptional changes in peripheral blood mononuclear cells (PBMCs) are paralleled by specific gene expression changes in three brain regions that are involved in the stress response. Furthermore, we evaluated whether gene expression profiles of PBMCs could be used to predict stress-related animal behaviours.

Project description:Effect of 5.4 ppm polycyclic aromatic hydrocarbons (PAHs) and 18.2 ppm alkylphenols (APs) on gene expression in adult Zebrafish (Danio rerio) liver after 1 and 7 weeks of water-borne exposure.
Project description:From two donors of human umbilical vein endothelial cells, in vitro cell lines were established. Both cell lines were grown in vitro until irreversible growth arrest was observed (replicative senescence). Total RNA from young (replicating) cells as well as senescent cells was harvested and used for hybridization of microRNA chips (MRC) from TU Graz based on Sanger miRBase 9.2
Project description:This experiment was carried out to see if there were any gene expression differences in pulmonary endothelial cells between patients with and without COPD. COPD is an inflammatory condition and although much work has previously been performed to investigate the inflammatory cells in COPD there has not been as much research looking at the endothelium through which inflammatory cells must pass through to reach the lung tissue. In this experiment pulmonary endothelial cells were extracted from whole lung tissue removed at the time of cardiothoracic surgery. This was performed for patients with and without COPD. RNA was extracted using the Qiagen micro RNeasy kits prior to transferring to the University of Birmingham Biosciences department who performed RNA labelling and ran the microarrays. Once the microarrays were performed quality was checked using ArrayQualityMetrics and the COPD group was compared to the non-COPD group using SAM. The experiment was then repeated using another patient group. Genes of interest were validated with qPCR initially before moving on to functional work.
