Project description:The aim of this study is to determine differential gene expression on skin biopsies of experimentally BTV-infected hinds (Cervus elaphus) using serotypes 1 and 8 to understand the possible role that these genes play during BTV infection. Understanding the strategies used by this virus for their cellular uptake, and detection of differentially expressed transcripts in experimentally infected hosts, can provide identification of detailed information that might be used to prevent infection. Four seven-month-old red deer Cervus elaphus were kept in a P3 facility to be experimentally infected with Bluetongue virus, and 4 more red deer were kept as controls. Skin biopsies were taken at 14 days post-infection to determine gene expression in response to this virus.

Project description:We present the analysis of an osseous finger ring from an early Neolithic context in Denmark. To characterise the artefact and identify the raw material used for its manufacture, we performed micro-computed tomography (Micro CT) scanning, zooarchaeology by mass spectrometry (ZooMS) peptide mass fingerprinting, as well as protein sequencing by liquid chromatography tandem mass spectrometry (LC-MS/MS). We found that the ring was made from long bone or antler due to the presence of osteons (Haversian canals). Subsequent ZooMS analysis of the collagen present indicated that it was made from either elk (Alces alces) or red deer (Cervus elaphus) material. We then used LC-MS/MS analysis to refine our species identification, confirming that the ring was made from red deer, and to examine other proteins present. This study demonstrates the potential of ancient proteomics for species identification of prehistoric artefacts made from osseous material.

Project description:Rib bone growth in red deer stags - Abstract: In 'The Bone and Joint Decade' interest is focused on genetic factors causing bone disorders. Osteoporosis, attacking 10% of the population worldwide, is the most common metabolic bone disease, which is mimiced by several ovarectomised or genetically modified 'cascadeur' animal species, but none of them is able to remedy its pathologically porous bone tissue. Regeneration in skeletal elements is the curiosity of our newly investigated osteoporosis animal model, red deer (Cervus elaphus). The cyclic physiological osteoporosis in red deer stag is a consequence of the annual antler cycle. This phenomenon raises the possibility to explore new genes involved in regulating bone mineral density (BMD) and recovery of bone resorption on the basis of comparative genomics between deer and human. Here we compared the gene expression activities of osteoporotic and regenerating flying rib bone samples versus late autumn dwell control in red deer by heterologous microarray hybridization. Identified genes were tested on human femoral bone tissue from postmenopausal osteoporotic and non-osteoporotic patients. Expression data were evaluated by Principal Components Analysis and Discriminant Analysis. Keywords: Gene Expression experiment

Project description:Anaplasma and Mycobacterium species are known to modify gene expression in ruminants. The objectives of this study were (a) to characterize global gene expression profiles in European red deer (Cervus elaphus) in response to Anaplasma ovis and A. ovis/Mycobacterium bovis/M. avium sub. paratuberculosis (MAP) infections, (b) to compare the expression of immune response genes between A. ovis- and A. ovis/M. bovis/MAP-infected deer, and (c) to characterize the differential expression of immune response genes identified in red deer in cattle infected with M. bovis and A. marginale. The results of this study showed that global gene differential expression in A. ovis- and A. ovis/M. bovis/MAP-infected deer results in the modification of common and pathogen-specific cellular biological processes. The differential expression of host immune response genes also showed pathogen-specific signatures and the effect of infection with multiple pathogens on red deer host immune response. These results suggested that intracellular bacteria from Anaplasma and Mycobacterium genera use similar mechanisms to infect and multiply within ruminant host cells while pathogen-specific mechanisms underline differences that could contribute to disease characterization and diagnosis in ruminants.

Keywords: Gene Expression experiment Approximately 2-3 g flying rib bone pieces in the entire cross section of bony rib were surgically removed from 3 anaesthetized [SBH-Ketamine (2.5 mg/kg live weight) combined with Xylazine (0.2 mg/kg live weight) i.m. injection] 6, 7 and 8 year old Cervus elaphus stags. (Cast antler pairs weighed 7-8 kg for each animal.) Removed rib pieces were extensively washed in PBS for eliminating blood and marrow contamination, than immediately frozen in liquid nitrogen. The time of tissue collections were (i) within the period of the active mineralization of antler, at the beginning of June when skeletal osteoporosis takes place, (ii) in the fitness improvement period with velvet shedding in late July, that is the 'regenerating time' and (iii) in the period of late autumn dwell at the end of November when in the skeleton the mineral mobilization and deposition are dynamically equilibrated (BMD is in steady state). Each comparison performed on Platforms GPL4052 and GPL5352.

Project description:Bovine tuberculosis (bTB), caused by Mycobacterium bovis (Mycobacterium tuberculosis complex), is a zoonotic disease that affects cattle and wildlife worldwide. In some regions of Spain, Iberian red deer (Cervus elaphus hispanicus) can serve as reservoir of infection, thus increasing the risk of human and cattle exposure and infection. Mesenteric lymph nodes are naturally infected with M. bovis in Iberian red deer, in which the digestive route of infection is particularly important in Mediterranean Spain. In this study we characterized the differential expression of inflammatory and immune response genes in mesenteric lymph nodes of Iberian red deer naturally infected with M. bovis using a Ruminant Immuno-inflammatory Gene Universal Array (RIGUA) and real-time RT-PCR. Of the 600 genes that were analyzed in the microarray, 157 showed ? 1.2 fold changes in expression in infected or uninfected deer and 17 genes displayed an expression fold change greater than 1.7 with a P-value ? 0.05 and were selected for further analysis. These genes included tight junction proteins (Z02 and occluding), IL-11R, bactenecin, CD62L, CD74, desmoglein, IgA and IgM that constitute new findings and suggest new mechanisms by which M. bovis may modulate host inflammatory and immune responses. Identification of genes differentially expressed in animals and tissues naturally infected with M. bovis contributes to our basic understanding of the mechanisms of pathogenesis and protective immunity to mycobacterial infections and may have important implications for future functional genomic and vaccine studies to aid in the control of bTB in deer and other wildlife reservoir species. Mesenteric lymph node RNA from four different uninfected Iberian red deer stags and two Iberian red deer stags infected with Mycobacterium bovis. Infected animals were naturally infected with M. bovis. All animals were hunter-harvested and the tissues retrieved 2-6 hrs after animal hunting.
