Project description:The domestic ferret (ferret; Mustela putorius furo) is an important animal model for neuroscience and preclinical/veterinary medicine owing to its susceptibility to avian influenza and corona viruses. Nevertheless, there is a lack of in vitro ferret models, since immortal cell lines including induced pluripotent stem cells (iPSCs) of ferrets have been scarce. In this study, we established an induced pluripotent stem cell line from skin fibroblasts of a neonatal female ferret using a previously validated method in multiple mammalian species. The established line, fiPS-1, showed standard characteristics of pluripotency, but it showed an X chromosome instability characterized by the high emergence rate of aneuploid 39X cells from the original 40XX euploid cells.
Project description:The domestic ferret (Mustela putorius furo) has been used as animal model for decades, largely because its susceptibility to infection with a large number of pathogens such as influenza virus, SARS Corona virus and Canine distemper virus. Despite its importance for biomedical research, little is known about the genome of the M. Furo. The number of reagents for molecular and immunological analysis is thus restricted. To circumvent this, we present here a parallel sequencing effort to produce an extensive EST dataset derived from a normalized ferret cDNA library made from mRNA from ferret blood, liver, lung, spleen and brain. We produced more than 500000 sequence reads that were assembled into over 15000 partial ferret transcripts. These ESTs were combined with the available ferret sequences in the GenBank to develop a ferret specific microarray platform. Using this array, we detected tissue specific expression patterns which were confirmed by quantitative real time PCR assays and comparison to orthologous transcription profiles of mouse and human. We also present a set of 41 ferret transcript with even transcription profile across the tested tissues, indicating their usefulness as housekeeping genes. This study paves way for development of additional reagents for analysis of the ferret model. Three biological replicates of blood, lung, spleen, liver and brain was hybridized to the ferret specific microarray.
Project description:The domestic ferret has recently been described as a uniformly lethal model of infection for three species of Ebolavirus known to be pathogenic to humans. Reagents to systematically analyze the ferret host response to infection are lacking; however, the recent publication of a draft ferret genome has opened the potential for transcriptional analysis of ferret models of disease. In this work, we present comparative analysis of longitudinally sampled blood taken from ferrets and non-human primates infected with lethal doses of the Makona strain of Zaire ebolavirus. Strong induction of proinflammatory and prothrombotic signaling programs were present in both ferrets and non-human primates and both transcriptomes were similar to previously published datasets of fatal cases of human Ebola virus infection.

Project description:Brucella suis infects macrophages and dendritic cells. Wild boars act as reservoirs and carriers of Brucella suis biovar 2, and there is evidence that wild boar can be the main source of infection for domestic pigs through the venereal route. Transmission through this route could be an important path for disesease dissemination. The result from this study will contribute to the overall understanding of the molecular pathogenic mechanisms involved during Brucella suis infection in European wild boar.
