Project description:Our aim was to study the gene expression changes associated to the development of non hepatic steatohepatitis from simple steatosis in a model of diet induced obesity in hamster (mesocricetus auratus)
Project description:To investigate the relationship between the expression of the UPR (unfolded protein response) genes, and the SARS-CoV-2 infection, a study was carried out based on the infection of hamster, Mesocricetus auratus. UPR gene levels were compared between infected and uninfected hamsters at different temporal points.
Project description:COVID-19 or severe acute respiratory syndrome coronavirus 2 (SARS-CoV-2), appeared first in Wuhan, Hubei, China, has emerged as a global health concern claiming millions of lives worldwide. Syrian golden hamster (Mesocricetus auratus) has emerged as a suitable model as when infected by SARS-CoV-2, manifests lung pathology resembling human COVID-19 patients. In this study, we employed a quantitative approach to study the proteomic changes in the SARS-CoV-2-infected lung tissue. The samples were analyzed using Orbitrap Fusion Tribrid mass spectrometer in triplicates and the data acquired was searched against Mesocricetus auratus protein database which resulted in the identification of nearly 2,000 non-redundant proteins. The outcome of this study will facilitate in discovery of potential candidate biomarkers for predicting disease course and warrants their further validation in human patient samples.
Project description:Cholesteryl ester transfer protein (CETP) transfers cholesteryl ester (CE) and triglyceride (TG) between lipoproteins, which alters lipoprotein metabolism. Hamster and human CETPs have very different preferences for CE versus TG as substrate. To assess the impact of altering CETP’s substrate preference on lipoproteins in vivo, human CETP was expressed in hamsters (Mesocricetus auratus). Chow-fed hamsters received adenoviruses expressing no CETP (Ad-Null), hamster CETP (Ad-hamster CETP) or human CETP (Ad-human CETP). High density lipoproteins were isolated from hamster plasma 6 days after adenovirus injection by ultracentrifugation as the 1.063 - 1.21 g/ml density fraction. HDL proteins were precipitated with cold acetone and subjected to LC+MS/MS analysis
Project description:We report the application of bulk RNA sequencing technology for high-throughput profiling of SARS-CoV-2 infection in the lung of Syrian golden hamsters (Mesocricetus auratus).
