Project description:The transcriptomics changes induced in Primary Mouse Hepatocytes by Cyclosporin A after treatment for 24h and 48h The study investigated differential gene expression in Primary Mouse Hepatocytes mRNA following 24 and 48 hours of exposure to Cyclosporin A and solvent. Three biological replicates per compound/solvent. In total 24 arrays .
Project description:The microRNA changes induced in Primary Mouse Hepatocytes of C57Bl6-mice by Cyclosporin A after treatment for 24h and 48h The study investigated differential microRNA expression in Primary Mouse Hepatocytes following 24 and 48 hours of exposure to Cyclosporin A and solvent. Three biological replicates per compound/six per solvent. In total 24 arrays .
Project description:Drug-induced hepatotoxicity is a leading cause of attrition of candidate drugs in drug development. Therefore new screening methods are necessary which predict these hazards more accurate and earlier in the drug development process. Of all in vitro hepatotoxicity models, primary human hepatocytes are considered as 'the gold standard'. However, the use of these hepatocytes is hindered by their scarcity and major inter-individual variation. These limitations may be overcome with use of primary mouse hepatocytes. Within this context changes in protein expressions in primary mouse hepatocytes, after exposure to cyclosporin A were studied using differential gel electrophoresis. Thereafter, the mRNA expression levels of these deregulated proteins from cyclosporin A-treated cells were analyzed. Cyclosporin A induced ER stress and altered the ER-Golgi transport, which may alter vesicle mediated transport and protein secretion. Moreover are the differentially expressed proteins observed upon challenge by cyclosporin A, associated with cholestatic mechanisms. For each biological experiment, one hybridization was conducted and one sample per array. In total, 6 arrays were used for 2 different conditions (Csa or control at 48 hours).
