It is well-known that isolation and cultivation of primary hepatocytes causes major gene expression alterations. In the present genome-wide, time resolved study of cultivated human and mouse hepatocytes, we made the observation that expression changes in culture strongly resemble alterations in live...
Prion protein (PrP) concentration controls the kinetics of prion replication and is a genetically and pharmacologically validated therapeutic target for prion disease. In order to evaluate PrP concentration as a pharmacodynamic biomarker and assess its contribution to known prion disease risk factor...
