Abstract Background Hepatitis C virus HCV associated liver diseases may be related to apoptotic processes. Thus we investigated the role of different HCV proteins in apoptosis induction as well as their potency to interact with different apoptosis inducing agents. Methods and Results The use of a tightly adjustable tetracycline Tet -dependent HCV protein expression cell system with the founder osteosarcoma cell line U-2 OS allowed switch-off and on of the endogenous production of HCV proteins. Analyzed were cell lines expressing the HCV polyprotein the core protein protein complexes of the core envelope proteins El E2 and p7 and non-structural proteins NS3 and NS4A NS4B or NS5A and NS5B. Apoptosis was measured mainly by the detection of hypodiploid .
