Virus-associated Carcinogenesis

Our Research

Our division –established in March 2014– aims at deciphering the basic principles underlying tumor formation in the context of chronic viral infection. Our research centers on liver cancer, which is one of the most frequent causes of cancer-related deaths. Around 75% of all liver cancer cases are linked to infection with hepatitis B virus (HBV), Hepatitis D virus (HDV) or hepatitis C virus (HCV). Thus, liver cancer is a paradigm for infection-associated tumors. The medical relevance is very high as reflected by the high numbers of persistently infected individuals: 240 million in case of HBV, an estimated 10-20% being co-infected with HDV, and around 70 million in case of HCV. These people have a high risk to develop serious liver damage, most notably liver cirrhosis and hepatocellular carcinoma. Important comorbidity factors are metabolic syndrome, alcohol consumption and chronic inflammation as induced and sustained by persistent virus infection. Since therapy of liver tumors still is very inefficient, there is an urgent need for preventive and therapeutic regimens as well as more sensitive diagnostics.

Together with our sister department “Molecular Virology” at University Hospital Heidelberg we already laid the ground to study the basic principles of the replication cycles of HBV, HDV, HCV and related viruses. In addition, given the similarities in important cell biology aspects, we have integrated studies focusing on the replication cycle of the severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) with the ultimate goal to develop broadly active antiviral drugs to increase future pandemic preparedness. Building on this expertise, within the division “Virus-Associated Carcinogenesis” at the German Cancer Research Center our research is centered on the following main topics:

The mechanisms how persistent hepatitis virus infections are established, how chronic infection contributes to the development of liver cancer and to devise novel concepts to break viral persistence, thus reducing the cancer risk
The basic principles how virus infections are sensed, how viruses overcome these antiviral strategies and the role of cell-intrinsic antiviral signaling in tumor development and therapy
The role of iron-regulatory networks in infection and inflammation-induced liver tumor Formation
The establishment of a portfolio of oncolytic parvoviruses and the analysis of virus-host cell interactions associated with virus-induced cell disturbances
