1) It has been known for more than one hundred years that there is a link between chronic inflammation and cancer development. Inflammatory bowel disease, especially ulcerative colitis is a risk factor for development of colorectal cancer. Chronic liver damage and liver cirrhosis caused by viral hepatitis B and C or alcoholic or non-alcoholic steatoheptitis lead to development of hepatocelluar carcinoma (HCC). More than 50 percent of all hepatocellular carcinomas develop as a result of chronic tissue damage caused by chronic inflammation.
In our research group we use transgenic, knock-out and chemical induced cancer mouse models
- to develop new strategies for the treatment of liver cancer by inhibition of critical pathways by small molecule inhibitors, peptides, innovative viral vectors expressing shRNAs, combined targeting of cancer cells and tumor microenvironment, and improving tumor delivery of systemically administered drugs;
- to develop new magnetic resonance imaging imaging techniques (e. g. nanoparticle contrast agents) to detect and follow the growth of murine HCC;
- to elucidate critical regulators of inflammatory pathways for cancer development in the liver and the gut;
- to discover new biomarkers for HCC.
2) As the diagnosis of hepatocelluar carcinoma (HCC) in the cirrhotic liver is still a challenge and only early detection of cancer can result in effective treatment like resection or liver transplantation we aim to investigate and validate new biomarkers for early HCC detection. Moreover, we examine diagnostic and prognostic markers in patients with liver cirrhosis and HCC in patient material.
3) Gs protein-coupled receptors are known to signal via the second messenger 3'-5'-cyclic adenosine monophosphate (cAMP) regulates diverse cell functions, e. g. cell proliferation, differentiation, apoptosis, cell-cell and cell-matrix interaction and migration and immune function. Classical effectors of cAMP are protein kinase A (PKA) and Epac1 and Epac2 (Exchange factor directly activated by cAMP). We are currently investigating novel signaling mechanisms of cAMP, in particular the interaction of cAMP and purinergic signaling.
