overcome cell death resistance in gastrointestinal cancer.

NCT AG Cell Death Resistance

 

Our group/department has:

  • started to investigate the role of anaerobic tumor cell growth for therapy resistance and clinical course in colorectal carcinoma (Deutsche Krebshilfe-funded project)
  • has for the first time demonstrated that non-canonical NFκB and its master transcription factor RelB drives liver fibrosis and hepatocarcinogenesis (DFG-funded project, Elßner et al. Gastroenterology 2019)
  • has been part of the Heidelberg Clinical Research Unit KFO 227 on Colorectal Cancer with a subproject addressing the role of anti-apoptotic Bcl-2 proteins for colorectal cancer development and progression. In the context of the KFO 227, the group i) has established various, intestine-specific Bcl-2 protein knockout mouse models unravelling novel functions of antiapoptotic Bcl-2 proteins (Scherr et al. Cell Death Diss 2016, Radakrishnan et al. Cancer Res. 2016) ii) has shown that suppression of anti-apoptotic Bcl-2 proteins regulates migration and invasion of colorectal cancer cells independent of cell death induction (Köhler et al. PLOS One 2014, PLOS One 2013)
  • proved that downregulation of the deubiquitinase CYLD i) contributes to apoptosis resistance of HCC cells (Urbanik et al. Int J Oncol 2011) and ii) triggers NF-kB activation and hepatocarcinogenesis in mice in vivo (Urbanik et al. J Hepatol 2012)
  • has demonstrated that increased apoptosis of hepatocytes coincides with strong hepatocyte proliferation resulting in spontaneous development of hepatocellular carcinoma in mice (DFG-funded project, Weber et al. Hepatology 2010).
  • has been associated to the largest European research consortium on HCC (SFB/TRR77 Heidelberg/Hannover) in 2010 with its project addressing the role of the anti-apoptotic Bcl-2 protein Mcl-1 for the pathophysiology of liver diseases (Vick et al. Hepatology 2009).
