Further Information

Research group(s)

Research interests

  • Basic biomedical science to identify functions of transcription factors in diseases
  • Development of transgenic mouse models for cooperative mutations in cancer development
  • Investigation of molecular and cellular processes in the tumor microenvironment that influence cancer formation with a focus on tumor-associated macrophages and STAT3
  • Cytokine signaling in cholestatic liver fibrosis, hepatocellular carcinomas and formation of colorectal tumors with a focus on transcription factors STAT1 and STAT3

Techniques, methods & infrastructure

  • Generation of transgenic, knockout and knockin mice
  • Mouse models with conditional deletion of STAT1, STAT3 or CDHR5 in intestinal epithelial cells, hepatocytes, macrophages and fibroblasts
  • Mouse tumor models for colorectal cancer, intestinal cancer and liver cancer (hepatocellular carcinoma)
  • Preparation of swiss roles and mouse tumor analysis
  • Quantitative histomorphometry of IHC (immunohistochemical) stainings and immunofluorescence with Definiens software
  • Quantitation of tumor vessel parameters (wall thickness, lumen, vessel numbers, vessel size)
  • Characterization of immune cell infiltrates in tumors using immunohistochemistry and FACS
