Project A7

Regulation and function of the S100A8/S100A9 protein complex in inflammation-associated liver carcinogenesis

Principal Investigators: Prof. Dr. Peter Angel, PD. Dr. Jochen Heß

 

Short Summary

Enhanced levels of the pro-inflammatory proteins S100A8 and S100A9 are hallmarks of chronic inflammation and epithelial cancer. Recently, we found increased S100A8/A9 expression during malignant progression of mouse and human liver carcinogenesis and provided experimental evidence that they activate ROS-dependent signaling and protect hepatocellular tumor cells from apoptosis. The goal of our proposed project is the establishment of pre-clinical mouse model systems for translational cancer research and the development of strategies to target components of S100A8/A9-induced signaling pathways and genetic networks as novel therapeutic option.
