Genetic Instability and Resistance

Exploiting the IGF pathway for the treatment of Osteosarcoma and brain tumors

The insulin-like growth factor (IGF) pathway has long been recognised as a major molecular target in pediatric tumors. However, clinical studies of IGF-1 receptor (IGF-1R)-targeted monotherapies have been largely disappointing and no inhibitors have been released to date. Our hypothesis is that the crosstalk between the IGF pathway and other tyrosine kinases receptors (RTKs) can influence the efficacy of the IGF inhibition. We are therefore interested in the identification of interaction partners of IGF1-R, particularly in osteosarcoma (OS) and brain tumors. As functional model we are using primary tumor cells of OS patients. The cells are used for a pharmacological screening with IGF inhibitors to identify the best drug combination at the individual level.
