Job description:

Project: Targeting MYC-driven pediatric brain tumors

MYC family members are among the most deregulated proto-oncogenes in pediatric brain tumors, giving rise to different brain tumor entities, including medulloblastoma (MB) and glioblastoma (GBM). The central role of MYC, the highly aggressive nature of these MYC-deregulated brain tumors, the extremely poor outcome of the patients, and the low direct druggability of MYC creates a huge clinical challenge and urgent need to develop better strategies for targeting these MYC-driven brain tumors. The aim of this project, which is part of a larger DKTK- and DKH-funded program with other groups in and outside the DKFZ targeting MYC-driven cancers, is to develop new treatment strategies for these MYC-driven pediatric brain tumors. We will use sophisticated pre-clinical models including orthotopically transplanted patient-derived xenografts (PDX) and organoid cultures. Many PDX models from MYC-driven MB and GBM have already been established and molecularly characterized, but many more are needed to fully represent the patient population. Organoid cultures are being established in collaboration with Hans Clevers in the Netherlands. We will use these models (a) for hypothesis-driven targeted treatment approaches in vitro and in vivo, and (b) for large scale synthetic lethal screens using CRISPR/shRNA or drug libraries (collaboration with Claudia Scholl and Michael Boutros at the DKFZ) to identify novel drug targets in these MYC-driven brain tumors.
