Mathias Rosenfeldt: Tumor metabolism and autophagy


The main focus of our group is to understand how and why cancer cells develop specific dependencies on certain metabolic processes to sustain survival and growth.  We study metabolic networks and how they are interconnected with each other in order to identify critical tumor specific liabilities that can be targeted for therapy. One process that potentially can be successfully exploited for cancer treatment is autophagy, a cellular self-digestion process that is tightly interwoven with cellular metabolism. Current work aims to unravel the unknown but essential metabolic functions of autophagy in cancer.
