Utilizing the Tumor's Appetite for Sugar

A team from the Technical University of Munich (TUM) has decoded the factor that makes T cell lymphomas grow comparatively rapidly: A missing "emergency shut-off switch" results in the lymphomas processing particularly large amounts of sugar and triggers other processes as well. Medications for other types of cancer can stop this process, causing the tumor cells to die off. The process is to be verified in clinical studies in the near future.

T cell lymphomas are a subgroup of tumors which are especially aggressive and difficult to treat, in part because much remains as yet unknown about the molecular processes involved in this type of cancer. A team led by Prof. Jürgen Ruland, director of TUM’s  Institute for Clinical Chemistry and Pathobiochemistry and Principal Investigator at TranslaTUM, the TUM Central Institute for Translational Cancer Research and Prof. Jaehyuk Choi of Northwestern University in Chicago have successfully answered important questions and formulated new treatment strategies.

The lymphomas arise through genetic changes in certain immune cells, referred to as T cells, which then lose their function, reproduce in great quantities and form tumors at various locations in the body. In a previous study in "Nature", Ruland's team was able to prove that a particular gene had changed in approximately one third of the T cell lymphomas. This gene contains the "blueprints" for the protein PD-1. PD-1 normally functions as a sort of emergency shut-off switch: Referred to as a tumor suppressor, it prevents the mutated cells from reproducing and resulting in cancer.
