New insights and pioneering work in targeted therapy against blood cancer

Research by Prof. Richard Moriggl and his team at the University of Veterinary Medicine, Vienna and the Paris Lodron University of Salzburg has provided new insights into the development and possible treatment of T-cell acute lymphoblastic leukemia (T-ALL). They discovered that the protein STAT5B, which is activated by mutations in T-ALL patients, promotes cancer growth by stimulating cell division. This finding could lead to new targeted therapies. Pilot experiments in mice have shown that drugs that target STAT5B or inhibit a target protein of it can reduce cancer growth. Such an agent targeting ZAP70 has already been approved for other diseases and could therefore be rapidly tested in clinical trials for T-ALL. The results could also be relevant for other T-cell leukemias and require further research and clinical trials.
