Targeting STAT5 in hematopoietic cancers

T cell acute lymphoblastic leukemia (T-ALL) is an aggressive immature T cell cancer. A research team led by Prof. Richard Moriggl at the University of Veterinary Medicine Vienna has studied the most frequent and clinically challenging STAT5BN642H driver in T cell development and immature T cell cancer onset in genetically modified mice. Supported by SFB groups and highly regarded international collaborators the first author Tobias Suske found small molecular agents targeting STAT5B drastically reduced cancer growth in human T-ALL cell lines grafted into mice.
