The research was published online on September 20 in the Journal of Experimental Medicine.

Paul-Henri Romeo and colleagues find that TAL1, a protein abundantly expressed in approximately 40% of patients with T cell acute lymphoblastic leukemia (T-ALL), drives expression of NKX3.1. Eliminating NKX3.1 halted the growth of TAL1-expressing T-ALL cells in culture and after injection into mice.

It's not yet clear how NKX3.1 sustains the growth of T-ALL cells, but these findings show that this protein can either halt or hasten tumor development depending on the tissue environment.
