Mutations point the way to new leukemia drugs

...ds the bone marrow to make it dense and stiff, and forces blood formation to shift to the spleen and liver. Eventually those two organs become grossly enlarged; the end result is death. Thus, the JAK2 pathway is an important player in leukemia. Levine, Pikman, and Gilliland's new work shows that the pathw...
