Zebrafish may point the way toward genes responsible for T cell leukemia

Scientists hunting for genes responsible for acute lymphoblastic leukemia have a new compass: a system that uses powerful genetic techniques in a zebrafish model. Researchers report they have created a zebrafish model that will help scientists pinpoint genes that accelerate or delay the spread of T cell acute lymphoblastic leukemia (ALL), a disease responsible for 400 deaths – about half of them, children – in the United States each year. The model may also provide a faster, more direct way of testing novel drugs against the disease.
