mechanisms of progression and relapse in Acute Lymphoblastic LeukemiA

Acute Lymphoblastic Leukemia (ALL) is an aggressive malignancy of thymocytes that affects thousands of children and adults in the United States each year. Recent advancements in conventional chemotherapies have improved the five-year survival rate of patients with ALL. However, patients with relapse disease are largely unresponsive to additional therapy and have a poor prognosis. Utilizing zebrafish models of relapsed T- and B-ALL, we have uncovered oncogenic drivers associated with aggression, therapy resistance and relapse. These pathways are also important regulating human leukemia progression and response to therapy.  Discovering novel relapse-driving oncogenic pathways will likely identify new drug targets for the treatment of a wide array of leukemia subtypes.
