Acute myeloid leukemia (AML) is the deadliest blood cancer. People with AML are treated with chemotherapy, a treatment intended to kill cancer cells. However, some AML cells have qualities that prevent them from being killed with chemotherapy. These cells remain in the body even after treatment. Unfortunately, these “chemotherapy-resistant” AML cells can cause relapse. People with AML achieve remission when doctors can no longer detect AML after treatment. Relapse occurs when the previously undetectable AML returns after remission. Relapse is the primary cause of death for AML patients. Unfortunately, ~30% of all AML patients will relapse within three years of their diagnosis. Our research goal is to understand why some AML cells survive chemotherapy and others do not. We aim to identify new treatments that target chemotherapy-resistant AML cells.

Certain proteins produced by many cells in the body have sugars attached to them. In AML cells, we found that the kind of sugar attached to these proteins determines growth rates and response to chemotherapy. In this proposal, we will test how specific categories of sugars control AML cell growth, chemotherapy resistance, and relapse. We will use mouse models of AML to test how drugs that change the sugars available to AML cells could be used to treat AML. We expect the proposed studies will pave the way for identifying new medicines that can be used to stop AML cells from resisting chemotherapy, prevent relapse, and support AML patient survival.
