Acute myeloid leukemia (AML) is the most common type of leukemia in adults with approximately 20,000 new cases and 10,000 deaths each year in the United States. Despite considerable improvement of survival rates for patients with leukemia over the past 50 years, the overall five-year relative survival rate for AML patients is only approximately 20 percent.
Leukemia stem cells (LSCs) are now recognized as the critical “seeds” of leukemia, and represent a fundamental challenge thought to underlie poor outcome due to their relative resistance to standard chemotherapy. Our long-term goal is to elucidate the molecular mechanism(s) regulating the maintenance of LSCs, to understand how they differ from normal hematopoietic stem cells, and to develop novel LSC-targeted therapeutics. Using a genetic mouse model of a common chromosome aberration found in AML patients, known as inv(16), we have shown that leukemia arises as a result of a multi-step transformation process involving mutations that disrupt hematopoietic differentiation, and those that deregulate proliferation and self-renewal programs.
Our current research efforts are directed towards understanding the molecular pathways and functional mediators regulating normal hematopoiesis as well as those underlying leukemogenesis using a combination of genetics, genomics, biochemistry, proteomics, molecular biology and cellular biology approaches. We use defined genetic mouse models as an experimental system to identify molecular pathways and targets, and primary cells from AML patients to validate the findings and perform further translational and preclinical studies. We believe that a comprehensive understanding of oncogenic mechanisms will enable rational design and selection of improved cancer treatments.
