Research We Fund

The development of acute myeloid leukemia (AML) is preceded by a “preleukemic” phase in which mutated hematopoietic stem cells expand due to a fitness advantage. Our work uses prospective models and analysis of patient samples to study how the duration of preleukemia and how the preleukemic clonal burden affect progression to AML. Results of our studies will shed new light on AML pathogenesis and help guide clinical management of preleukemic conditions such as clonal hematopoiesis.

Most patients respond well to drugs that inhibit an important MCL target named BTK. However, almost all of them will eventually relapse and then do very poorly. Inhibition of MALT1, a target which is biochemically downstream of BTK, may rescue many of these patients, and inhibiting both BTK and MALT1 may be better still. Developing a drug that inhibits both targets at the same time, from the beginning of treatment, will avoid some complications and likely be best of all; we will find out.

Our research program’s goal is to identify therapeutically actionable pathways in pre-leukemic and leukemic stem cells in myeloid malignancies. We specifically dissect molecular circuits governing stem cell self-renewal and differentiation, how these change during aging, and contribute to leukemic stem cell evolution and maintenance. Accomplishing this work will enable the rational design of curative intervention and perhaps even prevention strategies for patients with myeloid malignancies.

The goal of this project is to investigate the role of the epigenetic regulator Eleven-Nineteen-Leukemia (ENL) and its cancer mutations in acute myeloid leukemia (AML). Our studies leverage the expertise in chromatin biology, functional genomics, and AML modeling, as well as unique chemical compounds and mouse models. Results from this project will provide novel biological insights into our understanding of AML pathogenesis and facilitate the development of novel epigenetic therapies.
