Potential Rotation Projects
1. Role of core binding factors on hematopoietic stem cell function and survival. We use molecular pharmacologic and functional approaches to study the role of the RUNX factors in self renewal and proliferation of hematopoietic stem and progenitor cells, using genetically modified mice and human progenitor cells.
2. Study the molecular mechanism of leukemia initiation and maintenance. Transcription factors and components of cytokine signaling are frequently mutated in human cancer, including leukemia. These mutations deregulate the proliferation, differentiation and survival of hematopoietic stem cells. We study the role of members of RUNX and RAS protein families in the function of hematopoietic stem cell function, pre-leukemic progenitors, and leukemia-initiating cells.
3. Translational research: Recent evidence suggests that inhibition of pathways activated by gene mutations can be used to eliminate leukemia cells, and not affecting normal cells. We use small molecule inhibitors of leukemia oncogenes to test whether repression of activated pathways hinder survival of leukemia initiating cells, and eliminate leukemia. We use a combination of mouse models and human leukemia cells to test the efficacy, specificity and toxicity of candidate inhibitors, as single agents or in combination with first line leukemia drugs.
