The laboratory utilizes multidisciplinary approaches to understand how mammalian cells choose specific fates and how mutations in important transcriptional regulators lead to developmental defects or malignancy. Recent and ongoing work falls into several overlapping areas. First, while many of the essential hematopoietic transcription factors are identified, how they act in the context of other factors within progenitors is less well understood. Hence, we are using biochemical and molecular approaches to address the function of these factors. Second, we are exploring the role of epigenetic modifiers in the biology of hematopoietic stem cells (HSCs), individual hematopoietic lineages, and pluripotent ES cells. Third, we studying the pathogenesis of leukemia and one solid tumor, osteosarcoma, using engineered mice and genomic methods. These studies include modeling one form of infant leukemia in iPS cells. Finally, we have defined the transcription factors critical to developmental regulation of the human globin genes, and are pursuing approaches to the reactivation of the fetal globin genes in adults as a means of therapy for the frequent hemoglobin disorders, sickle cell anemia and beta-thalassemia. Many of the studies in the laboratory have recently employed genetic and chemical screens using complex libraries.
