  • Genetic control and manipulation of normal and malignant hemopoiesis
  • Stem cell regulation, retroviral gene transfer, transgenic mice

My research concentrates on two major areas. The first is the characterization of genes that underlie the self-renewal and multipotential differentiation capacity of hemopoietic stem cells. The former property is essential for the life long maintenance of hemopoietic function and for regeneration after damage or transplantation; the latter results in the production of the multiple specialized but short lived mature blood cell types.

Most recently, we have focused on the Hox homeobox family of transcription factors as candidate intrinsic regulators of normal primitive hematopoietic cell properties and as participants in leukemic transformation. Expression profiling has documented differential expression of Hox genes in primitive hematopoietic subpopulations and retroviral gene transfer has been used to engineer the overexpression of Hox genes with observed marked effects on hemopoiesis in mouse transplantation and embryonic stem cell models. These studies have revealed remarkable Hox gene specific effects ranging from the ability of HOXB4 to markedly enhance stem cell self-renewal to a leukemogenic activity of other Hox genes. These findings implicate Hox genes and likely upstream regulators of Hox gene expression, downstream targets of Hox genes and interacting proteins in the regulation of normal stem cell self-renewal/differentiation and in leukemic transformation. Work now is directed at better understanding this regulatory gene network in both murine and human hematopoietic cells. This includes further functional studies using genetic engineering in bone marrow, transgenic animals and embryonic stem cells; expression profiling to identify possible target genes; and yeast-2 hybrid analyses to identify novel interacting proteins.

The second major line of investigation is directed towards the development of improved gene transfer methods to primitive hematopoietic stem cells with the goal of improving approaches for gene function studies and gene therapy. This work includes a major emphasis on developing strategies for gene therapy of inherited anemias such as Thalassemia and sickle cell disease. This work includes testing of a variety of novel retro- and lentiviral based vectors carrying potentially therapeutic genes in a variety of in vitro and in vivo models - the latter including transgenic mice that mimic human Thalassemia or sickle cell disease. Novel approaches for non-viral mediated gene transfer to hemopoietic cells are also being explored by utilizing cre/lox recombination methodology.
