RESEARCH SUMMARY

The balance between maintaining stem cells and their more differentiated progeny is critical for the development and function of most tissues. Understanding how stem cells self-renew and commit to specific cell lineages remains a central question in stem cell biology. The laboratory is currently focused on understanding the cellular and molecular regulation of hematopoietic stem cell (HSC) quiescence, survival, self-renewal, and cell fate. These processes are regulated, in part, by transcription factors and epigenetic regulators recruited to DNA, which modify histones, DNA, and other proteins to activate or repress gene expression. The laboratory is currently defining the physiological function of the inhibitor of DNA binding (Id) family of proteins in self-renewal, quiescence and cell fate determination. Since transcription factors and epigenetic regulators are frequently deregulated in hematopoietic malignancies, it is anticipated that these studies will lead to the development of novel therapeutic agents.
