Previous studies of genes associated with retroviral-induced neoplasia have provided the foundation for much of our current knowledge of both tumor suppressor and oncogenes, and have contributed to our understanding of both gene function and malignant transformation. The study of Friend virus-induced erythroleukemia, a well-studied example of multistage malignancy, has led to the identification of several oncogenes, including the Ets transcription factor, fli-1. Fli-1 plays a vital role in hematopoiesis, and vasculogenesis through the transcriptional regulation of its target genes, some of which are critical for the control of cellular proliferation, differentiation, and survival. The aberrant regulation of Fli-1 is associated with a number of cancers and human diseases, including erythroleukemia, Ewing’s sarcoma, lupus, and Jacobsen or Paris Trousseau syndrome. The essential goal set out to be achieved by the research presented herein is to establish a better understanding of both the oncogenic and developmental roles of Fli-1 by investigating the molecular basis by which its deregulated expression leads to fundamental aberration in the fine balance between proliferation and differentiation.
