Regulation of Fli1 gene expression and lupus

Ets transcription factors function throughout development in such varied processes as cellular proliferation, apoptosis, differentiation and migration. Many have been implicated to play important roles in hematopoiesis, vasculogenesis/angiogenesis and myogenesis. Fli1 is an Ets family member that is essential for development and increasing evidence suggests modulating Fli1 gene expression impacts lymphocyte function and is important in the autoimmune disease lupus. Presently, it is unknown how Fli1 gene expression is controlled in lymphocytes. Identifying upstream regulators of Fli1 in lymphocytes will be critical for understanding lymphocyte development and the consequences of dysregulation and may be of value in developing future treatments for lupus.
