A retroviral library genetic screen identifies IRF-2 as an inhibitor of N-ras-induced growth suppression in leukemic cells.

Abstract excerpt

Activating mutations of the N-ras gene occur at relatively high frequency in acute myeloid leukemia and myelodysplastic syndrome. Somewhat paradoxically, ectopic expression of activated N-ras in primary hematopoietic cells and myeloid cell lines (in some cases) can lead to inhibition of proliferation. Expression of mutant N-ras in murine hematopoietic stem/progenitor cells is sufficient to induce myeloid...
