The macrophage colony-stimulating factor receptor is encoded by the c-FMS gene, and it has been suggested that altered regulation of c-FMS expression may contribute to leukaemic transformation. c-FMS is expressed in pluripotent haemopoietic precursor cells and is subsequently upregulated during monocytic differentiation, but downregulated during granulopoiesis. We have examined transcription factor occupancy and aspects of chromatin structure of the critical c-FMS regulatory element located within the second intron (FIRE - fms intonic regulatory element) during normal and leukaemic myelopoiesis. Granulocytic differentiation from normal and leukaemic precursors is accompanied by loss of transcription factors at FIRE and downregulated c-FMS expression. The presence of AML1-ETO in leukaemic cells does not prevent this disassembly. In nonleukaemic cells, granulocytic differentiation is accompanied by reversal to a chromatin fine structure characteristic of c-FMS-nonexpressing cells. In addition, we show that low-level expression of the gene in leukaemic blast cells and granulocytes does not associate with increased CpG methylation across the c-FMS locus.
