The GM-CSF receptor belongs to the cytokine receptor superfamily. The high-affinity receptors of this class are lacking intrinsic tyrosine kinase domains. The GM-CSF receptor consists of alpha and beta subunits. The beta subunit is shared with the receptors of IL-3 and IL-5. In addition to the membrane bound forms the receptors have been found to possess soluble isoforms. Since retroviral infection of the human GM-CSF dependent cell line, TF-1, leads to factor independent growth by increased expression of the GM-CSF receptor alpha chain in a subgroup of infected clones, we were interested in studying the role of this chain in human AML. Further considering that a point mutation in the extracellular domain of the erythropoietin receptor, also a member of the cytokine receptor superfamily, resulted in constitutive activation of a murine cell line, we investigated the possibility that a point mutation of the GM-CSF receptor was responsible for autonomous growth of AML cells. We sequenced a segment of the receptor coding for the extracellular domain of the alpha subunit. cDNA was prepared from peripheral blood or bone marrow cells from 24 patients with AML, from four patients with MDS and from three human myeloid cell lines. The region of interest was amplified with two rounds of PCR reactions with nested primers, covering five overlapping fragments, and directly sequenced using a non-radioactive technique. No point mutations were found in the investigated samples. Thus, point mutations in this segment of the GM-CSF receptor gene do not seem to play an important role in the transformation process of human acute leukemia.
