Fibroblast and hematopoietic cell transformation by the fms oncogene (CSF-1 receptor).

The c-fms proto-oncogene encodes the receptor for the mononuclear phagocyte colony stimulating factor, CSF-1. Although the tyrosine kinase activity of the CSF-1 receptor is stimulated by its ligand, the viral oncogene, v-fms, encodes a constitutive receptor kinase that can transform both fibroblasts and hematopoietic cells by a nonautocrine mechanism. Mutations in the c-fms gene as well as a critical alteration of the distal 3' coding sequences appear to be responsible for fully activating its latent transforming potential. The v-fms gene can convert CSF-1 or IL-3 dependent hematopoietic cell lines to factor independence and render them tumorigenic. Expression of the v-fms gene product does not transmodulate the normal receptors for CSF-1 or IL-3 and affects neither their affinity, number, nor potential to be independently down-regulated by their ligands or by phorbol esters. The ability of v-fms to transform hematopoietic target cells suggests that critical alterations in the c-fms proto-oncogene might similarly contribute to leukemia.[1]
