In contrast, control mice coexpressing with TEL-PDGFRB and a DNA-binding-mutant of AE developed a nontransplantable myeloproliferative disease identical to that induced by TEL-PDGFRB alone.
Myeloproliferative neoplasms associated with FIP1L1-PDGFR rearrangements represent a rare subset of myeloid and lymphoid malignancies, characterised by the presence of eosinophilia and abnormalities of PDGFRA, PDGFRB or FGFR1 genes.
Fusion of PRKG2 and SPTBN1 to the platelet-derived growth factor receptor beta gene (PDGFRB) in imatinib-responsive atypical myeloproliferative disorders.
Therapeutically validated oncoproteins in myeloproliferative neoplasms (MPNs) include BCR-ABL in chronic myelogenous leukemia (CML) and a spectrum of PDGFRA/B mutant proteins that are products of intra- (eg, FIP1L1-PDGFRA) or interchromosomal (eg, ETV6-PDGFRB) gene fusions.
