Popis: Primary myelofibrosis (PMF) is a myeloproliferative neoplasm characterised by the clonal proliferation of the haematopoietic precursors together with the progressive development of bone marrow fibrosis. This stromal alteration is an important clinical issue and specific prognostic markers are not currently available. In bone marrow biopsies from 58 PMF patients, we explored the methylation pattern of genes encoding cytokines involved in the stromal reaction, namely platelet-derived growth factor-beta (PDGFB), transforming growth factor-beta (TGFB) and basic fibroblast growth factor (FGF2). We also evaluated the methylation profile of the Long Interspersed Nucleotide Element 1 (LINE-1). PDGFB, FGF2 and LINE-1, but not TGFB, were significantly differently methylated in PMF compared to controls. Significantly, PDGFB hypomethylation (
