Myeloproliferative neoplasms (MPN) are hematological malignancies characterized by uncontrolled cell proliferation and impaired apoptosis. The FasR/FasL system is involved in the control of apoptosis in different cell types. Here we have investigated the role of FasR/FasL in the pathogenesis of MPNs. We compared FasR/FasL expression between MPN patients (24) and healthy individuals using the real-time PCR assay. We found an increase of FasR expression in MPN patients. No difference was detected in FasL expression. Mutation V617F in the JAK2 gene, a hallmark of MPN, was detected in 13/24 patients. We found that neither FasR nor FasL expression were related to the presence of JAK2 V617F mutation.
