Increased circulating procoagulant activity and thrombin generation in patients with myeloproliferative neoplasms.

Microparticles (MPs) are membrane fragments ranging in size from 0.1 to 1 microm, and are considered as biomarkers reflecting prothrombotic state in many clinical diseases. The clinical course of myeloproliferative neoplasms (MPN) being frequently complicated by thrombotic events, we determined the MPs activity, i.

Interlaboratory development and validation of a HRM method applied to the detection of JAK2 exon 12 mutations in polycythemia vera patients.

Background: Myeloproliferative disorders are characterized by clonal expansion of normal mature blood cells. Acquired mutations giving rise to constitutive activation of the JAK2 tyrosine kinase has been shown to be present in the majority of patients. Since the demonstration that the V617F mutation in the exon 14 of the JAK2 gene is present in about 90% of patients with Polycythemia Vera (PV), the detection of this mutation has become a key tool for the diagnosis of these patients.
