Epigenetics in Myeloproliferative Neoplasms

Effects of Mutational Combinations on Philadelphia-Negative Myeloproliferative Neoplasms

Hyper eosinophilia associated with myeloid and lymphoid neoplasms

Eosinophilia in the absence of allergies, asthma, drug reactions, parasitic infections and connective tissue diseases can be eosinophilic clonal disorders, lymphoma or myeloproliferative disorders. Hypereosinophilia with the persistence of eosinophils ≥1500 /mm³ in blood or more than 20% of eosinophils in the bone marrow may be observed in many reactive or clonal disorders, the result of which ...

Myeloproliferative Neoplasms Associated with Mutation in JAK2V617F and Tyrosine Kinase Inhibitors as Therapeutic Strategy

MPNs including a heterogeneous group of clonal or oligoclonal hamtopathies characterized by proliferation and accumulation of mature myeloid cells. JAK2 tyrosine kinase mutation is the most common molecular lesion identified in 90% of cases. JAK2 is involved in EPO signaling pathway, and mutations in it lead to EPO-independent spontaneous phosphorylation. Most tyrosine kinase inhibitors (TKI) a...

Epigenetic therapy in myeloproliferative neoplasms: evidence and perspectives

The classic Philadelphia chromosome-negative myeloproliferative neoplasms (MPNs), which include polycythaemia vera, essential thrombocythaemia and primary myelofibrosis, originate from a stem cell-derived clonal myeloproliferation that manifests itself with variable haematopoietic cell lineage involvement; they are characterized by a high degree of similarities and the chance to transform each ...

Epigenetics and mutations in chronic myeloproliferative neoplasms.

The BCR-ABL1-negative classic myeloproliferative neoplasms, polycythemia vera (PV), essential thrombocytemia (ET) and primary myelofibrosis are clonal stem cell disorders associated with an increased production of mature blood cells belonging preferentially to one cell linage. They share substantial phenotypic mimicry, can undergo phenotypic shifts (from PV to ET and vice versa) as well as evol...
