英文摘要

New AdvancMolecular Pathogenand es in esis diagnosis of Essential Thrombocythemia

ABSTRACT

myeloproliferativneoplasm(MPN),is a hematopoietic diso

e rder

that is characterized clinically by thrombocytosis which results from bone marrow megakaryocyte hyperplasia.Patients with ET Essential thrombocythemia (ET),

a subtypof e

are at

increased risk for developing thrombosis,hemorrhage, myelofibrosis and transformato acutmyeloid leukemie

tion a. The molecular pathogenesis of ET largely to be fully remains understood but the identification of the JAK2V6 1 7F mutation in

more than half of s was

ET patienta

major improvemenin t

our

and ma the first of this disease represenunderstandit y ng biologic marker useful for ristratification and diagnosis.Bsk there iS still ut

asubset of patients with JAK2V6 1 7F.negative ET, and some of these patients have been identified gain-of-function mutations in the thrombopoiereceptor(MPL)in subsequent tin studies.Since the discovery of JAK2V6 1 7F iS

advance in

our understanding of the molecular pathogenesis of ET.WHO revised the diagnostic criteria for ET'which 10wered the platelet threshold for

allows JAK2V6 1 7F deteto demonstrate the presencction e of

are both related

with the activation of

JAK-STAT signaling transduction pathway,specific inhibitors of JAK2 kinase activity have been designed and have entered clinic trials.
