Progress on pathogenesis of essential thrombocythemia / 国际儿科学杂志

ABSTRACT

Essential thrombocythemia (ET) which is a clonal disease of hematopoietic stem cell mainly reflects hyperplasia of megakaryocyte. Childhood ET is characterized by persistance of thrombocytosis, mild to moderate hepatomegalia and splenomegalia, thrombogenesis and hemorrhage complications. The pathogenesis of ET is obviously associated with the abnormal or disturbance expression of multiple genes, micro RNAs,immunological molecules and some chromosome aberration. This review will focus on recent developments in the pathogenesis of ET in molecular biology, immunology and cytogenetics.
