Research progress of microRNA in the transformation from myelodysplastic syndromes into acute leukemia / 白血病·淋巴瘤

ABSTRACT

microRNA (miRNA) is a kind of 18 to 25 nucleotide non coding RNAs,which plays an important role in various ways.The abnormal miRNA expression patterns lead to many diseases of hematopoietic system.Myelodysplasitc syndromes (MDS) comprise a heterogeneous group of disorders characterized by ineffective hematopoiesis,bone marrow dysplasia and variable propensity of transformation to acute myeloid leukemia (AML).20 ％-30 ％ MDS patients may progress to AML.miRNA plays a key role in the develpoment,advance and prognosis of MDS.In this paper,the related miRNAs in the transformation from MDS into AML were reviewed.
