miRNA与慢性髓系白血病研究进展

摘要

microRNA (miRNA)是一种内源性的、长度约为22 nt的小非编码RNA,在转录后水平参与调控基因表达,广泛参与细胞的凋亡、增殖、分化、代谢等过程,具有重要的生物功能,并且可行使癌基因或抑癌基因功能.研究表明,miRNA的异常表达与慢性髓系白血病密切相关,参与调控慢性髓系白血病的发生、进展及耐药等过程,可成为潜在的诊疗靶点.本文就miRNA的合成与作用方式、慢性髓系白血病发病、耐药、治疗相关miRNA的研究进展作一综述.%microRNA(miRNA) are about 22 nucleotide (nt) endogenous small non-coding RNA that play an important role in regulation of gene expression at the post-transcriptional level. miRNA control the expression of genes involved in several biologic processes, including apoptosis, proliferation, differentiation and metabolism of cells. miRNA can also act as oncogenes or antioncogenes. Abnormal expression of miRNA is associated with chronic myelogenous leukemia (CML) and contributes to the pathogenesis, disease progression, and response to therapy of CML. They may also serve as the potential therapy targets in the disease. In this review, the most important findings about the biogenesis pathway and function of miRNA as well as the role of miRNA in the pathogenesis, drug-resistance and therapy of CML are discussed.
