| 摘要：miRNAs 是一类短的（20-23nt）非编码的单链RNA分子，在转录后水平上通过抑制靶基因的表达而影响生物体的生长、发育
以及癌症发生。miRNAs的成熟需要一系列大型蛋白复合体参与的协同加工，目前对miRNAs 生物合成过程调控的研究还处于初
始阶段。本文主要综述了影响miRNAs的生物合成过程及活性的因素以及相关调控机制。癌症的发生通常伴随着异常的miRNAs
表达谱，miRNAs生物合成调控机制的深入研究必将为癌症的基因治疗技术以及新型疗法的开发提供重要的理论基础和指导意
义。 |
| 英文摘要: |
| ABSTRACT:MicroRNAs(miRNAs) are short(20-23-nucleotide), non-coding and single-stranded RNA molecules which regulate
target gene expression at the post-transcriptional level to affect organisms' growth, development and cancer occurence. The maturity of
miRNAs need a series of collaborative process mediated by large protein complexes and researches of miRNAs biosynthesis and activity
controlare still in initial stage at present. This review mainly discusses the influencing factors of miRNAs biosynthesis and activity and
relevant regulation mechanism. Cancer occurrence is usually accompanied by abnormal miRNAs expression profile, and further study for
regulation mechanism of miRNAs biosynthesis will surely provide important theoretical basis and guidance for gene therapy of cancer
and development of new technology. |
