摘要: MicroRNAs是一类由20-24个核苷酸组成的非编码单链RNA,通过结合于靶基因的 mRNA 的 3’UTR,负向调控基因表达。骨形成是一个复杂的过程,其中涉及了多种细胞的分化和交联来完成骨的形成和重塑。研究证明,miRNA调控骨发生发展和出生后的功能的多个层面。目前,miRNA已被认为是调控骨发育与维持骨稳态的重要调节因子。该文主要针对目前关于miRNA调控骨形成和骨吸收相互作用的研究及其进展作一综述。

Abstract: MicroRNAs (miRNAs) are the class of noncoding single-stranded RNA molecules composed of approximately 20–24 nucleotides. These small miRNAs bind to complementary sequences in the 3' untranslated region (UTR) of mRNAs to negatively regulate gene expression. Bone organogenesis is a complex process, which involves the differentiation and crosstalk of multiple cell types for formation and remodeling of the skeleton. The existing evidence indicates that miRNAs control multiple layers of gene regulation for bone development and postnatal functions. Currently, inhibition of mRNA translation by miRNAs has been regarded as an important regulator for bone development and homeostasis. This review focuses on the current knowledge of miRNAs and their involvement in the regulation of bone formation and bone resorption.
