近年来,在RNA家族中发现了一类与基因表达调节密切相关的小分子——微小RNA(miRNA).它可以通过与特定mRNA结合或调节特定mRNA的蛋白质翻译过程来调控基因的表达,从而参与生物体的发育、衰老、死亡。本文从miRNA的生成、作用机制、特点及功能、与临床疾病和运动相关方面的关系等方面逐一阐述,揭示miRNA功能的广泛,进一步提出miRNA在体育运动这一新领域的某些展望。
In recent years, a family of small molecules (miRNAs) that are closely related to the regulation of gene expression has been found in the RNA family, which can regulate the gene expression by binding to specific mRNA or regulating the protein translation process of specific mRNA Participate in organism development, aging, death. This article elaborates on the generation of miRNA, its mechanism of action, its features and functions, and its relationship with clinical diseases and sports, revealing the wide range of miRNA functions and further put forward some prospects of miRNA in the new field of sports.
