线粒体为生理功能提供能量,并参与调节其他细胞事件,包括细胞凋亡、钙稳态和活性氧的产生。因此,线粒体在细胞中起着关键作用。然而,线粒体功能障碍与多种病理过程和疾病有关。microRNA(miRNAs)是一类长度约为22个核苷酸的非编码小RNA,可与mRNA的3′非翻译区(3′UTR)结合,从而抑制mRNA的翻译或促进mRNA的降解。本文综述了miRNAs对线粒体代谢、结构和功能的分子调控。调节miRNAs的水平可能为治疗糖尿病相关疾病提供一种新的治疗方法。
Mitochondria supply energy for physiological function and they participate in the regulation of other cellular events including apoptosis, calcium homeostasis and production of reactive oxygen species. Thus, mitochondria play a critical role in the cells. However, dysfunction of mitochondria is related to a variety of pathological processes and diseases. MicroRNAs (miRNAs) are a class of small noncoding RNAs about 22 nucleotides long, and they can bind to the 3′ un-translated region (3′UTR) of mRNAs, thereby inhibiting mRNA translation or promoting mRNA degradation. We summarize the molecular regulation of mitochondrial metabolism, structure and function by miRNAs. Modulation of miRNAs levels may provide a new therapeutic approach for the treatment of mitochondria-related diseases.
