摘要:

MicroRNA (miRNA)是一类大小在22 nt左右的单链非编码短RNA分子,已被证明参与了几乎所有细胞事件中基因表达的转录后调节,包括细胞增殖、迁移、分化和凋亡。因此,miRNA受到最为广泛的研究和关注。miRNA通过靶向骨骼肌再生不同阶段的关键因素,在肌肉再生过程中发挥着重要作用。本文探讨了miRNA在肌肉再生过程中通过影响卫星细胞静止、成肌细胞增殖、分化从而调控肌肉再生能力,并且更新了miRNA在肌肉再生过程中与PI3K/AKT、TGF-β/Smad信号通路互作的研究进展,有助于研究者更多地了解miRNA在肌肉再生生物学中的知识,为非编码RNA参与肌肉再生提供更深入的理解。

Abstract:

MicroRNA (miRNA) is a class of single-stranded non-coding short RNA molecules about the size of 22 nt. Currently, miRNA has received the most extensive research and attention, and miRNA has been shown to be involved in the post-transcriptional regulation of gene expression in almost all cellular events, including cell proliferation, migration, differentiation, and apoptosis. miRNA plays an important role in the process of muscle regeneration by targeting key factors at different stages of skeletal muscle regeneration. In this review, we summarize the role of miRNA in regulating muscle regeneration by affecting satellite cell quiescence, myoblast proliferation, and differentiation during muscle regeneration, and update the relationship between miRNA and PI3K/AKT, TGF-β/Smad signaling during muscle regeneration. The research progress of pathway interaction will help researchers to learn more about the knowledge of miRNA in muscle regeneration biology, and provide a better understanding of the involvement of non-coding RNAs in muscle regeneration.
