摘要:

文题释义:
miR-214:是一类重要的非编码小RNA分子,是脊椎动物特有的miRNA,它主要通过与靶基因的mRNA3’UTR区域结合,在转录后的水平沉默靶基因的表达,从而影响其参与的通路及生物进程。
骨重建(Bone remodeling):是指骨组织的形态和密度随着生物力学环境的改变而改变的生理行为。骨重建的过程以骨多细胞单位为基本单位进行,主要由破骨细胞的骨吸收和成骨细胞的骨形成调节。

背景:microRNAs是一类重要的内源性非编码小RNA分子,可通过调节mRNA的翻译调控基因的表达。近年来发现,miR-214在相关的骨代谢信号通路中起着重要的作用,可通过靶向相关基因调控骨吸收与骨形成。
目的:通过回顾国内外相关文献,就miR-214在骨组织代谢中的调控机制及应用研究的新进展作一综述。
方法:由第一作者在2019年11月至2020年4月间以“miRNA,miR-214,osteogenesis,osteoblast”“miR-214,bone remodeling”“miR-214,osteoclast,tissue engineering”为关键词,检索2005至2020年期间PubMed、Web of Science、Medline等数据库中的文献,初步检索到761篇相关文献,排除与文章研究目的无关及重复性的文献,纳入符合标准的63篇文献进行分析。
结果与结论:①miR-214可通过靶向磷酸酶-张力蛋白同源基因(PTEN)、肿瘤坏死因子受体相关因子3促进破骨向分化,靶向转化生长因子β激活激酶1结合蛋白2(TAB2)、钙黏蛋白相关蛋白(CTNNB1)、锌 指 结 构 转 录 因 子(Osterix)、激活转录因子4(ATF4)、Ⅳ 型胶原蛋白基因 α1(COL4A1)、杆状病毒IAP重复序列7(BIRC7)、成纤维细胞生长因子受体1、TAFA趋化因子样家族成员5(TAFA5)、骨形态发生蛋白2等抑制成骨分化;②沉默或过表达miR-214可以调控骨代谢;③目前已发现血清或细胞外囊泡中miR-214可能是一些疾病诊断和预后的检测标志物,同时将miR-214拮抗剂或模拟物与其他载体构成稳定高效安全的缓释系统也是应用研究的热点,因此,以miR-214为基础展开的应用研究可能在未来骨组织代谢相关疾病的治疗方面具有较大的潜力。

Abstract: BACKGROUND: MicroRNAs (miR) is an important endogenous non-coding small RNA that regulates the expression of genes by regulating the translation of mRNA. In recent years, it has been found that miR-214 plays an important role in related bone metabolic signaling pathways, which can regulate bone resorption and bone formation by targeting related genes. 
OBJECTIVE: To review the new progress in the regulatory mechanism and possible application of miR-214 in bone metabolism.
METHODS: The first author searched PubMed, Web of Science, and Medline with the keywords of “miRNA, miR-214, osteogenesis, osteoblast,” “miR-214, bone remodeling,” and “miR-214, osteoclast, tissue engineering” respectively for relevant literature published from 2005 to 2020. A total of 761 articles were preliminarily searched, and 63 articles that were related to the research purpose were selected and analyzed.
RESULTS AND CONCLUSION: MiR-214 can promote osteoclast differentiation by targeting phosphatase-tensin homolog and tumor necrosis factor receptor associated factor 3, and inhibit osteoblast differentiation by targeting transforming growth factor β activated kinase 1 binding protein 2, cadherin protein β1, Osterix, activating transcription factor 4, α1 type IV collagen, baculovirus IAP repeat containing 7, fibroblast growth factor receptor 1, TAFA chemokine-like family member 5, and bone morphogenetic protein 2. Many studies have proved that silencing or overexpression of miR-214 can regulate bone metabolism. It is also found that miR-214 in serum or extracellular vesicles may be a marker for the diagnosis and prognosis of some diseases. It is the focus of its application research to combine miR-214 antagonists with bioscaffold materials to form a stable, efficient and safe sustained release system. Therefore, miR-214 may have great potential in the treatment of bone metabolic diseases in the future.
