摘要:


文题释义:
微小RNA-146a:微小RNA(microRNA,miRNA)是一类由21-23个核苷酸构成的内源性非编码单链RNA,其能与mRNA的3’非编码区域(3’URT)完全配对诱导目标mRNA的直接降解,或不完全配对抑制mRNA的翻译,从而抑制蛋白质的合成,实现基因沉默。其中miR-146a在人体内由5号染色体上的LOC285628基因编码,可在多种组织细胞中表达,参与调控机体代谢、组织发育、炎症刺激的免疫反应等生物学过程。
miR-146a在骨代谢相关疾病的发展过程中变化显著,miR-146a可能作为骨代谢疾病诊疗的潜在靶点。
骨代谢:是骨细胞间以及骨细胞与基质细胞间通过相互作用进行骨改建和重建。稳定的骨代谢能形成并维持具有正常结构和功能的骨组织,骨代谢异常则是骨质疏松、骨关节炎、牙周炎等骨代谢疾病的主要发病机制。骨代谢过程的关键细胞成骨细胞、破骨细胞生物学行为异常,或组织周围炎症微环境均会造成骨代谢过程失衡,引发骨代谢相关疾病。

背景:正常骨代谢有赖于成骨细胞介导的骨形成与破骨细胞介导的骨吸收之间的平衡,破坏该平衡会引发骨代谢相关疾病。微小RNA-146a (miR-146a)是一种非编码小分子RNA,在骨代谢中发挥重要作用。
目的:就微小RNA-146a调控骨代谢的分子机制及其在骨组织工程中的应用做一综述。
方法:作者于2025年4月对中国知网、PubMed和Web of Science数据库中2000年1月至2025年4月发表的相关文献进行检索,中文检索词为“微小RNA-146a,骨,骨代谢,成骨细胞,破骨细胞,骨组织再生”;英文检索词为“microRNA-146a,Bone metabolism,Osteoblast,Osteoclast,Bone  regeneration”,检索文献类型不限。共检索到文献11 230篇,其中中国知网检索到中文文献988篇,PubMed数据库检索到英文文献5 952篇,Web of Science数据库检索到英文文献4 290篇。目标纳入研究骨代谢过程及其影响因素的相关文献,探究微小RNA-146a如何调控骨代谢过程、骨代谢关键细胞生物学行为的相关文献,微小RNA-146a应用于维持骨稳态、促进骨组织修复再生的相关文献;排除与文章主题相关度低、内容较陈旧、实验设计不严密、研究结果可信度较差、论证不充分的文献。最终根据文献排除标准筛选出与该综述主题密切相关且研究新颖、数据真实可信、论证充分、具有临床应用价值的90篇文献进行综述。
结果与结论:①微小RNA-146a可通过抑制Wnt、Smad4、沉默信息调节因子2相关酶1等基因表达抑制成骨细胞形成及活性,或通过抑制肿瘤坏死因子受体相关因子6、白细胞介素1受体相关激酶1基因表达抑制破骨细胞形成,也可调节成骨细胞与破骨细胞的相互作用;②微小RNA-146a的异常表达可使成骨细胞和破骨细胞功能失调,打破骨代谢平衡,引发骨质疏松、骨关节炎、牙周炎等骨代谢相关疾病;③因此,微小RNA-146a可作为骨代谢相关疾病诊疗的潜在靶点,在骨代谢相关疾病治疗和骨组织工程中具有一定的应用前景。

Abstract: BACKGROUND: Normal bone metabolism relies on the balance between osteoblast-mediated bone formation and osteoclast-mediated bone resorption. Disruption of this balance can lead to bone metabolism-related diseases. MicroRNA-146a is a non-coding small RNA molecule that plays a crucial role in bone metabolism.
OBJECTIVE: To review the molecular mechanisms by which microRNA-146a regulates bone metabolism and its applications in bone tissue engineering.
METHODS: In April 2025, the authors conducted a search of relevant literature published from January 2000 to April 2025 in the CNKI, PubMed, and Web of Science databases. The search terms used in Chinese included microRNA-146a, bone, bone metabolism, osteoblast, osteoclast, and bone tissue regeneration. The English search terms were microRNA-146a, bone metabolism, osteoblast, osteoclast, and bone regeneration. There is no restriction on  the type of retrieved liter ature. A total of 11 230 documents were retrieved, comprising 988 Chinese documents from CNKI, 5 952 English documents from PubMed, and 4 290 English documents from Web of Science. The included literature focused on the process of bone metabolism and its influential factors, the regulation of bone metabolism by microRNA-146a, the biological behavior of key cells involved in bone metabolism, and the application of microRNA-146a in maintaining bone homeostasis and promoting bone tissue repair and regeneration. Literature with low relevance to the topic, outdated content, inadequate experimental design, poor credibility of research results, and insufficient argumentation were excluded. Based on the eligibility criteria, 90 articles closely related to the theme of this review—characterized by novel research, authentic and reliable data, sufficient argumentation, and clinical application value—were included in the final analysis.
RESULTS AND CONCLUSIONS: (1) MicroRNA-146a can inhibit the formation and activity of osteoblasts by suppressing the expression of genes such as Wnt, Smad4, and silencing information regulator 2-related enzyme 1. It can also inhibit the formation of osteoclasts by suppressing the expression of genes such as tumor necrosis factor receptor-associated factor 6 and interleukin-1 receptor-associated kinase 1. Additionally, it can regulate the interaction between osteoblasts and osteoclasts. (2) Abnormal expression of microRNA-146a can lead to dysfunction in osteoblasts and osteoclasts, disrupt the balance of bone metabolism, and induce osteoporosis, osteoarthritis, periodontitis, and other bone metabolism-related diseases. (3) MicroRNA-146a may serve as a potential target for the diagnosis and treatment of bone metabolism-related diseases, offering promising applications in the treatment of bone metabolism-related diseases and in bone tissue engineering.
