竞争性内源性RNA网络在慢性肾衰竭中的作用及中医药干预研究进展

Roles of the competitive endogenous RNA network in chronic renal failure and research progress in traditional Chinese medicine interventions

  • 摘要: 慢性肾衰竭(CRF)并发症多,预后欠佳,治疗手段有限。近年研究显示,由长链非编码RNA(lncRNA)和环状RNA介导的竞争性内源RNA(ceRNA)网络在CRF中广泛参与炎症激活、氧化应激、凋亡、肾纤维化、细胞外基质成分与结构重塑、铁死亡等病理环节,介导形成了CRF进程中“炎症-损伤-纤维化”的病理环路,从而使lncRNA成为潜在的治疗靶点。然而,现有研究多聚焦于单一ceRNA轴,缺乏对网络中枢节点及动态调控规律的系统分析。文章对ceRNA网络在CRF中的作用机制进行综述,分析中医药对ceRNA网络关键靶点的干预作用,为从分子生物学角度诠释中医药的作用提供新视角。中医药“多成分、多靶点”的作用特点与ceRNA网络的复杂性高度契合,可通过抗炎、抗肾纤维化、改善细胞损伤与凋亡、减少细胞外基质沉积等多种途径,有效延缓CRF的发生与进展。

     

    Abstract: Chronic renal failure (CRF) is associated with multiple complications, a poor prognosis, and limited therapeutic options. Recent studies have shown that the competitive endogenous RNA (ceRNA) network mediated by long non-coding RNAs (lncRNAs) and circular RNAs is widely involved in pathological processes of CRF, such as inflammation activation, oxidative stress, apoptosis, renal fibrosis, extracellular matrix component and structural remodeling, and ferroptosis. It mediates the formation of the pathological loop of “inflammation-injury-fibrosis” during the progression of CRF, thus making it a potential therapeutic target. However, most current studies focus on a single ceRNA axis and lack systematic analysis of the central nodes and dynamic regulatory mechanisms of the network. This article reviews the mechanism of the ceRNA network in CRF and analyzes the intervention effect of traditional Chinese medicine (TCM) on key targets of the ceRNA network, providing a new perspective for interpreting the effects of TCM from the perspective of molecular biology. The “multi-component, multi-target” characteristic of TCM is highly consistent with the complexity of the ceRNA network. TCM can effectively delay the occurrence and development of CRF through multiple pathways, such as anti-inflammation, anti-renal fibrosis, improving cell injury and apoptosis, and reducing extracellular matrix deposition.
