microRNA调控肝缺血再灌注损伤的作用机制

Mechanism of action of microRNA in the regulation of hepatic ischemia-reperfusion injury

肝缺血再灌注损伤是影响临床肝外科手术预后的重要原因之一。研究发现microRNA可通过多条途径参与肝缺血再灌注损伤过程。归纳总结了microRNA的生物合成与功能及其通过能量代谢、凋亡、自噬、氧化应激和细胞炎症等途径调控肝缺血再灌注损伤的相关机制。认为以microRNA为靶点治疗肝缺血再灌注损伤有广阔的应用前景,期待之后更深入的研究。

Hepatic ischemia-reperfusion injury is one of the most important factors affecting the prognosis of clinical hepatic surgery. Studies have shown that microRNAs can participate in the process of hepatic ischemia-reperfusion injury through multiple pathways. This article reviews the biosynthesis and function of microRNAs and the mechanisms of action of microRNAs in the regulation of hepatic ischemia-reperfusion injury through energy metabolism, apoptosis, autophagy, oxidative stress, and cellular inflammation. It is pointed out that the treatment targeting microRNAs has a promising future in the treatment of hepatic ischemia-reperfusion injury, and further studies are needed in the future.
