摘要
目的探讨植物微小RNA(microRNA,miRNA)跨物种调控对调节人类健康及疾病的新机制。方法对近年来有关植物miRNA跨物种调控人类健康及疾病新机制的相关文献进行综述。结果植物化学物质在维持人类的健康及调节疾病中起到了重要作用,植物miRNA跨物种调控同样起到重要作用,其可能的调控机制为成熟植物miRNA通过胃肠道途径完整进入动物体内,其首先通过胃肠道后再进入小肠分泌的微泡中,经过动物的循环系统靶向运往器官或组织处,通过胃肠道途径的植物miRNA与靶mRNA高度匹配进行结合并发挥其生物学调控作用。结论尽管已有研究证实植物miRNA可以跨胃肠道调控动物特定生物学功能,为植物参与调控人类健康及疾病发生、发展的新机制提供了实验依据,但是食物中的miRNA是否受加工、运输、储存方式的影响以及影响程度仍需深入挖掘;同时动物内存在的植物miRNA含量很低,不同动物体内的植物miRNA的种类也不尽相同。虽然上述问题仍未解决,但是相信随着研究的不断进展,掌握miRNA跨物种调控的机制会对预防人类疾病和保持机体健康有巨大帮助。
Objective To explore new mechanisms of cross-species regulation of plant microRNA(miRNA) to regulate human health and disease. Method The recently relevant literatures on the new mechanisms of cross-species regulation of the plant miRNA for the health and disease of human were reviewed. Results The phytochemicals played an important role in the maintaining human health and regulating diseases, and the plant miRNA cross-species regulation also played an important role in it. Its possible regulatory mechanism was that the mature plant miRNA came into the animal body through the gastrointestinal tract. It firstly passed through the gastrointestinal tract and then came into the microvesicles secreted by the small intestine. It was targeted to the organ or tissue through passing of the animal circulatory system. The plant miRNA passing through the gastrointestinal tract was highly matched with the target mRNA to perform its biological regulatory role. Conclusions Although studies have confirmed that plant miRNA can regulate animal specific biological functions across gastrointestinal tract and it provides an experimental basis for plants to participate in new mechanisms for regulating occurrence and development of human health and disease, whether or not miRNA in food is affected by way it is processed, transported, stored, and extent to which it is affected, remains to be explored. At the same time, content of plant miRNA in animals is very low and types of plant miRNA in different animals are not same. Although the above issues have been unresolved, it is believed that with research progresses, mastering mechanism of miRNA cross-species regulation will greatly help to prevent human diseases and maintain health of body.
