摘要

微小核糖核酸（miRNA）是一种小型非编码核糖核酸，可通过降解或抑制 mRNA 翻译成蛋白质来控制基因表达。最近的研究表明，从食物中提取的 miRNA 具有生物可利用性，可能会被胃肠道（GIT）吸收。由于这些小核糖核酸可能进入血液循环和器官，因此可能与宿主基因发生相互作用，从而产生改变新陈代谢的表观遗传效应。因此，从精准营养的角度来看，外源 miRNA 可能是调节健康状况的关键。本综述概述了 miRNA 的生物发生过程、基因翻译后的调控机制以及它们在动物和植物源性食品中的生物利用率。

MicroRNA Biogenesis, Gene Regulation Mechanisms, and Availability in Foods.

MicroRNAs (miRNAs) are small, non-coding RNAs that control gene expression by degrading or repressing mRNA translation into proteins. Research recently suggested that food-derived miRNAs are bioavailable and may be absorbed in the gastrointestinal tract (GIT). Since these small RNAs may reach the circulation and organs, possible interactions with host genes will lead to epigenetic effects that alter metabolism. Therefore, from a precision nutrition standpoint, exogenous miRNAs may be essential in modulating health status. This review summarizes the process of miRNA biogenesis, the post-translational mechanisms of gene regulation, and their bioavailability in animal- and plant-derived foods.
