摘要 天然反义转录物(natural antisense transcripts,NATs)是在自然情况下生物体内产生的内源性RNA,它们与其对应的互补RNA通过碱基配对,形成自然正义—反义转录物配对的双链RNA,对器官形成、细胞分化和疾病发生等各种生理和病理过程都有重要的调控作用。该文综述了近年来NATs的研究进展,从正反馈调节和负反馈调节两个方面介绍了NATs对正义转录物的影响,从RNA编辑、RNA干扰、RNA封闭、转录干扰、DNA甲基化和组蛋白修饰等方面详细阐述了NATs的作用机制,并介绍了NATs与疾病的关系。NATs是一种丰富的生物分子资源,可用于表观遗传学,未来有潜在的诊断和治疗价值。 Natural antisense transcripts （NATs） can represent coding or, more commonly, noncoding RNA, which are generated inside the organism under natural condition and widely expressed in various species. NATs play important roles in the regulation of organ development, cell differentiation and disease occurrence. By review-ing the latest advance about NATs in recent years, this article described the effects of NATs on sense transcription by discordant regulation and concordant regulation. The related mechanism of NATs was also introduced from RNA editing, RNA interference, RNA blocking, transcriptional interference, DNA methylation and histone modification, and the relationship between NATs and disease was also described. NATs may represent a potentially abundant source ofbiomolecules for use in epigenetics and have great potential diagnostic and therapeutic value in future.
