microRNA(miRNAs)是一种约22个核苷酸的RNA,在动物体内协调巨大的调控网络,从而影响无数的过程。本文综述了miRNAs在成年人中发挥持续作用的证据,这些作用与发育控制是分开的。在神经功能和心血管生物学的背景下,在代谢和生理学中,以及在癌症期间,已经在各种干细胞群体中描述了miRNA的成人特异性活性。除了回顾最近的结果,我们还讨论了专门研究成年人miRNA活性的方法,并评估了它们的相对优势和劣势。对成年人中miRNA的连续功能的更全面的理解与操纵miRNA用于治疗目的的努力和机会有关。
microRNAs (miRNAs) are ~22 nucleotide (nt) RNAs that coordinate vast regulatory networks in animals, and thereby influence myriad processes. This review examines evidence that miRNAs play continuous roles in adults, in ways that are separable from developmental control. Adult-specific activities for miRNAs have been described in a variety of stem cell populations, in the context of neural function and cardiovascular biology, in metabolism and physiology, and during cancer. In addition to reviewing recent results, we also discuss methods for studying miRNA activities specifically in adults and evaluate their relative strengths and weaknesses. A fuller understanding of continuous functions of miRNAs in adults has bearing on efforts and opportunities to manipulate miRNAs for therapeutic purposes.
