摘要: N4-乙酰胞苷(N4-acetylcytidine,ac4C)是一类新兴的RNA表观修饰,近年来在表观转录组学研究中被广泛关注。该修饰广泛存在于tRNA、rRNA、mRNA及非编码RNA中,通过精准调控RNA的稳定性与翻译效率,影响下游基因的表达网络,进而对细胞功能产生重要影响。本文综述了ac4C修饰的分布特征、生物学功能及复杂调控机制的最新研究进展,详细介绍了其编码器、检测方法以及在动物生殖发育中的作用,旨在为深入探讨ac4C修饰在动物繁殖与人类生殖等领域的调控机制提供坚实的理论基础与研究思路。

Abstract: N4-acetylcytidine (ac4C) is an emerging RNA epigenetic modification that has attracted considerable attention in the field of epitranscriptomics in recent years. This modification is widely present in tRNA, rRNA, mRNA, and various non-coding RNAs. By precisely regulating RNA stability and translational efficiency, ac4C modulates the expression network of downstream genes, thereby playing a critical role in cellular function.In this review, we summarize recent advances in the distribution patterns, biological functions, and regulatory mechanisms of ac4C, highlight the associated writer enzymes, detection methodologies, and the involvement of ac4C in animal reproductive development. We aim to provide a solid theoretical foundation and valuable research insights for future investigations into the regulatory mechanisms of ac4C modification in animal and human reproduction.
