G-quadruplexes (G4s) are non-canonical nucleic acids secondary structures that involve in the regulation of some key biological processes, such as replication, transcription, and translation. G4s have been extensively described in the genomes of human and related diseases. In recent years, G4s were identified in several livestock viruses, including those of the emerging epidemics, like Nipah virus (NiV). Since their discovery, G4s have been developed as the potential antiviral targets, and the employment of G4 ligands or interacting proteins has helped to expound the viral infectivity and pathogenesis through G4-mediated mechanisms, and highlight the potential as therapeutic approaches. However, the comprehensively studies of G4s in livestock viruses have not been summarized. This review delves into the reported literatures of G4s in livestock viruses, particular focus on the presence, biophysical identification, and possible function of G4s in viral genome, summarizing the G4 ligands, interacted proteins and aptamers on antiviral applications. The strengths and the challenges of G4 targeting in this field are also discussed. Therefore, this review will shed new light on the future development of highly potent and targeting antiviral therapy.

深入了解 G 四链体:畜牧病毒的鉴定和潜在治疗靶点



G-四链体 (G4s) 是非经典核酸二级结构,参与一些关键生物过程的调节,例如复制、转录和翻译。G4 已在人类和相关疾病的基因组中得到广泛描述。近年来,在几种牲畜病毒中发现了 G4,包括尼帕病毒 (NiV) 等新出现的流行病的病毒。自发现以来,G4s 已被开发为潜在的抗病毒靶点,G4 配体或相互作用蛋白的使用有助于通过 G4 介导的机制阐明病毒的传染性和发病机制,并突出了作为治疗方法的潜力。然而,尚未对畜禽病毒中 G4s 的全面研究进行总结。本文深入研究了 G4s 在畜禽病毒中的报道文献,特别关注 G4s 在病毒基因组中的存在、生物物理鉴定和可能的功能,总结了 G4 配体、相互作用蛋白和适配体在抗病毒应用中的作用。还讨论了 G4 定位在该领域的优势和挑战。因此,本综述将为高效和靶向抗病毒治疗的未来发展提供新的思路。
