1基于质谱的蛋白质组学方法新进展显示文摘蛋白质组学是后基因组时代的科研热点,其研究方向主要涵盖蛋白质表达谱、蛋白质翻译后修饰谱、蛋白质相互作用谱和单细胞蛋白质组等定性分析以及相对和绝对定量分析,现已广泛应用于生物、医药及病理研究中。由于质谱具有灵敏、准确、高通量等特点,是蛋白质组学研究必不可少的工具。本文综述了近年来基于质谱技术的蛋白质组鉴定及定量方法,并展望未来蛋白质组学研究的发展方向。季美超 付斌 张养军 2021质谱学报2021,42,5:13
2Cucurbit[7]uril as a Broad-Spectrum Antiviral Agent against Diverse RNA Viruses显示文摘The emergence and re-emergence of RNA virus outbreaks highlight the urgent need for the development of broadspectrum antivirals.Polyamines are positively-charged small molecules required for the infectivity of a wide range of RNA viruses,therefore may become good antiviral targets.Cucurbit[7]uril(CB[7]),a synthetic macrocyclic molecule,which can bind with amine-based organic compounds with high affinity,has been shown to regulate bioactive molecules through competitive binding.In this study,we tested the antiviral activity of CB[7]against diverse RNA viruses,including a panel of enteroviruses(i.e.human enterovirus A71,coxsackievirus A16,coxsackievirus B3,and echovirus 11),some flaviviruses(i.e.dengue virus and Zika virus),and an alphavirus representative Semliki forest virus.CB[7]can inhibit virus replications in a variety of cell lines,and its mechanism of action is through the competitive binding with polyamines.Our findings not only for the first time provide evidence that CB[7]can be a promising broad-spectrum antiviral agent,but more importantly,offer a novel therapeutic strategy to fight against RNA viruses by supramolecular sequestration of polyamines.Jia Quan Xiangjun Zhang Yuanfu Ding Shengke Li Yang Qiu Ruibing Wang Xi Zhou 2021Virologica Sinica2021,36,5:0
