Abstract

Quinones are potent genotoxic agents through generating reactive oxygen species or undergo covalent bonding to modify the nucleobases of DNA. The formation of DNA adducts is an early indication of cancer, as it may lead to gene mutation, thereby initiating tumor development. The present review aims to summarize different types of quinone-induced DNA damages and the corresponding DNA adducts. In addition to the considerably stable naphthoquinone and halobenzoquinones in the environment, quinones are also metabolically activated from estrogen, bisphenol A, ochratoxin A, polychlorinated biphenyls, benzo[a]pyrene and polybrominated diphenyl ethers, in which the inducement from these pollutants to produce DNA adducts were systematically discussed. Liquid chromatography-mass spectrometry (LC-MS)-based method with high accuracy and sensitivity for the detection of DNA adducts in mononucleotides, DNA duplexes, and biological samples was methodically summarized. It is believed that the presence of dione moiety in quinones is an imperative element that induce the formation of DNA adducts. The investigation on DNA adducts is helpful for understanding the generation, transformation, and repair of DNA damages, and for elucidating the underlying mechanism of carcinogenesis. This review provides a new perspective to assess the toxicological potential of quinones, and intends to put forward strategies of analyzing DNA adducts, which act as biomarkers, for indicating the potential health risks of multiDNA damages.

醌的基因毒性:对 DNA 加合物及其基于 LC-MS 的检测的见解

摘要

醌是有效的基因毒剂,通过产生活性氧或通过共价键修饰 DNA 的核碱基。DNA 加合物的形成是癌症的早期迹象,因为它可能导致基因突变,从而引发肿瘤发展。本综述旨在总结不同类型的醌诱导的 DNA 损伤和相应的 DNA 加合物。除了环境中相当稳定的萘醌和卤代苯醌之外,雌激素、双酚 A、赭曲霉毒素 A、多氯联苯、苯并[a]芘和多溴联苯醚也会对醌进行代谢活化,这些污染物会诱导产生 DNA系统地讨论了加合物。系统总结了基于液相色谱-质谱 (LC-MS) 的方法,该方法具有高精度和灵敏度,可用于检测单核苷酸、DNA 双链体和生物样品中的 DNA 加合物。据信,醌中二酮部分的存在是诱导 DNA 加合物形成的必要因素。DNA加合物的研究有助于了解DNA损伤的产生、转化和修复,以及阐明致癌作用的潜在机制。本综述为评估醌的毒理学潜力提供了新的视角,并旨在提出分析作为生物标志物的 DNA 加合物的策略,以指示多 DNA 损伤的潜在健康风险。对生物样本进行了有条不紊的总结。据信,醌中二酮部分的存在是诱导 DNA 加合物形成的必要因素。DNA加合物的研究有助于了解DNA损伤的产生、转化和修复,以及阐明致癌作用的潜在机制。本综述为评估醌的毒理学潜力提供了新的视角,并旨在提出分析作为生物标志物的 DNA 加合物的策略,以指示多 DNA 损伤的潜在健康风险。对生物样本进行了有条不紊的总结。据信,醌中二酮部分的存在是诱导 DNA 加合物形成的必要因素。DNA加合物的研究有助于了解DNA损伤的产生、转化和修复,以及阐明致癌作用的潜在机制。本综述为评估醌的毒理学潜力提供了新的视角,并旨在提出分析作为生物标志物的 DNA 加合物的策略,以指示多 DNA 损伤的潜在健康风险。和修复 DNA 损伤,以及阐明致癌作用的潜在机制。本综述为评估醌的毒理学潜力提供了新的视角,并旨在提出分析作为生物标志物的 DNA 加合物的策略,以指示多 DNA 损伤的潜在健康风险。和修复 DNA 损伤,以及阐明致癌作用的潜在机制。本综述为评估醌的毒理学潜力提供了新的视角,并旨在提出分析作为生物标志物的 DNA 加合物的策略,以指示多 DNA 损伤的潜在健康风险。
