摘要
DNA加合物是评价DNA损伤最直接的分子证据,随之产生一个专门研究DNA修饰识别和DNA加合物定量的新领域——DNA加合物组学。其中质谱(MS)分析法是常用的DNA加合物组学技术,并且随着质谱分析仪的灵敏度和扫描速度的提高,使得利用DNA加合物组学技术来筛查人类基因组中DNA损伤成为可能。其中,基于质谱技术对马兜铃、巴豆醛等致癌物生成的DNA加合物的种类的检测应用十分广泛。主要就基于质谱的加合物组学检测技术及其在致癌物检测中的应用进行概述。
DNA adducts are the most direct molecular evidence for evaluating DNA damage,and a new field specializing in DNA modification recognition and DNA adduct quantification—DNA adductomics has emerged.Mass spectrometry(MS)is a commonly used DNA adductomics technology,and with the increase in the sensitivity and scanning speed of mass spectrometry,the use of DNA adductomics technology to screen DNA in the human genome Damage becomes possible.The detection of DNA adducts produced by carcinogens such as aristolochia and crotonaldehyde based on mass spectrometry is very widely used.This article mainly summarizes the adductomics detection technology based on mass spectrometry and its application in the detection of carcinogens.
