Monofunctional alkylating agent n - methyl - n ' - nitro - n - nitrosoguanidine ( mnng ) is a widely spread environmental mutagen and carcinogen that targets dna and proteins to generate adducts . among the adducts , o6 - alkyl guanine is the predominant mutagenic lesion because of its mispairing properties , which can eventually lead to chromosomal aberrations , point mutations , and cell death . this lesion also appears to be involved in tumor initiation , particularly in gastric carcinogenesis 單功能烷化劑n -甲基- n -硝基- n -亞硝基胍( mnng )是一種在環境中廣泛存在的化學誘變劑和致癌劑,它能和dna及蛋白質等生物大分子形成加合物( adduct ) ,其引起的與突變有關的主要dna損傷類型是o ~ 6 -甲基鳥嘌呤,這種損傷與腫瘤尤其是胃癌的發生密切相關。
