Abstract

5-Formyluracil, a major oxidized form of thymine, was incorporated into a predetermined site of one of the leading and lagging template strands of a double-stranded vector, and the DNA replication efficiency and the mutation frequency of 5-formyluracil in simian COS-7 cells were investigated. 5-Formyluracil did not block DNA replication and was weakly mutagenic in simian cells. 5-Formyluracil primarily elicited base substitutions at the modified positions.

5-甲酰基尿嘧啶在哺乳动物细胞中的致突变性。
将胸腺嘧啶的一种主要氧化形式5-甲酰基尿嘧啶(5-甲酰基尿嘧啶)加入到双链载体的前导和滞后模板链的预定位点,研究了5-甲酰基尿嘧啶在猿猴COS-7细胞中的DNA复制效率和突变频率。5-甲酰基尿嘧啶不阻断DNA复制,在猿猴细胞中具有弱致突变性。5-甲酰基尿嘧啶主要在修饰位置引起碱基取代。
