摘要

5-甲酰基尿嘧啶是胸腺嘧啶的主要氧化产物,在DNA中形成,其产量与暴露于γ辐射下的8-氧-7,8-二氢鸟嘌呤相当。尽管8-氧-7,8-二氢鸟嘌呤清除的修复途径和生物学效应已经被阐明,但对5-甲酰基尿嘧啶在DNA中的细胞意义的关注却少得多。本文综述了DNA氧化损伤研究中这一重要领域的研究现状。

Cellular effects of 5-formyluracil in DNA

5-Formyluracil is a major oxidation product of thymine, formed in DNA in yields comparable to that of 8-oxo-7,8-dihydroguanine by exposure to γ-irradiation. Whereas the repair pathways for removal and the biological effects of persisting 8-oxo-7,8-dihydroguanine are much elucidated, much less attention has been paid to the cellular implications of 5-formyluracil in DNA. Here we review the present state of knowledge in this important area within research on oxidative DNA damage.
