Outline of Final Research Achievements

The study confirmed the data reproducibility on a detailed analysis of site-specific gene mutagenesis using TATAM system and revealed the relationship between gene function and scrupulous gene mutagenesis involving a single DNA adduct.
Mutations have been found universally in several types of oxidative DNA adducts, studied in the TATAM system. Moreover, data indicating that even DNA adducts believed to be non-mutagenic cause infrequent mutations have emerged from analyses conducted with increased numbers of cells.

Academic Significance and Societal Importance of the Research Achievements

本研究で使用したTATAM系は,社会的にも関心の高い放射線による閾値無し直線(Linear non-threshold; LNT)仮説,および化学物質等の遺伝毒性発がん物質には閾値が無いという議論を実験的に証明するために確立された。閾値の議論は,わずか1分子のDNA付加体であっても突然変異をもたらし,発がんに至る可能性が理論的にあることが発端となっており,それを今までは1分子という極低レベル暴露を動物実験などで実験的に証明が困難であったが,TATAM系はそれを可能にした。なお、本系は通常のDNA損傷で誘導される修復酵素群が正常と異なるため、さらなるデータ蓄積と研究が必要である。
