8-Oxo-7,8-dihydroguanine (G(O), 8-hydroxyguanine) in DNA is one of the most important oxidatively damaged bases and causes G:C → T:A substitution mutations. The Werner syndrome protein (WRN) is a cancer-related RecQ DNA helicase and plays many roles in DNA replication and repair. To examine the relationships between G(O)-induced mutations and WRN, shuttle(More)
In DNA, 8-oxo-7,8-dihydroguanine (GO, 8-hydroxyguanine) is one of the most pivotal oxidatively damaged bases and induces G:C → T:A transversion mutations. DNA polymerase λ preferentially inserts dCTP opposite GO in vitro, and this error-free bypass function is considered to be important after A base removal from GO:A pairs by the MUTYH DNA glycosylase.
