| Research Abstract |
The cell cycle dependent base excision repair of methylated base damage was investigated using a novel assay system for the detection of intranuclear abasic sites. In polβ-KO MEF, the removal of methylated bases was significantly slower than wild type especially in G1 phase, suggesting the lack suppressed the glycosylase activity to bypass the accumulation of hazardous intermediate, AP sites.
