We investigated the function of the interaction between WRN (Werner syndrome gene product) and Ku70 and between WRN and DNA-PKcs, which are components of the DNA-PKcs/Ku70/Ku80 complex, by generating KU70(-/-)/WRN(-/-) and DNA-PKcs(-/-/-)/WRN(-/-) double-gene knockout chicken DT40 cells. When treated with camptothecin (CPT), an inhibitor of DNA(More)
Bloom's syndrome (BS), which is caused by mutations in the BLM gene, is characterized by a predisposition to a wide variety of cancers. BS cells exhibit elevated frequencies of sister chromatid exchanges (SCEs), interchanges between homologous chromosomes (mitotic chiasmata), and sensitivity to several DNA-damaging agents. To address the mechanism that(More)
Bloom's syndrome (BS) is an autosomal disorder characterized by predisposition to a wide variety of cancers. The gene product whose mutation leads to BS is the RecQ family helicase BLM, which forms a complex with DNA topoisomerase IIIalpha (Top3alpha). However, the physiological relevance of the interaction between BLM and Top3alpha within the cell remains(More)
As Japan becomes a super-aging society, presentation of the best ways to provide medical care for the elderly, and the direction of that care, are important national issues. Elderly people have multi-morbidity with numerous medical conditions and use many medical resources for complex treatment patterns. This increases the likelihood of inappropriate(More)
