Research Abstract

FANCJ is not only one of Fanconi anemia genes but also functions in cooperation with tumor suppressor gene products such as BRCA1 and MLH1. We found that(1) FANCJ deficient cells displayed a characteristic genomic instability phenotype. Moreover, we obtained clinical data that suggest that FANCJ affects anti-tumor effect of 5-FU in colorectal cancer patients.
