| Outline of Final Research Achievements |
Chromosomal stability is ensured by the accurate DNA replication and the equal segregation of duplicated chromosomes. In tumors, such mechanism is often disrupted and chromosomal instability, which is represented as high mutation frequency and abnormal number of chromosomes, emerges. In our previous study, we reported that the colorectal cancer patients who exhibited higher expression of chromosomal stability factor FANCJ in their tumors tended to be poor prognosis and less effective with 5-FU-based chemotherapy (Nakanishi et al. Ann Surg Oncol 2012). In this project, we drugged the underlying molecular mechanism of the association between FANCJ expression and 5-FU resistance experimentally and found that the physical interaction between FANCJ and key partners are critical.
