| Outline of Final Research Achievements |
The effect of cancer cell death increases depending on the ROS (Reactive Oxygen Species) in pancreatic cancer cells after anti-cancer therapy. DJ-1 binds to p53 and suppresses the transactivation activity of p53 depending on the p53-DNA binding affinity. The survival rate of pancreatic cancer patients who express high level of DJ-1 reduces by half. Therefore, cell death suppression by oxidative stress was predicted to work the malignant alteration of pancreatic cancer. We revealed the interaction between anticancer drug resistance and DJ-1. Furthermore, the relationship between anticancer drug resistance and DJ-1 or p53 was estimated by using the pancreatic cancer cells with different anticancer drug resistance.
