Outline of Final Research Achievements

Chemoresistance of ovarian cancer poses a major obstacle to the successful management of this devastating disease. We found that specific JNK inhibitor, SP600125, treatment sensitizes cytotoxic drugs such as paclitaxel and cisplatin. This result suggests that JNK and its signal transduction might have a key role in the resistance of ovarian cancer cells to chemotherapy.
Additionally, we examined whether AS602801, a newly developed JNK inhibitor as the therapeutic agent for inflammatory endometriosis and which is revealed the safety in the Phase 2 clinical study, has the anti-cancer effects and inhibiting cancer stem cells in vitro and in vivo. AS602801 has modest cytotoxic activity on cancer stem cells in vitro and clearly inhibits tumor-initiating capacity in vivo. These findings suggest that AS602801 is a promising anti-cancer stem cell agent.
