OCRF & Ovarian Cancer National Alliance are now one strong, united, inspiring voice!
Ovarian Cancer Research Fund (OCRF) and the Ovarian Cancer National Alliance (OCNA) have led the way in advocacy, research and support for patients and their families for over 22 years. As of January 2016, we are pleased to announce we are joining together to form Ovarian Cancer Research Fund Alliance (OCRFA), the largest global organization dedicated to advancing ovarian cancer research while supporting women and their families. Read the exciting news!

The Analysis of NEDD8-activating Enzyme Inhibitor MLN4924 on Ovarian Cancer

Project Summary

Ovarian cancer is the most deadly disease of the female reproductive tract and has historically been called the “silent killer.” Chemotherapy resistance and toxicity is one of the major barriers to cure ovarian cancer. Our study will test a novel strategy to sensitize ovarian cancer cells to a conventional chemotherapeutic drug. We found that ubiquitin-like protein Nedd8 plays an important role in DNA damage repair of ovarian cancer cells and the small molecule inhibitor of Nedd8 pathway, MLN4924 can suppress DNA damage repair. Therefore, MLN4924 can be used as the sensitizer for ovarian cancer chemotherapeutic drugs like cisplatin, which generates massive DNA damage to kill ovarian cancer cells. This study is of highly translational value by validating neddylation and its inhibitor MLN4924 as an attractive anti-cancer target and drug, respectively. If successful, translation of this novel finding to clinical trials is highly feasible. The completion of the pre-clinical studies described in this proposal will lead to the rational design of clinical trials including MLN4924 for the treatment of ovarian cancer with the final purpose of improving the quality and quantity of life of ovarian cancer patients, and converting this lethal cancer into a manageable disease.


Teng Ma, MD, PhD is a research fellow in the Department of Internal Medicine at the University of Michigan. After obtaining his medical degree from Shanxi Medical University in 2004, he finished his PhD at Peking University Health Science Center in China in 2009. After graduation, he joined Dr.Xiaochun Yu’s lab to study chromatin biology and DNA repair in tumorigenesis. His current research interest is to target the Neddylation pathway in ovarian cancer by using the small NEDD8 activating enzyme inhibitor MLN4924.
