Updated project metadata. High-grade serous ovarian cancer (HGSOC) is the deadliest gynecologic malignancy in women.The lack of effective second line therapeutics remains a substantial challenge for BRCA-1/2 wildtype HGSOC patients, and contributes to poor survival rates due to drug resistance. There is a striking need to elucidate and implement new and alternative treatment options for patients with HGSOC. Histone Deacetylases (HDACs) are promising targets in HGSOC treat-ment, however, the mechanism and efficacy of HDAC inhibitors is understudied in HGSOC. In order to consider HDACs as a treatment target, we need to better understand how they are functioning within HGSOC. This includes elucidating HDAC6 protein-protein interactions. In this study, we carried out substrate trapping to elucidate HDAC6-specific interactors in the context of BRCA-1/2 wildtype HGSOC
