Official title: Protein arginine methyltransferase inhibitors in treatment of high-grade serous ovarian cancer and triple-negative breast cancer
Funded at University of Pennsylvania · NIH-11383146 · Data updated 2026-11-12
A cancer research project tests whether drugs that block arginine methylation can help treat high-grade serous ovarian cancer and triple-negative breast cancer.

Who could benefit from this research
✓Could help
Patients with high-grade serous ovarian cancer or triple-negative breast cancer who eligible for future targeted therapy studies.
✕Less likely to help
Patients without these cancers or those not suitable for targeted therapy combinations may not benefit.
What this research studies
This project looks at how blocking protein arginine methyltransferases (PRMTs) could complement existing therapies for ovarian and breast cancers. It combines large-scale drug screening and cancer genomics to identify effective combination strategies with PRMT inhibitors. The goal is to understand the mechanisms by which PRMT inhibitors work in these cancers and to translate that knowledge into better treatment options for patients. The work is led by the University of Pennsylvania and aims to move findings toward clinical relevance in conditions with poor prognosis.
Why it matters
Potential benefit: If successful, patients with HGSOCO and TNBC could have new combination therapies that improve outcomes.
How similar studies have gone: Other PRMT inhibitor studies have shown potential, but combination strategies in these cancers are still being explored.
