Blocking arginine-modifying enzymes for aggressive ovarian and triple-negative breast cancer

Protein arginine methyltransferase inhibitors in treatment of high-grade serous ovarian cancer and triple-negative breast cancer

What this research studies

This project focuses on two hard-to-treat cancers—high-grade serous ovarian cancer and triple-negative breast cancer—and looks at drugs that block protein arginine methyltransferases (PRMTs), enzymes that are higher in many cancers. Scientists will use lab-grown cancer cells, genetic profiling, and animal models to see how PRMT blockers work and which drug combinations might make them more effective. The team combines large-scale drug pairing tests with cancer genome data to find combinations that could overcome resistance to single drugs. The goal is to identify mechanism-based combination treatments that could move into early human trials for patients with these cancers.

Who could benefit from this research

Good fit: Ideal candidates would be people with high-grade serous ovarian cancer or triple-negative breast cancer—especially tumors with DNA repair defects like BRCA mutations—if and when combined treatments reach clinical testing.

Not a fit: Patients without these cancer types or whose tumors lack the specific molecular features targeted by PRMT inhibitors are unlikely to benefit from this research in the near term.

Why it matters

Potential benefit: If successful, this work could lead to new combination therapies that improve outcomes for patients with aggressive ovarian and triple-negative breast cancers.

How similar studies have performed: Some PRMT inhibitors are already in early human trials but single-agent activity has been limited, so combining PRMT blockers with other drugs is a newer and less-tested approach.
