Targeting PRMT5 to improve treatment for triple-negative breast cancer

Characterizing and targeting PRMT5 in autophagy for cancer treatment

['FUNDING_R01'] · CASE WESTERN RESERVE UNIVERSITY · NIH-11416217

This project seeks to help people with triple-negative breast cancer by blocking a protein called PRMT5 and changing cell 'self-cleaning' (autophagy) so treatments work better.

What this research studies

If you or a loved one has triple-negative breast cancer, this project focuses on a protein called PRMT5 that is often high in these tumors and linked to worse outcomes. Researchers will use TNBC cell lines and lab models to study how PRMT5 is controlled (including modification by TRAF6) and how it suppresses autophagy. They will test PRMT5-blocking drugs alone and together with drugs that affect autophagy to find combinations that kill TNBC cells more effectively. The work aims to produce lab data that could guide future clinical trials for people with TNBC.

Who could benefit from this research

Good fit: Ideal candidates for future clinical work would be people with triple-negative breast cancer, particularly those whose tumors show high PRMT5 levels.

Not a fit: People with non–triple-negative breast cancer subtypes or tumors lacking PRMT5 overexpression are less likely to benefit from this specific approach.

Why it matters

Potential benefit: If successful, this work could lead to new combination therapies that make PRMT5 inhibitors more effective for people with triple-negative breast cancer.

How similar studies have performed: PRMT5 inhibitors are already in clinical trials and show early promise, but combining PRMT5 inhibition with autophagy-targeting therapies is a novel approach that has not been fully tested clinically.
