Enzyme‑activated peptides to target drug‑resistant triple‑negative breast cancer

New approach based on enzyme stimulating of peptides for targeting drug resistance breast cancers

NIH-funded research University of North Texas · NIH-11373950

This project uses enzyme‑activated peptides that form tiny fibers inside triple‑negative and drug‑resistant breast cancer cells to help kill them.

What this research studies

Researchers design short peptides that are changed by an enzyme called EYA, which is active in some triple‑negative breast cancer cells; when EYA removes a phosphate group, the peptides self‑assemble into nanofibers inside the cancer cells. Those nanofibers are intended to trigger controlled cell death in tumors that do not respond to hormone or HER2‑targeted therapies. Early lab work has tested these peptides in cell cultures, including 3D models that better mimic tumors, and showed promising conversion and self‑assembly. The team will refine peptide sequences and measure how selectively the approach kills cancer cells versus normal cells to guide future development.

Who could benefit from this research

Good fit: Adults with triple‑negative or drug‑resistant breast cancer whose tumors do not respond to hormonal or HER2‑directed therapies would be the most relevant patients for future trials or sample donations.

Not a fit: People with hormone receptor‑positive or HER2‑positive breast cancers that respond to standard treatments, or anyone seeking an immediate approved therapy, are unlikely to benefit directly from this early laboratory work.

Why it matters

Potential benefit: If successful, this could lead to a new targeted therapy for triple‑negative or drug‑resistant breast cancers that currently lack effective molecular treatments.

How similar studies have performed: Related enzyme‑triggered, self‑assembling peptide approaches have shown promise in laboratory models but remain early‑stage and have not yet produced approved treatments.
