Blocking eIF4A1 to overcome drug-resistant triple-negative breast cancer

Targeting eIF4A1 in drug-resistant breast cancer stem-like cells

NIH-funded research University of Toledo Health Sci Campus · NIH-11142442

This project tests whether stopping a protein called eIF4A1 can weaken drug-resistant breast cancer stem cells in people with aggressive triple-negative breast cancer.

What this research studies

If I have aggressive triple-negative breast cancer, the team will study how eIF4A1 helps cancer stem-like cells survive and pump out chemotherapy drugs. They will use laboratory models and likely analyze tumor samples to see how eIF4A1 controls key stem-cell genes and drug transport proteins. The researchers will test molecules that block eIF4A1 to see if those treatments make resistant cells more sensitive to standard chemotherapy. The goal is to find approaches that could prevent relapse by reducing the drug-resistant cells that drive metastasis.

Who could benefit from this research

Good fit: People with triple-negative breast cancer, especially those with metastatic disease or tumors that have become resistant to chemotherapy, would be most relevant to this research.

Not a fit: Patients with other breast cancer subtypes or tumors that do not show eIF4A1- or ABC transporter–driven resistance are less likely to benefit from this approach.

Why it matters

Potential benefit: If successful, this work could make chemotherapy more effective and lower the chance of relapse in metastatic or treatment-resistant triple-negative breast cancer.

How similar studies have performed: Preclinical studies targeting translation factors like eIF4A1 and related pathways have shown promise in lab models, but clinical evidence in patients remains limited and experimental.
