NIH-funded research R37 grant

Investigating how changes in estrogen receptors can improve breast cancer treatment

Official title: Structural-Transcriptional Relationships that Improve Y537S Estrogen Receptor Antagonism

Funded at Loyola University Chicago · NIH-11062421 · Data updated 2026-11-12

This study is looking at how changes in a specific part of a protein related to breast cancer can help make treatments work better for patients whose cancer doesn't respond to usual hormone therapies, with the goal of finding new drugs that can more effectively target these tough-to-treat cancer cells.

Who could benefit from this research

Could help

Ideal candidates for this research are patients with hormone-resistant breast cancer, particularly those with the Y537S mutation in the estrogen receptor.

Less likely to help

Patients with non-hormone-responsive breast cancer or those without the Y537S mutation may not benefit from this research.

What this research studies

This research focuses on understanding how specific structural changes in the Y537S estrogen receptor alpha (ERα) can enhance the effectiveness of treatments for hormone-resistant breast cancer cells. By examining how these changes affect the receptor's ability to respond to antiestrogen therapies, the study aims to identify new drug candidates that can better target these resistant cancer cells. The approach involves using advanced techniques like x-ray crystallography to visualize how different drugs interact with the receptor, potentially leading to more effective treatment options for patients with advanced breast cancer.

Why it matters

Potential benefit: If successful, this research could lead to more effective therapies for patients with hormone-resistant breast cancer, improving survival rates and quality of life.

How similar studies have gone: Previous research has shown promise in targeting estrogen receptor mutations, suggesting that this approach could yield significant advancements in breast cancer treatment.
