Investigating how And-1 affects resistance to breast cancer treatment

The role of And-1 in R-loop and endocrine resistance in breast cancer

['FUNDING_R01'] · GEORGE WASHINGTON UNIVERSITY · NIH-11044612

This study is looking at a protein called And-1 to see how it affects the way some breast cancer patients stop responding to a common treatment, and it hopes to find new ways to help those patients by testing new drugs that target And-1.

What this research studies

This research focuses on understanding the role of a protein called And-1 in the development of resistance to aromatase inhibitors, a common treatment for estrogen receptor-positive breast cancer. The study aims to explore how And-1 influences the resolution of R-loops, which are structures that can disrupt gene expression. By utilizing both laboratory experiments and patient-derived models, the researchers will test new inhibitors targeting And-1 to potentially overcome treatment resistance in patients. This approach could lead to more effective therapies for those who have developed resistance to current treatments.

Who could benefit from this research

Good fit: Ideal candidates for this research are breast cancer patients with estrogen receptor-positive tumors who have developed resistance to aromatase inhibitors.

Not a fit: Patients with breast cancer who have not been treated with aromatase inhibitors or those with other types of breast cancer may not benefit from this research.

Why it matters

Potential benefit: If successful, this research could provide new treatment options for breast cancer patients who have become resistant to aromatase inhibitors.

How similar studies have performed: Previous studies have shown promise in targeting similar mechanisms in cancer therapy, indicating potential for success with this novel approach.
