Epigenetic targets in hormone‑resistant breast cancer

Epigenetic dependencies and vulnerabilities in endocrine-resistant breast cancer

NIH-funded research University of Miami School of Medicine · NIH-11289422

This work looks at whether blocking a specific epigenetic complex called CoREST‑SWI/SNF can stop or slow estrogen receptor–positive breast cancers that have stopped responding to hormone therapy.

What this research studies

From a patient's perspective, researchers will study how an epigenetic complex (CoREST together with SWI/SNF) helps some ER‑positive breast cancers become resistant to anti‑estrogen drugs. They will use tumor samples and laboratory models to map the molecular changes that drive resistance and identify points of vulnerability. The team will use genetic tools and drug-like inhibitors in cells and animal models to see if blocking this axis can halt tumor growth or restore sensitivity to hormone therapies. The goal is to point toward new treatments or drug targets for people with endocrine‑resistant disease.

Who could benefit from this research

Good fit: People with estrogen receptor–positive (ER+) breast cancer that has become resistant to anti‑estrogen therapies, especially those with recurrent or metastatic disease, would be most relevant to this research.

Not a fit: Patients with breast cancers that are ER‑negative or whose tumors rely on unrelated pathways are unlikely to benefit directly from these findings.

Why it matters

Potential benefit: If successful, this work could point to new drug targets that slow tumor growth or restore hormone sensitivity for patients with endocrine‑resistant ER+ breast cancer.

How similar studies have performed: Targeting epigenetic regulators has shown promise in laboratory models and some early clinical work, but applying this specific CoREST–SWI/SNF approach in patients is a newer direction.
