Who could benefit from this research

Could help

Ideal candidates are adults with hormone receptor–positive breast cancer, especially those with tumors overexpressing BCL2, who may benefit from combined BCL2 inhibition and radiation.

Less likely to help

Patients whose tumors do not overexpress BCL2 or who cannot receive radiation may have limited or no benefit.

What this research studies

The project studies how BCL2, a protein that helps cancer cells survive, shapes the immune environment in HR+ breast cancer and how it changes when radiation is given. It uses human and mouse tissues to see if reducing BCL2 can make the immune system respond more strongly to treatment. The researchers also test venetoclax, a BCL2 inhibitor, in combination with radiation in mouse models to see if this combo enhances anti-tumor effects. A novel model that mimics features of human HR+ breast cancer will help translate findings toward potential patient trials.

Why it matters

Potential benefit: If successful, the approach could lead to more effective use of radiation by overcoming immune resistance in HR+ breast cancer.

How similar studies have gone: Prior work shows BCL2 inhibitors are already approved for other cancers and may synergize with therapies that stimulate the immune response.
