NIH-funded research R03 grant

Targeting cancer cells lacking the RB1 gene

Official title: Combined targeting of synthetic lethal partners in RB1-deficient cells

Funded at University of Pittsburgh at Pittsburgh · NIH-11004363 · Data updated 2026-11-12

This study is exploring a new way to treat certain cancers, like retinoblastomas and breast cancers, that have a specific gene mutation, by targeting two genes at once to help kill the cancer cells, and it's designed for patients with these RB1-related tumors.

Who could benefit from this research

Could help

Ideal candidates for this research are patients diagnosed with cancers that have mutations in the RB1 gene, such as retinoblastomas, small cell lung cancers, and triple-negative breast cancers.

Less likely to help

Patients whose cancers do not involve RB1 mutations or those with other unrelated cancer types may not benefit from this research.

What this research studies

This research investigates a novel approach to treat cancers that have mutations in the RB1 tumor suppressor gene, which is commonly found in various tumors such as retinoblastomas and breast cancers. The study focuses on synthetic lethality, where two genes are targeted simultaneously to kill cancer cells that would survive if only one gene were affected. By identifying and targeting specific gene interactions, the research aims to develop effective therapies for patients with RB1-deficient tumors. The methodology involves genetic screening and testing in human cancer cell lines and patient samples to validate potential treatment targets.

Why it matters

Potential benefit: If successful, this research could lead to new targeted therapies for patients with RB1-deficient cancers, improving treatment outcomes.

How similar studies have gone: Previous research has shown promise in targeting synthetic lethal interactions in cancer treatment, indicating potential for success in this novel approach.
