Who could benefit from this research

Could help

The eventual candidates would be patients (typically children and adolescents) whose tumors are driven by the PAX3‑FOXO1 fusion.

Less likely to help

Patients whose tumors lack the PAX3‑FOXO1 fusion, or people with other cancer types, are unlikely to benefit directly from these specific approaches.

What this research studies

This project seeks small molecules that bind the PAX3‑FOXO1 fusion protein or its close partners to stop the fusion from driving tumor growth. The team will run high‑throughput screening, use chemoproteomics and interaction mapping to find where compounds bind, and study how hits change gene activity and chromatin in lab models. Medicinal chemistry and pharmacology work will optimize promising compounds and test them in preclinical models as a step toward therapies for patients.

Why it matters

Potential benefit: If successful, the work could produce targeted drugs that slow or stop tumor growth in children with PAX3‑FOXO1 fusion‑positive alveolar rhabdomyosarcoma.

How similar studies have gone: Directly targeting oncogenic fusion transcription factors with small molecules is relatively new and largely preclinical, though chemoproteomic and degrader strategies have shown promising lab and animal results.
