Blocking APOBEC3A to prevent drug-resistant bladder cancer

Targeting APOBEC3A-induced genetic heterogeneity and drug resistance in bladder cancer

NIH-funded research Weill Medical Coll of Cornell Univ · NIH-11161623

This work tries to stop a gene called APOBEC3A from causing genetic changes that make bladder cancer resist treatment, aiming to help people with advanced urothelial carcinoma.

What this research studies

Researchers will define how APOBEC3A creates genetic diversity within bladder tumors that leads to resistant cancer cells. They will use lab-grown cancer cell lines and organoids made from patient tumors to trace the mutations APOBEC3A causes and to find weaknesses those mutations create. Using these models, the team will test strategies to block APOBEC3A activity or selectively eliminate APOBEC3A-active tumor cells. The goal is to develop precision approaches that can be combined with current therapies to reduce relapse from drug-resistant clones.

Who could benefit from this research

Good fit: Ideal candidates are people with advanced or metastatic urothelial carcinoma, especially those whose tumors show signs of APOBEC3A activity or who have developed resistance to systemic treatments.

Not a fit: Patients with early-stage bladder cancer, tumors without APOBEC3A activity, or other cancer types may not receive direct benefit from this work in the near term.

Why it matters

Potential benefit: If successful, this could reduce the emergence of treatment-resistant bladder cancer cells and help patients stay responsive to therapy longer.

How similar studies have performed: Prior laboratory studies link APOBEC enzymes to mutation-driven resistance, but directly targeting APOBEC3A is largely novel and has not yet produced established clinical treatments.
