What this research studies

This program develops chemical probes and drug candidates that tag disease proteins for destruction rather than just blocking them. Scientists will design DNA-based targeting pieces and small molecules called PROTACs to guide the cell’s own protein-removal machinery to EBNA1 (an Epstein-Barr virus protein) and to PARP1 (a cancer-linked protein). Work uses laboratory assays, biochemical screening, medicinal chemistry, and cancer cell models to test which compounds selectively degrade the target proteins and kill tumor cells. Teams will compare protein degraders to existing enzyme-blocking drugs like olaparib to see differences in activity and potential combinations with other cancer drugs.

Who could benefit from this research

Good fit: People with Epstein-Barr virus–positive cancers or tumors known to respond to PARP-targeting approaches would be the most relevant candidates for future trials.

Not a fit: Patients whose tumors are not driven by EBV or who lack PARP-related vulnerabilities are unlikely to benefit from these specific approaches.

Why it matters

Potential benefit: If successful, this could lead to new targeted therapies that more effectively kill tumor cells by removing key cancer proteins.

How similar studies have performed: PARP enzyme inhibitors like olaparib are already used in patients, while protein-degrading PROTACs are a newer strategy with promising preclinical results but limited clinical testing so far.
