What this research studies

This project looks at proteins called cyclin C and the kinases CDK8 and CDK19 that control gene activity inside cells. The team studies these proteins in tumor samples, cell lines, and mouse models to see how they promote cancer. They will test small-molecule inhibitors in preclinical models to learn whether blocking CDK8/19 can slow tumor growth. The work aims to link laboratory findings to cancers that show high levels of these proteins so future treatments might be developed.

Who could benefit from this research

Good fit: People whose tumors show high levels of cyclin C, CDK8, or CDK19 — or cancers previously linked to CDK8/19 activity — would be the most relevant group for follow-up trials or therapies.

Not a fit: Patients whose cancers do not express these proteins or are driven by unrelated mechanisms are unlikely to benefit from therapies targeting CDK8/19.

Why it matters

Potential benefit: If successful, this work could point to new targeted drugs that slow tumor growth and improve outcomes for patients whose cancers depend on cyclin C/CDK8/19.

How similar studies have performed: Preclinical work, including cell-line and mouse xenograft studies, has shown that CDK8/19 inhibitors can reduce tumor growth, but clinical benefit in people has not yet been established.
