What this research studies

If I or someone I love had a rare adrenal or liver tumor caused by overactive PKA, this team is trying to find treatments that stop the cancer's abnormal protein-making machinery instead of blocking PKA itself. They study tumor samples and lab models to map how mutant PKA rewires signaling and increases mRNA translation. The researchers then test candidate drugs that target downstream factors like the RNA helicase eIF4A to see if tumors stop growing. The aim is to find more selective, better-tolerated options for patients with these rare cancers.

Who could benefit from this research

Good fit: Ideal candidates would be people with rare adrenal or hepatic tumors known or suspected to have activating PKA (PKAc) mutations who could donate samples or join future clinical trials.

Not a fit: Patients whose tumors are not driven by PKA signaling or who need immediate standard-of-care treatment may not benefit from these specific targeted approaches.

Why it matters

Potential benefit: If successful, this approach could produce new targeted therapies that shrink or slow PKA-driven adrenal and liver tumors with fewer side effects than broad PKA inhibitors.

How similar studies have performed: Preclinical studies have shown that targeting translation factors like eIF4A can slow tumor growth, but clinical success in patients remains limited and this strategy is still early-stage.
