In vivo: Nodularin-R Enhances Abiraterone's Effectiveness Against Castration-Resistant Prostate Cancer

another door opens, hopefully a good one…

Researchers found that high expression of the PPP1CA gene is linked to a worse prognosis for patients. They discovered that silencing PPP1CA made cancer cells more susceptible to abiraterone, while overexpressing it had the opposite effect. This suggests that PPP1CA plays a crucial role in protecting cancer cells from abiraterone's effects. The study also identified nodularin-R, a natural product, as a potential inhibitor of PPP1CA. Combining nodularin-R with abiraterone resulted in synergistic inhibition of resistant cancer cells both in vitro and in vivo, indicating that nodularin-R might help overcome abiraterone resistance in CRPC.
