Corosolic acid increases the therapeutic effect of cisplatin on gastric cancer by regulating Gpx4-dependent ferroptosis.

ABSTRACT: Aim: Cisplatin serves as a primary chemotherapeutic agent in the treatment of gastric cancer (GC), but resistance to cisplatin-based chemotherapeutic regimens hampers its clinical application. Corosolic acid (CA), a natural triterpenoid, exhibits both anti-inflammatory and anti-cancer activities. However, the effect of CA on improving cisplatin resistance in GC remains unclear. The study primarily aimed to evaluate whether CA increases the therapeutic efficacy of cisplatin against GC and to reveal its underlying mechanism. Methods: Cisplatin and CA were used to treat GC cells or cisplatin-resistant AGS cells (AGS-CR), and then cell viability, apoptosis, and growth were assessed using Cell Counting Kit-8, TdT-mediated dUTP nick end labeling, and clone formation assays, respectively.
