Abstract

Background: Curzerene, a bioactive compound from Curcuma zedoaria, exhibits Anticancer effects, but its role in gastric precancerous lesions remains poorly understood. This study investigates the potential of Curzerene in inhibiting gastric precancerous lesions progression by regulating the long non-coding RNA (LncRNA) AFAP1-AS1 and the Hippo/YAP signaling pathway.

Methods: In vitro, a gastric precancerous cell model (MC cells) was established by treating GES-1 cells with MNNG. The effects of Curzerene on cell proliferation, migration, and EMT were assessed using CCK-8, scratch assays, RT-PCR, and Western blot. In vivo, a gastric precancerous mouse model was induced by MNU, and the therapeutic effects of Curzerene (14 mg/kg and 28 mg/kg) were evaluated through histological and molecular analysis.

Results: Curzerene treatment significantly inhibited MC cell proliferation, migration, and EMT, downregulating LncRNA AFAP1-AS1 and YAP while upregulating E-cadherin and downregulating N-Cadherin. In vivo, Curzerene alleviated gastric mucosal damage, reduced Cancer markers (P53 and CD133), and improved histopathology. Transcriptomic analysis identified the Hippo/YAP pathway as a key mediator of Curzerene's effects. YAP activation reversed Curzerene's inhibitory effects on EMT, confirming the involvement of this pathway.

Conclusion: Curzerene effectively inhibits gastric precancerous lesion progression by targeting the YAP signaling and the following LncRNA AFAP1-AS1 to suppress EMT. These findings suggest Curzerene's novel potential as a promising therapeutic agent for early intervention and prevention of gastric Cancer.
