Abstract

Purpose: Chemotherapy-induced nausea and vomiting (CINV) is a common gastrointestinal side effect in cancer treatment. 6-gingerol, a bioactive component of ginger, demonstrates efficacy in attenuating CINV. This study aimed to explore the effects of 6-gingerol on inhibiting ferroptosis and to clarify its potential antiemetic mechanisms in a cisplatin-induced rat pica model.

Methods: We established the rat pica model by intraperitoneal injection of cisplatin (6 mg/kg). The histopathological damage in gastrointestinal (GI) tissues was assessed by hematoxylin-eosin staining. The levels of serum IL-6, IL-1β, TNF-α, and hepcidin were measured by ELISA. The occurrence of ferroptosis was confirmed by measuring the levels of ROS, GSH, SOD, MDA, and iron in GI tissues. Furthermore, iron deposition was visualized with Perls + DAB staining, and the lipid peroxidation product 4-HNE was detected via immunohistochemistry. The expression levels of iron homeostasis-related proteins in GI tissues were examined by western blotting.

Results: The results showed that 6-gingerol improved pica behavior and mitigated GI inflammation in cisplatin-treated rats. Additionally, 6-gingerol mitigated oxidative stress, lipid peroxidation, and reduced iron accumulation. Molecular docking analysis showed that iron homeostasis-related proteins (TfR1, DMT1, ferritin, Fpn, and hepcidin) might be the potential regulatory targets of 6-gingerol. Mechanistically, 6-gingerol restored iron homeostasis by downregulating the expression levels of TfR1 and DMT1 to reduce iron uptake and transport, and upregulating the expression levels of ferritin and Fpn to enhance iron storage and export.

Conclusion: Overall, this study indicates that regulating iron homeostasis to inhibit ferroptosis is related to the therapeutic effect of 6-gingerol against CINV.
