Curcumin-encapsulated fish gelatin-based microparticles from microfluidic electrospray for postoperative gastric cancer treatment.

| Abstract |
Gastric cancer is the fifth most frequently diagnosed malignant neoplasm and the third leading cause of cancer-related mortality. Nevertheless, the therapeutic efficacy of conventional surgical and chemotherapeutic interventions in clinical practice is often unsatisfactory. Curcumin (Cur) has shown promise as a therapeutic agent in prior studies. However, its progress in this context has been impeded by challenges including low solubility, instability in aqueous environments, and rapid metabolism. In this study, we develop methacrylate fish gelatin (FGMA) hydrogel microparticles (FGMPs@Cur) encapsulating Cur via microfluidic electrospray technology for postoperative comprehensive treatment of gastric cancer. Comprehensive characterizations and analyses were conducted to assess the cytotoxicity against gastric cancer cells and potential tissue reparative effects of FGMPs@Cur. In vitro experiments revealed that FGMPs@Cur exhibited a remarkable cytotoxic effect on nearly 80 % of gastric cancer cells while maintaining at least 95 % viability of normal cells in cell compatibility tests. In vivo results demonstrated that FGMPs@Cur significantly reduced tumor volume to 47 % of the control group, and notable tissue regeneration was observed at the surgical site. These properties indicated that such a hydrogel microparticle system is a promising candidate for postoperative gastric cancer treatment in practical application.
