ABSTRACT
Management of gastric cancer is still challenging due to resistance to current chemotherapeutics and recurrent disease. Moreover, green- synthesized zinc oxide nanoparticles (ZnO-NPs) using natural resources are one of the most promising therapeutic agents for anticancer therapy. Here we report the facile green synthesis and characterization of ZnO-NPs from Teucrium polium (TP-ZnO-NP) herb extract and the anticancer activities of these nanoparticles on gastric cancer cells. Facile green synthesis of TP-ZnO-NP was achieved using zinc acetate dihydrate. For the characterization of TP-ZnO-NP, UV-vis spectroscopy, FTIR, SEM, XRD and EDX analyses were performed. Antiproliferative and anticancer activities of TP-ZnO-NP were explored using the HGC-27 gastric cancer cell line model. MTT cell viability and colony formation assays were used for the analysis of cell proliferation and migration. Wound healing assay was used to analyze the migration capacities of cells. Annexin V/PI double staining, DNA ladder assay, and Acridine orange/Ethidium bromide staining were performed to analyze the induction of apoptosis. qPCR was used to determine gene expression levels of apoptotic and epithelial to mesenchymal transition marker genes. The aqueous extract of TP served as both a reducing and capping agent for the successful biosynthesis of zinc oxide nanoparticles. Remarkably, synthesized TP-ZnO-NPs were found to have significant antiproliferative and anticancer activities on HGC-27 gastric cancer cells. Collectively, current data suggest that TP-ZnO-NP is a novel and promising anticancer agent for future therapeutic interventions in gastric cancer.
