Abstract In this study, ultrasonically driven biosynthesis of zinc oxide nanoparticles (ZnO NPs) using Swietenia macrophylla seed ethyl acetate fraction (SMEAF) has been reported. X-ray powder diffraction (XRD) and Fourier-transform infrared spectroscopy (FTIR) analyses confirmed the presence of a pure hexagonal wurtzite structure of ZnO. Field emission scanning electron microscope images revealed the formation of uniquely identifiable uniform rice-shaped biologically synthesized ZnOSMEAF particles. The particle sizes of the biosynthesized NPs ranged from 262 to 311 nm. The underlying mechanisms for the biosynthesis of ZnOSMEAF under ultrasound have been proposed based on FTIR and XRD results. The anticancer activity of the as-prepared ZnOSMEAF was investigated against HCT-116 human colon cancer cell lines via methyl thiazolyl tetrazolium assay. ZnOSMEAF exhibited significant anticancer activity against colon cancer cells with higher potency than ZnO particles prepared using the chemical method and SMEAF alone. Exposure of HCT-116 colon cancer cells to ZnOSMEAF promoted a remarkable reduction in cell viability in all the tested concentrations. This study suggests that green sonochemically induced ZnO NPs using medicinal plant extract could be a potential anticancer agent for biomedical applications.

Colorectal cancer is the third most commonly diagnosed cancer in the word. Carnosine is an endogenous dipeptide found in vertebrate skeletal muscles. It is known to have anti-fatigue, antioxidative, antihypertensive, antidiabetic, and cancer inhibiting effects. However, little research has been done regarding its influence on the metastasis of colon cancer. This study cultivated HCT-116 human colon cancer cells as a test model in order to investigate the impact of carnosine on the migration and invasion of human colon cancer cells. The results showed that 48-hour treatments of HCT-116 cells with 0.5, 1, or 5 mM carnosine each significantly inhibited the migration ability of the cells (P < 0.05). The 48-hour treatments with 0.5, 1, or 5 mM carnosine were also found to significantly reduce MMP-9 activity (P < 0.05), but not MMP-2 expression. Furthermore, when HCT-116 cells treated with 1 or 5 mM carnosine, invasion ability are significantly decreased and significantly increased E-cadherin expression (P < 0.05). On the other hand, the protein of TIMP-1, an inhibitor of MMP-9, is signification increased after 1 or 5 mM carnosine treatment (P<0.05). In addition, the u-PA protein level are significantly decreased after carnosine treatment. The results indicate that carnosine can regulate the migration and invasion by regulating MMPs and its regulator molecular expression in HCT-116 cells.
