OBJECTIVE: To study the effects of Sparganium stoloni extract or Curcuma zedoaria extract combined with hyperthermia treatment on apoptosis, migration and invasion ability of colon cancer SW620 cells. METHODS: MTT assay was performed to detect the toxicity of S. stoloni extract (1.25, 2.5, 5, 7.5, 10 μg/mL) and C. zedoaria extract (5, 10, 15, 20, 25 μg/mL) to SW620 cells. The corresponding IC30 and IC50 were calculated. CFSE/PI double-staining method and Annexin V/PI double-staining+flow cytometry were used to investigate the effects of IC50 S. stoloni extract or IC50 C. zedoaria extract combined with hyperthermia treatment on the death and apoptotic rate of SW620 cells. Scratch test and Transwell invasion test were used to investigate the effects of IC30 S. stoloni extract or IC30 C. zedoaria extract combined with hyperthermia treatment on the migration and invasion ability of SW620 cells. RESULTS: IC30 and IC50 of S. stoloni extract were 3.24 μg/mL and 4.69 μg/mL; those of C. zedoaria extract were 11.27 μg/mL and 16.81 μg/mL. Compared with IC50 S. stoloni extract group or IC50 C. zedoaria extract group, death cells and apoptotic rate were increased significantly in IC50 S. stoloni extract+hyperthermia treatment group or IC50 C. zedoaria extract+hyperthermia treatment group (P<0.05). Compared with 0 h, healing distance of scratch test was not significantly narrowed in IC30 S. stoloni extract group, IC30 C. zedoaria extract group, IC30 S. stoloni extract+hyperthermia treatment group or IC30 C. zedoaria extract+hyperthermia treatment group. Compared with IC30 S. stoloni extract group or IC30 C. zedoaria extract group, the number of transmembrane cells decreased significantly in the invasive experiment in IC30 S. stoloni extract+hyperthermia treatment group or IC30 C. zedoaria extract+hyperthermia treatment group (P<0.05). CONCLUSIONS: Hyperthermia combination can significantly enhance the killing effect of S. stoloni extract or C. zedoaria extract on SW620 cells, and significantly improve their inhibitory effects on SW620 cell migration and invasion.
