Abstract

The aim of the present study was to investigate the potential effect of hematoporphyrin monomethyl ether-sonodynamic therapy (HMME‑SDT) on MG‑63 osteosarcoma cells. The HMME concentration was kept constant at 20 µg/ml and the MG‑63 osteosarcoma cell line was exposed to ultrasound with an intensity of 1.0 W/cm2 for 30 sec. Cell cytotoxicity was quantified using an MTT assay 6 h after HMME‑SDT. The intracellular localization of HMME was imaged using inverted confocal laser scanning microscopy. Apoptosis was investigated using flow cytometry with Annexin V‑fluorescein isothiocyanate and propidium iodine staining. The cytotoxicity of HMME‑mediated sonodynamic action on MG‑63 cells was significantly higher than that of other treatments, including ultrasound alone, HMME alone and sham treatment. Flow cytometry demonstrated that HMME‑SDT action markedly enhanced the apoptotic rate of MG‑63 cells. The mechanisms of apoptosis were analyzed by measuring the protein expression of poly ADP‑ribose polymerase (PARP), cleaved PARP, procaspase‑3, cleaved caspase‑3 and cleaved caspase‑9. The data demonstrated that HMME‑SDT action markedly induced the apoptosis of MG‑63 cells.
