ABSTRACT
The present study investigated the underlying molecular mechanism by which Buthus martensii Karsch chlorotoxin (BmK CT) inhibits the invasion and metastasis of glioma cells and the possibility of 131Ilabeled BmK CT (131IBmK CT) as a novel targeted agent for the treatment of glioma. The impact of BmK CT with and without 131I radiolabeling on the invasion and metastasis of glioma cells in vitro was studied. Cell viability was assessed using Cell Counting Kit8 and plate colony formation assays in order to confirm the cytotoxicity of BmK CT and 131IBmK CT at different concentrations. Transwell invasion and woundhealing assays were conducted in order to investigate the inhibitory effects BmK CT and 131IBmK CT on cell migration and invasion. Furthermore, western blotting, ELISA immunofluorescence and a gelatin zymography assay were performed to evaluate changes in the protein expression levels of glioma cells following treatment with BmK CT or 131IBmK CT. The results indicated that BmK CT inhibits the invasion and metastasis of glioma cells via regulation of tissue inhibitor of metalloproteinase2 expression and that 131IBmK CT has the potential to be a novel targeted therapeutic drug for glioma.
