Abstract: Glioblastoma is one of the most common malignant tumors in the nervous system in both adult and pediatric patients. Studies suggest that abnormal activation of receptor tyrosine kinases contributes to pathological development of glioblastoma. However, current therapies targeting tyrosine kinase receptors have poor therapeutic outcomes. Here, we examined anticancer effects of ponatinib, a multi-targeted tyrosine kinase inhibitor, on glioblastoma cells both in the U87MG cell line and in the mouse xenograft model. We showed that ponatinib treatment reduced cell viability and induced cell apoptosis in a dose-dependent manner in U87MG cells. In addition, ponatinib suppressed migration and invasion of U87MG cells effectively. Furthermore, ponatinib-treated tumors showed an obvious reduction of tumor volume and an increase of apoptosis as compared with vehicle-treated tumors in the mouse xenograft model. These findings support a potential application of ponatinib as a chemotherapeutic option against glioblastoma cells.
