Glioblastoma is the most common type of malignant human brain tumor. Currently available chemotherapies for glioblastoma focus on targeting tyrosine kinases. However, the existing inhibitors of tyrosine kinases have not produced the therapeutic outcomes that were anticipated. In order to investigate the viability alternative chemotherapeutic agents in this disease, the present study examined the anticancer effects of tyrphostin AG 1296, focusing on its involvement in apoptosis in glioblastoma cells. The study aimed to identify whether tyrphostin AG 1296 affects glioblastoma cell growth by inducing cell apoptosis. To achieve this, cell viability, propidium iodide analysis and cell invasion assay were used to measure cell growth, cell apoptosis and cell migration of human glioblastoma cells. The results showed that tyrphostin AG 1296 treatment reduced cell viability and suppressed migration of human glioblastoma cells. It was also demonstrated that tyrphostin AG 1296 induced cell apoptosis in vitro. Finally, tyrphostin AG 1296 was also shown to significantly inhibit the growth of glioblastoma cells and to increase tumor cell apoptosis in vivo. These findings suggest that tyrphostin AG 1296 induces apoptosis, thereby reducing cell viability and capacity for migration of glioblastoma cells.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
