Abstract

The invasion- and apoptosis-associated thromboxane synthase gene encoding an enzyme of the arachidonic acid pathway has been implicated in glioma progression. Furegrelate, a specific inhibitor of thromboxane synthase, blocks cell motility, induces apoptosis and increases sensitivity to drug induced apoptosis in human glioma cells in vitro. The impact of furegrelate on the sensitivity of human glioma cells to γ-irradiation was analyzed using colony formation assay in vitro and an orthotopic mouse model in vivo. Pre-treatment of glioma cells with furegrelate increases radiation sensitivity of cultured glioma cells. Treatment of experimental gliomas with suboptimal doses of radiation and furegrelate results in a significant decrease in tumor volumes compared to untreated controls. Thus, the specific thromboxane synthase inhibitor furegrelate increases death response induced by γ-radiation in glioma cells in vitro and sensitizes experimental gliomas to radiation treatment in vivo.
