Abstract

Patients with glioblastoma frequently suffer epileptic seizures and often require anticonvulsant therapy during the treatment course. The present study investigated four common antiepileptic drugs, perampanel, carbamazepine (CBZ), sodium valproate (VPA) and levetiracetam (LEV), which are expected to have antitumor effects, and determined the most beneficial drug for the treatment of malignant glioma by comparing antitumor effects such as inhibition of cell proliferation and suppression of migration and invasion (using Transwell assays). The inhibition of cell growth was investigated using six malignant glioma cell lines (A‑172, AM‑38, T98G, U‑138MG, U‑251MG and YH‑13). Significant inhibition of cell proliferation was observed in all six cell lines treated with perampanel, three cell lines treated with CBZ, four cell lines treated with VPA and two cell lines treated with LEV at the therapeutic blood concentration levels for the drugs to be used as antiepileptics. Further antitumor effects in combination with temozolomide were investigated using T98G and U‑251MG cell lines, and were confirmed in both cell lines with perampanel and in T98G cells with LEV, but not observed with CBZ and VPA. Cell migration was significantly suppressed in both T98G and U‑251MG cell lines with perampanel, but not with CBZ, VPA or LEV. To investigate the mechanisms by which perampanel suppresses the migration of malignant glioma cells, the expression of mRNA related to epithelial‑mesenchymal transition following perampanel treatment was analyzed using reverse transcription‑quantitative PCR in the T98G and U‑251MG cell lines. The expression of Rac1 and RhoA, which constitute the cytoskeleton that enhances cell motility, were reduced in both cell lines. Furthermore, the expression of the mesenchymal marker N‑cadherin, which promotes cell migration and infiltration, was decreased, but the expression of the epithelial marker E‑cadherin, which strengthens cell‑cell adhesion and reduces cell motility, was increased. Furthermore, the expression of matrix metalloproteinase‑2, a proteolytic enzyme, was reduced. These effects may reduce cell motility and increase adhesion between cells, suggesting that perampanel treatment suppressed cell migration. In conclusion, the present study suggests that perampanel may be more beneficial in terms of antitumor efficacy than other antiepileptic drugs for the treatment of malignant glioma.
