Abstract:
Glioblastoma (GBM), the most aggressive form of brain cancer, is characterized by rapid growth and resistance to conventional therapies. Current treatments offer limited effectiveness, leading to poor survival rates and the need for novel therapeutic strategies. Arylquin 1 has emerged as a potential therapeutic candidate because of its unique mechanism of inducing apoptosis in cancer cells without affecting normal cells. This study investigated the efficacy of Arylquin 1 against GBM using the GBM8401 and A172 cells by assessing its dose-dependent cytotoxicity, apoptosis induction, and synergy with radiotherapy. In vitro assays demonstrated a significant reduction in cell viability and increased apoptosis, particularly at high concentrations of Arylquin 1. Migration and invasion analyses revealed notable inhibition of cellular motility. In vivo experiments on NU/NU nude mice with intracranially implanted GBM cells revealed that Arylquin 1 substantially reduced tumor growth, an effect magnified by concurrent radiotherapy. These findings indicate that by promoting apoptosis and enhancing radiosensitivity, Arylquin 1 is a potent therapeutic option for GBM treatment.
