BACKGROUND: Glioma is the most common primary tumor of the central nervous system, and accounted for about 70% of primary tumors. MATERIALS AND METHODS: In the study, antitumour activity and mechanism of paclitaxel was investigated. Different concentrations of paclitaxel (200, 300, 400 μmol/L) was treated in neuroglioma cellsU251. RESULTS: Paclitaxel significantly inhibited neuroglioma cells growth, and promoted its apoptosis. Paclitaxel can block tumour cells in the G2/M phase. In addition, apoptosis-related genes caspase-3 and bax expressions were increased after paclitaxel treatment. CONCLUSION: Our work indicated that paclitaxel displayed strong anti-tumour activity.
