Research Abstract |
Photosensitizer, such as 5-Aminolevulinic acid(ALA), are used in photodynamic therapy and fluorescence-guided resection of malignant brain tumours due to its high cellular uptake in tumours. In the present study, the possible use of 5-ALA as a radiosensitizer for malignant brain tumours is examined in vitro using rat glioma cell lines(9L, C6). 5-ALA functions as a specific radiosensitizer for malignant gliomas. Intracellular 5-ALA-induced PpIX plays an important role in the production of ROS and the radiosensitizing effect under ionizing irradiation conditions.
