Cyclooxygenase(COX)-2 of astrocytic tumors was studied by immunohistochemistry. COX-2 was expressed in 8 of 12(75%) glioblastoma multiforme, 1 of 7(14%) anaplastic astrocytoma, but none in astrocytoma. COX-2 was detected by an immnoblotting in 2 of 9 human glioblastoma cell lines(KNS42 and U138). In glioblastoma cell lines, NS398 and Etodolac inhibited cell proliferation and induced apoptosis. The result showed that COX-2 expression may be related with histological grades and COX-2 inhibitors will be one of promising therapeutic tools in human astrocytic tumors.
