The expression level of metabolitic enzyme (CYP1A1, CYP1B1) and its correlation with cell differentiation /apoptosis were studied as well. The influence of resveratrol in cell cycle was determined with FCM. Results 1 Resveratrol not only suppresses the growth of medulloblastoma cells in a dose and time related fashion but also induces cell differentiation and apoptosis. Resveratrol promotes differention of UW228-1,-2 cells to forward glia, UW228-3 and Med-3 cells to neuron. A treatment of resveratrol in the concentration of 100μM for 48hrs comit most of cells die of apoptosis. 2 Among the four cell lines Fas and Caspase-3 were constantly expessed, whereas FasL was absent irrespective to the drug treatment. 3 ICC, RT-PCR, Western-blot hybridization and EROD enzymatic activity assay demonstrated that expression of CYP1A1 is different after treatment with resveratrol in four cell lines, up-regulated in three UW228 cell lines in a dose dependent manner but down-regulated in Med-3 cells. Suppressive effect of resveratrol on CYP1B1 expression is the same among four medulloblatoma cell lines. 4 Cell cycle distribution of UW228-3 was greatly changed after treatment.

结果：1、白藜芦醇以时间和剂量依赖性方式抑制髓母细胞瘤细胞生长，同时促进细胞的分化和凋亡：白藜芦醇促使UW228-1、-2靶细胞向神经胶质细胞方向成熟分化，UW228-3、Med-3细胞向神经元细胞方向成熟分化，以100μM作用48小时效果显著；2、四个细胞系均有Fas和Caspase-3表达，但无Fas-L基因表达和蛋白活性产生，因此难以形成Fas相关性死亡通路；3、白藜芦醇处理前后CYP1A1基因的表达在各细胞系略有不同：UW228-1，-2，-3三个细胞系白藜芦醇以剂量相关性方式上调CYP1A1的表达，而Med-3细胞系，白藜芦醇却抑制CYP1A1的表达；四个细胞系在白藜芦醇处理后CYP1B1的表达均受到抑制；4、UW228-3细胞系经白藜芦醇作用后细胞周期有较大改变，表现在G0/G1期在整个细胞周期中所占的比例增加，而其它时期则相应减少。
