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。

Neural cell adhesion molecule L1, discovered in the 80s, is one of the matters that can promote nerve regeneration. It can mediate the interaction of cell-to-cell and cell-to-matrix, take great efforts on neurite outgrowth and fasciculation, migration of neural cells, formation of the myelin, structure of neural trace, transmembrane signal transduction, inhibiting apoptosis of neural cells, even on immune system and formation of the tumor. Li is discovered on the mouse's Cerebellar membrane primarily. Thereafter, it also is found in post- mitotic neurons, pre- and non-myelinating Schwann cells and so on.

神经细胞粘附分子L1（L1）是80年代发现的具有促进神经再生作用的物质，它能介导神经细胞与神经细胞之间的粘附，在神经轴突的生长、聚集，神经细胞的转移，纤维髓鞘的形成，神经通路的构建及信号的转导，抑制神经细胞的凋亡甚至在免疫系统、肿瘤的发生等方面均具有非常重要的作用。L1最初是从小鼠的小脑膜中发现，后来发现在有丝分裂后的神经元，髓鞘形成前及非形成髓鞘的雪旺细胞等组织中同样存在。

JuA with the concentrations 0.05g/L and 0.10g/L were tested based on the excitatory effect of 1000KIU/L penicillin and it was found that JuA could inhibit the burst induced by penicillin in CA1 pyramidal cells.

Studies also indicated that genistein exsists not only in soybeans but also in many kinds of plants such as vegetables and fruits.As a potential anticancer agent, the actional mechanisms of genistein mainly includes as follows:First, genistein can depress the activity of protein tyrosine kinase and transduction pathways for the phosphorylation of receptors and mitosis signal. So genistein can lead to cells' proliferation depressed. Second, genistein has minimal effects of phytoestrogens. It can be combined with estrogen receptor and improve the synthesis of cellular sex hormone binding glulobin, and improve the activity of UDP-glucuronyl transferase. Through these pathways, it can inhibit the cell activity of breast cancer and prostate cancer.
