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。

It"s considered that the algae blooms control function in the algae"s growth dynamics model is influenced mostly by the water temperature, sun illumination, water flow speed and the concentration of the nutriment in water. A function including the four elements was built. By using cell mapping algorithm and contacting with the practical water condition of the Wujiang river and the Hanjiang river we analyzed and computed the algae blooms in the two areas and found the result was very near to the practical result. And we found that the ascend of water temperature and the descend of the water flow speed will contribute to the growth of algae and the nutriment is the substance basis of the algae blooms but not the only element. It must be under the condition of condign water temperature, enough sun illumination, slow water flow and abundant nutriment that algae blooms may break out unexpectedly.
本文认为藻类生长营养动力学模型中的水华爆发控制函数主要受水温、光照强度、水流速和营养盐浓度的影响,构建了包含水温、光照强度、水流速和营养盐浓度的水华爆发控制函数,通过对乌江、汉江的水华爆发进行胞映射分析,得到的计算结果与实际监测非常吻合,并认为水温升高和水流速下降将有利于藻类生长,营养盐是水华爆发的物质基础,但不是唯一因素,必须在适宜的水温、光照、缓慢的水流和充足的营养盐条件下,藻类才可能出现突发式的"疯长",即水华爆发。
