In RPE cell culture, Sox2 promoted the expression of retinal ganglion and amacrine markers, and suppressed the expression of genes associated with RPE properties.

在RPE细胞培养中，Sox2促进了视网膜神经节细胞和无长突细胞标记物的表达，并抑制RPE功能相关的基因的表达。

Results: The expression of both mRNA and protein of c-myc were obvious in the bud and cap stages,while decreased in the bell stage, then increased in ameloblast and dentinoblast when dentin formation. The expressions of c-myc were stronger in mesenchymal cells than in epithelial cells. The expression and distribution of c-myc mRNA is consistent with that of c-myc protein.

结果：c-myc mRNA及蛋白的表达在蕾状和帽状期明显，钟状期减弱，而牙体组织形成期成釉细胞、成牙本质细胞及间充质牙乳头细胞表达又增强。c-myc蛋白表达和分布与c-myc mRNA转录基本一致。

Results: Ameloblastin mRNA was negative under microscope in the ameloblast proliferate differentiation period, it showed weakly positive expression in intra-cellular and new-birth enamel matrix in secrete initial stage while it showed strongly positive expression in intra-cellular and new-birth enamel matrix when it came to secretion phase.

结果：釉鞘蛋白mRNA在成釉细胞增殖分化期表达为阴性，分泌初期细胞内及新生釉基质中开始出现弱阳性表达；至分泌期，细胞内及新生釉基质中均呈强阳性表达。

The general analytic expression of the space vector modulation wave was induced and the continuous and discontinuous modulation mode were unified by the analytic expression.

文中归纳出空间矢量调制调制波的通用解析表达式，并由此将连续调制和不连续调制统一起来。

CA II and AQP5 expression levels were determined by immunofluorescence and immunoblotting, while CA activity and Na, K-ATPase activity by a colorimetric assay. Anhidrotic mice treated by topiramate did not differ from controls in average secretory coil diameter, CA II expression, CA activity and Na, K-ATPase activity.

应用免疫荧光和western blot技术发现：小鼠在托吡酯处理后泌汗减少，碳酸酐酶同功酶II型(carbonic anhydraseII，CAII)蛋白表达未出现显著变化，但汗腺组织胞膜的水通道蛋白-5(aquaporin-5，AQP5)表达量下调。

In summary, our results indicate that hypohidrosis is a frequent adverse effect in children with topiramate therapy. Younger age and hot weather rather than drug dosage are independent risk factors for topiramate-associated hypohidrosis. The resultes also rule out the possibility that topiramate act on its known mechanisms of action, such as potentiating GABA activity at GABAA receptors and antagonizing the AMPA/KA subtype of glutamate receptor in the secretory cells of sweat glands to inhibit sweat secretion. Our data also suggest that topiramate impairs sudomotor function in mice and leads to a significant reduction in AQP5 expression in sweat glands of anhidrotic mice, thus raising the possibility that dysregulation of AQP5 may contribute to topiramate related hypohidrosis. CA inhibition may not be an important contributor since CA II expression and CA activity was intact in anhidrotic mice treated with topiramate.

综合全部实验结果，本研究提示：夏季和低龄是托吡酯引起泌汗障碍的主要危险因素，而托吡酯剂量对泌汗功能的影响较小；托吡酯可以抑制小鼠汗液的分泌，小鼠的年龄并不影响这种抑制作用，但托吡酯对小鼠体温无明显影响；托吡酯并不是通过对GABAA受体及AMPA和KA两种谷氨酸受体亚型的作用而在汗腺分泌细胞抑制泌汗；托吡酯不影响汗腺形态及Na，K-ATP酶活性；汗腺分泌细胞的AQP5功能失调可能与托吡酯引起的泌汗障碍密切相关，而碳酸酐酶抑制作用并不是泌汗功能损害的主要原因。

Who? I never heard of him, Paul said, before asking teammate James Posey if he had heard of him.
