The sulfamate moiety in the structure of topiramate is chemically related to known CA inhibitors, and in fact, topiramate inhibits CA activity. To further explore the pharmacological action of topiramate, and clarify the possibility of anti-tumor growth and metastasis of CA inhibitors and its relation with AQP1, we studied the effect of topiramate on adhesion of high metastatic prostate carcinoma to laminin, and established the spontaneous metastatic model of Lewis lung carcinoma to studied the influences of topiramate on tumor growth and metastasis and AQP1 expression in lungs and primary tumors of mice.

为了深入研究托吡酯的药理作用，阐明CA抑制剂和水通道蛋白AQP1相互作用影响肿瘤生长和转移的可能性及其机制，我们研究了托吡酯对高转移的前列腺癌细胞粘附于基质成分层粘连蛋白的影响；以Lewis肺癌自发性转移为模型，考察了托吡酯对肿瘤生长和转移的影响；同时观察了托吡酯对荷瘤小鼠肺组织及原发瘤组织AQP1表达的影响；检测了其对血管新生的作用；利用体外AQP1表达模型，研究了CA抑制剂对AQP1功能的影响；此外，用蛋白质组学的关键技术，通过对模型组与托吡酯治疗组血清蛋白质组的比较分析，来寻找与肿瘤转移相关的蛋白质，探索托吡酯的可能作用靶点。
