为了研究电压门控性钙通道β亚基和胶原纤维基因在扩展莫尼茨绦虫不同体节的mRNA转录水平,以beta-Tubulin基因作为内参基因,采用SYBR Green real-time RT-PCR方法检测该基因在扩展莫尼茨绦虫4个不同发育阶段即头节、幼节、成节、孕节中的表达差异。结果显示,电压门控性钙通道β亚基、胶原纤维基因和beta-Tubulin基因的Ct值与阳性质粒的浓度均呈良好的线性关系,相关系数均大于0.99;熔解曲线分析表明,产物为特异的单峰,具有较高的特异性。试验结果表明,电压门控性钙通道β亚基以及胶原纤维基因在虫体各发育阶段中的表达丰度存在差异。电压门控性钙通道β亚基在幼节的表达水平较高,而胶原纤维基因在孕节的表达水平较高,提示这2个基因可能在幼节和孕节的发育中有重要作用。
The CaV 2.3 encoded Ca2+ channel is one of the least well-known voltage-gated calcium channels in terms of physiology, pharmacology and clinical relevance. Epilepsy is a family of neurological disorders that are common and harmful to human health. More and more studies such as gene knock-out experiment have demonstrated that the channel is related to epileptic seizure, including participating to plateau potential generation, regulating intracellular Ca2+ concentration, CaV 2.3 splice variant, interacting with some muteins. In addition, some antiepileptic drugs inhibit the epileptiform discharges by targeting CaV 2.3 voltage-gated calcium channel.
