摘要/Abstract

摘要： 目的探讨L型钙通道(Cav1.2)下游信号通路中钙调蛋白/钙调蛋白依赖的蛋白激酶Ⅱ(CaM/ CaMKⅡ)与经前期综合征(PMS)肝气郁证的关系以及舒郁胶囊的干预机制。方法用舒郁胶囊、柴胡提取物、白芍提取物和阳性对照氟西汀+尼莫地平对慢性束缚应激法制备的PMS肝气郁证大鼠进行干预,免疫印迹技术检测各组海马中CaM,CaMKⅡ的磷酸化水平及脑源性营养因子(BDNF)蛋白表达。结果慢性束缚应激可以成功复制PMS肝气郁证大鼠模型。蛋白表达结果显示,模型组大鼠海马中CaM蛋白的表达量升高(P<0.05),CaMKⅡ磷酸化水平显著升高, BDNF蛋白的表达量显著下降(P<0.01)。与模型组相比,氟西汀+尼莫地平组大鼠海马CaM蛋白表达量显著降低(P<0.05),各给药组海马中CaMKⅡ磷酸化水平显著下降(P<0.01),BDNF的蛋白表达量均显著升高(P<0.01, P<0.05)。结论海马脑区Cav1.2下游信号通路中CaM/ CaMKⅡ的激活与PMS肝气郁证的发生有关,舒郁胶囊及其有效组分可能是通过抑制CaMKⅡ信号通路的激活发挥其治疗作用。

Abstract: Objective To study the relationship of L-type calcium channel (Cav1.2) mediated calmodulin/calmodulin-dependent protein kinase II (CaM/CaMKII) signaling pathway with premenstrual syndrome (PMS) with liver-qi stagnation, and elucidate the Shuyu capsule intervention mechanism. Methods The PMS model rats with liver-qi stagnation were induced by bondage stimulation, and the model rat were treated with Shuyu capsule, the extract from Radix Bupleuri and Radix Paeoniae, and fluoxetine+nimodipine as positive control. The experiment were divided into six groups: normal group, model group, Shuyu group, Radix Bupleuri, Radix Paeoniae group and fluoxetine+nimodipine group. The expression level of CaM, brain-derived neurotrophic factor (BDNF) and phosphorylation level of CaMKII were detected by Western blotting. Results Compared with the normal group, the protein expression level of p-CaMK II increased and BDNF decreased significantly in hippocampus of model rats. After treating with our medication the protein expression of CaM and CaMK II phosphorylation level decreased obviously, the expression level of BDNF increased markedly (P<0.05; P<0.01). Conclusion We hypothesized that the CaM/CaMKⅡcalcium signal pathway mediated by Cav1.2 may play important role in the pathogenesis of PMS Liver-qi stagnation and maybe the molecular targets of Shuyu capsule to treatment PMS with Liver-qi stagnation.
