摘要: 目的 探讨淫羊藿素抑制人源性前列腺癌LNCaP细胞珠BALB/c-nu 裸小鼠荷瘤组织磷脂酰肌醇3-激酶/蛋白激酶B(P13K/Akt) 信号通路及其相关蛋白磷酸化的可能机制。方法 将40只雄性BALB/c-nu裸小鼠按随机对照原则均分为4组[对照组、前列腺癌(PCa)组、阳性药组和实验组]并采用前列腺内注射LNCaP细胞株构建PCa动物模型。实验组每日按0.1 mL/10 g尾静脉注射0.8%淫羊藿素,阳性药组按0.1 mL/10 g尾静脉注射P13K/ Akt抑制剂LY294002,对照组和PCa组注射等体积生理盐水。注射4周后比较裸小鼠体质量、前列腺瘤体湿重、体积及P13K/Akt 信号通路相关蛋白表达。结果 与PCa组比较,实验组前列腺瘤体湿重、体积、P13K、 p-Akt、磷酸化雄激素受体(p-AR)、雄激素受体剪接变异体7(AR-V7)和降钙素(Calcitonin)均较模型组降低(P<0.05),而钙黏蛋白E(E-cadherin) 升高(P<0.05)。结论 淫羊藿素通过调节PI3K/Akt信号通路抑制PCa的进展,且这一作用与Akt及AR磷酸化有关。

Abstract: Objective To explore the possible mechanism of icariin inhibiting phosphoinositide 3-kinase/protein kinase B (P13K/Akt) signaling pathway and phosphorylation of related proteins in human prostate cancer (LNCaP) BALB/c-nu nude mice. Methods Totally 40 male BALB/c-nu nude mice were randomly divided into 4 groups (control group, prostate cancer group, positive drug group and experimental group) and the human prostate cancer model was established by intraprostate injection of LNCaP. The experimental group was injected 0.8% icariin by 0.1 mL/(10 g·d) tail vein, the positive group was injected 0.1 mL/10 g tail vein P13K/Akt inhibitor LY294002, and control group and the prostate cancer group were injected the same volume of normal saline. The body weight, wet weight, volume and P13K/Akt signaling pathway-related protein expression in nude mice were compared after 4 weeks of injection. Results The wet weight, volume, P13K, P-Akt, P-AR, AR-V7 and Calcitonin of prostate cancer tissues in the experimental group were lower than those in the model group (P<0.05), while E-cadherin was higher (P<0.05). Conclusion Icariin inhibits the progress of LNCaP by regulating PI3K/ Akt signaling pathway, which is related to the phosphorylation of Akt and AR.
