Abstract目的:自噬在肿瘤的发生发展过程中发挥重要的调节作用。自噬调节剂将为抗肿瘤研究提供新的策略。本研究旨在从中药中筛选新的自噬调节剂。 方法:mRFP-GFP-LC3双荧光指示体系检测细胞内自噬流,筛选自噬调节剂;Western blot检测自噬相关蛋白和JNK/c-Jun通路的变化;siRNA下调JNK和c-Jun,Western blot检测LC3蛋白水平变化。 结果:mRFP-GFP-LC3双荧光指示体系分析表明23-乙酰泽泻醇B (23B)明显增强肿瘤细胞自噬流,并伴随着LC3-II 的升高;23B(15 μM)作用肿瘤细胞后,明显激活JNK/c-Jun信号通路;下调JNK和c-Jun或JNK抑制剂SP600125均可逆转23B引起的LC3-II的升高。 结论:23B能够调控肿瘤细胞自噬水平,其JNK/c-Jun信号通路激活可能是其促发自噬的分子机制。
