摘要:

目的:探讨预知子诱导人非小细胞肺癌(NSCLC)细胞死亡方式及机制。方法:通过CCK-8实验、Hochest33342/PI染色实验以及克隆形成实验检测预知子对细胞生存、增殖能力的影响,采用Western blot检测预知子干预后对NSCLC细胞内死亡相关蛋白ATG5、HMGB1、GPX4,凋亡蛋白及PI3K-Akt信号通路相关蛋白的表达变化,采用流式细胞术检测细胞凋亡率,通过DCFH-DA荧光探针法观察检测细胞内活性氧(ROS)水平。结果:预知子能明显抑制NSCLC细胞的存活率和增殖能力(P<0.05),预知子处理后NSCLC细胞内凋亡相关蛋白BAX、Cleaved caspase3和Cleaved caspase9表达显著上调(P<0.05),p-PI3K、p-Akt和BCL2蛋白表达均明显下调(P<0.05),预知子可明显促进NSCLC细胞的凋亡率和细胞内ROS量升高(P<0.05),抗氧化剂NAC能逆转预知子导致的NSCLC细胞凋亡、ROS水平升高及PI3K-AKT通路蛋白的调控作用(P<0.05)。结论:预知子通过ROS 介导的PI3K-Akt通路导致了NSCLC细胞凋亡。

Abstract:

AIM: To explore the way and mechanism of cell death induced by Fructus Akebiae in non-small cell lung cancer (NSCLC) cells. METHODS: CCK-8, Hochest33342/PI staining, and colony formation experiments were used to detect cell viability and proliferation. Western blot was used to detect the expression of cell death-related proteins ATG5, HMGB1, GPX4, apoptosis-related proteins, and PI3K-Akt signaling pathway-related proteins. Flow cytometry was used to detect the apoptosis rate. DCFH-DA fluorescent probes were used to detect the levels of total intracellular ROS under a fluorescence microscope. RESULTS: Fructus Akebiae significantly inhibited the cell viability and proliferation of human NSCLC cells (P<0.05). The expression of apoptosis-related proteins BAX, Cleaved caspase3, and Cleaved caspase9 in NSCLC cells was significantly increased (P<0.05), while p-PI3K, p-Akt, and BCL2 were markedly decreased (P<0.05). Fructus Akebiae was found to clearly increase the apoptosis rate and the levels of total intracellular ROS (P<0.05). The antioxidant NAC significantly reversed apoptosis, ROS production and regulation of PI3K-Akt pathway related proteins induced by Fructus Akebiae (P<0.05). CONCLUSION: Fructus Akebiae induces apoptosis via regulating ROS-mediated PI3K-Akt signaling pathway in non-small cell lung cancer cells.
