摘要: 目的 观察新抗癌天然产物裂果薯总皂苷(SSPH)对HepG2和Huh7肝癌细胞铁死亡相关基因谷胱甘肽过氧化物酶4(GPX4)、溶质载体家族7成员11(SLC7A11)和酰基辅酶A合成酶长链家族成员4(ACSL4)表达的影响。方法 分别取HepG2和Huh7细胞,分为对照组(DMEM)和小(0.73 μM)、中(1.46 μM)、大剂量(2.91 μM)SSPH处理组。采用MTT法检测细胞增殖活性,采用苯啰啉比色法检测Fe2+浓度,采用荧光探针法检测活性氧(ROS)水平,采用qRT-PCR法检测GPX4、SLC7A11和ACSL4 mRNA水平,采用Western blot法检测对应蛋白表达。结果 小、中和大剂量SSPH处理组HepG2和Huh7肝癌细胞增殖活性降低,且抑制作用呈剂量-时间依赖性(P<0.05);处理组HepG2细胞和Huh7细胞ROS水平均显著高于对照组(P<0.05),细胞Fe2+含量也均显著高于对照组(P<0.05);处理组HepG2细胞和Huh7细胞GPX4和SLC7A11 mRNA相对水平均显著低于对照组(P<0.05),而ACSL4 mRNA水平则显著高于对照组(P<0.05);处理组HepG2和Huh7细胞GPX4和SLC7A11表达比对照组显著下调(P<0.05),而ACSL4表达比对照组显著上调(P<0.05)。结论 新抗癌天然产物SSPH可通过诱导肝癌细胞铁死亡发挥抗肝癌作用,其机制可能与调控ACSL4、GPX4和SLC7A11等铁死亡相关基因表达,促进细胞内ROS积累和Fe2+过载有关。

Abstract: Objective The aim of this experiment was to investigate effects of schizocapsa plantaginea hance (SSPH), a new anti-cancer natural product, on expressions of ferroptosis-related genes, e.g., glutathione peroxidase 4 (GPX4), solute carrier family 7 member 11 (SLC7A11) and acyl-CoA synthase long-chain family member 4 (ACSL4) in HepG2 and Huh7 cells in vitro. Methods HepG2 and Huh7 cells were respectively divided into control (DMEM), low-dose (0.73 μM), medium-dose (1.46 μM) and high-dose (2.91 μM) SSPH-intervened groups. Cell proliferations were detected by MTT, supernatant Fe2+ concentration was determined by o-phenanthroline colorimetry, and reactive oxygen species (ROS) was assayed by fluorescence probe. GPX4, SLC7A11 and ACSL4 mRNA were detected by qRT-PCR and the corresponding protein expressions were detected by Western blot. Results HepG2 and Huh7 cell proliferation greatly in a dose-dependent manner inhibited in low-, medium- and high-dose SSPH-intervened groups as compared to in the control(P<0.05); supernatant ROS and Fe2+contents in SSPH-intervened HepG2 and Huh7 cells were significantly increased compared to in the control group (P<0.05);cell GPX4 and SLC7A11 mRNA relative levels in SSPH-intervened HepG2 and Huh7 cells decreased (P<0.05), while ACSL4 mRNA relative level increased greatly compared to in the control (P<0.05); cell GPX4 and SLC7A11 protein expression SSPH-intervened HepG2 and Huh7 cells weaken significantly(P<0.05), while ACSL4 protein expression intensified significantly compared to in the control group (P<0.05). Conclusion SSPH could exert anti-liver cancer effect by inducing ferroptosis in hepatoma cells, and the mechanism by which the intracellular ROS and Fe2+ were overloaded, might be related to regulation of ferroptosis-related genes, e.g., ACSL4, GPX4 and SLC7A11 expressions.
