摘要/Abstract

摘要：

目的探讨穿心莲内酯（Andro）调控信号转导与转录激活因子3（STAT3）/谷胱甘肽过氧化物酶4（GPX4）通路对骨髓瘤细胞增殖和凋亡的影响。方法将人多发性骨髓瘤细胞（U266细胞）分为骨髓瘤组，Andro低、中、高浓度组，Stattic（STAT3抑制剂）组，Andro高浓度+Colivelin（STAT3激活剂）组。CCK-8法、克隆形成实验检测细胞增殖；流式细胞术检测细胞凋亡；透射电镜观察细胞线粒体形态；检测细胞线粒体膜电位、亚铁离子（Fe²⁺）、4-羟基壬烯醛（4-HNE）、丙二醛（MDA）、还原型谷胱甘肽（GSH）水平；2',7'-二氯二氢荧光素二乙酸酯（DCFH-DA）荧光探针检测细胞活性氧（ROS）水平；Western blot检测增殖细胞核抗原（PCNA）、B淋巴细胞瘤-2基因（Bcl-2）/Bcl-2相关X蛋白（Bax）、溶质载体家族7成员11（SLC7A11）、p-STAT3、GPX4蛋白表达。结果与骨髓瘤组比较，Andro低、中、高浓度组U266细胞线粒体均呈现明显形态学改变，OD₄₅₀值、克隆形成率、线粒体膜电位、GSH水平及PCNA、Bcl-2/Bax、SLC7A11、p-STAT3/STAT3、GPX4蛋白降低，细胞凋亡率、Fe²⁺、4-HNE、MDA水平、ROS水平升高（P<0.05）；与骨髓瘤组比较，Stattic组U266细胞对应指标变化趋势与上述一致（P<0.05）；Colivelin逆转了高浓度Andro对U266细胞铁死亡、凋亡的促进作用，以及对细胞增殖的抑制作用。结论 Andro可能通过抑制STAT3/GPX4通路诱导铁死亡，进而抑制多发性骨髓瘤细胞增殖并促进凋亡。

Abstract:

Objective To investigate the effect of andrographolide (Andro) on the proliferation and apoptosis of myeloma cells by regulating the signal transducer and activator of transcription 3 (STAT3)/glutathione peroxidase 4 (GPX4) pathway. Methods Human multiple myeloma U266 cells were divided into the myeloma group, the Andro low-concentration group, the Andro medium-concentration group, the Andro high-concentration group, the Stattic (STAT3 inhibitor) group and the Andro high-concentration + Colivelin (STAT3 activator) group. Cell proliferation was detected by CCK-8 assay and clone formation assay. Cell apoptosis was detected by flow cytometry. Mitochondrial morphology was observed by transmission electron microscopy. The levels of mitochondrial membrane potential, ferrous ion (Fe²⁺), 4-hydroxynonenal (4-HNE), malondialdehyde (MDA) and reduced glutathione (GSH) in cells were detected. The level of reactive oxygen species (ROS) in cells was detected by 2',7'-dichlorodihydrofluorescein diacetate (DCFH-DA) fluorescent probe. Western blot assay was used to detect the proteins including proliferating cell nuclear antigen (PCNA), B-cell lymphoma-2 (Bcl-2)/Bcl-2 associated X protein (Bax), solute carrier family 7 member 11 (SLC7A11), p-STAT3 and GPX4. Results Compared with the myeloma group, the mitochondria of U266 cells showed significant morphological changes in the Andro low-, medium- and high-concentration groups, the OD₄₅₀ value, clone formation rate, mitochondrial membrane potential, GSH level, and the protein levels of PCNA, Bcl-2/Bax, SLC7A11, p-STAT3/STAT3 and GPX4 were decreased, the cell apoptosis rate, the levels of Fe²⁺, 4-HNE, MDA and ROS were increased (P<0.05). Compared with the myeloma group, the changes in the corresponding indexes of U266 cells showed the same trend as above in the Stattic group (P<0.05). Colivelin reversed the promoting effect of high-concentration Andro on ferroptosis and apoptosis of U266 cells, as well as the inhibitory effect on cell proliferation. Conclusion Andro may induce ferroptosis by inhibiting the STAT3/GPX4 pathway, thereby inhibiting the proliferation and promoting the apoptosis of multiple myeloma cells.
