摘要:

目的 通过体外实验双乙酰丙酮氧钒[VO(acac)2]对人肾上腺皮质癌SW-13、NCl-H295R细胞系的作用,了解VO(acac)2是否对肾上腺皮质癌细胞的增殖、迁移和侵袭具有促进或抑制作用。 方法 取对数生长期的 SW-13和 NCI-H295R 细胞,用6.25、12.5、25、50、75、100、200 μmol/L的VO(acac)2分别干预SW-13、NCI-H295R细胞24和48 h,米托坦作为阳性对照组。CCK-8(cell counting kit-8)检测VO(acac)2对SW-13、NCI-H295R细胞活力的影响;后用0、6.25、12.5、25 μmol/L的VO(acac)2分别干预SW-13、NCI-H295R细胞48 h,流式细胞术检测VO(acac)2对SW-13、NCI-H295R细胞凋亡的影响;划痕实验检测VO(acac)2对SW-13、NCI-H295R细胞迁移能力的影响;Transwell 实验检测VO(acac)2对SW-13、NCI-H295R细胞侵袭能力的影响;克隆实验检测VO(acac)2对SW-13、NCI-H295R细胞增殖能力的影响。 结果 CCK-8 结果显示VO(acac)2呈时间和浓度依赖性抑制SW-13、NCI-H295R细胞的活力,VO(acac)2对SW-13细胞作用24及48 h的半数抑制浓度(half-maximal inhibitory concentration, IC50)分别为(62.98 ± 6.67)、(14.61 ± 1.66) μmol/L,对NCI-H295R作用24及48 h的IC50分别为(46.78 ± 7.89)、(12.61 ± 2.98) μmol/L。流式细胞术结果显示VO(acac)2呈浓度依赖性促进SW-13、NCI-H295R 细胞的凋亡(P < 0.05)。划痕实验结果示随着VO(acac)2干预浓度增加,SW-13、NCI-H295R细胞的迁移率随之下降(P < 0.05)。Transwell实验结果示VO(acac)2可呈浓度依赖性抑制SW-13、NCI-H295R细胞的侵袭能力。克隆实验结果显示VO(acac)2可呈浓度依赖性抑制SW-13、NCI-H295R 细胞的增殖能力。 结论 VO(acac)2可抑制人肾上腺皮质癌细胞SW-13、NCI-H295R的增殖、迁移和侵袭能力,诱导其凋亡。

Abstract:

Objective To investigate the effects of bis(acetylacetonato)oxovanadium(IV) [VO(acac)?] on human adrenocortical carcinoma cell lines SW?13 and NCI?H295R in vitro, aiming to determine whether VO(acac)? promotes or inhibits the proliferation, migration, and invasion of these cells. Methods SW?13 and NCI?H295R cells in logarithmic growth phase were exposed to VO(acac)? at concentrations of 6.25, 12.5, 25, 50, 75, 100, and 200 μmol/L for 24 and 48 hours, respectively. Mitotane served as the positive control. Cell viability was assessed using the CCK?8 assay to evaluate the effects of VO(acac)? on SW?13 and NCI?H295R cells. Subsequently, cells were treated with VO(acac)? at concentrations of 0, 6.25, 12.5, and 25 μmol/L for 48 hours, and flow cytometry was employed to investigate the impact of VO(acac)? on apoptosis. The migratory ability of the cells was evaluated using a wound healing assay, while their invasive capacity was assessed via a Transwell assay. Additionally, the clonogenic assay was used to determine the proliferative potential of SW?13 and NCI?H295R cells following VO(acac)? treatment. Results The CCK?8 results demonstrated that VO(acac)2 inhibited the viability of SW?13 and NCI?H295R cells in a time? and concentration?dependent manner. Specifically, the half?maximal inhibitory concentrations (IC50) for VO(acac)2 against SW?13 cells were 62.98 ± 6.67 μmol/L after 24 hours and (14.61 ± 1.66) μmol/L after 48 hours of treatment, while the corresponding IC50 values for NCI?H295R cells were 46.78 ± 7.89 μmol/L and 12.61 ± 2.98 μmol/L, respectively. Flow cytometry analysis revealed that VO(acac)2 induced apoptosis in both SW?13 and NCI?H295R cells in a concentration?dependent manner (P < 0.05). The wound healing assay indicated a significant reduction in the migratory rate of SW?13 and NCI?H295R cells with increasing concentrations of VO(acac)2P < 0.05). Transwell assay results showed that VO(acac)2 significantly inhibited the invasive ability of SW?13 and NCI?H295R cells in a concentration?dependent fashion. Finally, the clonogenic assay confirmed that VO(acac)2 suppressed the proliferative capacity of SW?13 and NCI?H295R cells in a concentration?dependent manner. Conclusion VO(acac)2 inhibits the proliferation, migration, and invasion of human adrenocortical carcinoma cells (SW?13 and NCI?H295R), while inducing apoptosis in these cell lines.
