摘要(Abstract):

该研究基于高效液相色谱-四极杆/静电场轨道阱高分辨质谱联用仪探究银杏黄酮苷元(ginkgo flavone aglycone, GA)联合阿霉素(doxorubicin, DOX)对H22肝癌细胞的抑制作用及作用机制。首先考察不同浓度GA和DOX对H22细胞存活率的影响,以组合指数(combination index, CI)对两者的联合用药进行评价。将实验分为对照组(CON)、DOX组、GA组、联合用药组(GDOX),通过代谢组学策略探寻联合用药较单独用药后显著改变的代谢标志物,分析可能的代谢通路和作用机制。结果显示,以30μg·mL(-1) GA与0.5μmol·L(-1) GA与0.5μmol·L(-1) DOX作为联合给药浓度,CI为0.808,表明两者联合发挥协同抗肿瘤作用。代谢组学分析鉴定出L-精氨酸、L-酪氨酸和L-缬氨酸等23种代谢标志物,以氨基酸类物质为主。与CON组相比,DOX治疗后22种代谢标志物被显著下调,GA治疗后17种代谢标志物被显著下调。相较于DOX和GA组,GDOX联合用药进一步下调了这些代谢标志物在肝癌中的水平,这可能是两者联合起到增效作用的原因。通路富集分析中找到5条关键代谢通路,包括谷胱甘肽代谢,苯丙氨酸代谢,精氨酸和脯氨酸代谢,β-丙氨酸代谢,缬氨酸、亮氨酸和异亮氨酸降解。这表明GA联合DOX的协同抗肿瘤作用,可能是通过干预多种氨基酸的代谢,进而影响肿瘤细胞的能量供应实现。
Ultra-high-performance liquid chromatography-Q exactive orbitrap tandem mass spectrometry(UHPLC-QEOrbitrap-MS/MS) was used to explore the inhibitory effect and mechanism of ginkgo flavone aglycone(GA) combined with doxorubicin(DOX) on H22 cells. The effects of different concentrations of GA and DOX on the viability of H22 cells were investigated, and combination index(CI) was used to evaluate the effects. In the experiments, control(CON) group, DOX group, GA group, and combined GA and DOX(GDOX) group were constructed. Then the metabolomics strategy was employed to explore the metabolic markers that were significantly changed after combination therapy on the basis of single medication treatment, and by analyzing their biological significance, the effect and mechanism of the anti-tumor effect of GA combined with DOX were explained. The results revealed that when 30 μg·mL(-1) DOX作为联合给药浓度,CI为0.808,表明两者联合发挥协同抗肿瘤作用。代谢组学分析鉴定出L-精氨酸、L-酪氨酸和L-缬氨酸等23种代谢标志物,以氨基酸类物质为主。与CON组相比,DOX治疗后22种代谢标志物被显著下调,GA治疗后17种代谢标志物被显著下调。相较于DOX和GA组,GDOX联合用药进一步下调了这些代谢标志物在肝癌中的水平,这可能是两者联合起到增效作用的原因。通路富集分析中找到5条关键代谢通路,包括谷胱甘肽代谢,苯丙氨酸代谢,精氨酸和脯氨酸代谢,β-丙氨酸代谢,缬氨酸、亮氨酸和异亮氨酸降解。这表明GA联合DOX的协同抗肿瘤作用,可能是通过干预多种氨基酸的代谢,进而影响肿瘤细胞的能量供应实现。

The results revealed that when 30 μg·mL(-1) GA and 0.5 μmol·L(-1) GA and 0.5 μmol·L(-1) DOX was determined as the co-administration concentration, the CI value was 0.808, indicating that the combination of GA and DOX had a synergistic anti-tumor effect. Metabolomics analysis identified 23 metabolic markers, including L-arginine, L-tyrosine and L-valine, mostly amino acids. Compared with the CON group, 22 and 17 metabolic markers were significantly down-regulated after DOX treatment and GA treatment, respectively. Compared with the DOX and GA groups, the treatment of GA combined with DOX further down-regulated the levels of these metabolic markers in liver cancer, which might contribute to the synergistic effect of the two. Five key metabolic pathways were found in pathway enrichment analysis, including glutathione metabolism, phenylalanine metabolism, arginine and proline metabolism, β-alanine metabolism, and valine, leucine and isoleucine degradation. These findings demonstrated that the combination of GA and DOX remarkably inhibited the viability of H22 cells and exerted a synergistic anti-tumor effect. The mechanism might be related to the influence of the energy supply of tumor cells by interfering with the metabolism of various amino acids.
