摘要: 目的 从组学水平可视化5-羟甲基糠醛(5-HMF)给药后肾脏组织代谢的时空变化,探索可能的肾毒性机制。方法 5-HMF 300 mg·kg-1静脉给药ICR小鼠(给药组),对照组给予生理盐水,于1、4、24 h时间点分别取材肾组织,制作冰冻组织切片;采用空气动力辅助解吸电喷雾离子化质谱成像(AFADESI-MSI)技术,获取各类代谢物在组织切片中的空间分布;按肾脏的解剖区域提取代谢物信息,结合时空的多变量统计分析,筛选并鉴定毒性相关差异代谢物进行通路富集分析。结果 两组间主要差异代谢物有苯丙氨酸、腺苷、腺嘌呤、次黄嘌呤、鸟苷单磷酸、FA-22∶6等,重要的代谢通路为嘌呤代谢、丙氨酸天冬氨酸和谷氨酸代谢、精氨酸合成、三羧酸循环和嘧啶代谢5个通路。同时发现长链脂肪酸和磷脂类上调,提示5-HMF毒性机制还可能与扰乱脂肪酸氧化和脂质代谢相关。将不同时间点的差异代谢物进行对比,挖掘出次黄嘌呤、FA-22∶6、LPG-22∶6可作为潜在的毒性预测标志物,给药后4 h为最佳检测时间。结论 该方法实现了5-HMF引起肾脏代谢的时空分析,揭示了5-HMF可能的肾毒性机制,展现了质谱成像技术应用于药物毒理学方面的优势。

Abstract: Objective To explore the spatial and temporal metabolic profiles of kidney after 5-hydroxymethylfurfural (5-HMF) administration and elucidate possible mechanisms of the nephrotoxicity from the omics level. Methods ICR mice were divided into control group and administration group, which were intravenously injected with saline and 5-HMF (300 mg·kg-1), respectively. Kidney tissues were collected at 1, 4 and 24 hours time points, and then the frozen renal tissue sections were scanned and visualized by air flow-assisted desorption electrospray ionization mass spectrometry imaging (AFADESI-MSI). Microregional metabolic information was extracted, and then the differential metabolites at each time point were screened out for identification and pathway enrichment analysis. Results The main difference metabolites between the administration group and the control group were phenylalanine, adenosine, adenine, hypoxanthine, guanosine monophosphate, FA-22∶6 and others. The important metabolic pathways are purine metabolism, alanine aspartate and glutamate metabolism, arginine biosynthesis, TCA cycle and pyrimidine metabolism. Meanwhile, long chain fatty acids and phospholipids were up-regulated, suggesting that the toxicity mechanism of 5-HMF may also be related to the disruption of fatty acid oxidation and lipid metabolism. By comparing the different metabolites at each time point, hypoxanthine, FA-22∶ 6 and LPG-22∶ 6 could be used as potential toxicity prediction biomarkers, and the best detection time was 4 h after administration. Conclusion This method can realize the spatiotemporal analysis of kidney metabolism caused by 5-HMF, reveal the possible nephrotoxicity mechanism of 5-HMF, and demonstrate the advantages of mass spectrometry imaging technology in drug toxicology studies.
