基于核磁代谢组学技术的阿霉素肝毒性研究

Metabolomics study of doxorubicin induced hepatotoxicity

  • 摘要: 为探讨阿霉素致大鼠肝毒性的作用机制, 本研究采用1H NMR代谢组学技术对大鼠肝脏内源代谢物变化进行研究.通过多元统计分析, 鉴定了16个与阿霉素肝毒性密切相关的潜在生物标志物.进一步通过代谢通路分析 (MetPA), 发现阿霉素显著影响肝脏苯丙氨酸、酪氨酸和色氨酸生物合成, 缬氨酸、亮氨酸和异亮氨酸生物合成, 苯丙氨酸代谢, 甘氨酸、丝氨酸和苏氨酸代谢, 丙氨酸、天门冬氨酸和谷氨酸代谢, 以及酪氨酸代谢.阿霉素肝脏毒性的发生与干扰氨基酸、脂质、嘌呤代谢、能量代谢、生物转化及氧化应激等过程密切相关.本研究从代谢的角度分析了阿霉素对肝脏代谢的影响, 为进一步分析其毒性机制奠定了基础.

     

    Abstract: To reveal the underlying mechanism of doxorubicin induced hepatotoxicity, an NMR-based metabolomic approach combined with multivariate statistical analysis was used to observe its metabolic alternations of rat liver. Sixteen differential metabolites between model rats and normal rats were characterized as potential pathological biomarkers related to doxorubicin induced hepatotoxicity. Six pathways, including phenylalanine, tyrosine and tryptophan biosynthesis, valine, leucine and isoleucine biosynthesis, phenylalanine metabolism, glycine, serine and threonine metabolism, alanine, aspartate and glutamate metabolism, and tyrosine metabolism were regarded as the targeted metabolic pathways according to Metabolic Pathway Analysis (MetPA). The results suggested that the metabolic perturbations in rats with doxorubicin induced hepatotoxicity were mainly involved in amino acid metabolism, lipid pathways, purine metabolism, energy metabolism, dysfunction of biotransformation and oxidative stress. The investigation revealed the effects of doxorubicin on liver in a holistic metabolic way, which laid a foundation for further studies on its toxicity mechanism.
