摘要
目的 应用代谢组学技术研究服用伊马替尼与尼洛替尼的慢性粒细胞白血病(CML)患者血浆代谢差异,探讨其对CML患者血浆内源性代谢物干预作用的差异性.方法 选取2015年3月至2015年6月在苏州大学附属第一医院就诊的获得最佳疗效的CML慢性期患者34例,按服用药物分为伊马替尼组(19例)和尼洛替尼组(15例).采用回顾性病例对照研究方法,应用气相色谱-质谱(GC-MS)技术,对两组患者血浆样本中内源性小分子代谢物进行全面检测,采集代谢物指纹图谱,利用多变量数据分析及t检验筛选差异代谢物,并通过MetPA分析平台探讨差异代谢物相关的代谢通路.结果 应用GC-MS代谢组学方法可以区分伊马替尼与尼洛替尼.结合变量权重重要性(VIP)值及t检验筛选到差异代谢物,伊马替尼组中苯丙氨酸、吲哚丙酸、肉豆蔻酸、半乳糖、葡萄糖、软脂酸、色氨酸、硬脂酸、邻苯二甲酸及邻苯二甲酸酯含量较低,其VIP值分别为1.633(t=6.099,P<0.001)、1.338(t=4.367,P<0.001)、1.557(t=6.716,P<0.001)、1.154(t=3.056,P=0.005)、1.941(t=2.196,P=0.035)、1.207(t=3.785,P=0.001)、1.625(t=6.398,P<0.001)、1.555(t=6.553,P<0.001)、1.633(t=7.679,P<0.001)、1.633(t=8.374,P<0.001).主要涉及色氨酸代谢、苯丙氨酸代谢及半乳糖代谢通路.结论 应用代谢组学方法找到了CML患者伊马替尼与尼洛替尼的血浆内源性差异代谢物,这些差异可能与药物成分配比及药物体内代谢差异有关.
Objective To compare the effects of imatinib and nilotinib on plasma endogenous metabolites in patients with chronic myelogenous leukemia (CML) by using metabolomics method. Methods The clinical data of 34 CML patients treated with imatinib and nilotinib who were diagnosed and successfully treated in the First Affiliated Hospital of Soochow University from March 2015 to June 2015 were enrolled. According to the therapeutic drugs, cases were divided into imatinib group (19 cases) and nilotinib group (15 cases). Gas chromatography-mass spectrometer (GC-MS) was used to identify metabolic fingerprint and t test was used to look for different metabolites. Finally, MetPA analysis platform was employed to explore the related metabolic pathways in CML patients. Results GC-MS metabolomics method showed a significant distinction metabolites expression mode between imatinib group and nilotinib group. The ultimate different metabolites contained phenylalanine, indolepropionate, tetradecanoic acid, galactose, glucose, hexadecanoic acid, tryptophan, octadecanoic acid, phthalic acid and phthalate, and their variable importance in projections (VIPs) were 1.633 (t= 6.099, P〈 0.001), 1.338 (t= 4.367, P〈 0.001), 1.557 (t= 6.716, P〈 0.001), 1.154 (t= 3.056, P= 0.005), 1.941 (t= 2.196, P= 0.035), 1.207 (t= 3.785, P= 0.001), 1.625 (t= 6.398, P〈0.001), 1.555 (t=6.553, P〈0.001), 1.633 (t=7.679, P〈0.001) and 1.633 (t=8.374, P〈0.001), respectively, which were related to tryptophan metabolism, phenylalanine metabolism and galactose metabolism pathways. Conclusion GC-MS based on metabonomic technology can successfully find different metabolites in CML patients treated with imatinib and nilotinib, which may be associated with drug components and pharmacodynamic differences.
