摘要:

文题释义:
代谢组学:诞生于20世纪末,由英国伦敦帝国大学Jeremy Nicholson教授创立,而后在基因组学时代兴起的一门跨领域学科,其主要目标是定量研究生命体对外界刺激、病理生理变化以及本身基因突变而产生的体内代谢物水平的多元动态反应。
液相色谱-质谱联用:色谱-质谱技术作为代谢组学研究最重要的工具,主要针对生物样本中小分子代谢物种类多、极性跨度大和浓度动态范围大的特点,以高效液相色谱作为分离系统,高分辨率质谱为检测系统的一种串联分析平台,与其他色谱-质谱联用技术相比,更适用于分析难挥发或热稳定性差的代谢物。

背景:研究报道,阿仑膦酸钠的摄入能显著提高骨质疏松症患者的骨密度。
目的:利用色谱-质谱技术分析比对阿仑膦酸钠干预去卵巢大鼠模型前后代谢物变化,进一步探索阿仑膦酸钠治疗骨质疏松症的具体机制及作用靶点。
方法:选择雌性SD大鼠36只,随机分为骨质疏松症组、阿仑膦酸钠组及假手术组,前两组采用去卵巢法建立骨质疏松症模型。造模4周后,阿仑膦酸钠组大鼠给予阿仑膦酸钠灌胃;假手术组和骨质疏松症组分别给予等体积生理盐水灌胃。连续灌胃12周后,通过色谱-质谱技术分析腰椎代谢物,得出共同差异代谢物,对其进行京都基因与基因组百科全书通路等生物信息学分析。
结果与结论:①3组共得到17种共同显著性差异代谢物;②通过京都基因与基因组百科全书富集分析表明,阿仑膦酸钠可能调节不饱和脂肪酸生物合成、亚油酸代谢等通路保护去卵巢模型大鼠;③结果提示,阿仑膦酸钠可能通过干预不饱和脂肪酸生物合成代谢和亚油酸代谢发挥其抗骨质疏松作用,从而达到预防骨质疏松症的目的。

Abstract: BACKGROUND: Studies have reported that alendronate intake significantly increases bone mineral density in patients with osteoporosis.
OBJECTIVE: To analyze and compare the changes in metabolites before and after alendronate intervention in ovariectomized rats by chromatography-mass spectrometry, and to further explore the specific mechanism and target of alendronate in the treatment of osteoporosis.
METHODS: A total of 36 female Sprague-Dawley rats were randomly divided into model group, alendronate sodium group and sham operation group. The osteoporosis model was established by ovariectomy in the first two groups. Four weeks after modeling, the rats in the alendronate group were intragastrically given alendronate sodium, while those in the sham operation group and model group were given equal volume of normal saline. After 12 weeks of continuous gavage, the metabolites of the lumbar spine were analyzed by chromatography-mass spectrometry, and the common differential metabolites were obtained, which were analyzed by bioinformatics such as Kyoto Gene and Genome Encyclopedia pathway.
RESULTS AND CONCLUSION: Totally 17 different metabolites were obtained in the three groups. The enrichment analysis of the Kyoto Encyclopedia of Genes and Genomes showed that alendronate sodium could regulate unsaturated fatty acid biosynthesis, linoleic acid metabolism and other pathways to protect ovariectomized rats. These results indicate that alendronate sodium may exert its anti-osteoporosis effect by interfering with unsaturated fatty acid bioanabolism and linoleic acid metabolism, so as to achieve the purpose of preventing osteoporosis.
