摘要:


文题释义:

串联质量标签蛋白质组学:又名TMT蛋白组学,TMT (Tandem mass tag)是由Thermo Fisher Scientific公司研发的一种多肽体外等重同位素标记的相对与绝对定量技术,采用6,10及16种同位素的标签,通过特异性标记多肽的氨基基团,经高分辨质谱仪串联分析,可同时比较多达16种样品之间的蛋白质表达量,是定量蛋白质组学中的高通量筛选技术。
阿仑膦酸钠:是治疗骨质疏松症应用历史最长的药物之一,可通过多种作用机制治疗骨质疏松症。抑制破骨过程、维持骨结构、改善矿化程度、增加皮质厚度和骨密度从而提高骨强度,减轻和预防骨质疏松,有效降低椎体、髋骨和其他部位的骨折危险。


背景:目前关于阿仑膦酸钠治疗骨质疏松症的作用机制及作用靶点,仍需深入研究。

目的:探究阿仑膦酸钠调节骨质疏松模型大鼠骨代谢的作用机制,并进行差异表达蛋白生物信息学分析。
方法:雌性SD大鼠随机分为模型组、阿仑膦酸钠组、假手术组,每组12只,前两组均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予阿仑膦酸钠灌胃;另外两组予等体积生理盐水。连续灌胃12周后测定胫骨骨密度,采用串联质量标签联合液相色谱-串联质谱法联用技术对大鼠腰椎进行蛋白质组学分析,筛选出差异表达蛋白,并进行基因本体、京都基因和基因组百科全书通路及蛋白相互作用网络分析。

结果与结论:①筛选出阿仑膦酸钠组与模型组组间上调/下调差异表达蛋白分别为32个/51个;②基因本体富集分析结果显示,差异表达蛋白主要参与结合、催化活性等分子功能以及细胞过程、代谢过程等生物过程;③京都基因和基因组百科全书富集分析结果显示,阿仑膦酸钠组/模型组组间差异表达蛋白功能主要参与泛酸和辅酶A的生物合成过程;④蛋白相互作用分析结果表明,阿仑膦酸钠组/模型组组间共同差异表达蛋白中Hspa1l、Enpp3、Unc45a、Myh9、Cant1位于蛋白互作网络节点并与骨代谢密切相关;⑤结果显示,阿仑膦酸钠可能通过调控差异表达蛋白及泛酸和辅酶A生物合成过程来调节骨质疏松模型大鼠的骨代谢。

Abstract: BACKGROUND: The mechanisms and targets of alendronate in the treatment of osteoporosis still need to be investigated in depth. 
OBJECTIVE: To investigate the mechanism by which alendronate regulates bone metabolism in rats with osteoporosis and to perform a bioinformatics analysis of differentially expressed proteins. 
METHODS: Female Sprague-Dawley rats were randomly divided into three groups (n=12 per group): model group, alendronate group and sham-operated group. Animal models of osteoporosis were prepared using ovariectomy in the model and alendronate groups. At 4 weeks after modeling, rats in the alendronate group were gavaged with alendronate; the other two groups were given the equal volume of normal saline. After 12 weeks of continuous gavage, the bone mineral density of the tibia was measured and the lumbar spine of the rats was taken for proteomic analysis using Tandem mass tag-liquid chromatography-tandem mass spectrometry technique to identify differentially expressed proteins for gene ontology, Kyoto Encyclopedia of Genes and Genomes pathway and protein-protein interaction analysis.
RESULTS AND CONCLUSION: There were 32 up-regulated proteins and 51 down-regulated proteins identified between the alendronate group and model group. Gene ontology enrichment analysis showed that the differentially expressed proteins were mainly involved in molecular functions, such as binding and catalytic activity, and in biological processes, such as cellular process and metabolic process. Kyoto Encylopedia of Genes and Genomes enrichment analysis showed that the differentially expressed proteins in the alendronate group and model group were mainly involved in the biosynthesis of pantothenate and coenzyme A. Protein-protein interaction analysis indicated that among the differentially expressed proteins in the alendronate group and model group, Hspa1l, Enpp3, Unc45a, Myh9 and Cant1 were located at the nodes of the protein-protein interaction network and were closely related to bone metabolism. Overall, these findings indicate that alendronate may regulate bone metabolism in the rat model of osteoporosis by regulating the expression of differentially expressed proteins and biosynthesis of pantothenate and coenzyme A.
