摘要:

文题释义:
TMT技术:由Thermo Scientific公司推出的一种基于体外等重同位素标记的相对与绝对定量技术。该技术利用同位素试剂标记多肽末端氨基或赖氨酸侧链氨基基团,经高分辨质谱仪串联分析,可同时比较多达10种样品之间的蛋白质表达量,是近年来定量蛋白质组学常用的高通量筛选技术。
骨疏康胶囊:是在依据中医“补肾、益气、壮骨”等理论下构建,具有补肾益气、活血壮骨功效的中成药。近年来被广泛应用于临床防治绝经后骨质疏松症,可显著改善患者腰膝酸软、腰背疼痛、下肢痿弱等症状。
背景:骨疏康治疗骨质疏松症的具体机制及作用靶点尚未明确,需进一步深入研究。
目的:探究骨疏康保护骨质疏松模型大鼠骨代谢的机制,对差异表达蛋白进行生物信息学分析。
方法:36只雌性SD大鼠,去势法建立骨质疏松症模型大鼠24只,其中模型组12只,骨疏康组12只;假手术组12只为对照组。造模后,骨疏康组大鼠给予骨疏康灌胃[4.32 g/(kg·d)],1次/d;假手术组和模型组给予等体积生理盐水,1次/d。连续灌胃3个月后,测定大鼠胫骨骨密度;利用TMT-LC-MC/MC联用技术进行骨质疏松模型大鼠腰椎蛋白质组学分析,筛选出差异表达蛋白,对其进行GO、KEGG通路、蛋白互作分析,并构建蛋白质相互作用网络。实验方案经福建省中医药科学院动物实验伦理委员会批准。
结果与结论:①筛选出骨疏康组/模型组之间32个上调和49个下调的差异表达蛋白;②GO富集分析表明,他们参与免疫球蛋白受体结合、血管内皮生长因子受体结合等生物过程及核酸模板转录、RNA生物合成等分子功能;③KEGG富集分析表明,骨疏康组与模型组的差异表达蛋白主要参与酪氨酸代谢、乙醇代谢、JAK-STAT等信号通路;④PPI分析表明,骨疏康组和模型组的共同差异蛋白中Mecp2、Aldh3b1、Ryr1、Myoz1位于蛋白质互作网络的节点且与骨代谢关系密切;⑤结果显示,骨疏康可能通过调控差异蛋白及酪氨酸代谢、JAK-STAT等重要信号通路参与保护骨质疏松模型大鼠的骨代谢过程。

Abstract: BACKGROUND: The specific mechanism and target of Gushukang in the treatment of osteoporosis are still unclear, which need further explorations.
OBJECTIVE: To explore the protective mechanism of Gushukang on bone metabolism in osteoporotic rats and to analyze the differentially expressed proteins by bioinformatics.
METHODS: Twenty-four osteoporosis model rats were established by ovariectomy, 12 in model group and 12 in Gushukang group. Another 12 rats without ovariectomy were used as sham operation group. Gushukang capsule, 4.32 g/kg/d, was intragastrically administered once a day in the Gushukang group, and rats in the other two groups were given the same volume of normal saline. Treatment in each group lasted for 3 months. Bone mineral density of the tibia was measured. The proteomic analysis of the lumbar vertebrae of osteoporotic rats was carried out by TMT-LC-MC/MC technique, and the differentially expressed proteins were screened, analyzed by gene ontology, Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway and protein-protein interaction, thereby constructing a protein-protein interaction network. An ethical approval was obtained from the Animal Ethics Committee of Fujian Academy of Traditional Chinese Medicine.
RESULTS AND CONCLUSION: A total of 32 up-regulated and 49 down-regulated proteins were screened between Gushukang group and model group. Gene ontology enrichment analysis showed that these differentially expressed proteins were involved in biological processes, such as immunoglobulin receptor binding and vascular endothelial growth factor receptor binding, and molecular functions, such as nucleic acid template transcription and RNA biosynthesis. KEGG enrichment analysis showed that the differentially expressed proteins in the Gushukang group and model group were mainly involved in tyrosine metabolism, ethanol metabolism, JAK-STAT and other signal pathways. Protein-protein interaction analysis showed that among the common differential proteins in the Gushukang group and model group, Mecp2, Aldh3b1, Ryr1 and Myoz1 were located at the nodes of protein interaction network and were closely related to bone metabolism. These findings indicate that Gushukang granule may be involved in protecting the bone metabolism of osteoporotic rats by regulating differential proteins, tyrosine metabolism, JAK-STAT and other important signal pathways.
