摘要:


文题释义:

同位素相对标记与绝对定量技术(Tandem Mass Tag,TMT):由Thermo Scientific公司推出的一种同量异序化学标签,是通过串联质谱实现对多种不同样品中的蛋白进行同步鉴定和定量的有力工具,其具有高通量、高灵敏度、良好的重复性、低系统偏差和低噪声信号水平等优点,现已被认为是定量蛋白质组学研究领域中常用的高通量筛选技术。
发育性颈椎管狭窄:在1964年Hinck等首次提出的发育性颈椎管狭窄的基本概念,是指在颈椎的发育过程中,由于某些机体内外因素促使椎弓发育过短,椎管矢状径狭窄,这类患者容易遭受神经压迫和功能丧失,现已被确定为是诱发脊髓型颈椎病的重要危险因素。


背景:课题组前期研究发现气虚血瘀证是脊髓型颈椎病各种中医证型中的主要证型。然而,用于气虚血瘀证发育性颈椎管狭窄向脊髓型颈椎病转化的早期诊断蛋白组学标志物未见相关报道。

目的:探讨发育性颈椎管狭窄与脊髓型颈椎病的血清蛋白组学差异质,寻找并鉴定两者之间的潜在血清生物学标志物。
方法:分别采集气虚血瘀证脊髓型颈椎病患者 (实验组)血清9例、气虚血瘀证发育性颈椎管狭窄 (对照组) 血清9例,选用同位素相对标记与绝对定量技术 (TMT) 联合液相色谱-串联质谱(LC-MS/MS)技术进行蛋白组学分析,以此寻找并鉴定差异表达的蛋白质。

结果与结论:①TMT技术共筛选出有意义差异蛋白1 027种,最终鉴定出显著性差异蛋白89种 (P < 0.05),其中与对照组比较,实验组中α-肌动蛋白4、α-肌动蛋白1、细胞分裂控制蛋白42同系物、整合素连接蛋白激酶、Β-肌动蛋白等 45种蛋白表达上调;纤维连接蛋白、纤维蛋白原γ链、纤维蛋白原α链、纤维蛋白原β链等44种蛋白表达下调;②基于GO富集分析,这些差异蛋白参与了信号受体结合、激酶结合、蛋白激酶活性、整合素结合、肌动蛋白丝结合等分子功能;③KEGG 通路分析,筛选20条主要共同差异信号/代谢通路,分别为粘着斑、紧密连接、Rap1信号通路、血小板活化、肌动蛋白细胞骨架的调节等信号通路;④PPI分析表明,气虚血瘀证发育性颈椎管狭窄与脊髓型颈椎病之间的共同差异蛋白中ILK,FGA,FGB,FGG,FN1,CDC42,ACTN1,ACTN4,ACTB等位于蛋白质互作网络的节点,且与骨生成与破坏系统、神经系统、凝血系统、细胞炎症等系统关系密切;⑤结论:采用TMT联合LC-MS/MS技术成功筛选出了气虚血瘀证发育性颈椎管狭窄与脊髓型颈椎病之间的血清差异表达蛋白质,明确了ILK、FN1、CDC42、ACTN4是气虚血瘀证发育性颈椎管狭窄向脊髓型颈椎病转化的特异性标志物,为进一步阐明其转化机制提供了依据。

Abstract: BACKGROUND: Previous studies have found that qi deficiency and blood stasis syndrome is the main syndrome among various TCM syndromes of cervical spondylotic myelopathy. However, there is no report on proteomic markers as early diagnosis indicators for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome to cervical spondylotic myelopathy.
OBJECTIVE: To explore serum proteomics difference between developmental cervical spinal stenosis and cervical spondylotic myelopathy and to find and identify the potential serum biomarkers between them. 
METHODS: Serum samples of nine patients with cervical spondylotic myelopathy of qi deficiency and blood stasis syndrome (experimental group) and nine patients with developmental cervical spinal stenosis of qi deficiency and blood stasis syndrome (control group) were collected. The proteomic analysis was carried out by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry, so as to find and identify differentially expressed proteins.
RESULTS AND CONCLUSION: A total of 1027 significantly differential proteins were initially screened by TMT technology and 89 significantly differential proteins were finally identified (P < 0.05). Compared with the control group, there were 45 up-regulated proteins in the experimental group, such as α-actinin-4, α-actinin-1, cell division control protein 42 homolog, integrin-linked protein kinase and B-actin. Conversely, there were 44 down-regulated proteins in the experimental group compared with the control group, such as fibronectin, fibrinogen γ chain, fibrinogen α chain, fibrinogen β chain. Gene ontology enrichment analysis indicated that these differential proteins were involved in signal receptor binding, kinase binding, protein kinase activity, integrin binding, actin filament binding and other molecular functions. Based on the Kyoto Encyclopedia of Genes and Genomes pathway analysis, 20 common differential signal/metabolic pathways were identified, including Rap1 signaling pathway, adherens junction, tight junction, platelet activation, and regulation of actin cytoskeleton. Protein-protein interaction analysis showed that ILK, FGA, FGB, FGG, FN1, Cdc42, ACTN1, ACTN4 and ACTB were located at the nodes of protein-protein interaction network and were closely related to bone formation and destruction system, nervous system, coagulation system, cellular inflammation and other systems. To conclude, the serum differentially expressed proteins between developmental cervical spinal stenosis and cervical spondylotic myelopathy can be successfully screened by Tandem Mass Tag combined with liquid chromatography tandem mass spectrometry. ILK, FN1, CDC42 and ACTN 4 are identified as specific markers for the transformation of developmental cervical spinal stenosis with qi deficiency and blood stasis syndrome into cervical spondylotic myelopathy. These findings provide a basis for further clarifying the transformation mechanism.
