摘要:


文题释义:

串联质谱标签蛋白质学技术:定量蛋白质组学是一种运用质谱进行化学标记来鉴定和定量蛋白质、核酸等生物大分子的技术,且相较于其他的凝胶与抗体定量等蛋白组学,串联质谱标签的高灵敏度、通量和可重复性等优势已成为了当前蛋白组学研究中的前沿方法。
发育性颈椎管狭窄:通常是由儿童颈椎后部附着结构的发育不良引起的,其侧位X射线片上表现出短椎弓根和扁平椎板,以及椎板与侧质量线后缘的重叠。


背景:正常健康人与发育性颈椎管狭窄(气虚血瘀证)人群之间的血清特异性生物学标志物尚未完全明确。

目的:寻找并鉴定气虚血瘀证发育性颈椎管狭窄的潜在生物学标志物。
方法:分别采集发育性颈椎管狭窄(气虚血瘀证)人群血清9例、健康正常人群血清8例,采用同位素相对标记与绝对定量技术串联质谱标签联合液相色谱-串联质谱筛选2组人群血清的差异蛋白及鉴定,使用Western Blot法对肌球蛋白轻链3(MYL3)差异蛋白进行验证。

结果与结论:①串联质谱标签技术:共鉴定出61个差异蛋白(P < 0.05),其中与健康正常人群组比,补体成分C1q受体、载脂蛋白A4、C-C基序趋化因子配体18等14种差异蛋白明显上调,而肌球蛋白轻链3、线粒体翻译延伸因子、核仁磷酸蛋白1等47种差异蛋白明显下调;②基因富集分析:这些差异蛋白可能参与染色体组织、线粒体膜组织、肌肉系统过程的调节等分子功能;③蛋白相互作用网络分析:健康正常人群与发育性颈椎管狭窄(气虚血瘀证)人群之间的共同差异蛋白中补体C1q受体、载脂蛋白A4、C-C基序趋化因子配体18、肌球蛋白轻链3、线粒体翻译延伸因子、核仁磷酸蛋白1等38种位于功能网络节点,且与颈椎骨能量代谢、骨细胞产生、破骨细胞的形成等系统关系密切;④运用Western Blot法对主要差异蛋白肌球蛋白轻链3进行验证:其验证结果与蛋白组学结果相一致;⑤结论:通过绝对定量技术联合液相色谱-串联质谱技术发现健康正常人群与发育性颈椎管狭窄(气虚血瘀证)人群之间的血清差异表达蛋白,并初步推测肌球蛋白轻链3可能是发育性颈椎管狭窄(气虚血瘀证)人群的特异性血清标志物。

Abstract: BACKGROUND: Serum-specific biomarkers between normal healthy individuals and populations with developmental cervical canal stenosis (Qi deficiency and blood stasis syndrome) have not been fully defined.
OBJECTIVE: To screen and identify the potential biomarkers of developmental cervical canal stenosis with Qi deficiency and blood stasis.
METHODS: Serum samples were collected from nine patients with developmental cervical canal stenosis with Qi deficiency and blood stasis and eight healthy people. Differentially expressed proteins in serum were screened and identified using isotope relative labeling and absolute quantification combined with liquid chromatography tandem mass spectrometry. Western blot was used to verify some significant differentially expressed proteins. 
RESULTS AND CONCLUSION: A total of 61 differentially expressed proteins (P < 0.05) were identified using tandem mass spectrometry techniques. Compared with the healthy normal population group, 14 differentially expressed proteins such as complement component C1q receptor, apolipoprotein A4, and C-C motif chemokine ligand 18 were significantly upregulated, while 47 differentially expressed proteins such as myosin light chain 3, mitochondrial translation elongation factor, and nucleolar phosphoprotein 1 were significantly downregulated. The results of gene ontology enrichment analysis indicated that these differentially expressed proteins might participate in molecular functions such as regulation of chromosomal tissue, mitochondrial membrane tissue, and muscle system processes. Protein-protein interaction network analysis showed that 38 common differential proteins, including complement component C1q receptor, apolipoprotein A4, C-C motif chemokine ligand 18, myosin light chain 3, mitochondrial translation elongation factor, and nucleolar phosphoprotein 1, were located at functional network nodes between healthy normal individuals and those with developmental cervical canal stenosis (Qi deficiency and blood stasis syndrome), and were closely related to the local energy metabolism of the cervical spine, the production of cervical vertebral osteocytes, and the formation of osteoclasts. The main differentially expressed protein myosin light chain 3 was validated using western blot assay, and the validation results were consistent with the proteomic results. To conclude, the preliminary discovery of differentially expressed proteins in serum between healthy normal individuals and those with developmental cervical canal stenosis (Qi deficiency and blood stasis syndrome) through absolute quantitative technology combined with liquid chromatography tandem mass spectrometry technology suggests that myosin light chain 3 may be a specific serum marker for developmental cervical canal stenosis (Qi deficiency and blood stasis syndrome).
