冠状动脉微栓塞(CME)是一个重要的临床问题,与不良预后相关。 CME 的具体分子机制尚不完全清楚。在本研究中,我们建立了 CME 小鼠模型。相对和绝对定量 (iTRAQ) 的同量异位标签以及液相色谱与串联质谱 (LC-MS/MS) 技术鉴定出 CME 小鼠心肌组织中与假手术小鼠相比有 249 个差异表达的蛋白质。生物信息学分析表明,这些差异表达蛋白富集于多种能量代谢或细胞骨架组织相关过程或途径。定量PCR和蛋白质印迹验证实验表明,CME小鼠中琥珀酸脱氢酶(SDHA和SDHB)表达上调,Rho GDP解离抑制剂α(RhoGDIα)和Filamin-A(FLNA)表达显着下调。这些发现表明细胞骨架和能量代谢途径的改变在 CME 的发病机制中发挥着重要作用,未来的研究有必要验证靶向这些分子是否有助于减轻 CME 损伤。
Coronary microembolization (CME) is an important clinical problem, and it is related to poor outcome. The specific molecular mechanisms of CME are not fully understood. In the present study, we established a mice model of CME. Isobaric tags for relative and absolute quantitation (iTRAQ) and liquid chromatography coupled with tandem mass spectrometry (LC-MS/MS) technologies identified 249 differentially expressed proteins in the myocardial tissues of CME mice as compared with sham-operated mice. Bioinformatics analysis demonstrated that these differentially expressed proteins were enriched in several energy metabolism or cytoskeleton organization related processes or pathways. Quantitative PCR and Western blotting validation experiments revealed that succinate dehydrogenase (SDHA and SDHB) were upregulated, Rho GDP dissociation inhibitor α (RhoGDIα) and Filamin-A (FLNA) were downregulated significantly in CME mice. These findings indicated that the alternations of the cytoskeleton and energy metabolism pathways play important roles in the pathogenesis of CME, future studies are warranted to verify if targeting these molecules might be useful to alleviate CME injury or not.
