心肌梗死(MI)后,左心室(LV)经历了一系列心脏创伤愈合反应,包括刺激强烈的炎症以清除坏死的心肌细胞和组织碎片,并诱导细胞外基质(ECM)蛋白合成以产生疤痕。蛋白质组学策略为我们提供了一种方法来索引在LV中表达的ECM蛋白,量化数量,确定功能,并探索相互作用。这篇综述将集中于蛋白质组学研究领域的努力,这些努力扩大了我们对心肌梗死后左室重构的理解,集中在不同蛋白质组方法的优势和局限性,以收集特定于心肌梗死后ECM周转的信息。我们将讨论样品制备和标记方案的最新进展如何增加我们在检测心脏ECM蛋白质组成分方面的成功。我们将总结蛋白质组学方法是如何随着时间的推移而发展到目前使用脱细胞部分或标记策略的无凝胶方法,这些方法将对临床应用有用。这篇综述将提供心脏ECM蛋白质组学在过去十年中如何演变的概述,并将提供对未来方向的洞察,这些方向将推动我们对心肌梗死后LV中心脏ECM周转的理解。
Following myocardial infarction (MI), the left ventricle (LV) undergoes a series of cardiac wound healing responses that involve stimulation of robust inflammation to clear necrotic myocytes and tissue debris and induction of extracellular matrix (ECM) protein synthesis to generate a scar. Proteomic strategies provide us with a means to index the ECM proteins expressed in the LV, quantify amounts, determine functions, and explore interactions. This review will focus on the efforts taken in the proteomics research field that have expanded our understanding of post-MI LV remodeling, concentrating on the strengths and limitations of different proteomic approaches to glean information that is specific to ECM turnover in the post-MI setting. We will discuss how recent advances in sample preparation and labeling protocols increase our successes at detecting components of the cardiac ECM proteome. We will summarize how proteomic approaches, focusing on the ECM compartment, have progressed over time to current gel-free methods using decellularized fractions or labeling strategies that will be useful for clinical applications. This review will provide an overview of how cardiac ECM proteomics has evolved over the last decade and will provide insight into future directions that will drive forward our understanding of cardiac ECM turnover in the post-MI LV.
