基于质谱法的胰液研究能够高通量鉴定胰腺分泌组中存在的蛋白质。胰液是由胰腺分泌到十二指肠中的消化蛋白、炎性蛋白和其他蛋白的复杂混合物,因此适合于基于质谱的蛋白质组学分析。内镜技术的最新进展,特别是内镜胰腺功能试验(ePFT),改善了蛋白质组学分析的胰液收集方法。在这里,我们提供了一个概述质谱为基础的蛋白质组学技术应用于研究的胰液。我们解决样品收集,蛋白质提取,质谱样品制备和分析,和生物信息学方法,并总结了目前的质谱为基础的调查胰液。然后,我们研究了这些技术在胰腺疾病研究中的局限性和未来潜力。我们的结论是,胰液代表了一个丰富的潜在的生物标志物和慢性胰腺炎的分子机制的研究可能会大大受益于质谱为基础的蛋白质组学。
Mass spectrometry-based investigation of pancreatic fluid enables the high-throughput identification of proteins present in the pancreatic secretome. Pancreatic fluid is a complex admixture of digestive, inflammatory, and other proteins secreted by the pancreas into the duodenum, and thus is amenable to mass spectrometry-based proteomic analysis. Recent advances in endoscopic techniques, in particular the endoscopic pancreatic function test (ePFT), have improved the collection methodology of pancreatic fluid for proteomic analysis. Here, we provide an overview of mass spectrometry-based proteomic techniques as applied to the study of pancreatic fluid. We address sample collection, protein extraction, mass spectrometry sample preparation and analysis, and bioinformatic approaches and summarize current mass spectrometry-based investigations of pancreatic fluid. We then examine the limitations and the future potential of such technologies in the investigation of pancreatic disease. We conclude that pancreatic fluid represents a rich reservoir of potential biomarkers and that the study of the molecular mechanisms of chronic pancreatitis may benefit substantially from mass spectrometry-based proteomics.
