Proteomic Profiling of Human Extracellular Vesicles Reveals Diagnostic Biomarkers for Colon Adenocarcinoma

Puntos clave

• The study aims to identify specific proteins in extracellular vesicles that can act as biomarkers for early detection of colon adenocarcinoma.
• Profiled extracellular vesicle proteome from 233 human patients with colon adenocarcinoma.
• Analyzed matched pairs of tumor and non-tumor colon tissues and pre/post-operative plasma samples.
• Utilized liquid chromatography-tandem mass spectrometry (LC-MS/MS) for proteomic analysis.
• Identified 745 proteins enriched in tumor-derived extracellular vesicles.
• Developed a 10-protein panel that distinguishes colon adenocarcinoma patients from healthy controls with over 90% sensitivity.
• Observed significant decrease in tumor-associated proteins post-surgery, while healthy-associated proteins normalized.
