| Outline of Final Research Achievements |
In this study, we aimed to explore the metastatic marker from colorectal cancer tissue and to develop an early diagnosis method of metastasis using blood exosome. Quantitative proteomic analysis of mambrane proteins in 24 tissues of primary and metastatic lesion in the same patient with colorectal cancer identified 182 potential metastatic biomarker candidate proteins with different expression levels between primary and metastatic lesion . Next, we examined whether these proteins can be detected and quantified in blood exosomes using the SRM / MRM method. As a result, it was suggested that two proteins could diagnose metastatic colorectal cancer with high accuracy. These proteins were considered promising as a metastatic marker of colorectal cancer.
