Abstract
Quantitative proteome analysis using iTRAQ is an important technique to find disease-related proteins. As an important component of tumor microenvironment, tissue interstitial fluid (TIF) has drawn a great attention for its potential as a source for exploration of the solid tumor biomarkers. On the basis of a mouse model of colorectal cancer (CRC) that was induced by the carcinogenetic reagents, we adopted a quantitative proteome analysis with iTRAQ to discover the CRC-related proteins in the TIFs and with MRM to evaluate the corresponding abundance changes in the individual mouse TIF and serum samples.
