| Outline of Final Research Achievements |
Early detection of cancer metastasis is crucial to improve the prognosis. Cancer metastatic progression is influenced by surrounding tissue environment. Orthotopic implantation provides a valuable in vivo model for cancer metastasis research. Here, we established metastatic colorectal cancer cells by surgical orthotopic implantation of HCT-116 human colon cancer cells. These established cells demonstrated highly invasive potential. In this study, we performed differential proteomic profiling of metastatic cells for identification of colorectal cancer metastatic biomarker candidates. A total of 16541 distinct phosphopeptides were identified and hundreds of phosphopeptides were differentially expressed between metastatic and nonmetastatic cancer cells. And two metastasis-associated proteins were identified by functional analysis.
