Research Abstract

Since metastasis is one of the most important prognostic factors in colorectal cancer, development of novel diagnostic and preventive methods for metastasis is highly desirable. However, the molecular mechanism of the metastatic phenotype has not been well elucidated. In this regard, we searched for metastasis-related proteins in colorectal cancer by analyzing the differential expression of proteins between primary and metastasis focus-derived colorectal tumor cells using a proteomics-based study. In order to validate these candidate proteins, we analyzed the expression profile of these proteins in tissue microarray. As a result, Rho GDP-dissociation inhibitor (Rho GDI) was identified as a metastasis-related protein in colon cancer patients. Consequently, Rho GDI may be useful for a diagnostic or preventive target against colon cancer metastasis.
