a STRING analysis of proteins increased in non-metastatic and metastatic stages of colon cancer (UII). b STRING analysis of proteins decreased in non-metastatic and metastatic stages of colon cancer (UDD). Proteins are shown as nodes and the color of each link defined the type of evidence available for the interaction between two proteins (e.g. blue: co-occurrence, black: co-expression, purple: experimental, aqua: databases, green: text mining and light blue is homology.)
