Functional associations between differentially expressed proteins in RC-77 T/E and RC-77 N/E cell lines. STRING (Search Tool for the Retrieval of Interacting Genes/Proteins) was used to visualize a network of functional associations between differentially expressed proteins. Interactions were limited to only those supported by experimental evidence, co-expression or co-occurrence data, and gene homology data. See Table 1 for the full names of proteins abbreviated here. Nodes centered on integrin beta-1, beta-catenin, and caveolin-1, suggesting these proteins have the potential to affect other proteins and may be involved in functional networks
