Novel Serum Biomarkers to Differentiate Cholangiocarcinoma from Benign Biliary Tract Diseases Using a Proteomic Approach

Figure 4

Visualization of protein interaction networks of the DE proteins. Inputting all DE proteins into STRING yielded a network visualizing linkages. The network nodes are proteins, whereas the edges represent the functional associations. Different line colors of edges represent different types of evidence for the association, as indicated in the figure.
