Integrated network analysis of transcriptomic and protein-protein interaction data in taurine-treated hepatic stellate cells

Figure 4 Functional sub-modules in the protein-protein interaction network of differentially expressed genes in the taurine-treated hepatic stellate cells. Red coloring represents up-regulated genes; green coloring represents down-regulated genes; purple coloring represents genes from database; the shade is related to the change fold (darker colors indicate more apparent differences).
