Natural taurine promotes apoptosis of human hepatic stellate cells in proteomics analysis

Figure 4 Network diagram of functional categorization of differentially expressed proteins. The categories in this tree structure fully correspond to the 3 categories in Table 2 and the depth of color ranging from light to dark gray indicates the significance level of FDR in Table 2. Gray nodes represent significantly enriched GO terms and white nodes signify GO terms that have a parent/child relationship with gray nodes. Connecting lines between nodes construct a directional hierarchy of the GO terms.
