Figure 3 PPI network of prognostic m6A-related genes constructed using STRING database (V11). In the diagram, genes are represented by nodes and their interactions are linked by lines. Genes with red color and large circle had higher degree values in the network, while genes with yellow color and small circle had lower degrees in the network. Cytoscape software (V3.5) was applied to visualize and analyze biological networks and node degrees of the 146 candidate genes.
