Identification of Potential Key Biomarkers and Immune Infiltration in Oral Lichen Planus

Figure 6

Protein-protein interaction network analysis was processed with Cytoscape, and different clusters were analyzed by MCODE. (a) The STRING database file was uploaded into Cytoscape v.3.7.2 to draw protein-protein interaction network, and different clusters analyzed by MCODE were noted with different colors. The significance of value was shown by the size of node. The color of the nodes showed the change of the DEGs, and the smaller the value is, the larger the diameter of node is. The color of the edge represented the value of combined score from 0.4 to 1, grey to dark. (b). The cluster 1 had 19 nodes and 171 edges, and the cluster score is 19.00. (c) The cluster 2 network had 9 nodes and 36 edges with 9.00 cluster score. (d) The cluster 3 network had 29 nodes and 89 edges with 6.357 cluster score, in which the upregulated nodes were colored in red, but the downregulated ones were colored in blue.
