Fig. 4From: Identification of prognosis-related genes and construction of multi-regulatory networks in pancreatic cancer microenvironment by bioinformatics analysisModule mining of PPI networks. The PPI network data from STRING was further analyzed by Cytoscape. Circles and lines represented genes and the interaction of proteins between genes, respectively. The color of a node in the network reflected the log (FC) value of the Z score of gene expression. The size of a node indicated the number of interacting proteins with the designated proteinBack to article page
