Fig. 4From: In silico analysis of differentially expressed genesets in metastatic breast cancer identifies potential prognostic biomarkersIdentification of hub genes in PPI networks. A,B The PPI networks among the differentially over-expressed (A) and under-expressed genes (B) were exported separately and entered into Cytoscape, the network analysis tool. The top ten hub genes (A, hub_oe; B, hub_ue) are ranked according to their number of interactorsBack to article page
