Figure 2 -. Protein-protein interactions of the 225 differentially expressed proteins presenting gradual increased/decreased expression levels from MNT to MPT to MLN, predicted by STRING database v. 10.5. The colors of the nodes correspond to different clusters and inter-cluster edges are represented by dashed-lines. MNT, male-non-tumor breast tissue; MPT, male-primary breast tumor; MLN, male-axillary metastatic lymph node.
