Figure 4. Protein-protein interaction (PPI) network and modules analysis. (A) PPI network of differentially expressed RBPs; (B) 3 critical modules from PPI network. The outer circle is critical module 1, the middle circle is critical module 2, and the inner circle is critical module 3. Red circles: up regulation RBPs; Green circles: down regulation RBPs.
