3/4/5-node composite FFL motif-specific sub-network (CFMSN). (A) A global view of 3/4/5-node composite FFL motif-specific sub-network (CFMSN). Orange triangle represents miRNA, green round represents TF and blue square represents gene. A line ending in a circle represents the regulatory relationship, while, a line ending in a “T” represents the repression relationship. (B–D) The examples of 3/4/5 node composite FFL. (E–H) The basic features of the network include degrees, clustering coefficients, topological coefficients and neighborhood connectivity of the network. TF: transcription factor; FFL: feed-forward loop.
