ILK and head and neck squamous cell carcinoma: In the integrin signaling networks of the HNSCC transcriptome, we identified several repressed inter-modular hubs: ACTN2, CAPN3 and TTN in Pre and TvN; and ILK, RHO-G and VCL in Meta. GRB2, ITGA5, ITGB6, ITGB7 and MAPK8 were distinguished as topologically significant hubs in the TvN interacting networks.
