NF-κB and STAT1 network. Representative transcription regulatory networks based on differentially expressed data in patients with or without hematopoietic-cell transplantation using MetaCore™ network software and the Analyze Network algorithm. Two representative networks are shown: (3A) the NF-κB network and (3B) the STAT1 network. NF-κB and STAT1 are acute-phase responsive factors which are involved in the regulation of complement activation and,coagulation as well as their intercommunication. Red circles in the right corner of a gene indicate up-regulation and blue circles down-regulation.
