Fig. 7. Model of the paracrine signaling network influenced by deletion of
Klf5. mRNAs that were significantly altered in lungs from
Klf5
/
mice were subjected to literature
mining to identify potential functional associations and regulatory
relationships using Pathway Studio 5.0 (Ariadne Genomics). KLF5 influenced the
expression of genes previously associated with various signaling pathways,
including those regulated by PDGF, FGF and TGFβ. mRNAs increased in
Klf5
/
mice are framed in red, those
decreased are framed in green. Each line indicates a regulatory relationship
between gene nodes based upon literature references. Regulatory relationships
are denoted by line colors and patterns: purple lines represent binding; blue
lines represent regulation of expression; the gray lines represent
`regulation'; and arrows with a plus indicate positive regulation.
