Ingenuity pathway analysis of a treatment response-induced, IL13-dependent cluster identified key regulatory genes TGF-β1 and JUNB. Eight of the network proteins were regulated by TGF-β1, which in turn is activated or induced by THBS1, MMP14 and IL13 in a positive-feedback loop. Proteins are represented by nodes, and edges indicate all interactions other than coexpression. Nodes of dark blue indicate IL13-dependent expression (i.e., genes that are induced by treatment only in the presence of IL13).
