Pathway analysis. The number of proteins associated with canonical signaling pathways as defined by Ingenuity Pathway analysis is shown. Only pathways with five or more protein associations are shown. ERK, extracellular signal-regulated kinase; MAPK, mitogen-activated protein kinase; PI3K, phosphatidylinositol 3-kinase; VEGF, vascular endothelial growth factor; SAPK, stress-associated protein kinase; JNK, c-Jun NH2-terminal kinase; GABA, γ-aminobutyric acid.
