Schematic representation of asTF signaling pathway. EC indicates endothelial cell; P-FAK, phosphorylated focal adhesion kinase; PI3K, phosphatidylinositol 3-kinase; Akt; MEK, mitogen-activated protein kinases; ERK, extracellular-signal-regulated kinases; HIF-1α, hypoxia-inducible factor-1α (inducible); HIF-1β, hypoxia-inducible factor-1β (constitutive); Ub, ubiquitin; VEGF165, vascular endothelial growth factor isoform 165 (soluble).
