FGF2/FGFR1 mediates MAP4K4 signaling in endothelial cells. (a) Immunofluorescence microscopy analysis of P-MAP4K4 expression following FRS2 siRNA or TGFβ2 treatment. For each slide, images of six different fields of view at × 400 magnification were evaluated. The scale bar is 60 μm in each panel. (b and c) HMVECs were treated with N-FGFR1 for 48 h or FGF2 for 24 h. The P-MAP4K4 levels were analyzed by western blot
