MAP4K4 signaling is mediated by AcSDKP in a FGFR1/FRS2-dependent manner. (a and b) HMVECs were treated with N-FGFR1 for 48 h in the presence or absence of FGF2 or AcSDKP. P-MAP4K4 levels were analyzed by western blot. Densitometric analysis of P-MAP4K4 levels normalized to MAP4K4. For each group, n=3 were analyzed. (c and d) HMVECs were transfected with FRS2 siRNA for 48 h with or without FGF2 or AcSDKP treatment. P-MAP4K4 levels were analyzed by western blot. Densitometric analysis of P-MAP4K4 levels, normalized to MAP4K4. A total of n=3 from each group were analyzed
