A, EC were transfected with 100 nM Rictor siRNA or GL-2 control siRNA. After 48 h EC were trypsinized, kept in suspension (Suspend) for 30 min and then replated on poly-L-lysine (Lys) or fibronectin (FN) coated dishes for 10 min. EC were lysed and immunoblotted with antibody to ERK Thr202/Tyr204, ERK and Rictor. Data is representative of three independent experiments. B, EC were transfected with 100 nM Rictor siRNA or GL-2 control siRNA for 48 h. EC were stimulated with 1 ng/mL or 20 ng/mL bFGF for 10 or 30 min. EC were lysed and immunoblotted with antibodies to ERK Thr202/Tyr204, ERK, Rictor and Vinculin. Data is representative of three independent experiments.
