SynGAP enhances P38 signaling. (A) Neurons were either blocked or activated as above, except that the stimulation duration was increased to 10 min. Neurons were then immunolabeled with phospho-P38 (p-P38) and microtubule-associated protein 2 (MAP2) antibodies. (B) Quantification of phospho-P38 signal [average pixel intensity (API)] in neurons. ∗∗∗, P < 0.001. (C) Quantification of data (average pixel intensity) from phosphorylated P38 labeling of neurons derived from WT or SynGAP KO mice. Open bars, blocked; filled bars, activated. ∗, P < 0.01. (D) Quantification of phosphorylated P38 immunofluorescence from either blocked or activated neurons expressing eGFP, GFP-SynGAP, GFP-SynGAP_AL (GAP**), or siRNA (si_PAN) constructs. The intensity of transfected neurons was normalized to untransfected neighboring neurons. ∗∗∗, P < 0.001.
