Fig. 1.Effects of GSK-3 wt or GSK-3 S9A on
GSK-3 activity in rat hippocampal neurons overexpressing cdc42F28L.
Primary rat hippocampal neurons were transfected with pIRES-EGFP vectors
expressing cdc42F28L alone or together with pcDNA3.1 vectors carrying
GSK-3 wt, GSK-3 S9A, or empty pcDNA3.1 vectors (GSK-3
vector). Cells transfected with empty pIRES-EGFP vectors served as the controls
(Vector). At 72-h post-transfection, GSK-3 activity was measured. The
result of the Vector group was set as 1. Data are shown as mean SD.
