Fig. 6From: Gypenosides ameliorate memory deficits in MPTP-lesioned mouse model of Parkinson’s disease treated with L-DOPAEffects of GPS on CREB phosphorylation in the hippocampus. Phosphorylation of CREB (p-CREB), total CREB (t-CREB), and β-actin was examined as described in the Methods section. The value of the relative density ratio of the results is expressed in arbitrary units. * p < 0.05 compared with the control group. For further details, see Fig. 1 Back to article page
