The Neuroprotective Effects of Astragaloside IV against H₂O₂-Induced Damage in SH-SY5Y Cells are Associated with Synaptic Plasticity

Figure 3

Protein expression of PSD-95 and GAP-43 in SH-SY5Y cells under stress conditions. (a) Expression of PSD-95 under H₂O₂ (50 μmol·L⁻¹) treatment for 3 h after AS-IV (0.1∼0.4 μmol·L⁻¹) pretreatment for 2 h. (b) Expression of GAP-43 under H₂O₂ (50 μmol L⁻¹) treatment 3 h after AS-IV (0.1∼0.4 μmol L⁻¹) pretreatment for 2 h untreated, and H₂O₂-treatment cells were used as blank and negative controls, respectively.
