Figure 1. Pituitary adenylate cyclase activating peptide (PACAP) 38 protects cortical neurons against sodium nitroprusside (SNP) treatment.
Data represents cell survival as measured by MTT assay and expressed as percent of untreated control (100%). Data are means ± SEM of three or 4 experiments performed in triplicate. One-way Analysis of variance was performed followed by Newman-Keuls Multiple comparison test. A. SNP evokes neuronal cell death. Cortical neurons were treated with a range of SNP concentrations (10 μM – 1 mM) for 4 h. *** p <0.001 vs control. B. Cortical neurons were treated with 1 mM SNP and co-incubated with a range of PACAP38 concentrations (25 nM – 300 nM for 4 h). a p<0.01 vs control, ** p<0.01 vs 1 mM SNP. C. Cortical neurons were exposed to PACAP38 at the time of SNP (1 mM, 4 h) treatment (Co-treatment), or 1 h prior (Pre-treated), or 1 h after SNP treatment (Post-treatment).
