Figure 2.

The intracellular S100B levels of 1321N1 astrocytic cells exposed to beta-amyloid (Aβ), valproic and arundic acids. The S100B concentration was measured in cell lysate via the ELISA method. Data were analyzed using one-way analysis of variance (ANOVA) followed by the Tukey’s test. P-value of lower than 0.05 was the significant level. Aβ: beta-amyloid peptide25-35 (200 µM), AA: arundic acid (50 µM), Val0.5: valproic acid (0.5 mM), Val1: valproic acid (1 mM). **: P-value of <0.001 compared to the beta-amyloid-treated group and ‡: P-value of <0.001 compared to the control-treated group
