The effect of arachidonic acid on PC12 cells. Cultured PC12 cells were subjected to various concentrations arachidonic acid (AA) (1–100 μM) for 24 h at 37°C. Number of viable cells was determined by MTT assay. The control was set to 100% survival. Data shown are means ± SEM (n = 3). Data were analyzed using one-way ANOVA and Neuman-Keuls’ test. Means with superscript ^a are significantly different at P < 0.05 comparing control.
