Arachidonic acid attenuates MPP ⁺ -induced cell death. PC12 cells were exposed to 500 μM MPP⁺ in the different doses of arachidonic acid (AA) (1–50 μM) for 24 h at 37°C. Number of viable cells was determined by MTT assay. The control was set to 100% survival. Data are expressed as means ± SEM (n = 3). Data were analyzed using one-way ANOVA and Neuman-Keuls’ test. Means with superscripts ^a and ^b are significantly different at P < 0.05 comparing control and 500 μM MPP⁺ only-treated groups, respectively.
