Induction of caspases-3 and -8, but not caspase-9, activity in cellular extracts of differentiated PC12 cells exposed to either palmitic or stearic acid complexed (2 : 1) with BSA. (a) Palmitic acid. (b) Stearic acid. Data represent the mean ± SD of three independent experiments performed in triplicate. # indicates significance of p < 0.05 in a two-sample t-test comparing caspase-8 activity at 3 h with that at 6 h. Data passed a test for normality and equality of variance.
