Fig. 3.

Main fatty acids in phosphatidylserine (PS) from cortex (A), hippocampus (B) and cerebellum (C) of 16 month-old wild-type (WT) and transgenic (Tg) mice on the oil blend diet (OB) or on the DHA diet. Results are represented as mean percentages of total fatty acids (Tg OB (n = 3), WT OB (n = 3), Tg DHA (n = 3), WT DHA (n = 3)) ± SEM. Analysis by GLC. Significant effect of diet, *p < 0.05, **p < 0.01, ***p < 0.001. The amounts of PS were, on average, 5.30 ± 0.20, 5.67 ± 0.49 and 4.99 ± 0.16 μg fatty acids/mg fresh weight for the cortex, hippocampus and cerebellum, respectively. There were no significant differences in the lipid amounts with diet or genotype.
