Effect of cacao supplementation on protein expression levels of neuroprotective enzymes. (a) Expression levels of PI3K; (b) the ratio of phospho-Akt/Akt levels; (c) expression levels of procaspase-3. Values represent mean ± SD, n = 8. ns: not significant; means for a variable with different letters (a, b) differ significantly (p < 0.05). C, control; G, d-galactose-induced aging; LC, d-galactose injection with 10% cacao powder mixed diet; HC, d-galactose injection with 16% cacao powder mixed diet.
