Fructose increases cellular ATP levels and the release of dopamine from the Neuro 2a cells. The cellular ATP contents (A), levels of dopamine in culture medium (B) and cell viability (C) of the N2a cells determined at 72 hours after exposure to different concentrations of fructose (0, 12.5, 25, or 50 μM). Values are mean ± SEM of quadruplicate analyses. *P < 0.05, **P < 0.01 versus control (0 μM fructose) group in the post hoc Tukey’s multiple range analysis.
