High-Fructose Diet and Chronic Unpredictable Stress Modify Each Other's Neurobehavioral Effects in Female Rats.

ABSTRACT: A pervasive exposure to stressors and the consumption of fructose-containing beverages usually go hand-in-hand in everyday life. In contrast to their metabolic outcomes, their impact on the brain and behavior is still understudied. We examined the behavioral response to a novelty (open field test), the expression of biochemical indicators of neuronal activity (Egr1 and FosB/ΔFosB), the synaptic potentiation (CaMKIIα and pCaMKII^Thr286), the synaptic plasticity (synaptophysin, PSD95, gephyrin, and drebrin), and the GABAergic system (parvalbumin and GAD67), along with the glucocorticoid receptor (GR) and AMPK, in the medial prefrontal cortex of female Wistar rats subjected to liquid fructose supplementation (F), chronic unpredictable stress (S), or both (SF) over 9 weeks.
