Beneficial Effects of Exercise Pretreatment in a Sporadic Alzheimer's Rat Model

PURPOSE This study aimed to examine the effects of swimming exercise pretreatment on a streptozotocin (STZ)-induced sporadic Alzheimer's disease rat model and provide an initial understanding of related molecular mechanisms. METHODS Male 2.5-month-old Sprague-Dawley rats were divided into the following 4 groups: a) control, b) swim + vehicle, c) STZ without swim, and d) swim + STZ. The Barnes Maze task and Novel Object Recognition test were used to measure hippocampus-dependent spatial learning and working memory, respectively. Immunofluorescence staining, Western blot analysis, ELISA analysis and related assay kits were used to assess synaptic proteins, inflammatory cytokines, total antioxidant capacity, antioxidant enzymes, amyloid-beta (Aβ) production and tau hyperphosphorylation. RESULTS Behavioral tests revealed that exercise pretreatment could significantly inhibit STZ-induced cognitive dysfunction (p
