Abstract

Intermittent fasting (ImF) is known to reduce oxidative stress and affects adult neurogenesis in the hippocampal dentate gyrus. However, it is unknown how ImF affects endogenous antioxidants expressions, cell proliferation, and neuroblast differentiation and their dendrite remodeling over 3 months in the dentate gyrus of adult gerbils. The present study subjected 6‑month old male gerbils to a normal diet or alternate‑day ImF for 1, 2 and 3 months. Changes in body weight were not significantly different between gerbils fed a normal diet and on ImF. The present study also investigated the effects of ImF on antioxidant enzymes [superoxide dismutase (SOD)‑1, SOD2 and catalase] using immunohistochemistry, and endogenous cell proliferation, neuroblast differentiation and neuroblast dendrite complexity by using Ki67 (a cell proliferation marker) and doublecortin (neuroblast differentiation marker) immunohistochemistry in the dentate gyrus. SOD1, SOD2 and CAT immunoreactivities were shown in cells in the granule cell and polymorphic layers. SOD1, SOD2 and catalase immunoreactivity in the cells peaked at 2, 1 and 1 month, respectively, following ImF. Cell proliferation was ~250, 129 and 186% of the control, at 1, 2 and 3 months of ImF, respectively. Neuroblast differentiation was ~41, 32 and 12% of the control, at 1, 2 and 3 months of ImF, respectively, indicating that dendrites of neuroblasts were more arborized and developed at 3 months of ImF. Taken together, these results indicate that ImF for 3 months improves endogenous SOD1, SOD2 and catalase expressions and enhances cell proliferation, and neuroblast dendrites complexity and maturation in the adult gerbil dentate gyrus.
