Abstract:

Objective(s) The aim of this study was to evaluate the effects of regular exercise in preventing diabetes complication in the hippocampus of streptozotocin (STZ)-induced diabetic rat. Materials and Methods A total of 48 male wistar rats were divided into four groups (control, control exercise, diabetic and diabetic exercise). Diabetes was induced by injection of single dose of STZ. Exercise was performed for one hr every day, over a period of 8 weeks. The antioxidant enzymes (SOD, GPX, CAT and GR) and oxidant indexes with brain-derived neurotrophic factor (BDNF) protein and its mRNA and apoptosis were measured in hippocampus of rats. Results A significant decrease in antioxidant enzymes activities and increased malondialdehyde (MDA) level were observed in diabetic rats (P= 0.004). In response to exercise, antioxidant enzymes activities increased (P= 0.004). In contrast, MDA level decreased in diabetic rats (P= 0.004). Induction of diabetes caused an increase of BDNF protein and its mRNA expression. In response to exercise, BDNF protein and its mRNA expression reduced in hippocampus of diabetic rats. Conclusion Diabetes induced oxidative stress and increased BDNF gene expression. Exercise ameliorated oxidative stress and decreased BDNF gene expression.

Differential Effects of Resveratrol on the Expression of Brain-Derived Neurotrophic Factor Transcripts and Protein in the Hippocampus of Rat Brain

Background: The induction of brain-derived neurotrophic factor (BDNF) expression in the hippocampus has shown to play a role in the beneficial effects of resveratrol (RSV) on the learning and memory. The BDNF gene has a complicated structure with eight 5’ noncoding exons (I-IXa), each of which can splice to a common coding exon (IX) to form a functional transcript. Estrogens increase levels of ...

The Effect of Endurance Exercise Training on the Expression of Brain-Derived Neurotrophic Factor (BDNF) and Nerve Growth Factor (NGF) Genes of the Cerebellum in Diabetic Rat

Objective: Few studies have been conducted on variations of the central nervous system of diabetic patients and much fewer investigations done on the cerebellum of diabetes patients. The current research aims to investigate the effect of endurance training on neurotrophic factors affecting the cerebellum in the diabetic rat. Materials and Methods: This study is experimental.Twenty Wistar rat w...

Involvement of Mice Hippocampus Brain-derived Neurotrophic Factor in Diazinon-induced Depressive Behavior in Mice

Background: Diazinon (Dzn), an Organophosphorus (OP) pesticide, is extensively used in agriculture. Acetylcholinesterase inhibition is linked to OP toxicity, and there are major mental health concerns associated with the use of pesticides. The objective of this study was to assess the depressive behavior in an animal model following their exposure to Dzn and the effect on the Brain-Derived Neur...
