Abstract
Background: Alzheimer's disease (AD) represents the most prevalent form of dementia, characterized by memory loss, and is a complex, progressive neurodegenerative condition. Objectives: This study aimed to explore the impact of aerobic interval training (AIT) combined with Ginkgo biloba (GB) supplementation on passive avoidance memory function and the expression of the glial cell-derived neurotrophic factor (GDNF) gene in rats afflicted with AD. Methods: A total of forty-four male Wistar rats, each weighing approximately 250 ± 20 g, were maintained in a controlled environment at a specified temperature. Over 8 weeks (5 days per week), they underwent AIT and received GB supplements at a dosage of 100 mg/kg. The rats were randomly assigned into six groups: healthy control (HC) with 7 rats, AD control (AC) with 8 rats, amyloid-β (Aβ) injection plus GB supplement (Aβ + GB) with 8 rats, Aβ injection plus GB supplement plus AIT (Aβ + GB + AIT) with 8 rats, Aβ injection plus AIT (Aβ + AIT) with 8 rats, and sham surgery (SS) with 5 rats. The shuttlebox apparatus was utilized to assess the effect of Aβ on passive avoidance memory and to confirm disease induction. GDNF gene expression was measured using the qRT-PCR method. Results: The study found significant improvements in passive avoidance memory in the Aβ + AIT and Aβ + GB + AIT groups compared to the AC group after 8 weeks of AIT and GB supplementation (P = 0.02 and P = 0.000, respectively). Long-term memory performance was notably enhanced in the Aβ + GB + AIT group (P = 0.000). Additionally, GDNF expression significantly increased in the Aβ + GB + AIT and Aβ + GB groups in comparison to the AC group (P = 0.000 and P = 0.01, respectively). Conclusions: A synergistic effect of AIT and GB supplementation was observed, leading to an increase in GDNF gene expression and improvements in both passive avoidance memory and long-term memory in male rats with AD.
期刊介绍：
Accounts of Chemical Research presents short, concise and critical articles offering easy-to-read overviews of basic research and applications in all areas of chemistry and biochemistry. These short reviews focus on research from the author’s own laboratory and are designed to teach the reader about a research project. In addition, Accounts of Chemical Research publishes commentaries that give an informed opinion on a current research problem. Special Issues online are devoted to a single topic of unusual activity and significance.
Accounts of Chemical Research replaces the traditional article abstract with an article "Conspectus." These entries synopsize the research affording the reader a closer look at the content and significance of an article. Through this provision of a more detailed description of the article contents, the Conspectus enhances the article's discoverability by search engines and the exposure for the research.
