Abstract

Ageing is a complex physiological process characterized by a gradual decline in cell, tissue and organ function. Consequently, ageing is a major risk factor for cardiovascular disease, diabetes and neurodegenerative disorders. Altered nervous system function can lead to behavioural or psychological disorders. Recent research has shown that alpha ketoglutarate (AKG) is a key intermediate in the Krebs cycle that extends the lifespan of adult animal organisms. The objective of this study was to assess the effect of AKG on the behaviour of laboratory mice in an open field test. The Na-AKG form was found to enhance perceptual-motor exploration in the mice (expressed as the number of rearings), and at the same time to suppress anxiety-related behaviour.

α -酮戊二酸酯(AKG)对衰老实验小鼠行为的影响
衰老是一个复杂的生理过程,其特征是细胞、组织和器官的功能逐渐下降。因此,衰老是心血管疾病、糖尿病和神经退行性疾病的主要风险因素。神经系统功能的改变可导致行为或心理障碍。最近的研究表明,α酮戊二酸(AKG)是克雷布斯循环的关键中间体,可以延长成年动物生物体的寿命。本研究的目的是在野外试验中评估AKG对实验室小鼠行为的影响。发现Na-AKG形式增强了小鼠的感知运动探索(以饲养次数表示),同时抑制了焦虑相关行为。
