AMPK agonist AICAR improves cognition and motor coordination in young and aged mice

ABSTRACT: Normal aging can result in a decline of memory and muscle function. Exercise may prevent or delay these changes. However, aging associated frailty may preclude physical activity. AMP-activated protein kinase (AMPK) is a transcriptional regulator important for muscle physiology. In the present study we investigated effects of AMPK agonist 5-aminoimidazole-4-carboxamide riboside (AICAR) on memory and motor function in young (2-month-old), aged (23-month-old) C57Bl/6 mice, and transgenic mice with muscle-specific mutated AMPK alpha-subunit (AMPK-DN). Mice were injected with AICAR (500 mg/kg) for 3 to 14 days and tested in the Morris water maze, rotarod and open field. Improved water maze performance and motor function was observed, albeit at longer duration of administration, in aged (14 da
