Impact of aerobic exercise on brain metabolism: Insights from spatial metabolomic analysis

Background

Exercise is acknowledged for its beneficial effects on brain health; however, the intricate underlying molecular mechanisms remain poorly understood. Aims: This study aimed to explore aerobic exercise-induced metabolic alterations in the brain. Methods: We conducted an eight-week treadmill running exercise program in two-month-old male C57/BL6J mice. Body weight, serum lipid, glucose levels, and spatial cognition were measured. Spatial metabolomic analysis was performed to compare the metabolomic profiles across different brain regions. Immunohistochemical methods were used to compare the expression of carnitine palmitoyltransferase 1c (CPT1c). Results: Exercise induced significant changes in the analysed metabolomic profiles. There were 904 differentially expressed metabolites (DEMs) detected in the whole brain section. Notable alterations in lipid profiles were observed, and among the 292 lipids detected, there were 74 (25.34 %), 85 (29.11 %), and 78 (26.71 %) lipids differentially expressed in the hippocampus, thalamus, and hypothalamus of the Exe group, respectively. Lipid metabolism related pathways and enzymes were also altered, with L-carnitine and CPT1c upregulated in the three regions (p<0.05), and epinephrine levels decreased in the hippocampus (p<0.05). Furthermore, the vitamin B6 metabolism pathway was altered in the hypothalamus.

Conclusions

This study highlighted the significant changes in lipid metabolism induced by involuntary exercise in the brains of young male mice. Exercise also altered epinephrine levels and the vitamin B12 metabolic pathway in specific brain regions, which indicated the multifaceted effects of exercise on the brain.

期刊介绍： Behavioural Brain Research is an international, interdisciplinary journal dedicated to the publication of articles in the field of behavioural neuroscience, broadly defined. Contributions from the entire range of disciplines that comprise the neurosciences, behavioural sciences or cognitive sciences are appropriate, as long as the goal is to delineate the neural mechanisms underlying behaviour. Thus, studies may range from neurophysiological, neuroanatomical, neurochemical or neuropharmacological analysis of brain-behaviour relations, including the use of molecular genetic or behavioural genetic approaches, to studies that involve the use of brain imaging techniques, to neuroethological studies. Reports of original research, of major methodological advances, or of novel conceptual approaches are all encouraged. The journal will also consider critical reviews on selected topics.
