Space flight has many adverse effects on the physiological functions of astronauts. Certain similarities have been observed in some processes rodents and astronauts space, although there are also differences. These make helpful models for initial investigations into space-induced changes. This study uses a 3D-Clinostat to simulate microgravity explores role space flight-induced liver brain abnormalities by comparing changes gut microbiota, serum metabolites, function biochemistry tissues between simulated (SMG) group mice wild type (WT) mice. The study, based hematoxylin-eosin (HE) staining, 16S sequencing technology, non-targeted metabolomics analysis, shows that tissue morphology SMG is abnormal, structure microbiota metabolite profile imbalanced. Furthermore, using PICRUST 2 we predicted results indicate metabolism (including lipid metabolism, amino acid sugar etc.) disrupted, neurotransmitters hormone secretion, suggesting close relationship metabolic dysfunction dysfunction. Additionally, high similarity fecal transplant (FMT) mice, biochemical differences compared WT suggest induces imbalances which turn triggers function. Finally, through MetaMapp analysis Pearson correlation found valeric acid, more likely be key relates microgravity-induced abnormalities, disorders further induced or functional brain. significant practical application value deepening understanding adaptability living organisms environment.
