Immunomodulatory effect of low relative molecular mass seleno-aminopolysaccharide in Acanthopagrus schlegelii by hepatic metabolomics analysis

Abstract

Abstract: To investigate the immunomodulatory mechanism of low relative molecular mass seleno-aminopolysaccharide, a metabolomics method based on liquid chromatography-time-of-flight mass spectrometry (LC-TOF-MS) was used to analyze the endogenous metabolites changes in the liver of Acanthopagrus schlegelii. The potential biomarkers were screened using non-targeted mass spectrometry with the XCMS^plus software, and the related metabolic pathways were analyzed using MetaboAnalyst3.0 website. The results showed that the liver metabolites in the low relative molecular mass seleno-aminopolysaccharide-fed group were significantly different from those in the blank group. Also, 32 biomarkers were identified. Additionally, low relative molecular mass seleno-aminopolysaccharide could enhance the immune function of Acathopagrus schlegelii via amino acid, nucleotide, and nitrogen metabolism, aminoacyl-transfer ribonucleic acid (tRNA) biosynthesis, and other metabolic pathways. This study therefore provides a scientific basis for elucidating the immunoenhancement mechanism of low relative molecular mass seleno-aminopolysaccharide.
