Abstract
Traumatic brain injury (TBI), a progressive neurological disease caused by physical injury to the brain tissue, impacting its functions. This study employed metabolomics based on untargeted mass spectrometry method to examine plasma specimens from well-established mouse models with induced TBI (n = 6) and control mice (n = 6). The objective was to assess the metabolomics profile and the associated biochemical pathways in TBI. There was a noticeable segregation between TBI and reference groups (Q2 = 0.342, R2 = 0.993), according to orthogonal partial least square-discriminant analysis, indicating significant difference in metabolic expression. Moreover, 102 metabolites were significantly altered in TBI mice; 59 were upregulated, while 43 were downregulated in TBI mice. Correspondingly, the TBI model showed a significant dysregulation in number of key metabolic pathways, including metabolism of glycerophospholipids, linoleic acid, glycine, serine, threonine, pyrimidine, tryptophan, nicotinate and nicotinamide. Additionally, isoleucyl-asparagine, 2′-deoxyinosine triphosphate, diglycosyl diacylglycerols (25:0/26/2), and phosphatidylethanolamine (24:0/22:4) demonstrated excellent performance for TBI detection with an area under the curve ≥ 0.8. This study identified putative plasma biomarkers of TBI and highlighted the dysregulated biochemical pathways, providing valuable clinical insights into TBI research
