Metabolomics provides insights into acceleration of bone healing in fractured patients with traumatic brain injuries

While clinical surveys have frequently reported that patients with traumatic brain injuries (TBIs) and comorbidities experience faster healing, the underlying mechanisms have been investigated but remain unclear. As a comprehensive comparison and analysis of the metabolic characteristics of these tw...

Description
Summary:While clinical surveys have frequently reported that patients with traumatic brain injuries (TBIs) and comorbidities experience faster healing, the underlying mechanisms have been investigated but remain unclear. As a comprehensive comparison and analysis of the metabolic characteristics of these two pathologies have not been undertaken, we developed a rat model of fracture and TBI and collected serum samples for metabolomic analysis using ultra‐high performance liquid chromatography–quadrupole time‐of‐flight MS (UHPLC–Q‐TOF/MS). In total, we identified 40 differential metabolites and uncovered related pathways and potential mechanisms, including aminoacyl‐transfer RNA biosynthesis; differential amino acids such as leucine, cholylhistidine, aspartyl‐lysine; and related lipid metabolism, and discussed their impacts on bone formation in detail. This study highlights that the UHPLC–Q‐TOF/MS–based metabolomics approach offers a better understanding of the metabolic links between TBI and accelerated bone recovery.
