Biomarkers for predicting the severity of spinal cord injury by proteomic analysis.
Wei et al., Front Mol Neurosci 2023
DOI: 10.3389/fnmol.2023.1153230
New Findings:
The study identifies potential protein biomarkers for classifying the severity of spinal cord injury (SCI) in rat models. Using quantitative liquid chromatography-mass spectrometry (LC-MS/MS), the researchers found 154 differentially expressed proteins (DEPs) across mild, moderate, and severe SCI groups. Notably, proteins Fgg (Fibrinogen gamma chain), Fga (Fibrinogen alpha chain), and Fgb (Fibrinogen beta chain) were highlighted as significant nodes within the protein-protein interaction (PPI) network and were validated as upregulated in SCI samples through a parallel reaction monitoring (PRM) assay.
Importance:
This research is significant because it advances the understanding of SCI at the molecular level and proposes specific biomarkers that could be used to assess the severity of SCI. This could have important implications for diagnosis, treatment, and monitoring of SCI in clinical settings.
Contribution to Literature:
The study contributes to the current literature by providing a set of potential biomarkers for SCI severity, which were previously lacking. It also elucidates the involvement of the inflammatory response and the IL-17 signaling pathway in SCI, offering new insights into the pathophysiological mechanisms of SCI.
Numerical Details:
A total of 154 DEPs were identified, with 82 proteins showing similar expression patterns across different injury severities. The study specifically validated the upregulation of Fgg, Fga, and Fgb in SCI samples, suggesting their potential as biomarkers for SCI severity assessment.
