ABSTRACT
BACKGROUND:
The metabolic profile of human aortic tissues is of great importance. Among the analytical platforms utilized in metabolomics, LC-MS provides broad metabolome coverage. The non-targeted metabolomics can comprehensively detect the entire metabolome of an organism and find the metabolic characteristics that have significant changes in the experimental group and the control group and elucidate the metabolic pathway concerning the recognized metabolites. Employing non-targeted metabolomics is helpful to develop biomarkers for disease diagnosis and disease pathology research; for instance, Aortic aneurysm (AA) and Aortic dissection (AD).AIM:
This study sought to describe the non-targeted analysis of 18 aortic tissue samples, comparing between AA and AD. MATERIAL &METHODS:
Our experimental flow included dividing the samples into (AA, nine samples) and (AD, nine samples), SCIEX quadrupole timeofflight tandem mass spectrometer (TripleTOF) 6600+ mass spectrometer data refinement, MetDNA database analysis, and pathway analysis. We performed an initial validation by setting quality control parameters to evaluate the stability of the analysis system during the computer operation. We then used the repeatability of the control samples to examine the stability of the instrument during the entire analysis process to ensure the reliability of the results.RESULTS:
Our study found 138 novel metabolites involved in galactose metabolism.DISCUSSION:
138 novel metabolites found in this study will be further studied in the future.CONCLUSION:
Our study found 138 novel metabolites between AA and AD, which will provide viable clinical data for future studies aimed to implement galactose markers in aortic tissue analysis.Palavras-chave
