Serum metabolic profiles of all subjects were analyzed using ultra-performance liquid chromatography coupled with quadruple-time-of-flight mass spectrometry. The metabolic characteristics of the ST/KDP subjects were determined, and the corresponding biomarkers were predicted. The metabolomics data from the healthy → ST/KDP subjects were collected for further verification.RESULTS: Twelve metabolites in the ST/KDP subjects were different from those of the healthy control subjects. Of these metabolites, according to the prediction, except for octanoic acid, other metabolites might characterize ST/KDP. Ten metabolites at the outcome ST/KDP stage were different from those at the initial(control) stage. Through the comparison of these metabolites with the predicted metabolites, five common metabolites, including upregulated glutamate, serotonin, oroticacid and 8-oxoguanine, as well as downregulated taurine, were found. These common metabolites were significantly associated with canonical pathways including calcium signaling, γ-aminobutyric acid(GABA) receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.CONCLUSION: The metabolic pathogenesis in ST/KDP subjects was characterized by upregulated glutamate, serotonin, orotic acid and 8-oxoguanine, as well as downregulated taurine, additionally, perturbations of calcium signaling, GABA receptor signaling, purine and pyrimidine biosynthesis, taurine biosynthesis, and serotonin receptor signaling.展开更多
