Metabonomics Study on the Acute Toxicity of Toad Venom
摘要
Abstract
The metabonomics method coupled with electrocardiogram were applied to the study on the acute toxicity of toad venom. The profiles of serum samples were obtained with ultra performance liquid chromatography coupled with time-of-flight mass spectrometry(UPLC/TOF-MS). The data were firstly processed with the software Markerlynx and then analyzed with the principal components analysis (PCA) and orthogonal partial least squares discriminate analysis(OPLS-DA). The potential biomarkers were screened out according to the VIP( variable importance in projection) value and identified with t-fit, database and corresponding reference standards. The metabolites of significant intergroup differences were finally found to be li-pids related to myocardial energy metabolism. According to the biological functions of the obtained potential biomarkers, it was deduced that the heart injury may be induced by disturbing lipid metabolism through hampering the re-acylation of free fatty acid or activating protein kinase pathway. This study provides a new approach to discover the underlying mechanism of toad venom toxicity.关键词
