From: Identification of metabolite biomarkers in serum of rats exposed to chlorpyrifos and cadmium
Identification of serum metabolite biomarkers. After the 90-day experimental treatment, blood samples of the exposed rats were collected and the serum metabolites were determined by GC-MS. The summary diagram of serum biomarkers with AUC > 0.8 or AUC < 0.2 in rats treated with Cd (red), CPF (yellow), or both (green). The areas of red, green, and yellow circles with no overlap represent the unique biomarkers for treatments with Cd, CPF, and their combinations, respectively. The “+” and “−” in parentheses indicate that the biomarkers were increased or decreased in the treated rats, respectively. Abbreviations: Cd, cadmium; CPF, chlorpyrifos.
