Previous studies highlighted bisphenol S (BPS), an industrial chemical responsible for harmful effects comparable to its congener substance bisphenol A (BPA). Accounted for various adversities to biological functions, it could alter the expression of endogenous metabolites in many metabolic processes. The study was aimed to investigate the altered metabolites in hyperglycemic condition triggered by sub-chronic exposure of BPS in serum and urine samples of Wistar rats. Invaded effects of hyperglycemia due to BPS exposure on Wistar rats were investigated by oral glucose tolerance test (OGTT) and insulin tolerance test (ITT). Metabolomic profiling of serum and urinary metabolites was done by gas chromatography-mass spectrometry (GC-MS) analysis. The metabolomics data were represented by one way ANOVA, principal component analysis (PCA), partial least squares discriminant analysis (PLS-DA) along with the mapping of perturbed metabolic pathways. The OGTT and ITT showed increased levels of glucose in treated animals with median and high doses, indicating the manifestation of hyperglycemia. The metabolomic profiling of serum and urine revealed BPS could cause consequential metabolomic perturbation mainly of amino acids, sugars, and organic acids. Furthermore, the extrapolation of Kyoto Encyclopedia of Genes and Genomes (KEGG) based systematic analysis helped to monitor the altered pathways, including amino acids, glycolysis, pyruvate metabolism, etc., which were provoked due to BPS exposure. The overview of the perturbed metabolite profiling in rats promisingly showed early diagnostic markers of hyperglycemic condition triggered due to the BPS exposure. Findings from this study will be helpful towards the exploration of mechanistic insights of several disturbed pathways.
