Psoralen is the main active component of Psoralea corylifolia and is used as a marker to assess its quality. The effects of psoralen on animals have been well characterized. However, the molecular pathway of its toxicity is not fully understood. In this study, the toxic effects of psoralen administration (60 mg/kg) for 7 days in Sprague–Dawley rats were observed. Serum biochemistry and liver histopathology were further investigated. Proton nuclear magnetic resonance was applied to characterize the metabolic profile of liver toxicity induced by psoralen and to find changed metabolites in rat serum and liver. It was revealed that visceral coefficients and serum biochemistry indexes were significantly changed in rats with psoralen-induced liver injury. Furthermore, the histopathological examination exhibited that the liver might be the target organ for psoralen. Metabolic analysis of both serum and liver samples further proved the liver was the target of toxicity of psoralen. Multivariate analysis identified...

Introduction: Erythromycin (ERY) is known to induce hepatic toxicity which mimics other liver diseases. Thus, ERY is often used to produce experimental models of drug-induced liver-toxicity. The serum metabolic profiles can be used to evaluate the liver-toxicity and to further improve the understanding of underlying mechanism. Objective: To establish the serum metabolic patterns of Erythromycin induced hepatotoxicity in albino wistar rats using 1 H NMR based serum metabolomics. Experimental: Fou...

Metabolomics has emerged as an essential tool for studying metabolic processes, stratification of patients, as well as illuminating the fundamental metabolic alterations in disease onset, progression, or response to therapeutic intervention. Metabolomics materialized within the pharmaceutical industry as a standalone assay in toxicology and disease pathology and eventually evolved towards aiding in drug discovery and pre-clinical studies via supporting pharmacokinetic and pharmacodynamic charact...

ABSTRACTIntroduction: The metabolic profile is a direct signature of phenotype and biochemical activity following any perturbation. Metabolites are small molecules present in a biological system including natural products as well as drugs and their metabolism by-products depending on the biological system studied. Metabolomics can provide activity information about possible novel drugs and drug scaffolds, indicate interesting targets for drug development and suggest binding partners of compounds...

Psoralen is a major active component of Psoralea corylifolia. In the present study, we analyzed psoralen-induced changes in human breast cancer MCF-7/ADR cells and investigated the underlying mechanisms of the anticancer effect on MCF-7/ADR cells. We measured cell viability by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay to evaluate the cytotoxicity and multidrug resistance (MDR) reversal activity of psoralen. The cell cycle distribution and apoptosis, accumulation an...

Due to the potential risk of accidental exposure to gamma radiation, it’s critical to identify the biomarkers of radiation exposed creatures. In the present study, NMR based metabolomics combined with multivariate data analysis to evaluate the metabolites changed in the C57BL/6 mouse spleen after 4 days whole body exposure to 3.0 Gy and 7.8 Gy gamma radiations. Principal component analysis (PCA) and orthogonal projection to latent structures analysis (OPLS) are employed for classification and id...

Pancreatic islet failure, involving loss of glucose-stimulated insulin secretion (GSIS) from islet β cells, heralds the onset of type 2 diabetes (T2D). To search for mediators of GSIS, we performed metabolomics profiling of the insulinoma cell line 832/13 and uncovered significant glucose-induced changes in purine pathway intermediates, including a decrease in inosine monophosphate (IMP) and an increase in adenylosuccinate (S-AMP), suggesting a regulatory role for the enzyme that links the two m...

When quantifying information in metabolomics, the results are often expressed as data carrying only relative information. Vectors of these data have positive components, and the only relevant information is contained in the ratios between their parts; such observations are called compositional data. The aim of the paper is to demonstrate how partial least squares discriminant analysis (PLS-DA)—the most widely used method in chemometrics for multivariate classification—can be applied to compositi...

Fructus Psoraleae (FP), widely used in traditional medicine, is increasingly reported to cause serious hepatotoxicity in recent years. However, the main toxic constituents responsible for hepatotoxicity and the underlying mechanisms are poorly understood. In the present study, psoralen, a main and quality-control constituent of FP, was intragastrically administered to Sprague-Dawley rats at a dose of 60 mg/kg for 1, 3 and 7 days. Blood and selected tissue samples were collected and analyzed for ...

Abstract Silica nanoparticles (SiNPs) have become one of the most widely studied nanoparticles in nanotechnology for environmental health and safety. Although many studies have devoted to evaluating the hepatotoxicity of SiNPs, it is currently impossible to predict the extent of liver lipid metabolism disorder by identifying changes in metabolites. In the present study, 40 male Sprague-Dawley (SD) rats were randomly divided into control group and 3 groups with different doses (1.8 mg/kg body wei...

Cantharidin (CTD), a compound secreted from Mylabris species, exhibits strong antitumor properties; however, hepatotoxicity restricts its clinical application. The mechanism by which CTD induces toxicity remains unclear. In the present study, the hepatotoxicity of CTD in the rat was investigated using a metabolomic approach combined with conventional pathology methods. A total of 30 rats were intragastrically treated with two doses of CTD (0.75 and 1.5 mg/kg) for 15 days to evaluate hepatotoxici...

Isofenphos-methyl (IFP), a chiral organophosphorus pesticide, is one of the main chemicals used to control underground insects and nematodes. Recently, the use of IFP on vegetables and fruits has been prohibited due to its high toxicity. In this study, we investigated the enantioselective distribution and metabolism of IFP and its metabolites, namely, isofenphos-methyl oxon (IFPO) and isocarbophos oxon (ICPO), in male Sprague Dawley (SD) rats. Forty eight hours (48 h) after exposure, ICPO was th...

Abstract Furanocoumarins are a class of natural compounds produced by several plants, including those consumed by humans. They have been used medicinally in eastern countries for ages. Given the growing body of evidence about their anticancer potential and observations that naturally occurring compounds potentiate the antitumor activity of chemotherapeutics, more attention is paid to elucidation of the nature of furanocoumarins and the possibility of using thereof in practice. The general mechan...
