Exposure to aflatoxins causes liver fibrosis and hepatocellular carcinoma posing a significant health risk for human populations and livestock. To understand the mammalian systems responses to aflatoxin-B1 (AFB1) exposure, we analyzed the AFB1-induced metabonomic changes in multiple biological matrices (plasma, urine, and liver) of rats using (1)H NMR(More)
Obesity is a condition resulting from the interactions of individual biology and environmental factors causing multiple complications. To understand the system's metabolic changes associated with the obesity development and progression, we systematically analyzed the dynamic metabonomic changes induced by a high-fat diet (HFD) in multiple biological(More)
Faecal metabonomic NMR analysis plays an essential role in investigating the interactions between mammalian metabolism and symbiotic gut microbiota. However, the faecal metabolite extraction method remains to be optimised and standardised to take into consideration signal-to-noise ratios, pH and chemical shift consistency. In the current investigation, we(More)
Diabetes mellitus is a complex polygenic disease caused by gene-environment interactions with multiple complications, and metabonomic analysis is crucial for pathogenesis, early diagnosis, and timely interventions. Here, we comprehensively analyzed the dynamic metabolic changes in rat urine and plasma, which were induced by the well-known diabetogenic(More)
Obesity is a worldwide epidemic and a well-known risk factor for many diseases affecting billions of people's health and well-being. However, little information is available for metabolic changes associated with the effects of obesity development and interventions on cardiovascular and reproduction systems. Here, we systematically analyzed the effects of(More)
Inflammation is closely associated with pathogenesis of various metabolic disorders, cardiovascular diseases, and cancers. To understand the systems responses to localized inflammation, we analyzed the dynamic metabolic changes in rat plasma and urine associated with the carrageenan-induced self-limiting pleurisy using NMR spectroscopy in conjunction with(More)
Obesity resulting from interactions of genetic and environmental factors becomes a serious public health problem worldwide with alterations of the metabolic phenotypes in multiple biological matrices involving multiple metabolic pathways. To understand the contributions of gut microbiota to obesity development, we analyzed dynamic alterations in fecal(More)
Extreme low salinity influences normal crab growth, morphogenesis, and production. Some individuals of swimming crab Portunus trituberculatus have, however, an inherent ability to adapt to such a salinity fluctuation. This study investigated the dynamic metabolite alterations of two P. trituberculatus strains, namely, a wild one and a screened (low-salinity(More)
Prostaglandin E2 receptor 4 (EP4) is one of the receptors for prostaglandin E2 and plays important roles in various biological functions. EP4 antagonists have been used as anti-inflammatory drugs. To investigate the effects of an EP4 antagonist (L-161982) on the endogenous metabolism in a holistic manner, we employed a mouse model, and obtained metabolic(More)
