The liver is an important site of postprandial glucose disposal, accounting for the removal of up to 30% of an oral glucose load. The liver is also centrally involved in dietary lipid and amino acid uptake, and the presence of either or both of these nutrients can influence hepatic glucose uptake. The composition of ingested carbohydrate also influences hepatic glucose metabolism. For example, fructose can increase hepatic glucose uptake. In addition, fructose extraction by the liver is exceedingly high, approaching 50% to 70% of fructose delivery. The selective hepatic metabolism of fructose, and the ability of fructose to increase hepatic glucose uptake can, under appropriate conditions (eg, diets enriched in sucrose or fructose, high fructose concentrations), provoke major adaptations in hepatic metabolism. Potential adaptations that can arise in response to these conditions and putative mechanisms driving these adaptations are the subject of this review.

Diabetes mellitus (DM) is a complex metabolic disease characterized by hyperglycemia. Recently, the incidence of diabetes has increased exponentially, and it is estimated to become the seventh leading cause of global mortality by 2030. Glucagon-like peptide-1 (GLP-1), a hormone derived from the intestine, has been demonstrated to exert remarkable hypoglycemic effects.

Weaning stress-induced diarrhea is a serious issue in pig production. This study aimed to evaluate the potential of glucose oxidase (GOD) as an antibiotic substitute to alleviate diarrhea and improve gut health in weaned piglets. According to a randomized complete block design, 250 piglets weaned around 21 d of age were allocated into 5 groups (5 replicates/group), which received a basal diet without or with supplemental 200 mg/kg antibiotic, 500, 1000 and 2000 U/kg GOD, respectively.

Fluorinated liquid crystal monomers (FLCMs) are widely employed in liquid crystal display (LCD) panels. As emerging environmental contaminants with persistent, bioaccumulative, and toxic properties, FLCMs were proven to accumulate in liver, raising great concern regarding potential hepatotoxicity. 1-Ethoxy-2,3-difluoro-4-(trans-4-propylcyclohexyl) benzene (EDPrB), as one representative FLCM, was chosen to investigate the hepatotoxicity in adult zebrafish (Danio rerio) at environmentally relevant concentrations (1, 10, and 100 μg/L) with long-term exposure (21 days).

Enhanced hepatic gluconeogenesis plays an important role in exercise glucose homeostasis when hepatic glycogen stores are depleted. Livers from trained animals demonstrate greater rates of gluconeogenesis in the presence of elevated substrate with and without hormonal stimulation. Training has been reported to have a particularly profound impact on norepinephrine-stimulated gluconeogenesis, but this was only demonstrated in the presence of other gluconeogenic hormones.

Background And Aims: Limited data link manufactured sweeteners impact on metabolic dysfunction-associated steatotic liver disease (MASLD). We aimed to evaluate the effects of manufactured sugars (L-glucose) compared to natural sugars (D-glucose) on phenotype, molecular and metabolic changes in mice models fed with either regular diet (RD) or high fat diet (HFD).
Methods: C57BL/6 mice fed 16-weeks with either RD; 70% carbohydrate or HFD; 60% fat, with or without additional glucose (Glu, at 18% w/v) to drinking tap water at weeks 8-16; of either natural (D-Glu) or manufactured (L-Glu) sugars.
