Project description:Non-alcoholic fatty liver disease (NAFLD) is characterized by the accumulation of lipid droplets (LD) in hepatocytes. NAFLD development and progression is associated with an increase in hepatic cholesterol and decreased autophagy and lipophagy flux. Previous studies have shown that the expression of lysosomal acid lipase (gene=LIPA, protein=LAL), which can hydrolyze both triglyceride and cholesteryl esters, is inversely correlated with the severity of NAFLD. In addition, ablation of LAL activity results in profound NAFLD. Based on this, we predicted that overexpressing LIPA in the livers of mice fed a Western diet (FPC) would prevent the development of NAFLD. As expected, mice fed the FPC diet exhibited numerous markers of NAFLD including hepatomegaly, lipid accumulation, and inflammation. Unexpectedly, LAL overexpression did not attenuate steatosis and had only minor effects on neutral lipid composition. However, LAL overexpression exacerbated inflammatory gene expression and infiltration of immune cells in mice fed the FPC diet. LAL overexpression also resulted in abnormal phagosome accumulation and lysosomal lipid accumulation depending upon the dietary treatment. Hepatic overexpression of LAL drove immune cell infiltration and inflammation and did not attenuate the development of NAFLD suggesting that targeting LAL expression is not a viable route to treat NAFLD.

Project description:We performed RNA-seq of livers obtained from mice fed either a control or the NASH-inducing FPC diet (Wang et al., 2016) for 24wk. In some FPC-fed mice the NASH-activated transcription factors, Elf3 or Glis2, had been deleted specifically in hepatocytes, when mice reached a steatotic state.

Project description:Resveratrol delays age-related deterioration and mimics transcriptional aspects of dietary restriction without extending lifespan A small molecule that safely mimics the ability of dietary restriction (DR) to delay age-related diseases in laboratory animals is greatly sought after. We and others have shown that resveratrol mimics effects of DR in lower organisms. In mice, we find that resveratrol induces gene expression patterns in multiple tissues that parallel those induced by DR and every-other-day feeding. Moreover, resveratrol-fed elderly mice shows a marked reduction in signs of aging including reduced albuminuria, decreased inflammation and apoptosis in the vascular endothelium, increased aortic elasticity, greater motor coordination, reduced cataract formation, and preserved bone mineral density. However, mice fed a standard diet did not live longer when treated with resveratrol beginning at mid-life. Our findings indicate that resveratrol treatment has a range of beneficial effects in mice but does not increase the longevity of ad libitum-fed animals when started mid-life. Male C57BL/6NIA mice at 11 months of age were maintained on a standard purified mouse diet (AIN-93G) for one month prior to the start of the experiment. Beginning at one year of age, SD and EOD groups were fed a standard AIN-93G diet or AIN-93G plus 0.01% or 0.04% resveratrol for the duration of the study. Three separate groups were placed on an HC diet (AIN-93G modified by the addition of hydrogenated coconut oil to provide 60% of calories from fat) or HC + 0.01% or 0.04% resveratrol 6 weeks later and remained on those diets throughout the study. SD and HC mice were fed ad libitum. EOD mice were fed ad libitum on alternate days then moved to a separate cage without food for 24 h. Food intake and body weight were measured on a weekly basis for the duration of the study.

Project description:determine the effect of the high-fat diet on the proteomics profile of liver tissue.Mice were fed with HFD for 16 weeks to establish a NAFLD mouse model. Mice fed with normal chow diet were taken as controls. Five replicate liver samples were collected from each group for proteomics analysis.

Project description:Adult male rats of the PD/Cub (PD hereafter) strains were fed a laboratory chow diet (STD, ssniff RZ, ssniff Spezialdiäten GmbH, Soest, Germany). At the age of 12 months, rats within each strain were randomly divided into two groups. The control group was fed a high-sucrose diet (HSD, sucrose 70 cal%) while the experimental group was fed a HSD fortified with quercetin (10 g/kg food, Sigma-Aldrich).

Project description:The goals of this study are to measure the microarray profiling of digoxin treated group versus vehicle control group in a 12 weeks HFD induced gene changes in liver tissue. The 'WT_LIVER" samples are from mice fed normal chow and not treated with digoxin, and the "HFD-WT" samples are from mice fed a high-fat diet and not treated with digoxin.
