Project description:Previous studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. We used microarrays to compare MTHFR+/+ BALB/c mice fed control diet and MTHFR+/- BALB/c mice fed low folate diet.

Project description:Previous studies in our laboratory have shown that low folate diet (control diet with 2mg folate/kg, low folate diet with 0.3mg folate/kg) can induce intestinal tumors in BALB/c mice. We used microarrays to compare MTHFR+/+ BALB/c mice fed control diet and MTHFR+/- BALB/c mice fed low folate diet. After weaning, 4 BALB/c Mthfr +/+ mice were fed with a control diet (CD, 2mg folate/kg) and 4 BALB/c Mthfr +/- mice were fed a low folate diet (FD, 0.3mg folate/kg) for 1 year. Both diets contain succinylsulfanthiozole (1%) to prevent folate synthesis by intestine microbial biota.

Project description:Perfluorooctanesulfonic acid (PFOS) is a persistent, bio-accumulative pollutant that has been used for the last 60+ years in numerous industrial and commercial applications. In mice, PFOS administration is known to induce hepatomegaly and hepatic steatosis. The aim of the present study was to evaluate potential PFOS and diet interactions and explore the mechanism of PFOS induced liver lipid accumulation. Prior to PFOS administration, mice were fed either a standard chow diet (SD) or 60% kCal high fat diet (HFD) for 4 weeks to establish significant body weight increase. After 4 weeks of diet acclimation, the treatment groups received 0.0003% PFOS in diet for an additional 10 weeks. In addition, a subset of the mice fed HFD were switched to a SD (H-SD) to mimic weight-loss induced improvement of hepatic steatosis. A total of six treatment groups: i) SD, ii) HSD, iii) HFD (H), iv) SD +PFOS(SDP), v) H-SD +PFOS (HSDP), and vi) HFD +PFOS (HP) were included. PFOS and lipid concentrations were measured in both serum and liver. Relative liver mRNA expression was determined by targeted bead array and proteins were quantified using untargeted mass spectrometry. PFOS exposure increased liver weight, and in the HFD increased liver triglycerides and liver cholesterol content. Gene and protein expression in the liver demonstrated that PFOS exposure induced lipid utilization and xenobiotic metabolism pathways, and in a HFD, induced lipid synthesis. The data suggests that PFOS exposure acts on lipid utilization genes and exacerbates hepatic steatosis in mice fed a HFD.

Project description:We showed that diets containing 0.1% or 0.5% quercetin lowered the STZ-induced increase in blood glucose levels and improved plasma insulin levels. A cluster analysis of the hepatic gene expressions showed that 0.5% quercetin diet suppressed STZ-induced alteration of gene expression. Gene set enrichment analysis (GSEA) and quantitative RT-PCR analysis showed that the quercetin diets had their greatest suppressive effect on the STZ-induced elevation of expression of cyclin dependent kinase inhibitor p21(WAF1/Cip1) (Cdkn1a). In this experiment, we determined the effect of quercetin on healthy control BALB/c mice that were fed the AIN93G diet containing 0, 0.1, 0.5 or 1% quercetin for 2 weeks. GSEA and one-way ANOVA did not detect any significant changes in hepatic gene expression in normal mice as a result of a quercetin diet. Using a linear modeling approach and the empirical Bayes statistics, we found that Ubc were significantly reduced by both the 0.5% and 1% quercetin. Six-week-old male mice were divided into 4 groups of 6 mice each, housed in groups of 3 per cage, and fed a standard purified AIN-93G diet containing 0% (Control), 0.1% (0.1), 0.5% (0.5), or 1% quercertin (1.0) for 2 weeks.

Project description:In this study we sought to determine how hepatocyte-specific PPARgamma expression regulates hepatic gene expression in normal (healthy) mice fed a LFCF diet, or mice that were fed a HFCF diet for 24 weeks to induce non-alcoholic steatohepatitis (NASH). Specifically, we used chow-fed adult (10 week-old) PPARgamma floxed male mice and injected them with AAV8-TBG-Cre to knockout PPARgamma in hepatocytes (KO). A subset of PPARgamma floxed mice were injected with AAV8-TBG-Null to generate controls (C). Two weeks after AAV injections, half of the mice in each group were fed a low fat, cholesterol and fructose (LFCF) diet, or a high fat, cholesterol and fructose (HFCF) diet for 24 weeks. Livers were collected at the end of the study to assess hepatic gene expression with RNA-seq (performed by Novogen, Inc.)

Project description:The effect of high fat diet feeding on liver gene transcription regulation was investigated in BALB/c mice using Affymetrix gene expression arrays. Expression data was determined in 5 months old male mice fed a high fat diet (40% fat) for 15 weeks. Control mice were fed a standard carbohydrate chow. Six animals per group were used.

Project description:Quercetin is a food component that may ameliorate the diabetic symptoms. We examined hepatic gene expression of BALB/c mice with streptozotocin (STZ)-induced diabetes to elucidate the mechanism of the protective effect of dietary quercetin on diabetes-associated liver injury. We fed STZ-induced diabetic mice with diets containing 0.1% or 0.5% quercetin for 2 weeks and compared the patterns of hepatic gene expression in these groups of mice using a DNA microarray. Diets containing 0.1% or 0.5% quercetin lowered the STZ-induced increase in blood glucose levels and improved plasma insulin levels. A cluster analysis of the hepatic gene expressions showed that 0.5% quercetin diet suppressed STZ-induced alteration of gene expression. Gene set enrichment analysis (GSEA) and quantitative RT-PCR analysis showed that the quercetin diets had their greatest suppressive effect on the STZ-induced elevation of expression of cyclin dependent kinase inhibitor p21(WAF1/Cip1) (Cdkn1a).

Project description:De novo lipogenesis (DNL) has been implicated in the development and progression of hepatic liver steatosis. Hepatic DNL is strongly influenced by dietary macronutrient composition with diets high in carbohydrate increasing DNL and diets high in fat decreasing DNL. The enzymes in the core DNL pathway have been well characterised however less is known about proteins that play accessory or regulatory roles in DNL. In the current study, we associate measured rates of hepatic DNL and liver fat content with abundance of liver proteins from liquid chromatography mass spectrometry in mice to identify known and uncharacterised proteins that may have a role in DNL. Male C57BL/6J mice were fed either a standard chow diet a semi-purified high starch diet or a high fat diet. Both semi-purified diets resulted in increased body weight, fat mass and liver triglyceride content compared to chow-fed mice while hepatic DNL was increased in the high starch fed mice and decreased in the high fat fed mice. Proteomic analysis was carried out on the livers of these mice and proteins were identified that associated with either the rate of DNL or triglyceride content in the liver. There was no overlap between DNL and triglyceride associated proteins. We identify novel proteins associated with DNL that are involved in taurine metabolism, which suggests a link between these pathways. Further analysis identified proteins that are differentially regulated when comparing a non-purified chow diet to either of the semi-purified diets to provide a set of proteins that are regulated by the degree of dietary complexity alone. Finally, we compared the liver proteome between 4 week-fed and 30-week diet-fed mice and found remarkable similarity suggesting that the majority of diet-regulated proteins change early in response to differing dietary components.
