Project description:Due to their ligand profiles, it can be hypothesized that Stab1 and Stab2 may be involved in atherosclerosis. We treated bone marrow derived macrophages (BMDM) with plasma from Stabilin-deficient and Wildtype mice to account for gene changes. We used microarrays to detail the global programme of gene expression in BMDM during different plasma treatments. We identified distinct classes of up- and down-regulated genes in response to the treatment.

Project description:LV hypertrophy is associated with Western diet consumption, while intake of n-3 polyunsaturated fatty acids is associated with anti-hypertrophic effects. We treated rats for 12 weeks with either a Control diet, a Western diet or a Western + DHA diet. For each of the 3 dietary treatments there were 2 pooled samples of heart tissue (with each pooled sample representing 5 rats) for a total of 6 arrays. Microarray analysis identified 66 differentially expressed transcripts. Pathways were identified using Ingenuity and DAVID software. Array results from two pooled samples (5 rats in each pool) for n=10 per treatment group were used for comparisons. Comparisons between Western vs. Control, Western + DHA vs. Control and Western + DHA vs. Western diets was subjected to analysis to generate log fold changes. A dietary treatment of 12 weeks was used in an effort to produce LVH while limiting the development of comorbidities. Microarray analysis was performed on pooled samples, followed by qRT-PCR and Western blot analysis. Groups were Control, Western and Western + DHA. Comparisons between groups are expressed as LogFC (i.e. LogFC_WESvCTRL, LogFC_DHAVCTRL, LogFC_DHAvWES), available in Series supplementary files.

Project description:Hepatic transcriptome of junctional adhesion molecule A knockout, F11r–/– mice fed a Western diet (WD) for eight weeks. A cohort of WD-fed mice were treated with IgG or α4β7 mAb for four weeks starting at week four following initiation of the WD.

Project description:Hepatic fibrosis is a dynamic process characterized by the net accumulation of extracellular matrix resulting from chronic liver injury such as nonalcoholic steatohepatitis. During the pathogenesis of hepatic fibrosis, activation of hepatic stellate cells (HSCs) causes transdifferentiation of quiescent cells into proliferative and fibrogenic myofibroblasts. In the present study, we developed a novel RORα-selective ligand, ODH-08, based on the modification of JC1-40, a previously reported N-methylthiourea analog. Administration of ODH-08 to Western diet (WD)-fed mice improved the signs of hepatic fibrosis: decreased hepatic collagen deposition and suppression of the expression of fibrogenic markers. ODH-08 inhibits the TGF1-induced fibrogenic activation of HSCs through suppression of the TGFβ1–SMAD signaling pathway, which represents a novel mechanism for the antifibrogenic effect of RORα. Thus, ODH-08 appears to be a promising antifibrotic agent to treat hepatic fibrosis. We performed a microarray analysis in the liver tissue of ODH-08-treated WD-fed mice to anlyse differentially expressed genes under ODH-08 administration. The control group was vehicle-treated WD-fed mice.

Project description:SHP (small heterodimer partner; NR0B2) belongs to the nuclear hormone receptor superfamily, which regulates numerous developmental and metabolic cellular functions. To study physiological function of SHP, we generated congenic SHP-/- mice on C57Bl/6 background. When the congenic SHP-/- mice were challenged with a western diet (harlan, TD.88137) for 22 weeks, they were resistant to diet induced obesity and hepatic steatosis compared to WT controls. However, their hepatic insulin sensitivity was compromised when assessed with phospho-Akt levels after insulin injection. Therefore, we investigated hepatic gene expression using illumina beadchip array to explore mechanisms underneath the unique liver physiology in SHP-/- mice. Livers were collected from C57Bl/6 wild type and C57Bl/6 SHP-/- mice fed chow or western diet. The 1 microgram of total RNA obtained from individual mouse (n=4 per group) and subjected to illumina beadchip gene expression profiling.

Project description:Resistant starches (RS), fed as high amylose maize starch (HAMS) or butyrylated HAMS (HAMSB), oppose dietary protein-induced colonocyte DNA damage in rats. In this study, rats were fed diets high in fat (19%) and protein (20%) with different forms of digestible starch (low amylose maize starch (LAMS) or low amylose whole wheat (LAW)) or RS (HAMS, HAMSB, or a whole high amylose wheat (HAW) generated by RNA interference (RNAi)) for 11 wk. A control diet contained 7% fat, 13% protein and LAMS. The aim of this study was to detect changes in the expression of DNA damage and repair genes in response to the above dietary treatments.

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.
