Changes in hepatic transcriptome profile in α4β7 mAb-treated Western diet-fed mice

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.

Hepatic Lysosomal Acid Lipase Overexpression Worsens Hepatic Inflammation in Mice Fed a Western Diet

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.

Hepatic gene expression in wild type and SHPKO mice fed chow or western diet

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.

Expression data from Control diet, Western diet and Western diet + DHA fed rats.

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.

Renal Proximal Tubule Cell-specific Megalin Deletion Induces Tubulointerstitial Nephritis in Mice Fed Western Diet

Project description:Pharmacological inhibition of megalin (also known as low-density lipoprotein receptor-related protein 2: LRP2) attenuates atherosclerosis in hypercholesterolemic mice. Since megalin is abundant in renal proximal tubule cells (PTCs), PTC-LRP2 +/+ and -/- littermates in an LDL receptor -/- background were generated and fed a Western diet to determine effects of PTC-derived megalin on atherosclerosis. PTC-specific megalin deletion did not attenuate atherosclerosis in LDL receptor -/- mice in either sex. Serendipitously, we discovered that PTC-specific megalin deletion led to interstitial infiltration of CD68+ cells and tubular atrophy. The pathology was only evident in male PTC-LRP2 -/- mice fed the Western diet, but not in mice fed a normal laboratory diet. Renal pathologies were also observed in male PTC-LRP2 -/- mice in an LDL receptor +/+ background fed the same Western diet, demonstrating that the renal pathologies were dependent on diet and not hypercholesterolemia. By contrast, female PTC-LRP2 -/- mice had no apparent renal pathologies. In vivo multiphoton microscopy demonstrated that PTC-specific megalin deletion dramatically diminished albumin accumulation in PTCs within 10 days of Western diet feeding. RNA sequencing analyses demonstrated the upregulation of inflammation-related pathways in kidney. Overall, PTC-specific megalin deletion leads to tubulointerstitial nephritis in mice fed Western diet, with severe pathologies in male mice.

Effect of depletion of TAS1R3 on testicular gene expression in mice fed long-term western diet

Project description:Recent studies suggest that the western diet negatively affects male reproduction, but few underlying molecular mechanisms have been established. Also, several studies have reported TAS1R3 is expressed in testis, epididymis and sperm, but their role in male reproduction remains unknown. To investigate the function of taste receptor TAS1R3 in the male reproductive function under western diet condition, we performed RNA-sequencing analysis on testes from C57BL/6 mice fed long-term (18 weeks) western diet.

transcription profiling by array of C57BL/6J mice fed a Western-style diet with or without 0.05% quercetin against mice on a control diet to study the effect of quercetin on obesity and hepatic gene expression

Project description:To determine the effect of consumption of a quercetin-rich diet on obesity and dysregulated hepatic gene expression, C56BL/6J mice were fed for 20 weeks on control or a Western diet high in fat, cholesterol and sucrose, both with or without 0.05% quercetin. Chronic dietary intake of quercetin reduced body weight gain and visceral and liver fat accumulation, and improved hyperglyceamia, hyperinsulinaemia, dyslipidaemia in mice fed a Western-style diet. Feeding a Western-style diet altered expression of genes related to inflammatory responses, lipid metabolism and oxidative phosphorylation in C57BL/6J mice after 20 weeks. The results from exhaustive gene expression analysis showed that quercetin minimally influenced hepatic gene expression in mice fed the Western diet. The gene screening results (GSEA) were consistent with the notion that it did improve mitochondrial function to some extent. Quantitative RT-PCR analysis indicated that quercetin did influence important regulators of fat accumulation and metabolic disorders. Our results suggest that quercetin reduces fat accumulation presumably through decreasing oxidative stress and increasing PPARα expression, and the following improvement of gene expression related to steatosis in the liver. C56BL/6J mice were fed for 20 weeks on AIN93G (con) or a Western diet high in fat, cholesterol and sucrose, both with or without 0.05% quercetin for 20 weeks.
