Project description:The aim of this study was to elucidate the impact of ATP7B deficiency on hepatic gene expression profiles in mice fed a high-fat diet. Systemic ATP7B-knockout (Atp7b-/-) mice on a C57BL/6J genetic background were generated via CRISPR/Cas9 technology and subjected to a high-fat, high-fructose, and high-cholesterol diet (abbreviated as high-fat diet, HFD) for 24 weeks to establish a steatohepatitis model. Hepatic gene-expression profiles were analyzed by RNA sequencing (RNA-seq). ATP7B deficiency exacerbated hepatic inflammation and fibrosis in HFD-fed mice, as revealed by RNA-seq data.

Project description:Inactivating mutations in the copper transporter Atp7b result in Wilson’s disease. The Atp7b-/- mouse develops hallmarks of Wilson’s disease. The activity of several nuclear receptors is decreased in Atp7b-/- mice, and nuclear receptors are critical for maintaining metabolic homeostasis. Therefore, we anticipated that Atp7b-/- mice would exhibit altered progression of diet-induced obesity, fatty liver, and insulin resistance. Following 10 weeks on a chow or Western-type diet (40% kcal fat), parameters of glucose and lipid homeostasis were measured. Hepatic metabolites were measured by LC-MS and correlated with transcriptomic data. Atp7b-/- mice fed a chow diet had lower fat mass and were more glucose tolerant than wild type (WT) littermate controls although body weights did not differ between genotypes. On Western diet, Atp7b-/- mice exhibited reduced adiposity and hepatic steatosis compared with WT controls. Atp7b-/- mice fed either diet were more insulin sensitive than WT controls; however, fasted Atp7b-/- mice exhibited hypoglycemia after administration of insulin, due to an impaired glucose counter-regulatory response, as evidenced by reduced hepatic glucose production. Coupling gene expression with metabolomic analyses, we observed striking changes in hepatic metabolic profiles in Atp7b-/- mice. In addition, the active phosphorylated form of AMP kinase was significantly increased in Atp7b-/- mice relative with WT controls. Alterations in hepatic metabolic profiles and nuclear receptor signaling were associated with improved glucose tolerance and insulin sensitivity, as well as impaired fasting glucose production in Atp7b-/- mice.

Project description:The objective of the experiment was to dissect the effects of a high-fat diet on juvenile adipose tissue gene expression under conditions of excess calorie intake versus normal calorie intake in comparison to a standard low-fat diet. For this purpose juvenile mice were fed (A) a standard low-fat diet (CD), (B) a high-fat diet ad libitum (excess calorie intake) (HFD) and (C) a high-fat diet with calorie consumption restricted to the calorie consumption of the CD diet (R-HFD). RNA expression was profiled after 1 week of feeding in the periuterine fat depot.

Project description:We investigated remodeling of the mitochondrial proteome to determine mechanisms of changes to lipid oxidation following high-fat feeding. C57BL/6J mice consumed either a high-fat diet (HFD, 60% fat) or low fat diet (LFD, 10% fat) for 12 weeks. Mice were fasted 4 hours then anaesthetized by sodium pentobarbital for tissue collection. A mitochondrial-enriched fraction was prepared from gastrocnemius muscles and underwent proteomic analysis by high-resolution mass spectrometry.

Project description:Younger age and obesity increase the incidence and rates of metastasis of triple-negative breast cancer (TNBC), an aggressive subtype of breast cancer. The tissue microenvironment, specifically the extracellular matrix (ECM), is known to promote tumor invasion and metastasis. We sought to characterize the effect of both age and obesity on the ECM of mammary fat pads. We used a diet-induced obesity (DIO) model where 10-week-old female mice were fed a high-fat diet (HFD) for 16 weeks or a control chow diet (CD) where time points were every 4 weeks to monitor age and obesity HFD progression. We isolated the mammary fat pads to characterize the ECM at each time point. Utilizing proteomics, we found that the early stages of obesity were sufficient to induce distinct differences in the ECM composition of mammary fat pads that promote TNBC cell invasion. ECM proteins previously implicated in driving TNBC invasion Collagen IV and Collagen VI, were enriched with weight gain. Together these data implicate ECM changes in the primary tumor microenvironment as mechanisms by which age and obesity contribute to breast cancer progression.

Project description:Males and females from each SM/J and LG/J were placed on either a low-fat diet or high-fat diet immediately after weaning until 20 weeks of age. At 20 weeks, mice were sacrificed in late morning after a four-hour fast and liver tissue was collected from 4 males and 4 females from each strain and diet.

Project description:Gene transcription in epididymal fat pads was investigated in an F2 cross of 129S6 x Balb/c mice using Illumina gene expression arrays. Expression data was determined in 5 months old male mice fed a high fat diet (40% fat) for 15 weeks.

Project description:In the present study, we designed a 7-week rat model, consuming high-fat diet or heat-misture-treated high fat diet. The liver was used for microarray analyses. Transcriptome profiling reveal that high-fat diet with or with out heat-moisture treatment induced different transcriptome changes, mainly on lipid metabolism and inflammation.
