New protein hormone peptides were identified by mass spectrometry of mouse serum protein under western diet state.

ABSTRACT: We have discovered a protein hormone that is induced to secrete under western diet. We used SDS-PAGE and silver staining to compare the differential bands of all proteins in the serum of mice under the chow diet state and under the western diet state, and identified several peptides of this protein under the western diet state by mass spectrometry analysis.

Western diet triggers cardiac dysfunction in heterozygous Mybpc3-targeted knock-in hypertrophic cardiomyopathy mice

Project description:The study investigates the effect of a heterozygous MYBPC3 mutation combined with Western diet feeding on protein expression in a HCM mouse model. Hypertrophic cardiomyopathy (HCM) is the most common inherited genetic heart disease, characterized by asymmetric left ventricular hypertrophy and diastolic dysfunction. It is generally accepted that HCM is caused by mutations in genes encoding sarcomere proteins (e.g. MYBPC3, MYH7). However, not all mutation carriers will develop HCM and, moreover, phenotypical variation in terms of clinical presentation is large. The phenotypical expression of HCM thus requires additional disease modifiers on top of a sarcomere gene mutation. Clinical reports identify obesity and related comorbidities (diabetes, hyperlipidemia, hypertension) as a major factor contributing to disease expression and severity. We aimed to mimic this situation in a HCM mouse model by feeding a Western diet (8 weeks) to mice carrying a heterozygous mutation in MYBPC3. These heterozygous mice are phenotype negative under normal conditions, but developed cardiac dysfunction and hypertrophy upon Western diet feeding. The main goal of this proteomic screening is to identify clusters of proteins and pathways that are down/upregulated specifically in the left ventricle of mice suffering from a mutation and Western diet feeding. Also, we are interested in protein expression differences caused solely by mutation or Western diet. Group 1 are Wild type mice that received normal chow; group 2 are heterozygous mice that received normal chow; group 3 are Wild type mice that received a Western diet; group 4 are heterozygous mice that received a Western diet.

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.

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.

Transcriptome analysis of aortic valve tissues from hyperlipidemic and control mice with normal chow diet (chow) or western diet (WD)

Project description:We performed RNA sequencing of the aortic valves of C57BL/6J (the wild type with chow diet), Ldlr-/- (1. with chow diet, 2. with WD), and Apoe-/- mice (1. with chow diet, 2. with WD) to compare the overall transcriptomic characteristics within genetic differences (wild type, Ldlr-/-, Apoe-/-) or in dietary differences (chow diet versus WD).

Proteomic analysis of the mouse tongue proteome in response to western diet

Project description:The tongue is a heavily innervated and vascularized striated muscle that plays an important role in vocalization and swallowing. The surface of the tongue is lined with papillae which contain gustatory cells expressing various taste receptors. There is growing evidence to suggest our perceptions of taste and food preference are remodelled following chronic consumption of western diets rich in carbohydrate and fats. Our sensitivity to taste and also metabolism western diets may be a key factor in the rising prevalence of obesity but a systems-wide analysis is lacking. Here, we defined the proteomic landscape of the mouse tongue and quantified changes following chronic consumption of a chow or western diet for 7 months. We observed a dramatic remodelling of the tongue proteome including changes in fatty acid and mitochondrial metabolism. The expression of several receptors, and metabolic enzymes and hormones were also differentially regulated which is exciting as these may serve as novel therapeutic targets to potentially alter taste perception and food preference to combat obesity.
