Combined metabolomic and transcriptomic profiling approaches reveal the cardiac response to high-fat diet

ABSTRACT: Purpose: Observing the response of the heart to dietary interventation at the metabolomic and transcriptomic level may have relevance for cardiovascular diseases Methods: RNA Seq of 12 week old WT male mice on chow or HFD and WT female mice on Chow or HFD; RNA was extracted and reverse-transcribed after polyA selection to complementary DNA for sequencing on an Illumina NovaSeq platform Results: RNAseq from heart tissue revealed significant differences in expression of 292 mRNA, with an FDR <0.05. PCA showed that there were significant sex differences in chow-fed mice. It also separated HFD-fed vs. Chow-fed samples for both male and female mice. Conclusions: This work reveals the response of a vital organ to dietary intervention at both metabolomic and transcriptomic levels, which is a fundamental question in physiology that may have relevance for cardiovascular diseases. This work also reveals significant sex differences in cardiac metabolites and gene expression.

High-fat diet exposure, regardless of the induction of obesity, is associated with altered expression of genes critical for normal ovarian function

Project description:High-fat diet (HFD) induces diminished ovarian reserve and subfertility in female mice, irrespective of obesity. To further assess the impact of HFD on ovarian function, female mice were fed a 60% HFD or standard chow for 10 weeks and then HFD fed mice were separated into obese (HFOB) and lean (HFLN) groups. RNA-sequencing of whole ovaries identified multiple differentially expressed genes involved in normal ovarian function (ovulation, luteinization, luteolysis) in both the HFLN and HFOB mice compared to the chow fed mice (q<0.05). Taken together, elevated dietary fat intake, regardless of obesity, is associated with impaired estrous cycles and altered expression of genes critical to normal ovulatory function.

Transcription profiling by array of adipose samples from LDLR-/- mice to study response to anti-diabetic drug and dietary lifestyle interventions

Project description:Lean male mice were fed a high fat diet (HFD, lard 24% w/w) for 16 weeks. At 9 weeks, when all hallmarks of prediabetes were established, groups of mice were treated with drug (rosiglitazone, pioglitazone, T0901317, or salicylate) for another 7 weeks together with the high fat diet. An additional group was switched back to a chow diet (dietary lifestyle intervention) after the first 9 weeks of high fat diet. All groups were compared to a control group receiving HFD alone and to a reference group fed chow (baseline reference) for the entire experimental period (16 weeks). One group (n=9) remained on maintenance chow throughout the entire study period (16 weeks) and served as healthy, age-matched control. After the nine week run-in period, the HFD fed mice were matched into thirteen groups based on body weight. The first group (n=9) was sacrificed immediately after matching. The second group (n=15) was continued on HFD until the end of the experiment at t=16 weeks. The fourth group (n=9) was switched to regular chow (dietary lifestyle intervention). The other groups (each n=9) continued on HFD supplemented with drugs typically used in clinical practice. More specifically, following drugs were mixed into HFD ; rosiglitazone (0.010% w/w), pioglitazone (0.010% w/w), T0901317 (0.010% w/w) and salicylate (0.40% w/w).

KKTa_isolated glomeruli

Project description:High dietary fat intake is a major risk factor for the development of obesity, which is frequently associated with diabetes. To identify genes involved in diabetic nephropathy, GeneChip Expression Analysis was employed to survey the glomerular gene expression profile in diabetic KK/Ta mice fed with a high-fat diet (HFD). Isolated glomeruli from three 20-week-old KK/Ta mice fed with HFD (HFD group) or a normal fat diet (Chow group) were dissected. Total RNA was extracted and labeled for hybridization using the Affymetrix GeneChip Mouse Genome 430 2.0 Array. The gene expression profile was compared between the HFD and Chow groups using GeneSpring 7.3.1 software.

Transcription profiling of hepatic response to anti-diabetic drug and dietary lifestyle interventions in LDLR-/- mice

Project description:Lean male mice were fed a high fat diet (HFD, lard 24% w/w) for 16 weeks. At 9 weeks, when all hallmarks of prediabetes were established, groups of mice were treated with drug (metformin, glibenclamide, sitagliptin, rosiglitazone, pioglitazone, fenofibrate, T0901317, atorvastatin, salicylate or rofecoxib) for another 7 weeks together with the high fat diet. An additional group was switched back to a chow diet (dietary lifestyle intervention) after the first 9 weeks of high fat diet. All groups were compared to a control group receiving HFD alone and to a reference group fed chow (baseline reference) for the entire experimental period (16 weeks).

Gene expression in chow or HFD-fed OGG1-/- livers

Project description:Gene expression in livers of male wild-type (WT) and OGG1-deficient (Ogg1-/-) mice fed either a chow diet or a high-fat diet (HFD) were examined. Mice were fed the diet for 10 weeks prior to tissue collection and were 22 weeks of age at the time of tissue collection. 24 Total samples were analyzed. We generated the following pairwise comparisons using GeneSifter: WT Chow vs Ogg1-/- Chow; WT HFD vs. Ogg1-/- HFD using t-test followed by Benjamini and Hochberg correction. An adjusted p-value less than 0.05 was considered to be statistically significant.

Spleen proteomics data from high fat diet fed mice

Project description:The composition of the diet affects many processes in the body, including body weight and endocrine system. We have previously shown that dietary fat also affects the immune system. Mice fed high fat diet rich in polyunsaturated fatty acids survive S. aureus infection to a much greater extent than mice fed high fat diet rich in saturated fatty acids. Here we present data regarding the dietary effects on protein expression in spleen from mice fed three different diets, I) low fat/chow diet (LFD, n=4), II) high fat diet rich in saturated fatty acids (HFD-S, n=4) and III) high fat diet rich in polyunsaturated fatty acids (HFD-P, n=4). We performed mass spectrophotometry based quantitative proteomics analysis of isolated spleen by implementing the isobaric tags for relative and absolute quantification (iTRAQ) approach. Mass spectrometry data were analysed using Proteome Discoverer 2.4 software using the search engine mascot against Mus musculus in SwissProt. 924 proteins are identified in all sets (n=4) for different dietary effects taken for statistical analysis using Qlucore Omics Explorer software. Only 20 proteins were found to be differentially expressed with a cut-off value of false discovery rate < 0.1 (q-value) when comparing HFD-S and HFD-P but no differentially expressed proteins were found when LFD was compared with HFD-P or HFD-S. We identified a subset of proteins that showed an inverse expression pattern between two high fat diets. These differentially expressed proteins were further classified by gene ontology for their role in biological processes and molecular functions.

Gene expression in the liver, effect of maternal high-fat diet during or prior to pregnancy

Project description:The present study aimed to examine the effect of high-fat diet prior to pregnancy on the liver of mouse offspring. Female C57BL/6J mice were fed a normal chow (15.2% fat by energy) (CTR and CTR-PP groups) or a high-fat chow (31.2% fat by energy) (HFD and HFD-PP groups) for 3−4 weeks and then mated with male C57BL/6J mice fed normal chow. Some mothers continued on the same diet until pups reached 21 days of age (CTR and HFD), and others were fed the different chows from gestational day 0 (CTR-PP and HFD-PP) to determine the effects of a high-fat diet during the pre-pregnancy period in HFD-PP/CTR and HFD/CTR-PP comparisons.
