High fat diet inhibits EV-Mediated angiogenisis

ABSTRACT: Mesenchymal stem cell-derived extracellular vesicles (EVs) have been shown to promote angiogenesis in the ischemic myocardium. This study examines the difference in vascular density, myocardial perfusion, molecular signaling, and gene expression between normal diet (ND) and high fat diet (HFD) groups at baseline and following intra-myocardial injection of EVs We used GeneChip Gene Arrays for whole-transcriptome analysis between normal diet and high fat diet groups at baseline and following intra-myocardial injection of Evs.

Fat BodFat Body, Hungry Brain: Nutriproteomics in the Hypothalamus from a Mouse Model with Obesity and Anorexiay, Hungry Brain: Nutriproteomics in the Hypothalamus from a Mouse Model with Obesity and Anorexia

Project description:Systemic acute inflammatory signals can cause profound anorexia by disrupting the physiological appetite regulation in the hypothalamic milieu. Conversely, obesity related chronic inflammation of the hypothalamus can disturb anorexigenic signals and promote abnormal body weight control. The aim of the present study was to compare the global hypothalamic endophenotype in C57/Bl6 mice exposed to a high-fat diet or with acute illness mediated by LPS. Ten-week old male C57/Bl6 mice (n=18) were randomly divided into four groups; the control 1 group (n =3) was fed a normal diet whereas the high-fat diet (HFD) group (n =6) was fed a high-fat diet for eight weeks. The control 2 group (n=3) received an intraperitoneal injection of saline whereas the LPS group (n=6) received an intraperitoneal injection of LPS. Mice were sacrificed 18-hr post-injection. Both control 2 and LPS groups were fed a normal diet for eight weeks before the injection. The hypothalamic regions were removed and analysed using a 2D LC-MS methodology. The proteomic analysis profiled 9,235 proteins (q<0.05) across all biological states, of which 522 proteins were found modulated in the HFD group and another 579 in the LPS group. The proteomic profiles demonstrated that the systemic acute inflammation linked with anorexia induced a negative feedback loop of appetite control in the hypothalamus, suggesting an effort to re-establish homeostasis. By contrast, the chronic inflammation associated with obesity initiated a “perpetual cycle” of positive feedback enhancement of appetite regulation further exacerbating positive energy balance.

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).

RNA-seq of gastrocnemius (GA) muscle tissue from mice treated with extracellular vesicles (EV) from MCF-10A /miR122 cells

Project description:To detect gene expression changes in skeletal muscle caused by EVs from mMCF-10A/miR-122 cells, we analyzed RNA isolated from the GA muscle of EV-treated female NOD scid gamma (NSG) mice. Mice had received tail-vein injections of EVs twice a week for 5 weeks (~10 ug EV per injection). Gene expression in muscle from mice treated with MCF-10A/miR-122-derived EVs.

Differentially enriched miRNAs in EVs derived from young and aged osteocytes of mice

Project description:Vascular calcification often occurs with osteoporosis, a contradictory association called “calcification paradox”. We find that extracellular vesicles (EVs) released from aged bone matrix (AB-EVs) during bone resorption favor adipogenesis rather than osteogenesis of BMSCs and augment calcification of vascular smooth muscle cells (VSMCs). Intravenous or intramedullary injection of AB-EVs promotes bone-fat imbalance and exacerbates Vitamin D3 (VD3)-induced vascular calcification in young or old mice. To explore the involvement of miRNAs in the AB-EVs-induced promotion of adipocyte formation and vascular calcification, the Agilent miRNA array was conducted to compare the miRNA expression profiles in AB-EVs and YB-EVs from mouse bone specimens. Our study uncovers the role of AB-EVs as a messenger for calcification paradox by transferring functional miRNAs.

RNA-seq of gastrocnemius (GA) muscle tissue from mice treated with extracellular vesicles (EV) from MCF-10A or MDA-MB-231 cells

Project description:To compare gene expression changes in skeletal muscle caused by EVs from normal (MCF-10A) and cancer (MDA-MB-231) cells, we analyzed RNA isolated from the GA muscle of EV-treated female NOD scid gamma (NSG) mice. Mice had received tail-vein injections of EVs twice a week for 5 weeks (~10 ug EV per injection). Gene expression in muscle from mice treated with MDA-MB-231-derived EVs was compared to mice treated with MCF-10A-derived EVs.

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).

Gene expression changes in human peripheral blood mononuclear cells after 3 diet interventions, TMD enriched with olive oil, TMD enriched with nuts and Low fat diet.

Project description:Despite the benefits associated with healthy diets, data on the mechanisms by which these benefits are promoted are scarce. Our aim was to explore the global transcriptomic response of biological pathways related to cardiovascular disease associated with traditional Mediterranean diet (TMD) intervention. The PREDIMED study is a large on-going, parallel, multicentre, randomised, controlled trial aimed at assessing the TMD effect on primary cardiovascular prevention. High cardiovascular risk participants were recruited and assigned to one of the following interventions: 1) TMD plus virgin olive oil (VOO); 2) TMD plus mixed nuts; or 3) low-fat diet (control group). In a sub sample of 30 volunteers of the PREDIMED- Barcelona Sur Centre, gene expression changes in peripheral mononuclear cells, after 3 months of intervention, were assessed by microarray analysis. A parallel study comparing three diet interventions: We analyzed 65 arrays which belonged to 34 patients, 31 microarrays at baseline (11 baseline group 1; 11 baseline group 2; 9 baseline group 3) and 34 microarrays after the 3 month intervention (11 for group 1; 11 for group 2; and 12 for group 3). The three interventions were: Group 1: 3-month Traditional Mediterranean Diet enriched with virgin olive oil; Group 2: 3-month Traditional Mediterranean Diet enriched with nuts; and Group 3: 3-month Low Fat Diet.
