Project description:We used microarrays to study the gene expression dynamics during caloric restricted weight loss in obese mice after feeded with high fat diet. C57BL/6J male mice were placed on a high fat diet at 10-11 weeks of age in individual cages and kept on the diet until they reached ~ 41 g. After all the baseline (41g) measurement were made, each mouse was fed 75% of their ad libitum food intake in two divided daily "meals". The high fat diet was maintained. Mice were sacrificed after 0, 1, 3, 7, 14, 21 or 42 day of caloric restriction. Hypothalamus, liver, abdominal subcutaneous adipose, mesenteric adipose, perirenal adipose and perigonadal adipose tissues were collected for RNA extraction and hybridization on Affymetrix microarrays.

Project description:We recruited ten normal-weight healthy men using inclusion criteria as previously described (Collet et al 2017). All males were healthy and not obese or overweight (average age: 23.8 years, average BMI (kg/m2): 23.3). Participants at baseline consumed a balanced diet (50% carbohydrate, 30% fat, and 20% protein). During caloric restriction, volunteers consumed 10% of normal energy requirement (226 kcal/d) for two days, again balanced (50% carbohydrate, 30% fat, and 20% protein), with the same macronutrient composition. After caloric restriction, volunteers were offered three substantial ad libitum buffet meals per day (20 MJ = 4,777 kcal) and additional snacks (16 MJ = 3,821 kcal) between meals for 2 days. They were invited to eat freely until comfortably full; food consumption was covertly measured. We collected fasting plasma samples at 0800 AM at baseline, after CR and refeeding (RF).

Project description:Roux-en-Y gastric bypass (RYGB) is the most effective therapy for morbid obesity, but it has a ~20% failure rate. We used our established RYGB model in diet-induced obese (DIO) Sprague-Dawley rats, which reproduces human bi-phasic body weight (BW) loss pattern, to determine mechanisms contributing to success (RGYB-S) or failed (RYGB-F) RYGB. DIO rats were randomized to RYGB, sham operated Obese, and sham operated obese pair fed-linked to RYGB (PF) groups. BW, caloric intake (CI) and fecal output (FO) were recorded daily for 90 days, food efficiency (FE) was calculated, and morphologic changes were determined. Gut, adipose and thyroid hormones were measured in plasma. Mitochondrial respiratory complexes in skeletal muscle, expression of energy-related hypothalamic and fat peptides, receptors and enzymes were quantified. A 25% failure rate occurred. RYGB-S, RYGB-F and PF rats vs. Obese showed rapid BW decrease, followed by sustained BW loss in RYGB-S. RYGB-F and PF gradually increased BW. Expression profiling of both CNS (hypothalamus) and peripheral tissues (subcutaneous abdominal fat) strongly supported the involvement of a number of metabolic and feeding-related genes in the differential outcomes. Experiment Overall Design: 3 biological replicate RNA samples were prepared from 2 tissues (the subcutaneous abdominal fat or the hypothalamus) from rats in 3 treatment groups (rats losing weight successfully after gastric bypass surgery, rats gaining weight, and rats that were fed the same amount as the treated rats)

Project description:High caloric regimen affects brain functions leading to metabolic dysfunction and obesity and represents a risk factor for mental illness and dementia. To better understand the mechanisms underlying this process, we evaluated the effects of a prolonged exposure to high fat diet on cerebral glucose metabolism, inflammation, neuronal plasticity and transcriptome changes. We used Clariom S microarrays on GeneChip® Scanner 3000 7G to detect gene expression changes during high fat diet regimen inducing metabolic syndrome in young/adult male and female wt mice in anterior cortex and cerebellar region

Project description:To profile the expression of circulating miRNAs in a mouse model of diet-induced obesity (DIO) with subsequent weight-reduction with low-fat diet (LFD), eighteen C57BL/6 male mice were grouped into three subgroups as: (1) Control: the mice fed with the standard AIN-76A (fat: 11.5 kcal%) diet for 12 wks; (2) DIO: the mice fed with 58 kcal% high-fat diet for 12 wks; (3) DIO+LFD: the mice fed with high-fat diet for 8 wks to induce obesity, then changed to 10.5 kcal% low-fat diet for subsequent 4 wks. C57BL/6 mice were purchased from BioLasco (Taipei, Taiwan). All housing conditions were maintained, and surgical procedures, including analgesia, were performed in an Association for Assessment and Accreditation of Laboratory Animal Care International (AAALAC)-accredited SPF facility according to national and institutional guidelines. In this experiment, eighteen C57BL/6 wild type male mice were randomly grouped into three subgroups (n=6 in each group): (1) Control: the control mice were fed ad libitum a standard AIN-76A (fat: 11.5 kcal%) diet for 12 wks; (2) DIO: the mice were fed ad libitum a 58 kcal% HFD (D12331; Research Diets Inc., New Brunswick, NJ) for 12 wks to induce obesity; (3) DIO+LFD: the mice fed ad libitum a 58 kcal% HFD (D12331) for 8 wks to induce obesity, then continued the feeding of 10.5 kcal% LFD (D 12329; Research Diets Inc.) for additional 4 wks. Weight measurements were performed on a weekly basis to for these three groups of mice. Evaluation of blood glucose levels was performed at the beginning and in the end of the experiment to confirm that the HFD-fed mice developed an obese and insulin resistant phenotype. After the end of experiment at 12w, all mice were killed. The abdominal WAT of each mice was removed and weighted. Paraffin-embedded abdominal WAT was sectioned at 5 M-NM-<m and stained with hematoxylin and eosin to measure mean adipocyte area. A volume of 1 mL of whole blood was collected into a plain tube and allowed to clot for 1 hour. The sera samples were aliquoted after centrifugation at 3,000 M-CM-^W g for 10 minutes and stored at M-bM-^HM-^R80M-BM-0C until further analysis.

Project description:Atherosclerosis is a progressive disease characterized by the accumulation of lipids in the large and medium sized arteries. Lipoproteins and the endothelium play critical roles in the onset of atherosclerosis through the regulation of trans-endothelial lipoprotein flux in the subintima, the expression of adhesion molecules and proinflamatory cytokine, and the recruitment of monocytic precursors to intimal macrophage foam cells. Although it has been greatly studied in animal models, including rabbits, pigs, non-human primates and rodents, the early development of atherosclerosis is unknown. In this study, we characterized the temporal changes of carotid endothelial transcriptome in hyperlipidemic pigs using next-generation RNA sequencing. Twenty litters of castrated barrows swine (Yorkshire x Landrace) were raised on a normal diet. The swine (~250 lbs) were then fed with a diet high in fat and cholesterol (HFHC) for 0, 2, 4, 8, or 12 weeks (n=4 animals for each time point) prior to tissue collections. The normal diet consisted of a standard commercial corn/soybean meal diet (18% crude protein) at 100% ad libitum intake. The isocaloric high fat/high cholesterol diet consisted of 16.5% crude protein, 15% fat and 1.5% cholesterol at 80% of the ad libitum feed rate (by weight) such that the caloric intake/kg BW were approximately the same as the control diet. Diets were adjusted biweekly according to body weight. Food was withheld for 24 hours prior to endothelium collection in order to permits the collection of blood for fasting lipid levels.

Project description:To assess the transcriptional changes in different brain regions and spinal cord associated with aging and either a caloric restricted (CR) or ad libitum (AL) diet. cDNA microarray and quantitative PCR analyses were used to examine the transcriptomes of various neuronal tissues in young, middle aged and old mice. Mice of both genders were examined as well as the effects of their placement on either caloric restricted (CR) or ad libitum (AL) diets.
