Project description:The impact of high fat diet on secreted milk small RNA transcriptome was studied by isolating total RNA from milk fat fraction collected on lactation day 10 from control diet fed (C; n=5; 10% fat; 7% sucrose; Research Diets #D12450J, Brunswick, NJ) and high fat diet fed (HF; n=4; Research Diets #D12492, 60% of total kcal energy is fat and match 7% of total kcal is sucrose; Brunswick, NJ) mice.

Project description:Most commonly used models of non-alcoholic steatohepatitis (NASH) are diets based on specific gene knockouts or represent extreme manipulations of diet. We have examined the effects of modest increased caloric intake and high dietary unsaturated fat content on the development of NASH in male rats using a model in which overfeeding is accomplished via intragastric infusion of liquid diets as a part of total enteral nutrition. Male Sprague dawley rats were fed diets 5% corn oil containing diets at 187 Kcal/kg3/4/d or fed 70% corn oil containing diets at 220 Kcal/kg3/4/d for a period of 3 weeks. Hepatic gene expression were assessed at the end of the study. Our results indicate that overfeeding of high unsaturated fat diets leads to pathological, endocrine and metabolic changes characteristic of NASH patients and is associated with increased oxidative stress and TNF-a. Experiment Overall Design: Two groups of male sprague dawley rats were fed liquid diets via total enteral nutrition. Experiment Overall Design: Group 1, Control, Rats were fed diets containing 5% Corn oil at 187 Kcal/kg3/4/d for 3 weeks. Experiment Overall Design: Group 2, NASH, Rats were fed diets containing 70% corn oil at 220 Kcal/kg3/4/d for 3 weeks.

Project description:The present study was conducted to evaluate the effects of the intake of three types of coffee (caffeinated, decaffeinated, and green unroasted coffee) on the livers of C57BL/6J mice fed a high-fat diet, and to extensively elucidate the physiological responses to coffee intake by analysing the findings obtained from a comprehensive transcriptomic analysis using DNA microarrays. The present study was conducted to evaluate the effects of the intake of three types of coffee (caffeinated, decaffeinated, and green unroasted coffee) on the livers of C57BL/6J mice fed a high-fat diet, and to extensively elucidate the physiological responses to coffee intake by analysing the findings obtained from a comprehensive transcriptomic analysis using DNA microarrays. Briefly, 7-week-old male C57BL/6J mice purchased from Charles River Laboratories Japan (Yokohama) were divided into the following five groups. The normal diet group (ND group) was fed D12450B (10 kcal% fat, Research Diets, New Brunswick, NJ, USA). The high-fat diet group (HF group) was fed D12492 (60 kcal% fat, Research Diets, New Brunswick, NJ, USA). The caffeinated coffee group (HFCC group) was fed a high-fat diet containing 2% caffeinated freeze-dried coffee. The decaffeinated coffee group (HFDC group) was fed a high-fat diet containing 2% decaffeinated freeze-dried coffee. The green unroasted coffee group (HFGC group) was fed a high-fat diet containing 2% unroasted caffeinated freeze-dried coffee. The mice had ad libitum access to their diets and drinking water. After 9 weeks, mice were sacrificed and the livers were subjected to the Affymrtix DNA microarray experiment.

Project description:Purpose: To investigate the effects of weight cycling on the metabolic homeostasis Methods: C57BL/6 mice were fed with high fat diet (HF) (60% kcal fat; Research Diets Inc., New Brunswick, NJ) or low fat diet (LF) (10% kcal fat; Research Diets Inc.) at 6-week-old. Nine weeks after in HF, a part of mice was switched to LF for one week followed by one week HF as one cycle, and the mice under this one week diet switch protocol for 10 cycles were named HF-LF cycled mice, while the left part of mice under continuously HF-feeding were named HF mice. The mice kept in the continuously LF-feeding were named LF mice Results: We identified many changed genes in the eWAT by RNA-sequencing. Conclusions: This finding provides a signaling in eWAT upon weight cycling

Project description:To investigate the role of hepatic Pck1 in diet-induced nonalcoholic steatohepatitis (NASH), liver-specific Pck1-knockout mice were developed with Alb-Cre. Wild-type (WT) and Pck1-cKO mice were fed a Chow diet (Research Diets, D12450J: 10% Kcal fat, with tap water) or NASH-inducing diet (Research Diets, D12492: 60% Kcal fat, with drinking water containig 23.1 g/L fructose and 18.9 g/L glucose) for 24 weeks. RNA was extracted from the livers of mice from all treatment groups and used for RNA seqencing. RNA-seq data demonstrated that gluconeogenic enzyme PCK1 deficiency played an important role in the development of NASH.

Project description:High fat diets (HFDs) are linked to several diseases including obesity, diabetes, insulin resistance, fatty liver, and susceptibility to inflammatory bowel disease (IBD) in both mouse and humans. RNA-seq from male mice (C57BL/6N) fed Vivarium Chow (VIV) or any one of three high fat diets (40% kcal fat) (SO+CO, PL+CO, CO) for 24 weeks was performed on four segments of the intestinal tract (Duodenum, Jejunum, Terminal Ileum and Proximal Colon).

Project description:Obesity was induced by ad libitum feeding of C57/BL6 mice for 12 week with irradiated high fat diet (Rodent Diet 60% kcal from fat, Research Diets, Inc., Cat #D12492). Control diet (chow) containing 24% protein, 47.5% carbohydrate, and 4.9% fat, was given to age and sex matched animals as a control group.

Project description:Male C57BL/6J mice were fed a high-fat diet (HFD, 60 kcal% fat, D12492, Research Diets, Inc) or normal standard chow diet with 10 kal% fat (ND, D09100304, Research Diets, Inc). Specifically, 6-week-old mice were fed a HFD for 12 weeks to induce insulin resistance (HFD-12w group); 14-week-old mice were fed a HFD for 4 weeks to induce obesity (HFD-4w group). Control mice were fed a ND continuously for 12 weeks starting at 6 weeks of age (ND group). All mice reached the experimental endpoint at 18 weeks of age. Insulin sensitivity was measured by glucose tolerance test and insulin tolerance test. Mice that developed insulin resistance in HFD-12w group and obese mice with normal insulin sensitivity in HFD-4w group were used for further experiments. Mice in ND group were used as controls. Upon reaching the experimental endpoint, livers from three insulin-resistant mice, three insulin-sensitive obese mice, and three control mice were removed for RNA sequencing.
