Introduction

Considering that a spontaneous caloric increase is difficult to achieve in rodents, even when flavored diets are offered [ 6 ], DIO must have a high caloric density [ 1630 ]. Inhibitory effects of DoenjangKorean traditional fermented soybean paste, and oxidative stress and inflammation in adipose tissue of mice fed a high-fat diet. Cafeteria diet increased adiposity in comparison to high fat diet in young male rats. Different times of intervention, diets, types of fat and carbohydrates, animal strains, and sex, among others, are used in the studies, which makes it difficult to compare the results and to better evaluate and determine the best way to induce obesity in an animal model. World Health Organization.

However, a direct comparison between Wistar and Sprague-Dawley Imduced Rat as models of high-fat HF diet-induced obesity has not been adequately evaluated so far. In rats, Wistar and Sprague-Dawley SD Outbred Rat are preferentially used standard models, which are characterized by obesity, hyperglycemia, hypertriglyceridemia, and hyperleptinemia, mimicking the pathophysiology of human obesity and metabolic syndrome. Partial Pancreatectomy Diabetic Model. Online Inquiry Name:. In the past decades, obesity and associated metabolic complications have reached epidemic proportions. Keywords: animal models; diet-induced obesity; high-fat diet; metabolic syndrome; microbiota; obesity.

For Research Use Only. To assess some of the features of the metabolic syndrome, oral glucose tolerance tests, systolic blood pressure measurements and blood biochemical analysis were performed diet induced obesity the study. As one of industry leaders in animal models modell, Creative Biolabs is professional in tailoring high fat diet-induced obesity model to satisfy our clients' specific research project. Obesity and Animal Models Obesity, which has resulted in increasing healthcare burden and decreasing life expectancy, is a key feature of the metabolic syndrome, a set of interrelated risk factors for cardiovascular disease and diabetes, that also includes dysglycemia, raised blood pressure, elevated triglyceride levels, and low high-density lipoprotein cholesterol levels. Abstract In the past decades, obesity and associated metabolic complications have reached epidemic proportions. Also, they may be the best choice for evaluating prospective therapeutics.

MeSH terms

Keywords: animal models; diet-induced obesity; high-fat diet; metabolic syndrome; microbiota; obesity. Wistar and SD rats were assigned for 2 experimental groups for 17 weeks: standard St and high-fat HF diet groups. For the study of these pathologies, a number of animal models have been developed. The gut microbiota of SD rats was less abundant in Bacteroides and Prevotella but richer in Bifidobacterium and Lactobacillus comparatively to the gut microbiota of Wistar rats. HF diet increased weight gain, body fat mass, mesenteric adipocyte's size, adiponectin and leptin plasma levels and decreased oral glucose tolerance in both Wistar and SD rats.

Wistar and SD rats were assigned for 2 experimental groups for 17 weeks: standard St and high-fat HF diet groups. Streptozotocin-Nicotinamide-Induced Diabetic Model. To assess some of the features of the metabolic syndrome, oral glucose tolerance tests, systolic blood pressure measurements and blood biochemical analysis were performed throughout the study. In mice, the B6 mouse is a particularly good model because when fed ad libitum with a high-fat diet, they develop obesity, hyperinsulinemia, hyperglycemia, and hypertension, which, to a very great degree resemble human metabolic derangements.

Mice aged 6 to 8 weeks can be considered young adult mice [ 15 ]. A study further explored the viability of the diet-induced obesity model by testing several mice for their reactivities to a high-caloric diet. PMC

Epidemiological studies have shown a positive relationship between high fat diet induced obesity model fat intake and obesity. In addition, body weight was recorded weekly. Inducwd contrast, significant difference in vascular function was evident, if the PVAT is left intact. The model is used to challenge beliefs about the causes of obesity in the population, as a group of scientists decided to test the notion that obesity is a result of overnutrition and could be controlled by limiting meal sizes. Kaji, N. In this sense, although high-fat diets have a high sacietogenic potential, which reduces food consumption, the consumption of a small amount is able to efficiently increase weight and body fat due to the high caloric intake [ 7 ]. Isoflurane is a known vasodilator 58 and therefore one could argue that the performed measurements for vascular function assessment may be biased.

Nevertheless, the modulation of the gut microbiota by HF diet was similar in both strains, except for Clostridium leptum that was only reduced in Wistar rats fed with HF diet. Streptozotocin-Nicotinamide-Induced Diabetic Model. In brief, lots of factors need to be considered carefully when choosing an experimental model, including diet composition, mouse background, gender, environmental factors and so on.

Thus, myocyte hypertrophy is considered a mechanism of adaptation in response to several stimuli, such as increased cardiac output due to the metabolic demand caused by obesity condition Mill and Vassallo, ; Rahmouni et al. Purified ingredient diets consist of highly refined ingredients with almost no non-nutrient supplements. To address this sexual dimorphism, future experiments with female mice are needed. For example, Apodemus chevrieri is used in studies of metabolism because the length of the day determines their metabolism instead of their diet.

Furthermore, the spatial induced obesity model in housing organisms can affect the brain chemistry in social creatures like mice and rats, making them more vulnerable to slower brain development and abnormalities due to the lack of social interactions. For example, mice were put on a high-fat diet, but given either tap water, green tea, or Goishi tea to drink. Appl Physiol Nutr Metab. However, according to our results, this pathway is partially activated in this model of obesity, since the Akt inhibition did not change the endothelium-mediated dilation with either acetylcholine or leptin to the same level as observed in C animals.

Some inbred strains of mice are sensitive and will show marked weight gain when fed a high fat diet, whereas other strains are resistant and demonstrate weight gain similar to mice fed a control diet.
