Diet, High-Fat

A high-fat diet is a dietary pattern characterized by a high intake of fats, often exceeding 30% of total daily caloric intake.
This type of diet is commonly associated with research on metabolic disorders, weight management, and the impact of dietary fats on health.
High-fat diets may include a variety of fat sources, such as saturated, monounsaturated, and polyunsaturated fats, and can be studied in the context of animal models or human clinical trials.
Researchers leveraging high-fat diet protocols may focus on investigating the physiological effects, potential health benefits or risks, and underlying mechanisms involved in the body's response to this dietary approach.

Due to the overwhelming sparsity in microbiome datasets, some filtering is required in order to infer microbe-metabolite interactions. We chose to filter out microbes that appear in less than 10 samples, since these microbes don’t have enough information to infer which metabolites are co-occurring with them. In other words the mmvec model has too many degrees of freedom to perform inference on these microbes. For the cystic fibrosis study, there were 172 samples and after filtering there were 138 unique microbial taxa and 462 metabolite features. For the biocrust soils study, there were 19 samples and after filtering there were 466 unique microbial taxa and 85 metabolite features. For the murine high fat diet study, there were 434 samples and after filtering there were 902 microbes and 11978 metabolites. For the IBD dataset, there were 13920 features in the c18 LCMS dataset, 26966 features in the c8 LCMS dataset and 562 taxa. Cross validation was performed across all studies to evaluate overfitting. In the desert biocrust soils experiment, 1 sample out of 19 samples was randomly chosen to be left out for cross-validation. In all of the other studies, 10 samples were randomly chosen to be left out for cross-validation. All of the analyses can be found under https://github.com/knightlab-analyses/multiomic-cooccurences.

Example 18

It was examined whether the oxyntomodulin derivative-immunoglobulin Fc conjugates show excellent body weight-reducing effects in vivo.

Specifically, 6-week-old normal C57BL/6 mice were fed a high fat diet of 60 kcal for 24 weeks to increase their body weight by approximately 50 g on average, and subcutaneously administered with oxyntomodulin derivative (SEQ ID NO: 23, 24 or 25)-immunoglobulin Fc conjugates at a dose of 0.03 or 0.06 mg/kg/week for 3 weeks. Thereafter, changes in the body weight of the mice were measured (FIG. 12 and FIG. 13). FIG. 12 and FIG. 13 are graphs showing changes in body weight of mice according to the type and administration dose of oxyntomodulin derivative-immunoglobulin Fc conjugates. As shown in FIG. 12 and FIG. 13, as the administration dose of the oxyntomodulin derivative-immunoglobulin Fc conjugates was increased, the body weight was reduced in direct proportion, even though there were differences between the types of the oxyntomodulin derivative-immunoglobulin Fc conjugates, suggesting that the oxyntomodulin derivative-immunoglobulin Fc conjugates reduce the body weight in a dose-dependent manner.

Example 1

To examine the function of ACATs in obesity, the expression patterns of ACAT1 and ACAT2 genes, and their gene products during adipogenesis of murine 3T3-L1 preadipocytes in vitro were examined. ACAT1 mRNA level was markedly increased in adipocytes from 2 days after initiation of adipogenesis (i.e., D2) as judged by real-time PCR assay (FIG. 1). However, ACAT2 mRNA level was similar between preadipocytes (D0) and mature adipocytes (D6) while a temporal reduction of ACAT2 level was observed at D2 (FIG. 1). In addition, white adipose tissue (WAT) isolated from high fat diet-induced obese mice displayed elevated mRNA level of ACAT1 and reduced mRNA level of ACAT2 when compared with those in lean mice as judged by real-time PCR assay. Leptin level was measured in WAT from lean and obese mice to ensure the development of obesity (FIG. 2). In addition, brown adipose tissue (BAT) from obese mice exhibited elevated levels of both ACAT1 and ACAT2. Uncoupling protein-1 (UCP-1) level was measured in BAT from lean and obese mice as a BAT-specific marker protein (FIG. 2). However, liver from lean and obese mice exhibited similar levels of ACAT1 and ACAT2 (FIG. 2).

There were no significant differences between results from recordings or analyses from samples obtained on lactation d 10 and d 17, except for piglet performance. The mean of values observed for d 10 and d 17 were therefore used in the statistical analysis. All data were analyzed using the PROC MIXED procedure of SAS (version 9.4, SAS Institute Inc). For gene expression data, the delta Ct values (ΔCt = Ct of the target gene – mean Ct of the reference genes) of genes were used for statistical analysis. All the data were analyzed in 2 ways: as orthogonal contrasts between low-fat and the four high-fat diets, and by multiple comparisons between the four high-fat diets. Treatment differences between groups were determined using the PDIFF option, and the results were expressed as least-squares means with pooled-standard error, except for the genes relative abundance, which were reported as a mean ± 95% confidence limits. The CORR procedure of SAS was used to analyze the correlations of digestible FA intake and milk FA output, and the amounts of de novo synthesized fat using the two prediction methods. For the statistical evaluation, P ≤ 0.05 was declared as a significant response, while P ≤ 0.10 was declared as a tendency.

All animal procedures were performed under a project licence (PPL P94B395E0) approved by the U.K. Home Office under the Animals (Scientific Procedures) Act 1986 and the University of Aberdeen ethics review board. Studies were performed following the recommendations in the ARRIVE guidelines under guidance by the Veterinary Surgeon and Animal Care and Welfare Officers of the institutional animal research facility. Thus, all methods were performed in accordance with the relevant guidelines and regulations. Male LDLR−/− mice, aged 4–6 weeks, were purchased from The Jackson Laboratory (supplied by Charles River UK Ltd), male and female ApoE−/− mice were bred in-house (University of Aberdeen). All mice were fed chow diet until 12 weeks of age then placed into three groups and fed the following diets (all Research Diets Inc.) to induce atherogenesis and NAFLD for 14 weeks: control (10% kCal fat D14121001) or high-fat/high-cholesterol diet (HFD, 40% kCal fat from cocoa butter and soybean oil, 34.5% kcal and 5.5% kcal respectively, plus 1.25% cholesterol, Clinton/Cybulsky D12108C) + /- 0.04% Fenretinide (FEN-HFD, D18061502,16 (link),27 (link)–29 (link)). Mice were maintained at 22–24 °C on 12-h light/dark cycle with free access to food/water. At week 14, mice were fasted for 5 h and injected intraperitoneally with either saline or insulin (10 mU/g body weight) for 10 min prior to CO2-induced anaesthesia followed by cervical dislocation. Heart and aortic tissues were collected for histological analysis. Peripheral metabolic tissues (liver, muscle and white adipose tissue (WAT)) were frozen in liquid nitrogen and stored at − 80 °C until subsequent analysis.

All experiments detailed herein complied with the regulations formulated by the Institutional Animal Care and Use Committee (IACUC) of the Weizmann Institute of Science (application numbers: 03960618-3, 01200121-2, 03230322-2). Female and male mice were bred and maintained by the Animal Breeding Center of the Weizmann Institute of Science. Housing conditions were: 12-hour dark/light cycle (lights on at 8 am), temperature 22 °C, humidity 30-70%. For comorbidity studies, heterozygous 5xFAD transgenic mice33 (link) (line Tg6799, The Jackson Laboratory) on a C57/BL6-SJL background and age-matched wild-type (WT) controls were used. Genotyping was performed by PCR analysis of ear clipping DNA, as previously described33 (link). Since the C57/BL6-SJL strain carries the retinal degeneration Pde6brd1 mutation, which causes visual impairment in homozygosis (https://www.jax.org/strain/100012), mice were further tested for presence of the allele, as previously described90 (link). To avoid gut microbiota-related cage effects due to coprophagia91 (link), 5xFAD and WT mice were housed together. For the study of the effects of NANA on the immune system in vivo, we used four cohorts of female and male WT mice, and specifically: three cohorts of C57/BL6-SJL mice, age 6.5, 9, and 14 mo; one cohort of C57/BL6 mice, age 11 mo. For the study of the effects of NANA on novelty discrimination, female C57/BL6-SJL 5xFAD and age-matched WT controls were used. To avoid NANA assimilation with coprophagia, NANA-injected mice were housed separately from the PBS-injected controls. All mice were provided with standard chow (calories from proteins: 24%; calories from carbohydrates: 58%; calories from fat: 18%; 2918, Teklad), placed on a hopper integrated with the cage lid, and water ad libitum, and housed in cages enriched with one paper shelter. For comorbidity studies, to induce obesity, at 6-9 weeks of age, mice were switched to a high-fat diet (HFD; calories from proteins: 18%; calories from carbohydrates: 22%; calories from fat: 60%; TD.06414, Teklad), and the food pellet checked twice a week for replenishment. Control mice were kept on standard chow (control diet, CD). Mice allocated for behavioral studies or NANA/PBS injections were switched to a 12-h reversed dark/light cycle (lights on at 8 pm) at least 7 days prior to behavior assessment, and maintained in the regimen until experimental endpoint.

More about "Diet, High-Fat"

High-fat diets (HFDs), also known as high-fat, low-carb (HFLC) diets, are dietary patterns characterized by a significant intake of fats, often exceeding 30% of total daily caloric consumption.
These diets have become a subject of intense research, particularly in the context of metabolic disorders, weight management, and the impact of dietary lipids on overall health.
HFDs can encompass a diverse range of fat sources, including saturated, monounsaturated, and polyunsaturated fats, and are often studied in both animal models (e.g., C57BL/6J mice) and human clinical trials.
Researchers leveraging HFD protocols may focus on investigating the physiological effects, potential health benefits or risks, and underlying mechanisms involved in the body's response to this dietary approach.
In addition to HFDs, related terms and concepts such as D12492, D12451, streptozotocin (STZ), and the TD.88137 diet formulation are also relevant to this area of research.
These specialized diets and compounds are commonly used to induce metabolic disturbances, such as obesity and diabetes, in animal models to study the impact of dietary factors on disease pathogenesis and progression.
