Harlan Teklad 诱导动物NAFLD and NASH饲料

Teklad diet, bedding and enrichment    Teklad laboratory animal diets   Custom research diets   NAFLD and NASH

诱导啮齿动物NAFLD/NASH的饮食方法可分为两大类：

  • 长期喂饲可诱发肥胖、代谢综合症及轻微纳什或
  • 短时间喂饲可诱发严重纳什的肝脏特征而不引起肥胖或胰岛素抵抗的饮食。

下表突出了上述两个类别的饮食选择。有关NAFLD/NASH模型的更完整描述，请参见表后面的下拉菜单。

Dietary methods to induce NAFLD/NASH in rodents can be split into two common categories:

  • diets fed for longer periods of time to induce obesity, metabolic syndrome, and mild NASH or
  • diets fed for short periods of time to induce hepatic features of severe NASH without inducing obesity or insulin resistance

This page provides further information on dietary methods to induce NAFLD/NASH. We’ve also prepared a downloadable NASH/NAFLD mini paper.

The tables below highlight diet options from both of the above categories. For more complete descriptions of NAFLD/NASH models see the drop down menus that follow the tables.

Diets inducing obesity, metabolic syndrome and mild NAFLD/NASH

Western or fast food style diets fed to induce NASH with metabolic syndrome contain 40 – 45% kcal from milkfat (a fat source high in palmitate) with added cholesterol (0.15 – 2%) and are high in sucrose (>30%). Dietary palmitate and cholesterol have both previously been associated with the progression from simple steatosis to NASH.

Examples:

  • TD.88137       Adjusted Calories Diet (42% from fat)
  • TD.96121       21% MF, 1.25% Chol. Diet
  • TD.120528     42% Kcal/Fat Diet (Incr. Sucrose, 1.25% Chol.)

Research use:

These diets can induce obesity, metabolic syndrome, and simple steatosis within nine weeks of feeding. Increased hepatic inflammation has been observed after 12 weeks of feeding. NASH typically requires longer feeding with fibrosis developing within nine months and late stage fibrosis including hepatic ballooning occurring after 14 – 20 months of feeding. Increasing dietary sucrose (~41%) and cholesterol (~1.25%) accelerates the NASH phenotype with steatosis, inflammation and hepatocyte ballooning observed within 12 weeks. In addition to feeding a high fat diet, providing a glucose/fructose mixture in the drinking water may further promote NASH development.

The American Lifestyle-Induced Obesity Syndrome (ALIOS) model involves feeding the “American fast food” diet high in trans-fats and sugar. Dietary trans-fats from hydrogenated vegetable shortening (HVO) are associated with increased insulin resistance and hepatic inflammation in rodent NASH models. In addition to diet, a glucose/fructose solution is added to the drinking water and sedentary behavior promoted by removing the overhead cage feeders in this model.

Examples:

  • TD.06303       22% HVO Diet
  • TD.120330     22% HVO + 0.2% Cholesterol Diet
  • TD.130885     ALIOS with Added Sugar

Research use:

The ALIOS model develops obesity with insulin resistance, elevated ALT levels, and steatosis within 16 weeks. Increased inflammation and early development of fibrosis have been observed at 6 months. Severe steatosis with fibrosis and inflammation develops within 12 months of feeding with 50% of the mice reportedly developing hepatic neoplasms. Adding cholesterol (0.2%) to the American Fast Food diet may accelerate NASH phenotype development.

The Fructose, Palmitate, Cholesterol and Trans-Fat (FPC) diet is a recent NASH diet that includes Western and ALIOS model diets to achieve both metabolic and hepatic NASH features within an accelerated time frame. Key features of the FPC diet include 1) a lower Met content than typical rodent diets by decreasing total protein without supplementing sulfur amino acids; 2) choline supplementation is lower than typical but is not considered deficient; 3) high in sucrose (~34% by weight); 4) 1.25% cholesterol; 5) 52% kcal from fat with fat sources including milkfat fat, palmitic acid and hydrogenated vegetable shortening to provide trans-fats. Like the ALIOS model, the FPC model also provides a glucose/fructose solution to the drinking water.

Examples:

  • TD.160785     52 kcal/Fat Diet (C16:0, HVO, AMF, Choline/Met)

Research use:

Male C57BL/6J mice fed the FPC diet and provided a glucose/fructose drinking solution developed insulin resistance and NAFLD with inflammation, hepatocyte death, and fibrosis within 16 weeks.

Common diets to induce obesity (DIO) can be fed to induce uncomplicated NAFLD. These high fat diets typically contain 40–60% kcal from fat without supplemented cholesterol or cholate. Simple sugars such as sucrose or fructose can also be supplemented via diet or water to progress the fatty liver phenotype. Diets can be in pellet or powder/dough form depending on the formula. Some models require limited physical activity and in those cases diets can be fed inside the cage. For more information see our Diet Induced Obesity page.

Examples:

  • TD.08811       45%kcal Fat Diet (21% MF, 2% SBO)
  • TD.06414       Adjusted Calories Diet (60/Fat)

Research use:

In susceptible rodent models, high fat diets are commonly used to induce NAFLD with obesity and insulin resistance common metabolic features associated with NASH in humans. However, the degree of NASH pathology (steatosis, inflammation, and fibrosis) is limited or mild and varies depending on the animal model, length of feeding, and dietary components.

Diets to induce severe hepatic NAFLD/NASH without obesity or metabolic

COLLAPSE ALL TABS

Originally formulated to induce mild atherosclerosis in wild-type rodents, high fat diets containing added cholesterol (1 – 1.25%) and cholate (0.5% as sodium cholate or cholic acid) have also been useful in inducing NASH. This diet option includes purified “Western” style diets with increased cholesterol and cholate and also hybrid diets. Hybrid diets were originally developed by Beverly Paigen and colleagues by mixing a natural ingredient mouse diet in a 3:1 ratio with a concentrated purified diet (containing 5% cholesterol and 2% sodium cholate) resulting in a diet containing ~15.8% fat, 1.25% cholesterol, and 0.5% sodium cholate. Although a less refined approach, the hybrid diet is associated with increased gallstone formation and liver damage as compared to similar purified diets.

Examples:

  • TD.02028       Atherogenic Rodent Diet
  • TD.88051       Cocoa Butter Diet and Purina Mouse Chow
  • TD.09237       15% AMF Diet (1% Chol, 0.5% NaChol)

Research use:

Atherogenic diets are able to induce varied degrees of NASH with increased hepatic inflammation with early fibrosis observed after ten weeks of feeding. However, the metabolic profile typical in human NASH (obesity with insulin resistance) is not recapitulated in this model with animals typically maintaining similar body weights as control fed groups without the development of metabolic syndrome.

Methionine and choline deficient (MCD) diets are amino acid defined rodent diets deficient in methionine and choline, high in sucrose (>40% by weight) with ~10% corn oil by weight. Methionine and choline deficiency decreases fat oxidation and export of fat from the liver. Dietary sucrose is necessary for hepatic lipid accumulation and oxidation. The polyunsaturated fat in corn oil promotes hepatic lipid oxidation.

Example:

  • TD.90262       Methionine/Choline Deficient Diet

Control:

  • TD.94149       Amino Acid Control Diet

Research use:

Steatosis, increased serum alanine aminotransferase (ALT), inflammation, and hepatic fat oxidation has been observed within three weeks of feeding the MCD diet with fibrosis development after six weeks. This dietary model does not produce metabolic syndrome (an aspect of NASH in human models) and progressive weight loss (up to 40%) is associated with the MCD diet feeding.

Dietary models of NAFLD/NASH continue to evolve with the goal of more accurately recapitulating both the metabolic and hepatic symptoms of human disease. Commonly researchers are studying the synergistic effects of various NASH dietary features to accelerate progression of the model and severity of liver disease.

A Teklad nutritionist can work with you to formulate new diets in order to investigate novel dietary models of NAFLD/NASH.

The choice of control diet is dependent on the specific research goal. Many researchers choose to compare their NAFLD/NASH diet-fed animals to animals fed a natural ingredient, grain-based diet (also referred to as standard diet or chow). These diets differ in the source and level of nutrients as well as in the presence of non-nutritive factors (such as phytates or phytoestrogens).

Depending on what your main comparisons are, it may be suitable to have a grain-based diet as your control/reference group. However, making such comparisons limits inferences to dietary patterns versus a specific dietary component. In some cases, such as those studies feeding amino acid defined diets like the MCD model, a matched control diet is recommended given the very different formulations and protein sources of grain-based diets.

When making inferences about specific nutrients within the diet an ingredient matched, low fat control diet may be necessary. There are many options with different levels and types of fat in addition to different types of carbohydrate ranging from sucrose (highly refined and digestible) to corn starch (refined, but more complex) to resistant starch (refined, but not fully digestible).

A very basic purified control diet would be AIN-93M TD.94048 or AIN-93G TD.94045. AIN-93 diets have a moderate amount of sucrose at ~10% with fat from soybean oil providing a healthy fatty acid profile.

控制饮食的选择取决于具体的研究目标。许多研究人员选择比较他们的NAFLD/纳什饮食喂养的动物和喂养一种天然成分的动物，谷物为基础的饮食(也称为标准饮食或周食)。这些饮食在营养来源和水平以及非营养因素(如植酸盐或植物雌激素)存在的情况下存在差异。

根据您的主要比较，它可能适合作为您的对照/参考组谷物基础的饮食。然而，这样的比较限制了对饮食模式和特定饮食成分的推断。在某些情况下，如那些研究喂食氨基酸定义的饮食，如mcd模型，建议一个匹配的对照饮食，考虑到非常不同的配方和蛋白质来源的谷物为基础的饮食。

当对饮食中的特定营养成分做出相应的推断时，低脂控制饮食可能是必要的。除了不同类型的碳水化合物外，还有许多不同水平和类型的脂肪，从蔗糖(高精制和可消化)到玉米淀粉(精制，但更复杂)，再到抗性淀粉(精制，但不能完全消化)。

一种非常基本的纯正控制饮食将是-9300万。TD.94048或者是93g TD.94045。AIN-93日粮中含有适量的蔗糖~10%，大豆油中的脂肪提供了健康的脂肪酸谱。

Harlan Teklad Diet ingredients

Teklad diet, bedding and enrichment + Teklad laboratory animal diets + Custom research diets + Diet ingredients

You may want to prepare your own diet at your research site or facility, and if that is the case, you depend on the ingredients being of the highest quality. Envigo can provide you with many of the same ingredients used to produce our advanced Teklad custom research diets so you can develop your own formula. And as always, our nutritional experts are here to help you make the best decisions for your ingredients and ultimate formulation.

Our ingredients

We offer several ingredients for individual sale so that you can develop your own blends.

“VFT” casein

  • “Vitamin-free” test casein (alcohol-extracted) is best suited for purified test diet formulas where fat or vitamin content needs to be precisely controlled
  • The reduced levels of many vitamins in VFT casein make it the preferred protein source for many vitamin studies. Thus, the nickname “Vitamin-free” was given to the extracted casein many years ago

Vitamin mixes

  • The common vitamin mixes shown below use sucrose or corn starch as a carrier
  • Customized vitamin mixes may use cellulose if a non-nutritive carrier is necessary
  • Vitamin mixes are formulated with a diet inclusion rate in mind. Using more or less than recommended could impair the health of your laboratory animal
  • For those preparing their own diets, vitamin premixes are an efficient way to add vitamins to a diet
  • Vitamin mixes should be stored at 4 degrees celsius or lower upon receipt. Storage at –20 degrees celsius is recommended if the mix will be used beyond 1 month
  • Minimum order is 500 g for both stock and custom vitamin mixes
  • Our available vitamin mixes are commonly used in diets, and are available from stock
  • Vitamin mixes are shipped within a few days of order

Our Formula examples

  • CA.40060 Teklad vitamin mix
  • CA.40077 AIN-76A vitamin mix
  • TD.94047 AIN-93 vitamin mix

Mineral mixes

  • The common mineral mixes shown below as examples use sucrose as a carrier
  • Customized mineral mixes could use cellulose or no carrier if a non-nutritive carrier is necessary
  • Our mineral mixes are formulated with a diet inclusion rate in mind. Using more or less than recommended could impair the health of the animal
  • For those preparing their own diets, mineral premixes are an efficient way to add minerals to a diet
  • Mineral mixes should be stored in a dry cool environment and used within a year of receipt. The minimum order is 500 g for both stock and custom mineral mixes
  • These mineral mixes are commonly used in diets, and are available from stock
  • Our mineral mixes are shipped within a few days of order

Formula examples:

  • CA.170915 AIN-76 mineral mix

你可能想要在你的研究地点或设施准备你自己的饮食，如果是这样的话，你取决于成分是最高的质量。Envigo可以为您提供许多相同的成分，用于生产我们先进的特克拉德定制研究饮食，以便您可以开发自己的配方。和往常一样，我们的营养专家在这里帮助您为您的配料和最终配方做出佳决定。

我们的配料

我们提供几个配料供个人销售，以便您可以开发自己的混合。

“VFT”酪蛋白

  • “无维生素”测试酪蛋白(酒精提取)最适合于那些需要精确控制脂肪或维生素含量的纯正试验饮食配方。
  • VFT酪蛋白中许多维生素含量的降低使得它成为许多维生素研究的首选蛋白质来源。因此，“无维生素”的绰号是在许多年前给提取出来的酪蛋白起的。

维生素混合物

  • 以下常见的维生素混合物使用蔗糖或玉米淀粉作为载体。
  • 定制的维生素混合物可能使用纤维素，如果非营养载体是必要的。
  • 维生素混合物的制定考虑到了饮食中的包容率。多用或少用会损害你的实验动物的健康。
  • 对于那些自己准备饮食的人来说，维生素预混剂是向饮食中添加维生素的一种有效方法。
  • 维生素混合物应储存在4摄氏度或更低的接收。如果使用时间超过1个月，建议使用摄氏-20度。
  • 库存和定制维生素混合物的最低订购量为500克。
  • 我们可用的维生素混合物通常用于饮食，并可从库存中获得。
  • 维生素混合物在订购后几天内发货。

我们的公式示例

  • CA.40060 特克拉德维生素混合物
  • CA.40077 AIN-76A维生素混合物
  • TD.94047 AIN-93维生素混合物

矿物混合物

  • 下面所示的常见矿物混合物是以蔗糖为载体的。
  • 如果需要非营养的载体，定制的矿物混合物可以使用纤维素，也可以不使用载体。
  • 我们的矿物质混合物是根据饮食包容率来制定的。多用或少用会损害动物的健康。
  • 对于那些自己准备饮食的人来说，矿物预混料是向饮食中添加矿物质的有效方法。
  • 矿物混合物应存放在干燥、凉爽的环境中，并在收到后一年内使用。库存和自定义矿物混合物的最低订购量为500克。
  • 这些矿物混合物通常用于饮食，并可从库存中获得。
