Mammal Obesity Model

Overview of Mammal Obesity Model

Obesity, which is caused by factors such as genetics or nutritional supply and results in excessive energy in the form of fat in the body, poses a great threat to human health. Many factors affect the body produce obesity, such as genetic factors, nutritional factors, developmental stage, gender, etc. Protheragen has established different In Vivo Obesity Models for different aspects to improve the reliability of the results. These models not only help us to unravel the complexity of obesity but also are a key tool to promote anti-obesity preclinical research.

Mammal Obesity Model Holds Exponential Possibilities

Workflow

The construction of the mammalian obesity model mainly includes the selection of suitable experimental animals, the design of an induction program, regular monitoring of body weight, and evaluation of obesity-related indicators. Meanwhile, our researchers pay more attention to feed transition, nutritional balance, individual differences, and ethical review to ensure the accuracy and reliability of the model construction.

Results: This article focuses on the effects of diet-induced obesity on the physiology, metabolism, and health status of mouse offspring. The researchers used a specific high-fat diet (HFD) to induce obesity in mice, which were used as female offspring. It was found that the offspring mice born to diet-induced obese mothers had significantly higher body weights and body fat ratios than the offspring of the normal-diet mothers during postnatal growth and development. There were differences in the expression of fat metabolism-related genes in the offspring mice of obese mothers. These differences may be related to their metabolic abnormalities and increased susceptibility to obesity.

Frequently Asked Questions

What are the indicators of animal model evaluation?

  • General observations: General observation refers to the observation of body mass, amount of water intake, mental status, dorsal hair color, and amount of feces of the experimental animals during the modeling period.
  • Observation of morphological indicators: Morphological indicators mainly include the observation of body mass changes, the relative mass of internal organs, and the determination of associated fat.
  • Functional and histopathologic observations of the liver: The liver is an important organ for human metabolism. Obesity tends to affect liver function and change the morphology of liver cells. We mainly provide liver function and hepatocyte testing.
  • Energy metabolism observations: Metabolic data generally include respiratory exchange efficiency (ratio of CO2 release to O2 consumption), spontaneous activity, and heat production (energy metabolism per unit of body mass per hour).
  • Serum-related biochemical indicators: Obesity leads to abnormalities in blood lipid metabolism. Serum levels of total cholesterol (TC), triglyceride (TG), low-density lipoprotein (LDL), and high-density lipoprotein (HDL), are commonly used indicators to study abnormalities in blood lipid metabolism.

What are the factors affecting modeling?

The main factors affecting modeling include animal species, diet formulation, obesity resistance, age, and sex.

The mammalian obesity models Protheragen provides are used as an excellent tool for in-depth studies of metabolic diseases. Our company is committed to solving all the problems encountered by our clients in preclinical studies of anti-obesity. Whatever your questions, feel free to contact us!
