简介：
Overview
This study presents a protocol to assess the basal metabolic rate and oxidative capacity of thermogenic adipocytes in obese mice. The method provides insights into energetic balance variations in mice, which can facilitate understanding of physiological processes related to body weight changes.
Key Study Components
Research Area
- Metabolic rate assessment
- Obesity research
- Thermogenic adipocyte function
Background
- Importance of understanding energy expenditure in obesity
- Role of brown fat in energy expenditure
- Need for accurate measurement techniques in metabolic studies
Methods Used
- Indirect calorimetry for measuring oxygen consumption and CO2 production
- Use of eight-week-old female mice as model organisms
- Controlled environmental enclosure settings
Main Results
- Energy expenditure varies between diets, highlighting differences in fat and carbohydrate oxidation
- High-fat diets lead to increased energy expenditure without altering lean mass
- Beta-3 agonist injections significantly enhance energy expenditure through thermogenic activation
Conclusions
- This protocol aids in the investigation of obesity-related diseases and energy balance mechanisms.
- Findings contribute to understanding nutrient preference and thermogenesis in metabolic research.
