Obesity is a growing public health concern with complex causes. Rodent models, particularly rats, are vital for studying human obesity through induced neuroendocrine, dietary, or genetic changes.
Area of Science:
- Obesity research
- Animal models in biomedical research
- Public health challenges
Context:
- Obesity's multifactorial etiology presents a significant public health issue.
- High prevalence of obesity and its comorbidities impact population health.
- Rodent models offer high genomic similarity to humans for disease simulation.
Purpose:
- To review established methods for inducing obesity in rat models.
- To highlight the utility of rodent models in understanding human obesity.
- To provide an overview of common obesity induction techniques in rats.
Summary:
- Obesity is a complex, multifactorial condition with significant public health implications.
- Rat models are valuable for studying human obesity due to genomic homology.
- Methods for inducing obesity in rats include neuroendocrine, dietary, and genetic manipulations.
Impact:
- Facilitates research into obesity's mechanisms and comorbidities.
- Supports the development of novel therapeutic strategies for obesity.
- Enhances understanding of obesity's impact on public health outcomes.
