Experimentally induced rodent models of type 2 diabetes

Area of Science:

• Endocrinology and Metabolism
• Animal Models in Biomedical Research
• Diabetology

Background:

• Type 2 diabetes (T2D) is a significant global health issue, particularly prevalent in developing nations.
• Rodents are favored animal models for diabetes research due to practical advantages.
• Experimentally induced non-genetic models are widely used for T2D research.

Purpose of the Study:

• To comparatively evaluate experimentally induced rodent models for type 2 diabetes research.
• To analyze the limitations, advantages, and disadvantages of various non-genetic T2D models.
• To guide researchers in selecting appropriate animal models for their specific research questions.

Main Methods:

• Review of established non-genetic rodent models for T2D induction.
• Comparative analysis of models including alloxan/streptozotocin (STZ), high-fat diet, and fructose-fed models.
• Evaluation of model limitations, advantages, and developmental criticality.

Main Results:

• Several non-genetic models exist, including STZ, partial pancreatectomy, high-fat diet, fructose-fed, nicotinamide-STZ, MSG, and IUGR models.
• No single model perfectly replicates all human T2D pathogenesis.
• Each model presents unique benefits and drawbacks for diabetes research.

Conclusions:

• Selecting the optimal T2D rodent model requires careful consideration of research objectives and model-specific limitations.
• Understanding the comparative strengths and weaknesses of different models is crucial for successful diabetes research.
• Further refinement of existing models or development of new ones may be necessary to better mimic human T2D.
