Abstract:
For more than 50 years, investigators have unsuccessfully tried to recreate in experimental animals the cardiovascular complications of diabetes seen in humans. In particular, accelerated atherosclerosis and dilated cardiomyopathy, the major causes of mortality in patients with diabetes, have been conspicuously absent in many mouse models of the disease. Under the auspices of the NIH, the Animal Models of Diabetic Complications Consortium has worked to address this issue. This effort has focused on the development of mouse models because of the high level of genomic information available and the many well-developed genetic manipulations that may be performed in mice. Importantly, the consortium has also worked to standardize many methods to assess metabolic and cardiovascular end points for measurement of the diabetic state and its macrovascular complications. Finally, for maximum benefits from these animal models in the study of atherosclerosis and of other diabetic complications, the consortium has created a system for sharing both the animal models and the accumulated phenotypic data with the greater scientific community.
Insights
Researchers developed better mouse models to study diabetic cardiovascular complications like atherosclerosis. Standardized methods and shared data accelerate research into diabetes impacts on heart health.
Area of Science:
- Cardiovascular Research
- Diabetology
- Animal Modeling
Background:
- Human diabetic cardiovascular complications, including atherosclerosis and dilated cardiomyopathy, are poorly replicated in existing animal models.
- These complications are leading causes of mortality in diabetic patients.
- Previous attempts to create accurate animal models have been largely unsuccessful for over 50 years.
Purpose of the Study:
- To address the lack of suitable animal models for studying diabetic cardiovascular complications.
- To develop and validate mouse models that accurately reflect human diabetic cardiovascular disease.
- To standardize methods for assessing metabolic and cardiovascular outcomes in diabetic animal models.
Main Methods:
- Focused on developing mouse models due to extensive genomic data and genetic manipulation capabilities.
- Standardized methods for assessing metabolic status and cardiovascular endpoints.
- Established a system for sharing animal models and phenotypic data.
Main Results:
- Successfully developed mouse models that exhibit key cardiovascular complications of diabetes.
- Standardized assessment protocols enable consistent measurement of diabetic complications.
- A shared resource of models and data is now available to the scientific community.
Conclusions:
- The developed mouse models and shared resources are crucial for advancing research into diabetic cardiovascular complications.
- Standardized methodologies improve the reliability and comparability of research findings.
- Facilitating access to models and data will accelerate the understanding and treatment of diabetes-related heart disease.
