Diabetes Animal Model Development
Diabetes mellitus, commonly known as diabetes, is a group of metabolic disorders characterized by chronically elevated blood glucose levels. This condition arises due to insufficient production of insulin, impaired response of cells to insulin, or impaired glucose metabolism. Animal models have proven essential in understanding the faulty mechanisms underlying the co-morbidities associated with both type 1 (T1DM) and type 2 (T2DM) diabetes in patients, as well as for assessing innovative treatments for these diseases. At BioVenic, we provide tailored solutions for developing animal models of diabetes that cater to both T1DM and T2DM across multiple species.
Background
The majority of diabetics fall into two main categories: T1DM and T2DM, each with its own unique pathophysiological characteristics. Diabetes can cause a variety of complications that affect the performance and health of the animal. Therefore, it is necessary to develop animal models to study the mechanism of diabetes and to develop therapies for animal diabetes.
T1DM
- Cause: The body's immune system attacks and destroys beta cells in the pancreas responsible for producing insulin. This results in a lack of insulin, a crucial hormone for regulating blood sugar levels and facilitating glucose uptake by cells.
- Influencing Factors: Family history may influence the risk
- Management: Individuals with T1DM rely on lifelong insulin therapy to control their blood glucose levels.
T2DM
- Cause: insulin resistance, wherein the body's cells do not respond effectively to insulin, accompanied by a relative insulin deficiency.
- Influencing Factors: This form of diabetes is often associated with factors like obesity, sedentary lifestyle, and/or genetic predisposition.
- Management: T2DM is typically managed through lifestyle modifications and oral medications.
Diabetes Animal Model Development
Animal models have been indispensable in testing innovative medicinal approaches since the early testing of insulin in dogs almost a century ago. Based on the methodologies used for their development, diabetes animal models can be categorized into chemically induced, genetically/spontaneously induced, virus-induced, surgically constructed, and diet/nutrition-induced animal models.
- Chemically Induced Diabetes Animal Model Development
Chemicals such as alloxan and streptozotocin (STZ) have been commonly used to produce animals with T1DM, although other agents such as cyclophosphamide and multiple low-dose streptozotocin (MLD-STZ) have also been used. Administration of sub diabetogenic doses of STZ or alloxan can lead to impaired glucose tolerance, which closely resembles the early stages of T2DM. BioVenic can assist in selecting the appropriate dose of these drugs to induce diabetes depending on factors such as species, route of administration and nutritional status.
- Genetically/Spontaneously Induced Diabetes Animal Model Development
Diabetes animal models for both T1DM and T2DM have been developed through spontaneous induction and genetic engineering. Numerous rat and mouse models, induced either genetically or spontaneously, have been extensively utilized in diabetes research. We have established cutting-edge Animal Breeding and Genetics technology platforms that cater to multiple species. By leveraging our expertise, we can provide assistance in your genetically/spontaneously induced diabetes animal model development project.
- Virus-Induced Diabetes Animal Model Development
In order to create animal models for T1DM, viruses have been utilized to target and eliminate insulin-producing β cells in the pancreas. Prominent viruses employed in these models include Coxsackie B virus (CBV), Encephalomyocarditis virus (EMCV), Lymphocytic choriomeningitis virus (LCMV), Cytomegalovirus (RCMV), and the Kilham virus. By tailoring our approach to your project and research goals, we can offer specific solutions for inducing diabetes using viruses.
- Surgically Constructed Diabetes Animal Model Development
For the study of T1DM, essential surgical techniques involve complete removal of the pancreas (pancreatectomy), transplantation of insulin-producing islets, and surgical removal of the thymus gland (thymectomy). Surgical methods to induce T2DM primarily focus on reducing the mass of pancreatic β cells. At BioVenic, we offer a range of products and services to assist you in building your own diabetes animal models through surgical procedures.
- Diet/Nutrition-Induced Diabetes Animal Model Development
Selective breeding is an effective approach to produce animals with impaired glucose tolerance. BioVenic offers clients various dietary and nutritional strategies to generate animal models for studying the progression of T2DM and testing potential treatments. Our common methods include the use of high fat diets (HFD) to induce obesity and insulin resistance, as well as energy dense diets (ED). In addition, we can provide solutions for combining diet with low-dose STZ to create HFD/ STZ animal models of T2DM.
- Combinations-Induced Diabetes Animal Model Development
By combining chemical agents with HFD, nicotinamide, or genetically susceptible animals, conditions can be induced that closely resemble T2DM, marked by insulin resistance and progressive β cell dysfunction. These combinations enable researchers to generate a more controlled and reproducible T2DM phenotype in animals. With our integrated solutions, BioVenic offers researchers a tailored approach for developing diabetes animal models.
- Diabetes Animal Model Validation
In order to establish reliable and successful animal models for understanding disease susceptibility and pathogenesis in diabetes, validation is crucial. We offer a range of assays for diabetes biomarkers (such as insulin, serum glucose, and C-peptide) in different animal species. These assays not only help confirm the induction of diabetes in animal models but also allow for the measurement of important biomarkers in your diabetes research through our Animal Nutrition and Metabolism Analysis services.
