Metabolic disease models – Diet-induced Obesity DIO Mouse Model
Study the efficacy of your novel anti-obesity therapeutics using the DIO mouse model
DIO Mouse Model Characteristics
The diet-induced obesity DIO mouse model represents a physiological approach to studying efficacy of novel compounds against obesity and related metabolic disorders in a preclinical research setting. Maintaining C57BL/6N mice on a Western-style high-fat diet (HFD) comprising 60% fat content, the DIO mouse model develops many hallmarks of metabolic disease such as obesity, insulin sensitivity, elevated fasting blood glucose and insulin resistance. Additionally, using various behavioral phenotyping protocols, at InnoSer we have demonstrated that HF-fed mice show substantial reduction in general activity, nest building capacity as well as memory performance (e.g., during behavioral tests such as Morris Water Maze [MWM]).
Depending on study timelines, this model can be adapted to study varying stages of metabolic dysfunction, including pre-diabetes, type 2 diabetes mellitus (T2DM) and more severe insulin resistance in the setting of Western diet and obesity. Unlike genetic metabolic models such as the db/db mouse model, the DIO model reflects lifestyle-induced obesity seen in humans, providing you with a highly translational mouse model to study efficacy of novel anti-obesity strategies. Combined with InnoSer’s expertise in behavioral neuroscience studies, the DIO mouse model is also suitable to evaluate efficacy of compounds against metabolic disease-associated cognitive dysfunctions which is currently an emerging area of research within the metabolic disease field. Contact us today to discuss how this model can support your research objectives in preclinical metabolic health research.
✓ Mouse model of physiological induction of obesity
✓ Mice show key hallmarks of metabolic disease (obesity, insulin resistance, hyperglycemia)
As a preclinical metabolic CRO, InnoSer’s team delivers you with a range of high-quality in vivo models for key metabolic diseases with different associated risk factors and aetiologias. This selection allows you to test therapeutic efficacy to prevent or reverse insulin resistance, pre-diabetes, obesity type 2 diabetes mellitus (T2DM), and/or MAFLD/MASH (NASH/NAFLD). To study metabolic disease-associated cardiovascular complications and cardiac dysfunction, InnoSer recommends the use of the Western diet-induced diabetic cardiomyopathy rat model.

DIO Mouse Model Sample Data

The diet-induced obesity DIO mouse is a relevant research tool to study efficacy of compounds against various metabolic-disease conditions.
Long-term body weight following 20-week diet. HF mice were significantly heavier compared to chow-fed mice and HFCF mice, whereas HFCF mice were significantly heavier compared to chow fed mice.

The diet-induced obesity DIO mouse is a relevant research tool to study efficacy of compounds against various metabolic-disease conditions, including associated cognitive dysfunctions.
Although these data may indicate that HF diet and HFCF mice show a cognitive deficit in this test, the vast reduction in overall activity (data not shown) in comparison to Chow-fed mice impacts this test.

The diet-induced obesity DIO mouse is a relevant research tool to study efficacy of compounds against various metabolic-disease conditions, including associated cognitive dysfunctions.
HF diet and HFCF mice make fewer entries through the CognitionWallTM in comparison to Chow-fed mice.
