diet induced obesity (DIO) rat model

A nutritional rat model dedicated to obesity / insulin resistance studies

key benefits

  • To mimic gradual body weight gain, and especially visceral fat hypertrophy, as observed in western populations.
  • To select the best drug candidate in a very reproducible model, suitable for screening.
  • To test the efficacy of compounds in a model with sensitivity to all reference compounds tested close to clinical setting.

pharmacological validation

  • Positive reference compounds: sibutramin, pioglitazone, metformin
