Evaluate prebiotics using the high fat diet-fed mouse model

Muscle Adipose tissue Liver Macrophage

A dedicated nutritional animal model to demonstrate that your prebiotics impact metabolic parameters in adapted animal models i.e. early (4 weeks high fat feeding with glucose intolerance and impaired glucose-stimulated insulin secretion) or established (14 weeks high fat feeding with insulin resistance)

Key Benefits

► Validate a beneficial effects of your prebiotics on :

  • body weight and adipose tissue weight gain,
  • glucose intolerance and insulin resistance,
  • hepatic insulin signalling,
  • inflammation.

Dedicated nutritional animal model to demonstrate that your compound improves both early (4 weeks high fat diet) or established (14 weeks high fat diet) diabetes.

Animal Model

  • Background Strain: C57Bl6/J mouse
  • Gender/Weight: Male
  • Diet: High Fat Diet
  • Time on diet: 4 weeks (impaired insulin secretion) or 14 weeks (impaired insulin action)

Scientific and pharmacological relevance

Mouse fed a control (chow-ctrl) or high fat diet (HF-ctrl) or high fat diet + fermentable diatary fiber oligofructose (HF- OFS) for 4 weeks (impaired insulin secretion) or 14 weeks (impaired insulin action).

  • Oligofructose decreases plasma glucose and increases plasma insulin levels (both fasted and fed conditions) in mice fed a 4-week high fat diet.
  • Oligofructose lowers body weight gain, epididymal fat pads and total energy intake in mice fed a 4-week high fat diet.

  • Oligofructose reduces glucose intolerance in diabetic mice (high fat diet for 4 weeks).
  • Oligofructose improves insulin sensitivity in diabetic mice fed a high fat diet for 4 weeks (increased glucose infusion rate and blunted hepatic glucose production both measured during an hyperinsulinemic euglycemic clamp).

  • Oligofructose improves hepatic insulin signaling by increasing phosphorylation of IRS and akt in mice fed a 4-week high fat diet.
  • Oligofructose reduces hepatic inflammation by decreasing phosphorylation of NF-Kb in mice fed a 4-week high fat diet.

  • Oligofructose decreases hyperinsulinemia in mice fed a high fat diet over 14 weeks.
  • Oligofructose reduces total body weight gain, epididymal fat pads and energy intake in mice fed a high fat diet over 14 weeks.
