n = 6–7 mice/group. A- Blood insulin evolution measured in non fasting mice, B- Blood insulin evolution measured in fasting mice, C- Blood glycemia evolution measured in fasting mice, D-E- Oral Glucose Tolerance test performed at 15 weeks of age: Glycemia measured after oral glucose tolerance administration (D), representation of delta glycemia level (compared to glycemia measured at T0) (E), F-G- Insulin sentitivity test: Glycemia measured after IP insulin administration (F), representation of delta glycemia level (compared to glycemia measured at T0) (G).
