Vascular endothelial growth factor B improves impaired glucose tolerance through insulin-mediated inhibition of glucagon secretion

Figure 6 Vascular endothelial growth factor B regulates the content of Ca²⁺ and insulin via combining with vascular endothelial growth factor receptor 1. A: The protein expression of vascular endothelial growth factor B (VEGFB); B: The protein expression of VEGFB/β-actin; C: The protein expression of VEGF receptor 1/β-actin; D and E: The content of Ca²⁺ with 2.8 mmol/L and 16.7 mmol/L glucose; F and G: The content of insulin with 2.8 mmol/L and 16.7 mmol/L glucose. ^aP < 0.05 vs standard diet. ^bP < 0.05 vs high-fat diet-WT; ^cP < 0.05 vs Con. HFD: High-fat diet; AAV: Adeno-associated virus; SD: Standard diet.
