Knockdown of VEGF-B improves HFD-induced insulin resistance by enhancing glucose uptake in vascular endothelial cells via the PI3K/Akt pathway.

Vascular endothelial growth factor B (VEGF-B) has been suggested to play a crucial role in regulating whole-body glucose homeostasis. However, the involved mechanisms are not fully understood. This study aimed to elucidate the regulatory effects and mechanisms of VEGF-B on glucose uptake in skeletal muscle, focusing on glucose uptake by skeletal muscle cells and vascular endothelial cells.
