Published: 22 February 2021
..., accumulating evidence suggests that endothelial cells are also active players in maintaining local metabolic homeostasis, in part, through regulating the supply of metabolic substrates, including lipids and glucose, to energy-demanding organs. Therefore, endothelial dysfunction, in terms of altered trans...

..., is rapidly deactivated by superoxide radicals. Endothelial cells were previously thought to be ‘glucose blind’ and thus unable to regulate GLUT1 expression in response to an HG challenge. However, it is now thought that endothelial GLUT1 expression can be down-regulated in response to hyperglycaemia...

...B. Leighton; A. Atkinson; M.P. Coghlan The monomeric enzyme GK (glucokinase) has a low affinity for glucose and, quantitatively, is largely expressed in the liver and pancreatic β-cells, playing a key ‘glucose sensing’ role to regulate hepatic glucose balance and insulin secretion. Mutations of GK...
