A role for insulin on L-arginine transport in fetal endothelial dysfunction in hyperglycaemia.


Endothelial cells are key in the regulation of vascular tone through the release of vasoactive molecules, including nitric oxide (NO). NO is a gas synthesized from the cationic amino acid L-arginine via the endothelial NO synthase (eNOS). The semi-essential amino acid L-arginine is a taken up by endothelial cells via systems y(+) and y(+)L in primary… (More)
