Insulin induced hypoglycemia stimulates corticotropin releasing factor and arginine vasopressin secretion into hypophysial portal blood of conscious, unrestrained rams
... Insulin-induced hypoglycemia (IIH) is a strong stimulator of pituitary ACTH secretion. The mechanisms by which IIH activates the corticotrophs are still controversial. Indeed, in rats the variations of ...

Arginine vasopressin stimulates human mesangial cell production of endothelin
... Endothelin (ET) is a vasoactive peptide produced by both endothelial epithelial cells with documented mitogenic action on mesangial cells. The present studies were designed to test the hypothesis that ET is also produced ...
