| Title | Interactions between angiotensin II and arginine vasopressin in water homeostasis. | | Author(s) | Schrier RW | | Institution | Department of Medicine, University of Colorado Denver, 12700 East 19th Avenue C281, Aurora, Colorado, USA. | | Source | Kidney Int 2009 Jul; 76(2):137-9. | | Abstract | Mice deficient in the angiotensin II type 1a (AT(1a)) receptor demonstrate a vasopressin-resistant nephrogenic diabetes insipidus. These knockout mice exhibit a threefold increase in 24-h urine excretion. Neither 2 weeks of exogenous vasopressin nor 5 days of fluid restriction reversed this polyuric state. This nephrogenic diabetes insipidus was associated with reductions in adenylyl cyclase protein and in the phosphorylated mitogen-activated protein kinase extracellular signal-regulated kinase 1/2. The results support an important interaction between vasopressin and angiotensin II in maximal urinary concentration. | | Language | eng | | Pub Type(s) | Comment
