Molecular mechanisms and drug development in aquaporin water channel diseases: water channel aquaporin-2 of kidney collecting duct cells.
Aquaporin-2 (AQP2) is one of the membrane water channel proteins expressed in principal cells of the kidney collecting ducts. In the basal state, AQP2 resides in the storage vesicles localized in the subapical cytoplasm. Upon stimulation with vasopressin, AQP2 is translocated to the apical plasma membrane by the exocytic fusion of the storage vesicles with the apical membrane. This translocatio...

متن کامل[Collecting duct renal cell carcinoma].
INTRODUCTION Bellini's renal cell collecting duct carcinoma is a rarely prevalent renal tumour, with low cancer-specific survival, although its rate of response to antiangiogenic therapies is unknown. OBJECTIVES We retrospectively revise a series of collecting duct tumours, with special emphasis on the indication of target therapies and on their results. MATERIALS AND METHODS Retrospective ...
متن کاملAquaporin-2 abundance in the renal collecting duct: new insights from cultured cell models.
The renal cortico-papillary osmotic gradient is generated by sodium reabsorption in the thick ascending limb. The antidiuretic hormone arginine vasopressin (AVP) increases collecting duct water permeability by enhancing aquaporin-2 (AQP2) water channel insertion in the apical membrane of principal cells, allowing water to passively flow along the osmotic gradient from the tubule lumen to the in...
متن کاملFourfold reduction of water permeability in inner medullary collecting duct of aquaporin-4 knockout mice.
Aquaporin (AQP)-3 and AQP4 water channels are expressed at the basolateral membrane of mammalian collecting duct epithelium. To determine the contribution of AQP4 to water permeability in the initial inner medullary collecting duct (IMCD), osmotic water permeability ( P f) was compared in isolated perfused IMCD segments from wild-type and AQP4 knockout mice. The AQP4 knockout mice were previous...
