Defective glycerol metabolism in aquaporin 9 (AQP9) knockout mice
(National Academy of Sciences, 2007-02-27)
Aquaporin-9 (AQP9) is an aquaglyceroporin membrane channel shown biophysically to conduct water, glycerol, and other small solutes. Because the physiological role/s of AQP9 remain undefined and the expression sites of AQP9 ...
Aquaporin-6: An intracellular vesicle water channel protein in renal epithelia
(National Academy of Sciences, 1999-05-01)
All characterized mammalian aquaporins (AQPs) are localized to plasma membranes where they function chiefly to mediate water transport across cells. Here we show that AQP6 is localized exclusively in intracellular membranes ...
Decreased pulmonary vascular permeability in aquaporin-1-null humans
(National Academy of Sciences, 2002-01-22)
The molecular determinants of water permeability in the human lung are incompletely defined. Aquaporins (AQP) are water-specific membrane channel proteins. AQP1 is present in endothelial cells in the lung, including those ...
Direct immunogold labeling of aquaporin-4 in square arrays of astrocyte and ependymocyte plasma membranes in rat brain and spinal cord
(National Academy of Sciences, 1998-09-29)
Aquaporin (AQP) water channels are abundant in the brain and spinal cord, where AQP1 and AQP4 are believed to play major roles in water metabolism and osmoregulation. Immunocytochemical analysis of the brain recently ...
Aquaporins and the respiratory system: advice for a lung investigator
(American Society for Clinical Investigation, 2000-01-01)
Delayed onset of brain edema and mislocalization of aquaporin-4 in dystrophin-null transgenic mice
(National Academy of Sciences, 2002-10-01)
Cerebral water accumulation was studied during induction of brain edema in dystrophin-null transgenic mice (mdx-betageo) and control mice. Immunofluorescence and immunoelectron microscopic analyses of dystrophin-null brains ...
Concurrent expression of erythroid and renal aquaporin CHIP and appearance of water channel activity in perinatal rats
(American Society for Clinical Investigation, 1993-10)
Major phenotypic changes occur in red cell membranes during the perinatal period, but the underlying molecular explanations remain poorly defined. Aquaporin CHIP, the major erythroid and renal water channel, was studied ...
Aquaporin-4 water channel protein in the rat retina and optic nerve: polarized expression in Müller cells and fibrous astrocytes
(Society for Neuroscience, 1998-04-01)
The water permeability of cell membranes differs by orders of magnitude, and most of this variability reflects the differential expression of aquaporin water channels. We have recently found that the CNS contains a member ...
Functional requirement of aquaporin-5 in plasma membranes of sweat glands
(National Academy of Sciences, 2002-01-08)
The distribution and function of aquaporins (AQPs) have not previously been defined in sweat glands. In this study, AQP1, AQP3, and AQP5 mRNA were demonstrated in rat paw by reverse transcription (RT)-PCR, but AQP2 and ...
Distribution of the aquaporin CHIP in secretory and resorptive epithelia and capillary endothelia
(National Academy of Sciences, 1993-08-01)
The existence of water-selective channels has been postulated to explain the high water permeability of erythrocytes and certain epithelial cells. The aquaporin CHIP (channel-forming integral membrane protein of 28 kDa), ...
