Respiratory aquaporins in lung inflammation: the night is young
(American Thoracic Society, 2000-01)
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), ...
Proteomic analysis of lithium-induced nephrogenic diabetes insipidus: Mechanisms for aquaporin 2 down-regulation and cellular proliferation
(National Academy of Sciences, 2008-03-04)
Lithium is a commonly prescribed mood-stabilizing drug. However, chronic treatment with lithium induces numerous kidney-related side effects, such as dramatically reduced aquaporin 2 (AQP2) abundance, altered renal function, ...
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-1 Water Channel Expression in Human Kidney
(American Society for Nephrology, 1997-01)
The pattern of aquaporin-1 water channel protein (AQP1) expression in the human kidney was analyzed by immunocytochemistry using semi-thin and optimized high-resolution immunoelectron microscopy based on freeze-substituted ...
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 ...
Aquaporin-1 water channel protein in lung: ontogeny, steroid-induced expression, and distribution in rat
(American Society for Clinical Investigation, 1996-05-15)
At birth water is rapidly reabsorbed from the distal lung in preparation for alveolar gas exchange. To investigate a potential role for the AQP1 water channel in development, lung membranes from fetal and perinatal rats ...
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 ...
Aquaporin-11: a channel protein lacking apparent transport function expressed in brain
(BioMed Central, 2006-05)
BACKGROUND: The aquaporins are a family of integral membrane proteins composed of two subfamilies: the orthodox aquaporins, which transport only water, and the aquaglyceroporins, which transport glycerol, urea, or other ...
