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 ...
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 ...
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), ...
Targeted disruption of the Cl−/HCO3− exchanger Ae2 results in osteopetrosis in mice
(National Academy of Sciences, 2009-02-03)
Osteoclasts are multinucleated bone-resorbing cells responsible for constant remodeling of bone tissue and for maintaining calcium homeostasis. The osteoclast creates an enclosed space, a lacuna, between their ruffled ...
Aquaporins and the respiratory system: advice for a lung investigator
(American Society for Clinical Investigation, 2000-01-01)
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 ...
Aquaporins in complex tissues. I. Developmental patterns in respiratory and glandular tissues of rat
(American Physological Society, 1997-11)
Developmental expression of aquaporin water transport proteins is not well understood in respiratory tract or secretory glands; here we define aquaporin protein ontogeny in rat. Expression of aquaporin-3 (AQP3), AQP4, and ...
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 ...
Aquaporin 9 is the major pathway for glycerol uptake by mouse erythrocytes, with implications for malarial virulence
(National Academy of Sciences, 2007-07-24)
Human and rodent erythrocytes are known to be highly permeable to glycerol. Aquaglyceroporin aquaporin (AQP)3 is the major glycerol channel in human and rat erythrocytes. However, AQP3 expression has not been observed in ...
