Aquaporin water channels: atomic structure molecular dynamics meet clinical medicine
(American Society for Clinical Investigation, 2002-06-01)
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 ...
Altered ubiquitination and stability of aquaporin-1 in hypertonic stress
(National Academy of Sciences, 2001-02-27)
Aquaporin-1 (AQP1) water channel protein expression is increased by hypertonic stress. The contribution of changes in protein stability to hypertonic induction of AQP1 have not been described. Incubation of BALB/c fibroblasts ...
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 ...
Syntrophin-dependent expression and localization of Aquaporin-4 water channel protein
(National Academy of Sciences, 2001-11-20)
The Aquaporin-4 (AQP4) water channel contributes to brain water homeostasis in perivascular astrocyte endfeet where it is concentrated. We postulated that AQP4 is tethered at this site by binding of the AQP4 C terminus to ...
Water and ion permeation of aquaporin-1 in planar lipid bilayers. Major differences in structural determinants and stoichiometry.
(American Society for Biochemistry and Molecular Biology, 2001-08-24)
The aquaporin-1 (AQP1) water channel protein is known to facilitate the rapid movement of water across cell membranes, but a proposed secondary role as an ion channel is still unsettled. Here we describe a method to ...
Defective cellular trafficking of lacrimal gland aquaporin-5 in Sjögren's syndrome
Dry eyes and dry mouth are clinical hallmarks of Sjögren's syndrome. We assessed the distribution of aquaporin-5 (AQP5) in lacrimal gland biopsy samples. Healthy controls and patients with Mikulicz's disease or non-Sjögren's ...
Aquaporin water channels [Nobel Lecture]
(Gesellschaft Deutscher Chemiker, 2004)
Temporary loss of perivascular aquaporin-4 in neocortex after transient middle cerebral artery occlusion in mice
(National Academy of Sciences, 2006-09-05)
The aquaporin-4 (AQP4) pool in the perivascular astrocyte membranes has been shown to be critically involved in the formation and dissolution of brain edema. Cerebral edema is a major cause of morbidity and mortality in ...
Conversion of aquaporin 6 from an anion channel to a water-selective channel by a single amino acid substitution
(National Academy of Sciences, 2005-02-08)
Aquaporin (AQP) 6 belongs to the aquaporin water channel family. Unlike other aquaporins, AQP6 functions not as a water channel but as an anion-selective channel. Single-channel analyses have shown AQP6 to flicker rapidly ...
