Aquaporin-6: An intracellular vesicle water channel protein in renal epithelia [PDF]

open access: yesProceedings of the National Academy of Sciences, 1999
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 in renal epithelia. By using a polyclonal antibody to the C terminus of AQP6, immunoblots revealed a major 30-kDa band in ...

Correlation between serum AQP-4 antibody, inflammatory cytokines and recurrence of neuromyelitis optica in patients with chronic insomnia

open access: yesZhongguo linchuang yanjiu, 2022
Objective To investigate the levels of serum aquaporin 4(AQP-4) antibodies and cytoinflammatory factors in patients with neuromyelitis optica(NMO) complicated with chronic insomnia and their correlation with the recurrence of NMO. Methods A total of 103

A comparison of aquaporin expression in mosquito larvae (Aedes aegypti) that develop in hypo-osmotic freshwater and iso-osmotic brackish water.

open access: yesPLoS ONE, 2020
The mosquito Aedes aegypti vectors the arboviral diseases yellow fever, dengue, Zika and chikungunya. Larvae are usually found developing in freshwater; however, more recently they have been increasingly found in brackish water, potential habitats which ...

Stem aquaporins and surfactant-related genes are differentially expressed in two Eucalyptus species in response to water stress

open access: yesPlant Stress, 2021
The regulation of water column tension in the xylem is essential to avoid embolism formation. Plants can actively reduce the hydraulic resistance in the xylem by moving water from the neighbourhood living cell, via aquaporins.

Incipient balancing selection through adaptive loss of aquaporins in natural Saccharomyces cerevisiae populations. [PDF]

open access: yesPLoS Genetics, 2010
A major goal in evolutionary biology is to understand how adaptive evolution has influenced natural variation, but identifying loci subject to positive selection has been a challenge.

Distinct serum and cerebrospinal fluid cytokine and chemokine profiles in autoantibody-associated demyelinating diseases

open access: yesMultiple Sclerosis Journal - Experimental, Translational and Clinical, 2019
Background Demyelinating diseases of the central nervous system associated with autoantibodies against aquaporin-4 and myelin-oligodendrocyte-glycoprotein are mediated by different immunopathological mechanisms compared to multiple sclerosis.

Expression Analysis of Sugarcane Aquaporin Genes under Water Deficit

open access: yesJournal of Nucleic Acids, 2013
The present work is a pioneer study specifically addressing the aquaporin transcripts in sugarcane transcriptomes. Representatives of the four aquaporin subfamilies (PIP, TIP, SIP, and NIP), already described for higher plants, were identified. Forty-two

Aquaporin-6 is expressed along the rat gastrointestinal tract and upregulated by feeding in the small intestine [PDF]

open access: yesBMC Physiology, 2009
Several aquaporins (a family of integral membrane proteins) have been recently identified in the mammalian gastrointestinal tract, and their involvement in the movement of fluid and small solutes has been suggested. In this direction we investigated, in some regions of the rat gastrointestinal tract, the presence and localization of aquaporin-6, given ...

Adenylate Cyclase 6 Determines cAMP Formation and Aquaporin-2 Phosphorylation and Trafficking in Inner Medulla [PDF]

open access: yesJournal of the American Society of Nephrology, 2010
Arginine vasopressin (AVP) enhances water reabsorption in the renal collecting duct by vasopressin V₂ receptor (V₂R)-mediated activation of adenylyl cyclase (AC), cAMP-promoted phosphorylation of aquaporin-2 (AQP2), and increased abundance of AQP2 on the apical membrane.

Conversion of aquaporin 6 from an anion channel to a water-selective channel by a single amino acid substitution [PDF]

open access: yesProceedings of the National Academy of Sciences, 2005
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 between closed and open status.
