Aquaporin 4 is a ubiquitously expressed isoform in the dogfish (Squalus acanthias) shark [PDF]

open access: yes, 2012
Christopher P.Cutler is in receipt of a grant from the National Science Foundation, NSFIOS0844818.The dogfish ortholog of aquaporin 4 (AQP4) was amplified from cDNA using degenerate PCR followed by cloning and sequencing.

Bisacodyl overcomes morphine-induced constipation by decreasing colonic Aquaporin-3 and Aquaporin-4 expression [PDF]

open access: yesResearch Results in Pharmacology, 2022
Introduction: Morphine is an opioid prescribed to treat aches and pains. However, morphine often causes opioid-induced constipation (OIC). Aquaporin (AQP) transporters, especially AQP3 and AQP4, play an essential role in mediating constipation. Bisacodyl

Contrasting disease patterns in seropositive and seronegative neuromyelitis optica: A multicentre study of 175 patients [PDF]

open access: yes, 2012
BACKGROUND: The diagnostic and pathophysiological relevance of antibodies to aquaporin-4 (AQP4-Ab) in patients with neuromyelitis optica spectrum disorders (NMOSD) has been intensively studied. However, little is known so far about the clinical impact of

Structure determination of membrane-located complexes: Aquaporin 8 and YscC secretin [PDF]

open access: yes, 2011
A biological membrane is key to the life of a cell. In all living cells a biological membrane separates a inner life and an outer environment. Plasma membrane has many functions such as responding to external signals and transmitting them into the cell,

Barley plasma membrane intrinsic proteins (PIP aquaporins) as water and CO2 transporters [PDF]

open access: yes, 2008
We identified barley aquaporins and demonstrated that one, HvPIP2;1, transports water and CO2. Regarding water homeostasis in plants, regulations of aquaporin expression were observed in many plants under several environmental stresses. Under salt stress,

Genetic deletion of laminin isoforms β2 and γ3 induces a reduction in Kir4.1 and aquaporin-4 expression and function in the retina. [PDF]

open access: yesPLoS ONE, 2011
Glial cells such as retinal Müller glial cells are involved in potassium ion and water homeostasis of the neural tissue. In these cells, inwardly rectifying potassium (Kir) channels and aquaporin-4 water channels play an important role in the process of ...

Expression and localization of Aquaporin 1a in the sea-bass (Dicentrarchus labrax) during ontogeny [PDF]

open access: yes, 2011
The successful establishment of a species in a given habitat depends on the ability of each of its developing stages to adapt to the environment. In order to understand this process we have studied the adaptation of a euryhaline fish, the sea-bass ...

Aquaporin-4 expression in the human choroid plexus [PDF]

open access: yesCellular and Molecular Life Sciences, 2021
Abstract The choroid plexus (CP) consists of specialized ependymal cells and underlying blood vessels and stroma producing the bulk of the cerebrospinal fluid (CSF). CP epithelial cells are considered the site of the internal blood-cerebrospinal fluid barrier, show epithelial characteristics (basal lamina, tight junctions), and ...

Aquaporin 4 and its Relationship with Brain Astrocytomas – Literature Review

open access: yesBrazilian Neurosurgery, 2023
Background Aquaporins (AQPs) are a family of membrane proteins that regulate the osmotic permeability of the plasma membrane. There are described in the literature a total of 13 types of Aquaporins in mammals, each with different places of expression. In
