Rat Adrenal Chromaffin Cells Are Neonatal CO2 Sensors
(2005)
We studied the participation of adrenal medulla (AM) chromaffin cells in hypercapnic chemotransduction. Using amperometric recordings, we measured catecholamine (CAT) secretion from cells inAMslices of neonatal and adult ...

Expression Pattern of Aquaporin 1 and Aquaporin 3 in Melanocytic and Nonmelanocytic Skin Tumors
(American journal of clinical pathology, 2019)
Objectives: Study of aquaporin 1 (AQP1) and aquaporin 3 (AQP3) expression to understand its potential role in the pathophysiology of skin cancer. Methods: Analysis of AQP1 and AQP3 expression by immunohistochemistry ...

Combined effects of aquaporin-4 and hypoxia produce age-related hydrocephalus
(Elsevier, 2018)
Aquaporin-4, present in ependymal cells, in glia limiting and abundantly in pericapillary astrocyte foot pro cesses, and aquaporin-1, expressed in choroid plexus epithelial cells, play an important role in cerebrospinal fluid ...

Cellular distribution of brain aquaporins and their contribution to cerebrospinal fluid homeostasis and hydrocephalus
(MDPI, 2022)
Brain aquaporins facilitate the movement of water between the four water compartments: blood, cerebrospinal fluid, interstitial fluid, and intracellular fluid. This work analyzes the expression of the four most abundant ...

Trophic restoration of the nigrostriatal dopaminergic pathway in long-term carotid body-grafted parkinsonian rats
(2003)
We studied the mechanisms underlying long-term functional recovery of hemiparkinsonian rats grafted intrastriatally with carotid body (CB) cell aggregates. Amelioration of their motor syndrome is a result of the trophic ...

Role of aquaporins in cell proliferation: What else beyond water permeability?
(Taylor & Francis Open Access, 2016-02-21)
In addition to the extensive data demonstrating the importance of mammalian AQPs for the movement of water and some small solutes across the cell membrane, there is now a growing body of evidence indicating the involvement ...

Overexpression of AQP3 Modifies the Cell Cycle and the Proliferation Rate of Mammalian Cells in Culture
(PUBLIC LIBRARY SCIENCE, 2015-09-14)
Abnormal AQP3 overexpression in tumor cells of different origins has been reported and a role for this enhanced AQP3 expression in cell proliferation and tumor processess has been indicated. To further understand the role ...

Aquaporin-4 Mediates Permanent Brain Alterations in a Mouse Model of Hypoxia-Aged Hydrocephalus
(MDPI, 2021-09-09)
Aquaporin-4 (AQP4) is the principal water channel in the brain being expressed in astrocytes and ependymal cells. AQP4 plays an important role in cerebrospinal fluid (CSF) homeostasis, and alterations in its expression ...

Targeting Aquaporin Function: Potent Inhibition of Aquaglyceroporin-3 by a Gold-Based Compound
(Public Library of Science, 2012-05-18)
Aquaporins (AQPs) are membrane channels that conduct water and small solutes such as glycerol and are involved in many physiological functions. Aquaporin-based modulator drugs are predicted to be of broad potential utility ...

Evaluation of aquaporins in the cerebrospinal fluid in patients with idiopathic normal pressure hydrocephalus
(PLOS, 2021)
Brain aquaporin 1 (AQP1) and AQP4 are involved in cerebrospinal fluid (CSF) homeostasis and might participate in the origin of hydrocephalus. Studies have shown alterations of perivascular AQP4 expression in idiopathic ...
