Detecting aquaporin function and regulation

Frontiers in Chemistry, 2016
Water is the major component of cells and tissues throughout all forms of life. Fluxes of water and solutes through cell membranes and epithelia are essential for osmoregulation and energy homeostasis. Aquaporins are membrane channels expressed in almost

Aquaporins in Pacific White Shrimp (Litopenaeus vannamei): Molecular Characterization, Expression Patterns, and Transcriptome Analysis in Response to Salinity Stress

Frontiers in Marine Science, 2022
Aquaporins (AQPs) are integral membrane proteins that facilitate the transport of water and small solutes across cell membranes. These proteins are vital for maintaining water homeostasis in living organisms.

An Atypical Aquaporin 1 Derived From Paramecium multimicronucleatum Functions as a Multifunctional Channel That Permeates Water, Glycerol, and Urea

Journal of Eukaryotic Microbiology, Volume 73, Issue 4, July/August 2026.
ABSTRACT Although it had been reported that the translation product of the functional aquaporin gene, aqp1, is localized to the contractile vacuole complex of Paramecium multimicronucleatum, the molecules that pass through this channel protein had not been identified. In the present study, we introduced and expressed this protein in Xenopus oocytes and

Reviving the Skin From Within: Mechanistic Insights Into a Well‐Tolerated Dermal Filler—CPM‐HA20G

Journal of Cosmetic Dermatology, Volume 25, Issue 6, June 2026.
ABSTRACT Background Dermal fillers composed of hyaluronic acid (HA) combined with glycerol have been clinically shown to enhance skin hydration and quality; the precise mechanisms underlying their efficacy have yet to be fully elucidated. Aims Investigation of the dual hydration mechanisms, cell protection and tolerability, and tissue compatibility of ...

Aquaporins with anion/monocarboxylate permeability: mechanisms, relevance for pathogen-host interactions

Frontiers in Pharmacology, 2014
Classically, aquaporins are divided based on pore selectivity into water specific, orthodox aquaporins and solute-facilitating aquaglyceroporins, which conduct e.g. glycerol and urea.

Phosphate Transporters Mediate the Uptake of Monothioarsenate

Plant, Cell &Environment, Volume 49, Issue 5, Page 2628-2638, May 2026.
ABSTRACT Arsenic (As) is one of the most problematic environmental toxins. Exposure to As, predominantly via drinking water and the intake of food, represents a major human health threat. Various species of As exist in the environment, among them organic and inorganic thioarsenates.

Aquaglyceroporins and Metalloid Transport: Implications in Human Diseases [PDF]

, 2008
Aquaglyceroporin (AQP) channels facilitate the diffusion of a wide range of neutral solutes, including water, glycerol, and other small uncharged solutes. More recently, AQPs have been shown to allow the passage of trivalent arsenic and antimony compounds. Arsenic and antimony are metalloid elements. At physiological pH, the trivalent metalloids behave

Energetics of glycerol conduction through aquaglyceroporin GlpF [PDF]

Proceedings of the National Academy of Sciences, 2002
Aquaglyceroporin GlpF selectively conducts water and linear polyalcohols, such as glycerol, across the inner membrane of Escherichia coli . We report steered molecular dynamics simulations of glycerol conduction through GlpF, in which external forces accelerate the transchannel conduction in ...

Endo-Porter–mediated delivery of phosphorodiamidate morpholino oligos (PMOs) in erythrocyte suspension cultures from Cope's gray treefrog Hyla chrysoscelis

BioTechniques, 2011
Cope's gray treefrog, Hyla chrysoscelis, is a freeze-tolerant anuran that accumulates cryoprotective glycerol during cold acclimation. H. chrysoscelis erythrocytes express the aquaglyceroporin HC-3, which facilitates transmembrane glycerol and water ...

Industrial strategies to minimize glycerol formation in ethanol fermentation by conventional Saccharomyces cerevisiae

Biofuels, Bioproducts and Biorefining, Volume 20, Issue 2, Page 1006-1020, March/April 2026.
Abstract Industrial ethanol production faces the challenge of balancing metabolic efficiency with the minimization of byproducts such as glycerol, whose formation is intensified by osmotic, thermal, oxidative, and nutritional stresses. In the literature, two main approaches stand out for modulating its synthesis: the use of genetically modified strains
