CHARACTERIZATION AND FUNCTIONALITY OF RECOMBINANT AQUAPORINS FROM MOZAMBIQUE TILAPIA
… Mozambique tilapia (Oreochromis mossambicus) aquaporins are potential candidates for the biomimetic membrane due to the ability of this tilapia to survive and adapt in a range of salinities. To date, the functionality of Mozambique tilapia aquaporins still remains unknown except for …

Salinity Responsiveness of Aquaporins in Osmoregulatory Organs of Larval Mosquito Aedes Aegypti
… membranes through transmembrane proteins named aquaporins (AQPs) and A. aegypti possess six AQP homologues (AaAQP). This is the first comprehensive study examining the expression of AQPs in A. aegypti and their response to changes in environmental salinity within the osmoregulatory organs. An …

Gating of water channels (aquaporins) in plants: effects of osmotic and oxidative stresses and the role of unstirred layers
… is accumulating evidence that water channels (aquaporins; AQPs) play an important role in plant water relations at the levels of cells, tissues, organs, and whole plants. AQPs facilitate the rapid, passive exchange of water across cell membranes. Most of the water permeability of plasma …

Zur Regulation und Expression von Aquaporinen unter Berücksichtigung des pflanzlichen Wasserhaushaltes
… und für Untersuchungen zur Beteiligung des Aquaporins PIP1b an Wassertransportvorgängen während der Stomaöffnung verwendet. Die Messungen der Transpirationsraten von PIP1b-Antisense-Pflanzen ergaben keine Hinweise auf Veränderungen des zeitlichen Verlaufs der Stomaöffnung. Die …

Biomimetic membranes as new materials for applications in envrionmental engineering and biology
Biological water channel proteins, called aquaporins, provide selective and rapid transport of water across cell membranes. They utilize an elegant mechanism distinct from and more efficient than that used in commercial solute separation polymeric membranes such as Reverse Osmosis (RO) membranes. …

Molecular mechanism of Trypanosoma brucei Aquaglyceroporin 2
… larger than any other known permeants for aquaporins and pentamidine is double positively charged under physiological conditions. The molecular mechanism of the TbAQP2-linked drug uptake in trypanosomes is controversial. Suggested mechanisms include transport through the unconventional …

Investigating Protein Properties via Microfluidic Techniques
… 4, the interactions between a membrane protein (aquaporins) and a small regulator protein (calmodulin) are investigated by detecting the changes of their electrophoretic mobility and diffusivity in microfluidic devices. Then the effective charges of aquaporin0 and its complex with calmodulin are …

Aquaporin 3 Water Channel Protein Gene Expression in Squalis Acanthias Dogfish Shark
Aquaporins are a family of membrane proteins that provide channels for the rapid movement of water molecules and some small solutes across the cellular membrane. Since the discovery of the first water channel protein, hundreds of homologous proteins have been found in all forms of life and much has …

Molekulare Charakterisierung der Reaktion von Lycopersicon esculentum auf den phanerogamen Parasiten Cuscuta reflexa
… Xyloglucanendotransglycosylase LeEXT1 sowie des Aquaporins LeAqp2 untersucht. Trotz auxinregulierter Transkription nach Cuscuta-Befall zeigte die auxininsensitive Tomatenmutante diageotropica im Vergleich zum Wildtyp keine veränderte Kompatibilität.

Pharmacologically impeding glioblastoma tumour motility through simultaneous inhibition of aquaporin-1 and ion channels
… pathways that control cellular motility include aquaporins and ion channels. These protein classes could therefore be prime candidates as pharmacological targets to restrain cell motility in glioblastoma. Identifying optimal combinations of inhibitory agents to use against selected channel …

Microscopic description of gas permeation and delivery pathways in biological macromolecules
… structural insights into the selectivity of aquaporins for NH3, CO2 and glycerol. Aquaporins, widely known as membrane-facilitated water channels, also facilitate the permeation of gases and other molecules such as glycerol but with different degrees in selectivity. The recent crystal …

Water permeability of plant cells measured by pressure probes: effects of light and turgor, and the role of unstirred layers
… caused by an oxidative gating of water channels (aquaporins; AQPs), as indicated by the fact that (i) application of reactive oxygen species (ROS) resulted in responses similar to those of HL and (ii) HL effects could be reversed in the presence of the antioxidant glutathione. For the first time, …

Pharmacological Modulation of Cancer Migration and Invasion Through Targeting AQP1 Ion and Water Channel Activity
… and metastasis in these cancer types. Other aquaporins with water channel function are not able to substitute for aquaporin-1 in facilitating cell migration. There is a gap in knowledge regarding the properties of aquaporin-1 that permit its migration-enhancing effect, but both the ion and …

Aquaglyceroporin Expression and Regulation in Erythrocytes From Freeze Tolerant Cope’s Gray Treefrog, <i>Hyla Chrysoscelis</i>
… as a cryoprotectant during cold acclimation. Aquaporins, members of the major intrinsic protein (MIP) family of transmembrane water pores, may play an important role in the mechanism of freeze tolerance by mediating glycerol and water transport across cell membranes. Thus, we hypothesize that …

Identification of growth-related tonoplast proteins in Arabidopsis thaliana
… and by controlling the water channels, the aquaporins. Together with the control of cell wall relaxation, vacuolar osmotic pressure regulation is thought to play an important role in cell expansion, directly by providing cell volume and indirectly by providing ion and pH homestasis for the …

Mechanism and energetics of membrane transporters and channels
… as the third family of gas channels along with aquaporins (water channels), and Rh-associated glycoprotein (RhAG) (ammonia channels). The other membrane channel system that we investigated is an aquaporin. Aqua- porins are ubiquitous integral membrane channels that maintain water homeostasis of …
