AQPs represent a family of ubiquitous membrane channels that regulate osmotically water flux in various tissues and sometimes the transport of small solutes, including glycerol. Here, we have presented a broad range of evidence demonstrating that these proteins have a role in cell proliferation by various different mechanisms, namely, by allowing fast cell volume regulation during cell division; by affecting progression of cell cycle and helping maintain the balance between proliferation and apoptosis, and by crosstalk with other cell membrane proteins or transcription factors that, in turn, modulate progression of the cell cycle or regulate biosynthesis pathways of cell structural components. Aquaporins, also called water channels, are channel proteins from a larger family of major intrinsic proteins that form pores in the membrane of biological cells, mainly facilitating transport of water between cells. Delgado-Bermúdez A, Noto F, Bonilla-Correal S, Garcia-Bonavila E, Catalán J, Papas M, Bonet S, Miró J, Yeste M. Biology (Basel). Kidneys contain two types of nephrons, each located in different parts of the renal cortex: cortical nephrons and juxtamedullary nephrons. There are at least 11 homologous aquaporins in mammals, at least 4 of which are expressed in the airways and lung. Aquaglyceroporins but not orthodox aquaporins are involved in the cryotolerance of pig spermatozoa. Explain the role of the nephron as the functional unit of the kidney. Biol Reprod. The molecular weight of the TIP subfamily members ranges from 25 to 28 kDa. The discovery of aquaporins, which are plasma-membrane-associated water channels, has greatly influenced the medical sciences.

Possible involvement of aquaporin-7 and -8 in rat testis development and spermatogenesis. aquaporins (AQPs); cell cycle; cell proliferation; gene expression; glycerol; hydrogen peroxide permeability; neurogenic niche. In the absence of E-cadherin, β-catenin will lose its anchor to the cell membrane and will translocate to the nucleus and then co-activates the transcription factor TCF/LEF, thus promoting expression of pro-proliferative genes as MMP19 and Cyclin D1, or anti-apoptotic genes such as COX2 and Survivin. This review is focused on the biology of these aquaporins with respect to airway and lung physiology. So far, thirteen aquaporins have been identified in humans. Epub 2013 Dec 13. 2020 Feb 12;11:46. doi: 10.3389/fgene.2020.00046. Using ejaculates from donors, sperm AQPs were identified by western blotting followed by the analysis of mRNA with RT-PCR. Zador Z, Bloch O, Yao X, Manley GT (2007) Aquaporins: role in FASEB J 19:76–78 cerebral edema and brain water balance. FOIA Med Sci (Paris). There is a considerable body of information about AQP structure from electron and x-ray crystallography (reviewed by Fujiyoshi et al., 2002),showing AQP monomers (∼30 kDa) containing six membrane-spanning helical domains surrounding a narrow aqueous pore. Aquaporins are expressed in the cell membrane and selectively permeable to water for water transport to the body. eCollection 2019. In order to directly compare the results of MD simulations with biochemical measurements of the conductivity of membrane water channels, in which osmotic pressure gradients are used to induce the flow of water across the membrane, we developed a new methodology for MD simulations. 2018 Nov 10;7(11):207. doi: 10.3390/cells7110207. Recent studies have focused on the assessment of fluid flux regulation in relation to the biological processes that maintain mesenchymal stem cell (MSC) physiology. Another important effect of NF-kβ activation would be the repression of E-cadherin. Sperm AQP7 and AQP8 in 39 infertile patients and 11 healthy donors were quantified by flow cytometry. So far, thirteen aquaporins have been identified in humans. Putting Channels under Pressure. Therefore, the involvement of AQPs in epithelial fluid transport is not unexpected. Aquaporins (AQPs) are integral membrane proteins and found in all living organisms from bacteria to human. Effect of AQP Inhibition on Boar Sperm Cryotolerance Depends on the Intrinsic Freezability of the Ejaculate. Yeung CH, Callies C, Rojek A, Nielsen S, Cooper TG. The structural basis of water permeation and proton exclusion in aquaporins. In the end, however, after discussing all these data that strongly support a role for AQPs in the cell proliferation process, it remains impossible to conclude that all these other functions attributed to AQPs occur completely independently of their water permeability, and there is a need for new experiments designed specifically to address this interesting issue. Clin Exp Pharmacol Physiol 37:403–409 in mice lacking choroid plexus water channel aquaporin-1. In-depth proteome analysis of more than 12,500 proteins in buffalo mammary epithelial cell line identifies protein signatures for active proliferation and lactation.

Unable to load your collection due to an error, Unable to load your delegates due to an error. 8600 Rockville Pike In conclusion, AQP7 and AQP8 were identified in human spermatozoa and could play a role in glycerol metabolism and water transport respectively. AQP8 and AQP9 can be blocked by HgCl 2 , which does not affect AQP7 as a result of its lack of the cysteine residue at the water pore which binds the mercuric ion in other aquaporins. The distribution of the mammalian aquaporins predicts their participation in a range of pathophysiological events. Aquaporins in spermatozoa and testicular germ cells: identification and potential role. Molecular Basis of Aquaporin-7 Permeability Regulation by pH.

The Role of Water Homeostasis in Muscle Function and Frailty: A Review. The intestine As early as 1930, it was shown that SW-acclimated fishes drink considerable amounts of SW to compensate for osmotic water primarily across the gill ( Smith et al., 1930 ). In animals, silicon is an abundant and differentially distributed trace element that is believed to play important biological functions. Aquaporins (AQPs) are integral membrane proteins that facilitate the transport of water across biological membranes along an osmotic gradient. We include clinical data on the correlation between four real-world, dietary aquaporin and five neurological tissue antibodies. Birth is a transition from an underwater life in the uterus to a terrestrial life in a milieu where supply of water is limited. See this image and copyright information in PMC.

Aquaporin 1 is a protein that in humans is encoded by the AQP1 gene.. AQP1 is a widely expressed water channel, whose physiological function has been most thoroughly characterized in the kidney.It is found in the basolateral and apical plasma membranes of the proximal tubules, the descending limb of the loop of Henle, and in the descending portion of the vasa recta. A unique set of aquaporins is expressed in each tissue, and each aquaporin has unique characteristics and performs unique functions. Tonoplast Intrinsic Proteins (TIP) are one of five subfamilies of aquaporins in higher plants. 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 of these proteins in numerous cellular processes seemingly unrelated, at least some of them in a direct way, to their canonical function of water permeation. Humans lacking AQP2, the vasopressin-regulated water channel, have a rare autosomal form of hereditary nephrogenic diabetes insipidus .

One would thus expect silicon concentrations in body fluids to be regulated by silicon transporters at the surface of many cell types. FEBS J. Using ejaculates from donors, sperm AQPs were identified by western blotting followed by the analysis of mRNA with RT-PCR. Aquaporins (AQPs) are a family of membrane water channel proteins that control osmotically-driven water transport across cell membranes. In the scheme it is shown that different cytokines among which TNFSF18 (in red, overexpressed) can activates the IKK complex via phosphorylation by a membrane receptor such as TNFR or others (IL6R, GP130, IFNγR) and by doing that will promote the dissociation of N-Fkβ from Ikβ.

Aquaporin-Mediated Water and Hydrogen Peroxide Transport Is Involved in Normal Human Spermatozoa Functioning. The absence of sperm AQP9 was further suggested by the ineffectiveness of its inhibitor phloretin in blocking quinine-induced swelling, but HgCl(2,) which inhibits AQP8, was effective. The analysis of propidium iodide-derived cell cycle profiles show a larger percentage of cells in the S and G2/M phases of PC12-AQP1 and PC12-AQP3 cells compare to wild type cells, indicative of a larger proliferative capacity when cells express AQPs.
