Nevertheless, in the AQPs involved in [Si(OH).sub.4], permeation of the glycine (AQP10) or phenylalanine (AQP7 or AQP9) of animals was present (Garneau et al., 2015).
In models that were developed based on these results, the water flows through AQP9 in the cell where it creates an increased pressure between the cell membrane and the cytoskeleton.
Three members of the aquaporin family, AQP3, AQP7, and AQP9, allow efficient diffusion of glycerol, in addition to water.
AQP9. Identificada en hepatocitos, celulas en las cuales parece cumplir su principal papel.
Cloning and functional expression of a new aquaporin (AQP9) abundantly expressed in the peripheral leukocytes permeable to water and urea, but not to glycerol.
Como os ERb estao amplamente distribuidos nos ductulos eferentes, o objetivo do presente trabalho foi investigar os efeitos de 3bdiol sobre a expressao de proteinas importantes para a manutencao da morfofisiologia deste segmento, incluindo AR e aquaporina AQP9. Foi realizada castracao cirurgica e castracao quimica com EDS (etanodimetanosulfonado), citotoxico para celulas de Leydig, em ratos Wistar adultos, seguida de reposicao com estradiol (400mg), DHT (5mg) e 3b-diol (3mg).
Strangely, AQP9 is also capable of transporting As[(OH).sub.3].
They are of the aquaglyceroporin type and show 40%-45% protein sequence identity to mammalian AQP3 and AQP9 (Uzcategui et al., 2004).
We have previously shown that aquaglyceroporin channels, including Escherichia coli GlpF, Saccharorayces cerevisiae Fps1p, AQP7, and AQP9 from rat and human, conduct trivalent inorganic arsenic [As(III)] as arsenic trioxide, the protonated form of arsenite.
It was described as an ortholog of Aqp9 based on a marginally higher level of amino acid homology to human AQP9 compared to its homology to other human AQP aquaglyceroporins (AQP3, -7, -10; Cutler, 2006b).
The Leydig cells of most mammals studied, except the bat and dog, also express the aquaglyceroporin AQP9, suggesting that this channel could also allow the passage of solutes across these cells.
