More than twice that number (17, aqp0 to -16) have been identified in the genomes of different jawed vertebrates (Gnathostomata) (Finn et al.
The subsequent evolution of aqp0 channels in Gnathostomata suggests that this multi-functional class of aquaporin experienced purifying selection.
WGD or tandem duplication, which might be inferred from their linkage to aqp0 genes in the chromosomes of many vertebrates.
The pH sensitivity of Aqp0 channels in tetraploid and diploid teleosts.

aqp0, -1, and -9 all show RT-PCR amplification in gill tissue samples (Fig.
aqp0, -1, and -9 cDNAs all amplify from renal tissue samples using RT-PCR (Fig.
RT-PCR studies also show amplification of aqp0 and very low levels of aqp3 (Fig.
RT-PCR studies further show aqp0, -1, and -3 cDNA amplification from a combined sample from the esophagus and cardiac/fundic stomach.
AQP0 is found in the epididymis of the stallion but not in the rat, whereas AQP1 is found in the bat and rat myoid cells surrounding the epididymal tubules of the caput region and endothelial cells of the vascular channels throughout the epididymis, but is not found in the mouse.
However, it is still possible that other Aqp0 and -8 paralogs, such as Aqp0b and -8aa, the latter being phylogenetically closer to the tetrapod AQP8 than to Aqp8b (Cerda and Finn, 2010), are present in seabream somatic cells.
