Both Ocln and Ocln-a localized in the nephron, the epidermis and the luminal side of the gut. In branchial tissue, Tric...

..., the mechanisms with which this is achieved are likely to be different. Abrupt exposure to elevated salinity would require a rapid response that could be achieved with localized release of AST at the rectal epithelium, resulting in a rapid reduction in NKA and VA activity ( Fig. 6 ) and subsequent rapid reduction...

... tissue barriers that interface directly with surrounding water, but these organs generally function differently in osmoregulation. Therefore, roles for gill and skin claudin-6, -10d and -10e in the osmoregulatory strategies of T. nigroviridis were investigated. In the gill epithelium, claudin-6, -10d...

During all treatments, perfusion pressures showed no treatment-dependent effects, indicating that the observed changes in fluxes were due to specific effects of the treatment on the epithelium and not due to some indirect effect on perfusion pattern within the gill...

The energy to drive this transport has been proposed to come from the inwardly...
