... and the direction of Cl − movement through CFTR. In the rat intestine, stimulation of HCO 3 − secretion by SLC26 transporters also stimulates Cl − absorption by CFTR ( Ko et al., 2004 ); conversely, in the Gulf toadfish intestine, inhibition of HCO 3 − secretion correlates with stimulated Cl − secretion...

.../ Summary: Nitric oxide contributes to the regulation of ion transport in fish predominantly through the sGC/cGMP pathway and S -nitrosation of transport proteins may be an additional mechanism. NO Cl − secretion Mummichog Epithelial ion transport sGC/cGMP pathway The gasotransmitter...

...Mario Díaz; Antonio Lorenzo; Tomás Gómez; Pilar Badía; Ana Bolaños ABSTRACT Addition of BaCl 2 to the solution bathing colons of normal lizards did not alter the absorptive Na + flux, but did reverse the net absorption of Cl − to become net secretion. Cl − secretion resulted from an increase in its...
