..., compared with the ionic composition of the surrounding seawater. We pharmacologically investigated the role of Na + /H + exchangers (NHE) in intracellular pH regulation and midgut proton and sodium maintenance using the NHE inhibitor 5-( n -ethyl- n -isopropyl)amiloride (EIPA). Basolateral EIPA application...

... on NHE expression were investigated. The elevation of plasma cortisol using intraperitoneal implants caused a significant increase in NHE2 mRNA expression without affecting NHE3 mRNA or protein abundance. Thus, we suggest that NHE2 contributes to acid–base regulation during hypercapnia owing to its...
