Values are means ± s.e.m. (N≥7).
BW, brackish water control; FW, fresh water; NKCC2,Na+/K+/2Cl- cotransporters; CFTR, cystic fibrosis transmembrane conductance regulator; CA2, carbonic anhydrase 2;14-3-3a, signalling protein 14-3-3a.
Significant difference from 12 h BW group (P<0.05). There were no significant differences between FW and time-matched BW groups. qRT-PCR expression data are normalized to 12 h brackish water controls.
