mRNA expression levels for multiple acid/base transporters in the different segments of NBCe1 KO and WT mucosa at day 13–16 days of birth. a–c mRNA expression levels for acid/base transporters were calculated relative to the geometric mean of villin, cytokeratin 18, actin and RPS9. While the mRNA expression for the major transporters for electrolyte transport (NHE3, DRA, NKCC1, AE2, CFTR) was not different between WT and KO, other pHi regulators such as NHE1 and NBCn1 were significantly upregulated in the duodenum. *P < 0.05, n = 6
