Bucladesine 163-169 aquaporin 2 Rattus norvegicus 94-99 12388395-3 2003 In the presence of the cAMP analog dibutyryl cAMP (DBcAMP, 500 microM), NaCl and sorbitol, but not urea, evoked a robust increase of AQP2 expression in IMCD cells, with NaCl being far more potent than sorbitol. Bucladesine 51-57 aquaporin 2 Rattus norvegicus 133-137
