1 In cells expressing wt-CFTR, ambroxol increased the Cl(-) conductance, but not the bicarbonate conductance of the CFTR channels. Ambroxol CF transmembrane conductance regulator Homo sapiens
2 CFBE cells were treated with 100 microM ambroxol for 2, 4 or 8 h. mRNA expression for CFTR and ENaC subunits was analysed by real-time polymerase chain reaction (RT-PCR); protein expression was measured by Western blot. Ambroxol CF transmembrane conductance regulator Homo sapiens
3 Ambroxol significantly stimulated Cl(-) efflux from CFBE cells (a sixfold increase after 8 h treatment), and enhanced the expression of the mRNA of CFTR and alpha-ENaC, and of the CFTR protein. Ambroxol CF transmembrane conductance regulator Homo sapiens
4 Ambroxol significantly stimulated Cl(-) efflux from CFBE cells (a sixfold increase after 8 h treatment), and enhanced the expression of the mRNA of CFTR and alpha-ENaC, and of the CFTR protein. Ambroxol CF transmembrane conductance regulator Homo sapiens
5 Upregulation of CFTR and enhanced Cl(-) efflux after ambroxol treatment should promote transepithelial ion and water transport, which may improve hydration of the mucus, and therefore be beneficial to CF-patients. Ambroxol CF transmembrane conductance regulator Homo sapiens
