ydration of airways mucus plus the lowered alkalization of pancreatic juice in the course of CF are related to the loss of interaction among CFTR and the epithelial Na [http://www.medchemexpress.com/MLN1117.html INK-1117] channel or between CFTR as well as the Cl-/HCO3exchangers, respectively. Other dysfunctions could be more subtle. For instance, it had been extended believed that despite the wide expression of CFTR along the human nephron, there was no detectable CF renal phenotype. But later it was shown that the loss of interaction of CFTR with megalin could result in a defective receptor-mediated endocytosis inside the renal proximal tubule, thus an enhanced urinary transferrin loss for the duration of CF. In this nephron segment, CFTR is colocalized with all the sodium-phosphate co-transporter NPT2a, as it is in osteoblasts.
