| Sumario: | Abstract: Cystic fibrosis (CF) is the most frequent autosomal recessive disease and is
caused by mutations in the cystic fibrosis transmembrane conductance regulator
(CFTR) gene. Since the discovery of the deletion in the phenylalanine 508 site
(ΔF508) of the CFTR gene, the study of its function as chloride channel occupied
most investigations. Now, we know that CFTR is also involved in the GSH
and HCO3 − transport, and its function could regulate the mitochondrial function
and ROS production. In this way, the notion of the CFTR as a simple chloride
channel has begun to change toward a more complex function as molecular hub
that integrates different cellular signals. There is a growing body of evidence that
shows mitochondrial dysfunctions and increased oxidative stress in CF. Here, we
review the mitochondrial defects induced by the altered function of the CFTR in
CF, focusing on oxidative stress and inflammation as targets for therapy. |
