Regulation of endogenous ENaC functional expression by CFTR and ΔF508-CFTR in airway epithelial cells.
The functional expression of the epithelial sodium channel (ENaC) appears elevated in cystic fibrosis (CF) airway epithelia, but the mechanism by which this occurs is not clear. We tested the hypothesis that the cystic fibrosis transmembrane conductance regulator (CFTR) alters the trafficking of endogenously expressed human ENaC in the CFBE41o⁻ model of CF bronchial epithelia. Functional expres...
متن کاملRegulation of cystic fibrosis transmembrane conductance regulator by microRNA-145, -223, and -494 is altered in ΔF508 cystic fibrosis airway epithelium.
Expression of the cystic fibrosis transmembrane conductance regulator (CFTR) is altered in individuals with the ΔF508 CFTR mutation. We previously reported differential expression of microRNA (miRNA) in CF airway epithelium; however, the role of miRNA in regulation of CFTR expression here remains unexplored. In this study, we investigated the role of upregulated miRNAs in CFTR regulation in viv...
متن کاملOrganelle redox of CF and CFTR-corrected airway epithelia.
In cystic fibrosis reduced CFTR function may alter redox properties of airway epithelial cells. Redox-sensitive GFP (roGFP1) and imaging microscopy were used to measure the redox potentials of the cytosol, endoplasmic reticulum (ER), mitochondria, and cell surface of cystic fibrosis nasal epithelial cells and CFTR-corrected cells. We also measured glutathione and cysteine thiol redox states in ...
متن کاملMicroRNA Expression in Cystic Fibrosis Airway Epithelium
MicroRNAs (miRs) have emerged as major regulators of the protein content of a cell. In the most part, miRs negatively regulate target mRNA expression, with sets of miRs predicted to regulate certain signaling pathways. The miR expression profile of endobronchial brushings is altered in people with cystic fibrosis (CF) compared to those without CF. How this impacts on CF has important implicatio...
متن کاملAnchored PDE4 regulates chloride conductance in wild-type and ΔF508-CFTR human airway epithelia.
Cystic fibrosis (CF) is caused by mutations in the gene encoding the cystic fibrosis transmembrane conductance regulator (CFTR) that impair its expression and/or chloride channel function. Here, we provide evidence that type 4 cyclic nucleotide phosphodiesterases (PDE4s) are critical regulators of the cAMP/PKA-dependent activation of CFTR in primary human bronchial epithelial cells. In non-CF c...
