General descriptionCystic Fibrosis (CF) is a lethal autosomal recessive disease caused by mutations in the CF transmembrane conductance regulator (CFTR) gene which functions as a cAMP-activated and phosphorylated-regulated Cl channel. The predominant mutation in the CFTR gene is a trinucleotide deletion that results in loss of a phenylalanine at amino acids 508 (ΔF508) in the CFTR protein. This mutation accounts for ~66% of all CF alleles .
CFBE41o- 4.7 WT-CFTR Human CF Bronchial Epithelial Cell line is a subclone derived from the electroporation of the parental CFBE41o- cell line with an Epstein-Barr virus (EBV)-based episomal pCEPβ vector containing the 4.7 kb wild-type CFTR open reading frame (ORF) cDNA and a Hygromycin B resistance gene . The parental CFBE41o- is a CF human bronchial epithelial cell line, derived from a CF patient homozygous for the ΔF508 CFTR mutation and immortalized with the origin-of-replication defective SV40 plasmid (pSVori-) .
Established CF bronchial epithelial cell lines that are complemented with either wild-type or ΔF508CFTR mRNA will help provide insights into the relationship between transgene-derived CFTR mRNA expression and rescue of cAMP-dependent Cl transport function.
ApplicationCFBE41o- 4.7 WT-CFTR human CF bronchial epithelial cell line may be used to study the relationship between CFTR mRNA expression and Cl transport function.
