Many disease-causing mutations impair protein stability. Here, we explore a thermodynamic strategy to correct the disease-causing F508del mutation in the human cystic fibrosis transmembrane conductance regulator (hCFTR). F508del destabilizes nucleotide-binding domain 1 (hNBD1) in hCFTR relative to an aggregation-prone intermediate. We developed a fluorescence self-quenching assay for compounds that prevent aggregation of hNBD1 by stabilizing its native conformation. Unexpectedly, we found that dTTP and nucleotide analogs with exocyclic methyl groups bind to hNBD1 more strongly than ATP and preserve electrophysiological fun...

Cosme, Marie-Pierre Audrézet, Miyuki Nakakuki, Hiroshi Ishiguro, Claude Férec, Johanna Rommens, Ann HarrisIt is estimated that up to 5% of cystic fibrosis transmembrane conductance regulator (CFTR) pathogenic alleles are unidentified. Some of these errors may lie in noncoding regions of the locus and affect gene expression. To identify regulatory element variants in the CFTR locus, SureSelect-targeted enrichment of 460 kb encompassing the gene wa...

Cystic fibrosis (CF) ‐associated liver disease (CFLD) is a hepatobiliary complication of CF. Current diagnostic modalities rely on nonspecific assessments, whereas liver biopsy is the gold standard to assess severity of fibrosis. MicroRNAs (miRNAs) regulate liver disease pathogenesis and are proposed as diagnostic bio markers. We investigated the combined use of serum miRNAs and aspartate aminotransferase (AST) to platelet ratio (APRI) to diagnose and assess CFLD severity. This was a cross‐sectional cohort study of the circulatory miRNA signature of 124 children grouped by clinical, biochemical, and imaging ass essment...

In this study seven clinical M. abscessus complex strains and the M. abscessus reference strain ATCC19977 were used to find species-specific proteins for their use in immune assays. Six strains showed rough and smooth colony morphotypes simultaneously, two strains only showed rough mophotypes, resulting in 14 separate isolates. Clinical isolates were submitted to whole genome sequencing. Proteomic analysis was performed on bacterial lysates and culture supernatant of all 14 isolates. Species-specificity for M. abscessus complex was determined by a BLAST search for proteins present in all supernatants. Species-specific prot...
