We used the Xenopus laevis oocyte expression system to characterize adenosine 3',5'-cyclic monophosphate (cAMP) activation of the cystic fibrosis transmembrane conductance regulator (CFTR). With conventional two-microelectrode voltage-clamp techniques, we recorded transmembrane conductance (Gm) and membrane current (Im). Using five different sine wave(More)
It is often challenging for the clinician interested in cystic fibrosis (CF) to interpret molecular genetic results, and to integrate them in the diagnostic process. The limitations of genotyping technology, the choice of mutations to be tested, and the clinical context in which the test is administered can all influence how genetic information is(More)
With the advent of whole-genome and whole-exome sequencing, high-quality catalogs of recurrently mutated cancer genes are becoming available for many cancer types. Increasing access to sequencing technology, including bench-top sequencers, provide the opportunity to re-sequence a limited set of cancer genes across a patient cohort with limited processing(More)
CFTR transcripts have been qualitatively and quantitatively analysed in nasal epithelial and vas deferens cells by means of reverse transcription PCR. Alternative splicing of exon 9, which is known to occur in nasal epithelial cells, also occurred in vas deferens cells. The extent of this alternative splicing was determined by the allele present at the Tn(More)
BACKGROUND The cystic fibrosis (CF) basic defect, caused by dysfunction of the apical chloride channel CFTR in the gastrointestinal and respiratory tract epithelia, has not been employed so far to support the role of CF modifier genes. METHODS Patients were selected from 101 families with a total of 171 F508del-CFTR homozygous CF patients to identify CF(More)
Frequency of INherited Disorders database (FINDbase) (http://www.findbase.org) is a relational database, derived from the ETHNOS software, recording frequencies of causative mutations leading to inherited disorders worldwide. Database records include the population and ethnic group, the disorder name and the related gene, accompanied by links to any(More)
BACKGROUND Primary ciliary dyskinesia (PCD) is a rare disorder with variable disease progression. To date, mutations in more than 20 different genes have been found. At present, PCD subtypes are described according to the ultrastructural defect on transmission electron microscopy (TEM) of the motile cilia. PCD with normal ultrastructure (NU) is rarely(More)
BACKGROUND This study describes the functional interaction between the putative Ca2+ channel TRP4 and the cystic fibrosis transmembrane conductance regulator, CFTR, in mouse aorta endothelium (MAEC). RESULTS MAEC cells express CFTR transcripts as shown by RT-PCR analysis. Application of a phosphorylating cocktail activated a Cl- current with(More)
The Cosmopolitan Chicken Project is an artistic undertaking of renowned artist Koen Vanmechelen. In this project, the artist interbreeds domestic chickens from different countries aiming at the creation of a true Cosmopolitan Chicken as a symbol for global diversity. The unifying theme is the chicken and the egg, symbols that link scientific, political,(More)
