The purpose of this study is to develop an integrated view of molecular mechanisms underlying CF lung disease severity.
Cystic fibrosis (CF) is a recessive genetic disorder caused by mutations in CF transmembrane conductance regulator (CFTR) gene. CF has multi-organ involvement, but respiratory disease is the major cause of morbidity and mortality. The median age of survival in CF is only 37 years, but there is a broad range of disease severity in the lung, even among patients with identical CFTR genotypes, including ΔF508 homozygotes.
This project holds great promise for defining a robust molecular phenotype for CF lung disease, which relates to prognosis, and new targets for therapy. By using a large and well-defined population of ΔF508 homozygotes who also have whole genome SNP data, and by studying gene expression across the whole transcriptome in a large number of samples of two relevant tissues (respiratory epithelium and transformed lymphocytes), we will be uniquely positioned to develop an integrated view of molecular mechanisms underlying CF lung disease severity.

In order to further enable physiopathology studies, the aim of this project is to validate an in vitro model of cystic fibrosis created using induced pluripotent stemcell (iPS) differentia...
Exercise is an important clinical feature in cystic fibrosis. Better exercise capacity has been associated with better patient outcomes and quality of life. Exercise-induced bronchospasm...
OBJECTIVES: Evaluate the efficacy and safety of lipid-mediated transfer of the cystic fibrosis transmembrane conductance regulator gene to nasal epithelium in patients with cystic f...
OBJECTIVES: I. Determine the stability of uridine triphosphate (UTP) and examine the metabolism of exogenous nucleotides on airway epithelial surfaces in patients with cystic fibrosis. ...
The risk of vitamin E deficiency is of primary concern in cystic fibrosis patients. However, early diagnosis and routine vitamin E supplementation can lead to its normal or even high levels. In the pr...
In healthy lungs, epithelial sodium channel (ENaC) is regulated by short, palate, lung, and nasal clone 1 (SPLUNC1). In cystic fibrosis (CF), ENaC is hyperactivated in part due to a loss of SPLUNC1 fu...
Cystic fibrosis diagnosis is dependent on the chloride ion concentration in the sweat test (≥60mEq/mL - recognized as the gold standard indicator for cystic fibrosis diagnosis). Moreover, the saliva...
The Australian Cystic Fibrosis Data Registry is positioning itself as an exemplar of a rare disease registry for the future. While it continues to inform cystic fibrosis (CF) clinicians of patterns of...
An autosomal recessive genetic disease of the EXOCRINE GLANDS. It is caused by mutations in the gene encoding the CYSTIC FIBROSIS TRANSMEMBRANE CONDUCTANCE REGULATOR expressed in several organs including the LUNG, the PANCREAS, the BILIARY SYSTEM, and the SWEAT GLANDS. Cystic fibrosis is characterized by epithelial secretory dysfunction associated with ductal obstruction resulting in AIRWAY OBSTRUCTION; chronic RESPIRATORY INFECTIONS; PANCREATIC INSUFFICIENCY; maldigestion; salt depletion; and HEAT PROSTRATION.
A chloride channel that regulates secretion in many exocrine tissues. Abnormalities in the CFTR gene have been shown to cause cystic fibrosis. (Hum Genet 1994;93(4):364-8)
A strain of mice widely studied as a model for cystic fibrosis. These mice are generated from embryonic stem cells in which the CFTR (cystic fibrosis transmembrane conductance regulator) gene is inactivated by gene targeting. As a result, all mice have one copy of this altered gene in all their tissues. Mice homozygous for the disrupted gene exhibit many features common to young cystic fibrosis patients, including failure to thrive, meconium ileus, and alteration of mucous and serous glands.
A species of STENOTROPHOMONAS, formerly called Xanthomonas maltophilia, which reduces nitrate. It is a cause of hospital-acquired ocular and lung infections, especially in those patients with cystic fibrosis and those who are immunosuppressed.
Intestinal obstruction caused by congealed MECONIUM in the distal ILEUM and CECUM. It presents shortly after birth as a failure to pass meconium and frequently occurs in infants with CYSTIC FIBROSIS.
