Cystic fibrosis transmembrane regulator potentiators as promising cystic fibrosis therapies.
Summary of "Cystic fibrosis transmembrane regulator potentiators as promising cystic fibrosis therapies."
Introduction: Several types of mutations in the cystic fibrosis transmembrane regulator (CFTR) gene lead to abnormal CFTR protein and alterations of chloride and sodium transmembrane transportation in cystic fibrosis (CF). Some investigational compounds such as VX-770 can improve CFTR protein function. Areas covered: This paper discusses the results of a Phase II study investigating the safety and efficacy of VX-770 in patients with CF. Expert opinion: VX-770 is able to improve chloride and sodium transportation and has a good safety profile. Although such compounds have limited therapeutic targeting potential, preliminary results show great promise in the context of CF therapy.

Medical and Biotech [MESH] Definitions
Cystic Fibrosis Transmembrane Conductance Regulator
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)
Cystic Fibrosis
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.
Mice, Inbred Cftr
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.
Stenotrophomonas Maltophilia
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.
Drainage, Postural
A rehabilitation therapy for removal of copious mucus secretion from the lung of patients with diseases such as CHRONIC BRONCHITIS; BRONCHIECTASIS; PULMONARY ABSCESS; or CYSTIC FIBROSIS. The patient's head is placed in a downward incline (so the TRACHEA is inferior to the affected area) for 15- to 20-minute sessions.
