The role of canalicular ABC transporters in cholestasis.
Cholestasis, a hallmark feature of hepatobiliary disease, is characterized by the retention of biliary constituents. Some of these constituents, such as bile acids, inflict damage to hepatocytes and bile duct cells. This damage may lead to inflammation, fibrosis, cirrhosis, and eventually carcinogenesis, sequelae that aggravate the underlying disease and deteriorate clinical outcome. Canalicula...
متن کاملMammalian ABC transporters in health and disease.
The ATP-binding cassette (ABC) transporters are a family of large proteins in membranes and are able to transport a variety of compounds through membranes against steep concentration gradients at the cost of ATP hydrolysis. The available outline of the human genome contains 48 ABC genes; 16 of these have a known function and 14 are associated with a defined human disease. Major physiological fu...
متن کاملABC Transporters and the Alzheimer’s Disease Enigma
Alzheimer's disease (AD) is considered the "disease of the twenty-first century." With a 10-fold increase in global incidence over the past 100 years, AD is now reaching epidemic proportions and by all projections, AD patient numbers will continue to rise. Despite intense research efforts, AD remains a mystery and effective therapies are still unavailable. This represents an unmet need resultin...
متن کاملTransporters on demand: intrahepatic pools of canalicular ATP binding cassette transporters in rat liver.
ABC transporter trafficking in rat liver induced by cAMP or taurocholate and [(35)S]methionine metabolic labeling followed by subcellular fractionation were used to identify and characterize intrahepatic pools of ABC transporters. ABC transporter trafficking induced by cAMP or taurocholate is a physiologic response to a temporal demand for increased bile secretion. Administration of cAMP or tau...
متن کاملHepatobiliary ABC transporters: physiology, regulation and implications for disease.
The liver plays a key role in the metabolic conversion and elimination of endo- and xenobiotics. Hepatobiliary transport of many of these compounds is mediated by several ATP-binding cassette (ABC) transporters expressed at the canalicular membrane of the hepatocyte. Impaired function of these ABC transporters leads to impaired bile formation or cholestasis and mutations in these genes are asso...
