Ethinylestradiol (EE) induces intrahepatic cholestasis in experimental animals being its derivative, ethinylestradiol 17beta-glucuronide, a presumed mediator of this effect. To test whether glucuronidation is a relevant step in the pathogenesis of cholestasis induced by EE (5 mg/kg b.wt. s.c. for 5 consecutive days), the effect of simultaneous administration of galactosamine (200 mg/kg b.wt. i....
The bile salt export pump (BSEP, ABCB11) is predominantly responsible for the efflux of bile salts, and disruption of BSEP function is often associated with altered hepatic homeostasis of bile acids and cholestatic liver injury. Accumulating evidence suggests that many drugs can cause cholestasis through interaction with hepatic transporters. To date, a relatively strong association between dru...

Cholestasis has limited therapeutic options and is associated with high morbidity and mortality. The A(1) adenosine receptor (A(1)AR) was postulated to participate in the pathogenesis of hepatic fibrosis induced by experimental extrahepatic cholestasis; however, the contribution of A(1)AR to intrahepatic cholestatic liver injury remains unknown. Here, we found that mice lacking A(1)AR were resi...
Class III multidrug resistance P-glycoproteins, mdr2 in mice and MDR3 in human, are canalicular phospholipid translocators involved in biliary phospholipid (phosphatidylcholine) excretion.The role of a MDR3 (ABCB4) gene defect in liver disease has been initially proven in a subtype of progressive familial intrahepatic cholestasis called PFIC3, a severe pediatric liver disease that may require l...
Cholestasis is a serious manifestation of liver diseases with limited therapies. Rhubarb, a widely used herbal medicine, has been frequently used at a relatively large dose for treating cholestasis. However, whether large doses are optimal and the therapeutic mechanism remain unclear. To explore these questions, the anti-cholestatic effect of five doses of rhubarb (0.21, 0.66, 2.10, 6.60, and 2...
BACKGROUND Following bile duct ligation (BDL) endogenous opioids accumulate in plasma and play a role in the pathophysiology and manifestation of cholestasis. Evidence of centrally mediated induction of liver injury by exogenous opioid agonist administration, prompts the question of whether opioid receptor blockade by naltrexone can affect cholestasis-induced liver injury. METHODS Cholestasis...
Background: Neonatal cholestasis is an important disease of the liver and biliary ducts in infancy. In neglected cases, the disease has irreversible complications. Idiopathic neonatal hepatitis, biliary atresia, TORCH infections and choledochal cyst are important causes of neonatal cholestasis. The aim of this study was to determine the causes of cholestasis among neonates admitted to the Child...
A major function of the liver is the formation of bile and hepatobiliary excretion of endogenous substances and xenobiotics, such as chemicals, drugs, and their metabolites. Cholestasis is a general condition of multiple etiologies, hereditary and acquired, in which bile excretion from the liver is attenuated or blocked. In some forms of cholestasis, cholesterol metabolism is perturbed, resulti...
Neuropeptide Y (NPY) is a key factor in the neurochemical control of food intake, and obstructive cholestasis can be associated with disturbances in food intake. Our aim in this study was to determine whether obstructive cholestasis in the rat is associated with defective central responsiveness to NPY. Cholestasis was induced in rats by surgical bile duct resection. Rats with obstructive choles...
