Bile secretion is essential for whole body sterol homeostasis. Loss-of-function mutations in specific canalicular transporters in the hepatocyte disrupt bile flow and result in cholestasis. We show that two of these transporters, ABCB11 and ATP8B1, are functional targets of miR-33, a micro-RNA that is expressed from within an intron of SREBP-2. Consequently, manipulation of miR-33 levels in viv...

objective(s) the liver has major role in the organism homeostasis, interactions with other systems, synthesis and metabolism of bile production, drug detoxification and hormone inactivation. cholestasis can be defined as an impairment of the bile flow which can lead to hepatocytes necrosis and finally cirrhosis. some studies reported a gastric acid secretion reduction in cirrhotic subjects, whi...

bile duct ligation (bdl) is shown to induce cholestasis-related liver function impairments as well as consequent cognitive dysfunctions (i.e. impaired learning and memory formation). this study investigates the effects of cholestasis (14, 21 and 28 days post bile duct ligation) on spatial and non-spatial novelty detection, using a non-associative task. male mice weighing 30-35 g were used. chol...

Alagille syndrome (ALGS) is a multisystem autosomal dominant disorder caused by defects in the Notch signaling pathway. The classical criteria for ALGS diagnosis include bile duct paucity on liver biopsy in association with three of the following: Cholestasis, congenital heart disease, vertebral abnormalities, characteristic facial features, and posterior embryotoxon. However, the diagnosis is ...

Early detection of drug-induced cholestasis remains a challenge during drug development. We have developed and validated a biorelevant sandwich-cultured hepatocytes- (SCH) based model that can identify compounds causing cholestasis by altering bile acid disposition. Human and rat SCH were exposed (24-48h) to known cholestatic and/or hepatotoxic compounds, in the presence or in the absence of a ...

Background: Outcome of infantile intrahepatic cholestasis is highly variable. Aim to investigate various factors affecting outcome of infantile cholestasis. Methods: Retrospective study was conducted through data collection of 70 infant’s files who presented with intrahepatic cholestasis. They were divided into two groups according to the fate of jaundice at the end of the first year follow up....

INTRODUCTION Parenteral nutrition-associated cholestasis is well recognized phenomenon in the term and preterm infant receiving long-term parenteral nutrition. OBJECTIVES The aim of this study was to evaluate the effect of ursodeoxycholic acid (UDCA) use on cholestasis in newborns on prolonged TPN. METHODS A total of 56 infants were enrolled in this retrospective study: control group consis...

Progressive familial intrahepatic cholestasis is a serious disease of the liver, known as Byler disease, characterized by hepatocellular cholestasis. Severe pruritus and high serum bile acid concentrations are the most important diagnostic criteria of this autosomal recessive inherited disease. Here, we present a five-year-old boy with lichenification and enlargement of hands and feet as a sign...

Intrahepatic cholestasis is a rare but potentially fatal complication of sickle cell disease [1]. Sickle cell intrahepatic cholestasis (SCIC) is characterised by right upper quadrant pain, hepatomegaly and progressive hyperbilirubinaemia. To date 15 adult patients have been reported in the literature and only six survived [2]. We present a case of haemoglobin S/Beta thalassaemia with intrahepat...

OBJECTIVE To evaluate postpartum blood loss in women with treated intrahepatic cholestasis of pregnancy. METHODS In a retrospective case-control study, 15,083 deliveries including 348 women with intrahepatic cholestasis of pregnancy (2.3%) were analyzed from 2004 to 2014. To adjust for differences in baseline characteristics, a propensity analysis was performed and women in the control group ...
