: Bile acids (BAs) play critical physiological functions in cholesterol homeostasis and deregulation of BA metabolism causes cholestatic liver injury. Maternally expressed gene 3 (MEG3) was recently shown as a potential tumor suppressor, however its basic hepatic function remains elusive. Using RNA pull-down with biotin-labeled sense or anti-sense MEG3RNA followed by mass spectrometry, we identified RNA binding protein polypyrimidine tract-binding protein 1 (PTBP1) as a MEG3 interaction protein and validated their interaction by RNA immunoprecipitation (RIP)...

Chemical toxicity is conventionally evaluated in animal models. However, animal models are resource intensive; moreover, they face ethical and scientific challenges because the outcomes obtained by animal testing may not correlate with human responses. To develop an alternative method for assessing chemical toxicity, we investigated the feasibility of using chemical-induced genome-wide expression changes in cultured human cells to predict the potential of a chemical to cause specific organ injuries in humans...

Drug-induced cholestasis (DIC) is poorly understood and its preclinical prediction is mainly limited to assessing the compound's potential to inhibit the bile salt export pump (BSEP). Here, we evaluated two 3D spheroid models, one from primary human hepatocytes (PHH) and one from HepaRG cells, for the detection of compounds with cholestatic liability. By repeatedly co-exposing both models to a set of compounds with different mechanisms of hepatotoxicity and a non-toxic concentrated bile acid (BA) mixture for 8 days we observed a selective synergistic toxicity of compounds known to cause cholestatic or mixed cholestatic/hepatocellular toxicity and the BA mixture compared to exposure to the compounds alone, a phenomenon that was more pronounced after extending the exposure time to 14 days...

Bile Salt Export Pump (BSEP) Deficiency disease, including Progressive Familial Intrahepatic Cholestasis type 2 (PFIC2), is a rare disease, usually leading within the first ten years to portal hypertension, liver failure, hepatocellular carcinoma. Often liver transplantation is needed. Sodium 4-phenylbutyrate (4-PB) seems to be a potential therapeutic compound for PFIC2. Psychiatric side effects in the adolescent population are little known and little studied since the drug used to treat children and infants...

AIMS: Patients with chronic liver disease sometimes develop cholestasis, which induces severe whole-body pruritus that may disrupt daily activities and sleep. To determine the efficacy of nalfurafine hydrochloride (5 µg), which is a selective κ-opioid receptor agonist, in improving pruritus, we conducted a double-blind placebo-controlled study in patients with chronic liver disease with refractory pruritus. Nalfurafine hydrochloride at 2.5 µg was also used to evaluate the dose-response relationship...

History and admission findings: We report on a 76-year-old man presenting with painless jaundice who developed dialysis-dependent acute kidney injury. Investigations: Biliary tract was examined with endoscopy, in addition kidney biopsy was performed. Diagnosis, treatment and course: A stenosing process could be seen in the biliary tract, leading to stent implantation. However, jaundice did not resolve. Kidney biopsy revealed bile casts indicating cholemic nephropathy. After switch of concomitant medication, hyperbilirubinemia resolved and kidney function was completely restored...

BACKGROUND: Intrahepatic cholestasis of pregnancy (ICP) is a specific pregnancy-related disorder without standard medical therapies. Ursodeoxycholic acid (UDCA) is the most used medicine, but the efficacy and safety of UDCA remain uncertain. Several meta-analyses had been made to assess the effects of UDCA in ICP. However, the samples were not large enough to convince obstetricians to use UDCA. We conducted a meta-analysis to evaluate the effects and safety of UDCA in patients with ICP, which included only randomized controlled trials (RCTs)...

Estrogen-induced cholestasis, known as intrahepatic cholestasis of pregnancy (ICP), is an estrogen-related liver disease that is widely recognized as female or pregnancy-specific. Our previous findings showed that the synthetic estrogen, 17α-ethinylestradiol (EE), induced cholestatic injury through ERK1/2-LKB1-AMP-activated protein kinase (AMPK) signaling pathway and its mediated suppression of farnesoid X receptor (FXR). To investigate the role played by bile acids in EE-induced cholestasis, we evaluated the effects of chenodeoxycholic acid (CDCA), ursodeoxycholic acid (UDCA) and deoxycholic acid (DCA) on sandwich cultured rat primary hepatocytes (SCRHs) and an in vivo rat model...

:  Background and aims. Steroid-related hepatotoxicity has become one of the most relevant causes of drug induced liver cholestasis. Some patients do not improve after standard medical treatment (SMT) and may therefore require other approaches, like extracorporeal liver support. MATERIAL AND METHODS: We report four cases of patients with pruritus, abnormal liver function tests and biopsy-proven anabolic steroid-induced cholestasis who were unresponsive to SMT. They underwent treatment with albumin dialysis (Molecular Adsorbent Recirculating System -MARS®-)...

Hepatitis E virus (HEV) infections are the most common cause of acute hepatitis, but they can also take a chronic course. There is no specific therapy for acute hepatitis, and current treatment is supportive. Choosing ribavirin as the first-line therapy for chronic HEV is advisable, especially in solid organ transplant patients. Pegylated interferon-α has been used successfully for treatment of hepatitis E but is associated with major side effects. Cholestasis is one of the most common, but devastating, manifestations in hepatitis E...

Tauroursodeoxycholic acid (TUDCA) is a cytoprotective ER stress inhibitor and chemical chaperone. It has therapeutic potential in a wide array of diseases but a specific macromolecular target or molecular mechanism of action remains obscure. This Letter describes an effective new synthetic approach to taurine conjugation of bile acids which we used to prepare 3α-dansyl TUDCA (4) as a probe for TUDCA actions. As a model of ER stress we used the hepatocarcinoma cell line HUH7 and stimulation with either deoxycholic acid (DCA, 200μM) or tunicamycin (5μg/ml) and measured levels of Bip/GRP78, ATF4, CHOP and XBP1s/XBP1u...
