Acute Hepatic Porphyrias: Review and Recent Progress

Bruce Wang, Sean Rudnick, Brent Cengia, Herbert L. Bonkovsky – 20 December 2018 – The acute hepatic porphyrias (AHPs) are a group of four inherited diseases of heme biosynthesis that present with episodic, acute neurovisceral symptoms. The four types are 5‐aminolevulinic acid (ALA) dehydratase deficiency porphyria, acute intermittent porphyria, hereditary coproporphyria, and variegate porphyria. Their diagnoses are often missed or delayed because the clinical symptoms mimic other more common disorders.

Human Immunodeficiency Virus/Hepatitis C Virus (HCV) Co‐infected Patients With Cirrhosis Are No Longer at Higher Risk for Hepatocellular Carcinoma or End‐Stage Liver Disease as Compared to HCV Mono‐infected Patients

Dominique Salmon‐Ceron, Pierre Nahon, Richard Layese, Valérie Bourcier, Philippe Sogni, Firouze Bani‐Sadr, Etienne Audureau, Laurence Merchadou, François Dabis, Linda Wittkop, Françoise Roudot‐Thoraval, for the ANRS CO12 CirVir and ANRS CO13 HEPAVIH study groups – 19 December 2018 – It is widely accepted that human immunodeficiency virus (HIV) infection is a risk factor for increased severity of hepatitis C virus (HCV) liver disease.

Bile‐Derived Organoids From Patients With Primary Sclerosing Cholangitis Recapitulate Their Inflammatory Immune Profile

Carol J. Soroka, David N. Assis, Leina S. Alrabadi, Scott Roberts, Laura Cusack, Ariel B. Jaffe, James L. Boyer – 18 December 2018 – Primary sclerosing cholangitis (PSC) is a heterogeneous and progressive fibroinflammatory cholangiopathy with no known etiology or effective treatment. Studies of PSC are limited due to difficulty in accessing the cholangiocyte, the small percentage of these cells in the liver, instability of in vitro culture systems, and reliance on samples from end‐stage disease.

5‐Hydroxytryptamine Receptor 1D Aggravates Hepatocellular Carcinoma Progression Through FoxO6 in AKT‐Dependent and Independent Manners

Xueliang Zuo, Zhiqiang Chen, Juan Cai, Wen Gao, Yao Zhang, Guoyong Han, Liyong Pu, Zhengshan Wu, Wei You, Jianjie Qin, Xinzheng Dai, Hongbing Shen, Jindao Wu, Xuehao Wang – 18 December 2018 – Serotonin and its receptors have been shown to play critical regulatory roles in cancer biology. Nevertheless, the contributions of 5‐hydroxytryptamine 1D (5‐HT1D), an indispensable member of the serotonergic system, to hepatocellular carcinoma (HCC) remain unknown. The present study demonstrated that the 5‐HT1D expression level was significantly up‐regulated in HCC tissues and cell lines.

Aging‐Related Expression of Twinfilin‐1 Regulates Cholangiocyte Biological Response to Injury

Luca Maroni, Claudio Pinto, Debora Maria Giordano, Stefania Saccomanno, Jesus M. Banales, Daniele Spallacci, Maria Cristina Albertini, Fiorenza Orlando, Mauro Provinciali, Malgorzata Milkiewicz, Espen Melum, Ibone Labiano, Piotr Milkiewicz, Chiara Rychlicki, Luciano Trozzi, Marina Scarpelli, Antonio Benedetti, Gianluca Svegliati Baroni, Marco Marzioni – 18 December 2018 – Disorders of the biliary tree develop and progress differently according to patient age. It is currently not known whether the aging process affects the response to injury of cholangiocytes.
