Endothelial Wnts regulate β‐catenin signaling in murine liver zonation and regeneration: A sequel to the Wnt–Wnt situation

Morgan Preziosi, Hirohisa Okabe, Minakshi Poddar, Sucha Singh, Satdarshan P. Monga – 21 June 2018 – β‐Catenin in hepatocytes, under the control of Wnts, regulates pericentral gene expression. It also contributes to liver regeneration (LR) after partial hepatectomy (PH) by regulating cyclin‐D1 gene expression as shown in the β‐catenin and Wnt coreceptors low‐density lipoprotein receptor‐related protein 5/6 conditional knockouts (KO).

Pro: Steroids Can Be Withdrawn After Transplant in Recipients With Autoimmune Hepatitis

Avash Kalra, James R. Burton, Lisa M. Forman – 19 June 2018 – Corticosteroids have been a mainstay of immunosuppression following liver transplantation. However, evolution in the field of transplant immunology has produced steroid‐free options, resulting in most transplant centers weaning steroids after transplant within days to months—an evidence‐based management decision. Patients with autoimmune hepatitis (AIH), however, receive corticosteroids prior to transplant. This raises the question of whether these patients should also be weaned from corticosteroids.

The Genetic Architecture of Diet‐Induced Hepatic Fibrosis in Mice

Beaven, Adriana Huertas‐Vazquez, Aldons J. Lusis – 16 June 2018 – We report the genetic analysis of a “humanized” hyperlipidemic mouse model for progressive nonalcoholic steatohepatitis (NASH) and fibrosis.

Nuclear receptors and liver disease: Summary of the 2017 basic research symposium

Melanie Tran, Yanjun Liu, Wendong Huang, Li Wang – 14 June 2018 – The nuclear receptor superfamily contains important transcriptional regulators that play pleiotropic roles in cell differentiation, development, proliferation, and metabolic processes to govern liver physiology and pathology. Many nuclear receptors are ligand‐activated transcription factors that regulate the expression of their target genes by modulating transcriptional activities and epigenetic changes.

Con: Steroids Should Not Be Withdrawn in Transplant Recipients With Autoimmune Hepatitis

Eleni Theocharidou, Michael A. Heneghan – 12 June 2018 – Autoimmune liver diseases (AILDs) can recur following liver transplantation (LT) despite immunosuppressive therapy, with implications for graft survival. Although the evidence is not robust, disease recurrence seems to occur in the presence of less intense and/or steroid‐free immunosuppression (IS) in particular in the case of autoimmune hepatitis (AIH). The main risk factor for AIH recurrence is the severity of disease activity in the explant and potential donor/recipient human leukocyte antigen D‐related 3 (DR3) mismatch.

An Association Between Core Mutations in Hepatitis B Virus Genotype F1b and Hepatocellular Carcinoma in Alaskan Native People

Sanae Hayashi, Anis Khan, Brenna C. Simons, Chriss Homan, Takeshi Matsui, Kenji Ogawa, Keigo Kawashima, Shuko Murakami, Satoru Takahashi, Masanori Isogawa, Kazuho Ikeo, Masashi Mizokami, Brian J. McMahon, Yasuhito Tanaka – 12 June 2018 – Hepatitis B virus (HBV) genotype F1b infection is strongly associated with hepatocellular carcinoma (HCC) in young Alaskan Native (AN) people. However, the mechanisms by which genotype F1b causes HCC are unclear. Here, we analyzed the clinical and virological significance of genotype F1b in long‐term serial samples from 20 HCC patients with HBV infection.
