Pharmacologic Inhibition of Epidermal Growth Factor Receptor Suppresses Nonalcoholic Fatty Liver Disease in a Murine Fast‐Food Diet Model

Bharat Bhushan, Swati Banerjee, Shirish Paranjpe, Kelly Koral, Wendy M. Mars, John W. Stoops, Anne Orr, William C. Bowen, Joseph Locker, George K. Michalopoulos – 7 May 2019 – Epidermal growth factor receptor (EGFR) is a critical regulator of hepatocyte proliferation and liver regeneration. Our recent work indicated that EGFR can also regulate lipid metabolism during liver regeneration after partial hepatectomy. Based on these findings, we investigated the role of EGFR in a mouse model of nonalcoholic fatty liver disease (NAFLD) using a pharmacological inhibition strategy.

Superior Wait‐List Outcomes in Patients with Alcohol‐Associated Liver Disease Compared With Other Indications for Liver Transplantation

Jeanne‐Marie Giard, Jennifer L. Dodge, Norah A. Terrault – 7 May 2019 – Alcohol‐associated liver disease (ALD) is the most common indication for liver transplantation (LT) in the United States and Europe. A 6‐month alcohol abstinence period has been required by many transplant programs prior to listing, which may influence wait‐list (WL) outcomes. Therefore, we examined WL events in patients with ALD versus non‐ALD with a special interest in whether these outcomes differed by sex.

Hippo Signaling Controls NLR Family Pyrin Domain Containing 3 Activation and Governs Immunoregulation of Mesenchymal Stem Cells in Mouse Liver Injury

Changyong Li, Yuting Jin, Song Wei, Yishuang Sun, Longfeng Jiang, Qiang Zhu, Douglas G. Farmer, Ronald W. Busuttil, Jerzy W. Kupiec‐Weglinski, Bibo Ke – 7 May 2019 – The Hippo pathway, an evolutionarily conserved protein kinase cascade, tightly regulates cell growth and survival. Activation of yes‐associated protein (YAP), a downstream effector of the Hippo pathway, has been shown to modulate tissue inflammation.

The Quality and Outcomes of Care Provided to Patients with Cirrhosis by Advanced Practice Providers

Elliot B. Tapper, Shengchen Hao, Menghan Lin, John N. Mafi, Heather McCurdy, Neehar D. Parikh, Anna S. Lok – 7 May 2019 – Cirrhosis is morbid and increasingly prevalent, yet the U.S. health care system lacks enough physicians and specialists to adequately manage patients with cirrhosis. Although advanced practice providers (APPs) can expand access to cirrhosis‐related care, their impact on the quality of care remains unknown.

Hepatocellular Carcinoma Xenografts Established From Needle Biopsies Preserve the Characteristics of the Originating Tumors

Tanja Blumer, Isabel Fofana, Matthias S. Matter, Xueya Wang, Hesam Montazeri, Diego Calabrese, Mairene Coto‐Llerena, Tujana Boldanova, Sandro Nuciforo, Venkatesh Kancherla, Luigi Tornillo, Salvatore Piscuoglio, Stefan Wieland, Luigi M. Terracciano, Charlotte K.Y. Ng, Markus H. Heim – 6 May 2019 – Hepatocellular carcinoma (HCC) is the second leading cause of cancer‐related deaths worldwide. Treatment options for patients with advanced‐stage disease are limited. A major obstacle in drug development is the lack of an in vivo model that accurately reflects the broad spectrum of human HCC.

OLFM4 Enhances STAT3 Activation and Promotes Tumor Progression by Inhibiting GRIM19 Expression in Human Hepatocellular Carcinoma

Yosuke Ashizawa, Satoshi Kuboki, Hiroyuki Nojima, Hideyuki Yoshitomi, Katsunori Furukawa, Tsukasa Takayashiki, Shigetsugu Takano, Masaru Miyazaki, Masayuki Ohtsuka – 2 May 2019 – Olfactomedin 4 (OLFM4) induces signal transducer and activator of transcription 3 (STAT3) activation by inhibiting gene associated with retinoid‐interferon‐induced mortality 19 (GRIM19), a strong STAT3 suppressor gene; however, the mechanisms of OLFM4 for regulating GRIM19‐STAT3 cascade in hepatocellular carcinoma (HCC) remain unclear.

NOD‐like receptor C4 Inflammasome Regulates the Growth of Colon Cancer Liver Metastasis in NAFLD

Koichiro Ohashi, Zhijun Wang, Yoon Mee Yang, Sandrine Billet, Wei Tu, Michael Pimienta, Suzanne L. Cassel, Stephen J. Pandol, Shelly C. Lu, Fayyaz S. Sutterwala, Neil Bhowmick, Ekihiro Seki – 1 May 2019 – Nonalcoholic fatty liver disease (NAFLD) enhances the growth and recurrence of colorectal cancer (CRC) liver metastasis. With the rising prevalence of NAFLD, a better understanding of the molecular mechanism underlying NAFLD‐associated liver metastasis is crucial. Tumor‐associated macrophages (TAMs) constitute a large portion of the tumor microenvironment that promotes tumor growth.
