    Co-Regulation of Hepatic Steatosis by Ferritinophagy and Unsaturated Fatty Acid Supply

    Researchers conducted a series of Ncoa4 gain- and loss-of-function experiments to examine how ferritinophagy affected lipid metabolism through phenotypic and lipidomic analyses both in vitro and in vivo.

    Inhibition of TWEAK/Tnfrsf12a Axis Protects against Acute Liver Failure by Suppressing RIPK1-Dependent Apoptosis

    Investigators found that expression of hepatic tumor necrosis factor-like weak inducer of apoptosis (TWEAK) and its receptor tumor necrosis factor receptor superfamily member 12A (Tnfrsf12a) were significantly increased during acute liver failure induced by thioacetamide or acetaminophen.

    RBCK1 Promotes Hepatocellular Carcinoma Metastasis and Growth by Stabilizing RNF31

    Scientists investigated the role of RNF31 and RBCK1 in HCC and showed that RNF31 and RBCK1 were overexpressed in HCC and that upregulation of RNF31 and RBCK1 indicated poor clinical outcomes in patients with HCC.

    Abstract

    Integrating a Dynamic Central Metabolism Model of Cancer Cells with a Hybrid 3D Multiscale Model for Vascular Hepatocellular Carcinoma Growth

    Investigators extended a previously published multiscale model of vascular tumor growth, and integrated it with an experimentally verified network of central metabolism in HEPG2 cells.

    Spatiotemporal Expression of HMGB2 Regulates Cell Proliferation and Hepatocyte Size During Liver Regeneration

    Researchers investigated the functional role of high-mobility group box 2 (HMGB2), a chromatin protein in liver regeneration using wild-type and HMGB2-knockout mice.

    Abstract

    SLAMF1 Is Expressed and Secreted by Hepatocytes and the Liver in Non-Alcoholic Fatty Liver Disease

    To test whether signaling lymphocytic activation molecule 1 (SLAMF1) was expressed by hepatocytes, scientists treated HepG2 cells and primary murine hepatocytes with palmitic acid to induce a state of lipotoxicity mimicking non-alcoholic steatohepatitis.

    Abstract

    Targeting IRE1α and Perk in the Endoplasmic Reticulum Stress Pathway Attenuates Fatty Acid-Induced Insulin Resistance in Bovine Hepatocytes

    The authors investigated whether endoplasmic reticulum stress played a role in nonesterified fatty acid-induced hepatic insulin resistance in dairy cows.
