    Polygenic Architecture Informs Potential Vulnerability to Drug-Induced Liver Injury

    The polygenic risk score predicted the susceptibility to drug-induced liver injury in patients treated with fasiglifam, amoxicillin–clavulanate or flucloxacillin and in primary hepatocytes and stem cell-derived organoids from multiple donors treated with over ten different drugs.
    [Nature Medicine]

    Abstract


    In this webinar on hepatic organoids review the biological characteristics and practical considerations of adding organoids to your research.

    Mitochondria-Located circRNA SCAR Alleviates NASH via Reducing mROS Output

    Scientists observed that Steatohepatitis-associated circRNA ATP5B Regulator (SCAR), which is located in mitochondria, inhibited mitochondrial ROS output and fibroblast activation.

    Potent Anti-Malarial Human Monoclonal Antibody Targets Circumsporozoite Protein Minor Repeats and Neutralizes Sporozoites in the Liver

    Isothermal titration calorimetry and multiphoton microscopy showed that L9 and the other most protective mAbs bound PfCSP with two binding events and mediated protection by killing SPZ in the liver and by preventing their egress from sinusoids and traversal of hepatocytes.

    Regulation
    of Hepatic Insulin Signaling and Glucose Homeostasis by Sphingosine Kinase 2

    Investigators generated liver-specific sphingosine kinase 2 (SphK2) knockout mice, demonstrating that SphK2 in the liver was essential for insulin sensitivity and glucose homeostasis.

    Cancer-Associated
    Fibroblasts Provide a Stromal Niche for Liver Cancer Organoids that Confers Trophic Effects and Therapy Resistance

    Researchers established murine and human 3D co-culture models of liver tumor organoids with cancer associated fibroblasts (CAFs). CAFs promoted tumor organoid growth in co-culture with direct cell-cell contact and in trans-well system via paracrine signaling.

    Hsa_Circ_0001955 Enhances In Vitro
    Proliferation, Migration and Invasion of Hepatocellular Carcinoma Cells through miR-145-5p/NRAS Axis

    Functional experiments revealed that knockdown of hsa_circ_0001955 markedly inhibited proliferation, migration and invasion of hepatocellular carcinoma, and its overexpression led to opposite effects.

    LIN28B-AS1-IGF2BP1 Binding Promotes Hepatocellular Carcinoma Cell Progression

    The authors showed that LIN28B-AS1 was expressed in established/primary human hepatocellular carcinoma (HCC) cells and HCC tissues. RNA-immunoprecipitation and RNA pull-down results confirmed that LIN28B-AS1 directly associated with IGF2BP1 protein in HCC cells.

    Model of Intrahepatic Metastasis of Hepatocellular Carcinoma: Establishment and Characteristic

    Investigators established a model of hepatocellular carcinoma (HCC) with intrahepatic metastasis and noticed some differential appearances in different HCC cell lines. Luciferase-transfected HCC cell lines MHCC97-H and PLC/PRF/5 were inoculated into SCID mice via spleen.

    C Virus Enhances Rubicon Expression, Leading to Autophagy Inhibition and Intracellular Innate Immune Activation

    In Huh-7 cells harbouring the hepatitis C virus (HCV) replicon, Rubicon knockdown downregulated the expression of type 1 interferon-related genes and upregulated HCV replication.

    A Dietary Anthocyanin Cyanidin-3-O-Glucoside
    Binds to PPARs to Regulate Glucose Metabolism and Insulin Sensitivity in Mice

    Cyanidin-3-O-glucoside increased glucose uptake in HepG2 cells and C2C12 myotubes and induced the rate of hepatic fatty acid oxidation. C3G directly interacted with and activated PPARs, with the highest affinity for PPARα.

    Hepatocellular Carcinoma—The Influence of Immunoanatomy and the Role of Immunotherapy

    Investigators summarize hepatocellulr carcinoma (HCC), its staging system, current therapy and immunotherapy medications currently being utilized or studied in the treatment of HCC with the hopes of highlighting what is being done and suggesting what needs to be done in the future to champion this therapy as an effective option.

    Post-Transcriptional Regulation by AU-Rich Element-Binding Proteins in Liver Inflammation and Cancer

    The authors discuss current knowledge of the roles and functions of AU-rich element-binding proteins (AUBPs) in liver diseases and cancer. The relevance of AUBPs as potential biomarkers for different stages of FLD and HCC, or as therapeutic targets for these diseases, are also highlighted.
