    P450 1A2 Overcomes Nuclear Factor Kappa B-Mediated Sorafenib Resistance in Hepatocellular Carcinoma

    To investigate whether CYP1A2 and NF‐κB p65 played roles in sorafenib desensitization, the authors established sorafenib-resistant (SR) hepatocellular carcinoma cells. SR cells decreased the expression of CYP1A2 along with the upregulation of NF‐κB p65.

    The
    Novel Interplay between CD44 Standard Isoform and the Caspase-1/IL1B Pathway to Induce Hepatocellular Carcinoma Progression

    Scientists observed that cluster differentiation 44 standard isoform (CD44s) was responsible for caspase-1/IL1B activation both in hepatocellular carcinoma (HCC) tissues and five HCC cell lines. In normoxia conditions, CD44s knockdown repressed the activation of caspase-1/IL1B via stimulating AMPK-mediated autophagy.

    The
    mRNA of TCTP Functions as a Sponge to Maintain Homeostasis of TCTP Protein Levels in Hepatocellular Carcinoma

    Investigators found that translationally controlled tumor protein (TCTP) protein was overexpressed in hepatocellular carcinoma patients but TCTP mRNA expression levels were reversed.

    Fate and Functional Roles of Prominin 1+ Cells in Liver Injury and Cancer

    Researchers showed by genetic lineage tracing that PROM1+ cells were derived in part from hepatocytes in alcoholic hepatitis and became tumor cells in mice with diethyl nitrosamine-initiated, Western alcohol diet-promoted liver tumorigenesis.

    A Lipidomic Signature Complements Stemness Features Acquisition in Liver Cancer Cells

    Scientists found definite lipidomic and transcriptomic changes in the hepatocellular carcinoma lines upon knockdown of macroH2A1 or focal adhesion kinase, in line with the acquisition or loss of stemness features.

    Modulation
    of the Liver Immune Microenvironment by the Adeno-Associated Virus Serotype 8 Gene Therapy Vector

    Investigators demonstrated the immune response mediated by an adeno-associated viruse (AAV) vector in a mouse model. Mice were infected intravenously with 4×10ˆ12 cp/kg of AAV8 and the ensuing immune response was analyzed using intravital microscopy, over a period of weeks.

    Inhibitors and Radiation Potentiate Liver Cell Death In Vitro. Do Hepatocellular Carcinomas Have an Achilles’ Heel?

    Cell cytotoxicity was measured by clonogenic survival or relative cell growth and the DNA damage response using immunological-based techniques in Hep3B, PLC/PRF/5, HepG2- and HepaRG-derived models.
