    Ribonuclease
    7-Driven Activation of ROS1 Is a Potential Therapeutic Target in Hepatocellular Carcinoma

    Oncogenic function of RNase7 was analyzed by cell proliferation, migration, invasion assays and xenograft mouse model. The anti-ROS1 inhibitor treatment efficacy was evaluated in hepatocellular carcinoma patient-derived xenograft and orthotopic models.

    Hepatocellular Carcinoma with PARP1 and DNA-PK Inhibitors

    Combining olaparib with NU7441, a DNA-PKcs inhibitor that blocks nonhomologous end-joining in hepatocellular carcinoma (HCC), synergistically suppressed HCC growth in both mice and HCC patient-derived-xenograft models.

    Abstract

    LncRNA
    LL22NC03-N14H11.1 Promoted Hepatocellular Carcinoma Progression through Activating MAPK Pathway to Induce Mitochondrial Fission

    Dysregulated lncRNAs in hepatocellular carcinoma (HCC) were identified through circlncRNAnet and GEPIA bioinformatics tools. Biological function of LL22NC03-N14H11.1 in HCC was detected by CCK-8 assay, flow cytometry analysis, transwell invasion, and wound healing assays.

    EFTUD2
    Maintains the Survival of Tumor Cells and Promotes Hepatocellular Carcinoma Progression via the Activation of STAT3

    Immunohistochemical analysis performed on two independent hepatocellular carcinoma (HCC) cohorts confirmed the upregulation of EFTUD2 in HCC tissues and further suggested that a high level of EFTUD2 expression predicted shorter overall and recurrence-free survival in HCC patients.

    The Effects of Fructose and Metabolic Inhibition on Hepatocellular Carcinoma

    Researchers examined the metabolic effects of fructose on hepatocellular carcinoma growth in vitro and in vivo. Fructose sugar was found to reduce cell growth in vitro, and caused alterations in the expression of enzymes involved in the serine-glycine synthesis and pentose phosphate pathways.

    Type-Specific Roles of CD38 in the Interactions of Isoniazid with NAD+ in the Liver

    Because N-acetyltransferase (NAT) is expressed in hepatocytes, whereas CD38 is expressed in Kupffer cells and hepatic stellate cells, investigators explored cell type-specific roles of CD38 in the formation of a primary INH metabolite mediated isoniazid (INH)-β-nicotinamide adenine dinucleotide (NAD) as well as INH-NAD.

    Abstract

    NFAT2
    Overexpression Suppresses the Malignancy of Hepatocellular Carcinoma through Inducing Egr2 Expression

    The pcDNA3.1-NFAT2 plasmid was transfected into HepG2 cells to construct NFAT2 overexpressed HepG2 cells. Then, the chemical count kit-8 cell viability assay, Annexin V-FITC apoptosis detection, EdU labeling proliferation detection, transwell and wound healing experiments were performed.

    p53 Inhibits Interleukin 10-Induced Activated Hepatic Stellate Cell Senescence and Fibrotic Degradation In Vivo

    Scientists explored whether p53 played a crucial role in the senescence of activated hepatic stellate cells and degradation of collagen mediated by interleukin-10.

    Abstract

    Pathogen infection studies lacked an optimal culture system. Then she used organoids.

    Hepatocyte Growth Factor/C-Mesenchymal–Epithelial Transition Factor Axis in Hepatocellular Carcinoma: Rationale and Therapeutic Strategies

    The authors collected the evidence of HGF/c‐Met as a tumor progression and prognostic marker, discussed the anti‐c‐Met therapy in vitro, summarized the outcome of c‐Met inhibitors in clinical trials, and identified potential impetus for future anti‐c‐Met treatments.

    Abstract

    Immunotherapy for Hepatocellular Carcinoma: A 2021 Update

    Investigators demonstrate that combination of different immunotherapies or immunotherapy with other modalities results in better overall survival and progression ­free survival compared to single immunotherapy agent.

    Hepatitis
    Is Still a Silent Killer in Africa and Elsewhere

    New blood tests and drugs for this deadly disease have already saved millions of lives. But for millions more around the world, the celebration is bittersweet and the revolution in diagnosis and treatment remains a distant dream.
