    DRAM1 Increases the Secretion of PKM2-Enriched Extracellular Vesicles from Hepatocytes to Promote Macrophage Activation and Disease Progression in Alcohol-Related Liver Disease

    Scientists explored the expression, role and mechanism of DNA damage regulated autophagy modulator 1 (DRAM1) in alcohol-related liver disease and revealed that ethanol-induced DRAM1 of hepatic cells could increase the pyruvate kinase M2 (PKM2)-enriched extracellular vesicles.

    Hif-1α-Activated Long Non-Coding RNA KDM4A-AS1 Promotes Hepatocellular Carcinoma Progression via the miR-411-5p/KPNA2/Akt Pathway

    The authors identified a novel long non-coding RNA KDM4A-AS1, which was aberrantly overexpressed in hepatocellular carcinoma (HCC) tissues, associated with unfavorable clinical features and poor prognosis of patients. KDM4A-AS1 promoted HCC cell proliferation, migration, and invasion in vitro.

    RPRD1A Stabilizes NRF2 and Aggravates HCC Progression through Competing with p62 for TRIM21 Binding

    Investigators showed that p15INK4b-related sequence/regulation of nuclear pre-mRNA domain-containing protein 1A (RPRD1A) was highly expressed in hepatocellular carcinoma (HCC) tumors and correlated with aggressive clinicopathological features.

    Identification of Gm15441, a Txnip Antisense lncRNA, as a Critical Regulator in Liver Metabolic Homeostasis

    Scientists investigated the role of Gm15441 in the regulation of thioredoxin-interacting protein (Txnip) and liver metabolism and found that the expression levels of Gm15441 and Txnip showed a similar response pattern to metabolic signals in vivo and in vitro, but that their functions were predicted to be opposite.

    Soluble CD137 Is a Novel Serum Marker of Liver Cirrhosis in Patients with Hepatitis C and Alcohol-Associated Disease Etiology

    Serum soluble CD137 (sCD137) is associated with inflammatory states, and positively correlated with serum tumor necrosis factor in cirrhotic hepatitis C virus patients following virus eradication.

    Abstract

    Hypoxia-Induced Fascin-1 Upregulation Is Regulated by Akt/Rac1 Axis and Enhances Malignant Properties of Liver Cancer Cells via Mediating Actin Cytoskeleton Rearrangement and Hippo/Yap Activation

    Investigators explored the potential functions of hypoxia-induced upregulation of Fascin-1 in liver cancer and found that Fascin-1 was upregulated by hypoxia in liver cancer cell lines, elevated in liver cancer patients and correlated with larger tumor size, lymph node metastasis, distant metastasis, and shorter overall survival.

    LncRNA LINC00667 Aggravates the Progression of Hepatocellular Carcinoma by Regulating Androgen Receptor Expression as a miRNA-130a-3p Sponge

    Scientists investigated the function and mechanism of LINC00667 in hepatocellular carcinoma progression. The effects of LINC00667 silencing in cell proliferation, cell migration, and cell invasion, and androgen receptor expression were determined with loss-of-function phenotypic analysis in Huh-7 and HCCLM3 cells.

    CircFOXM1 Promotes Proliferation and Metastasis of Hepatocellular Carcinoma via Regulating miR-1179/SPAG5 Axis

    Investigators explored the regulatory mechanism of circFOXM1 in hepatocellular carcinoma (HCC) proliferation and metastasis. RNA polymerase inhibitor actinomycin D and RNase R exonuclease were used to identify circFOXM1 in HCC cells.

    Tenofovir Disoproxil Fumarate Directly Ameliorates Liver Fibrosis by Inducing Hepatic Stellate Cell Apoptosis via Downregulation of PI3K/Akt/mTOR Signaling Pathway

    Activated hepatic stellate cell cell lines were used to evaluate the effects of tenofovir disoproxil fumarate and entecavir. After treatment with each antiviral agent, cell viability, morphology, apoptotic features, autophagy and antifibrosis signaling pathways were examined.

    Cell Membrane Breakage and Triggering T Cell Infiltration Are Involved in Human Telomerase Reverse Transcriptase (hTERT) Promoter-Driven Novel Peptide Kk-64 for Liver Cancer Gene Therapy

    Researchers designed a new peptide KK-64, and it showed strong cytotoxicity against liver cancer cells. To obtain the tumor targeting property, a plasmid that contains KK-64 DNA fragment and driven by hTERT promoter was constructed.
