    Interferon Lambda Receptor-1 Isoforms Differentially Influence Gene Expression and HBV Replication in Stem Cell-Derived Hepatocytes

    Induced pluripotent stem-cell-derived hepatocytes engineered to contain FLAG-tagged, doxycycline-inducible IFNLR1 isoform constructs were HBV-infected and then treated with IFNL3 followed by assessment of gene expression, HBV replication, and cellular viability.

    AbstractGraphical Abstract

    Single-Cell Transcriptome Sequencing Reveals Spatial Distribution of IL34+ Cancer-Associated Fibroblasts in Hepatocellular Carcinoma Tumor Microenvironment

    Scientists acquired scRNA-seq datasets about HCC, which enabled them to identify distinct cell subpopulations within HCC tissues. They conducted a differential analysis to pinpoint DEGs associated with normal fibroblasts and cancer-associated fibroblasts.

    Gp78 Deficiency in Hepatocytes Alleviates Hepatic Ischemia-Reperfusion Injury via Suppressing ACSL4-Mediated Ferroptosis

    Hepatocyte-specific gp78 knockout or overexpressed mice were generated to examine the effect of gp78 on liver ischemia-reperfusion injury, and a multi-omics approach was performed to explore the potential mechanism.

    C–C Chemokine Receptor 5 Is Essential for Conventional NK Cell Trafficking and Liver Injury in a Murine Hepatitis Virus-Induced Fulminant Hepatic Failure Model

    Scientists investigated the potential therapeutic role of chemokine receptors in the migration of natural killer cells in a murine hepatitis virus strain 3-induced fulminant hepatic failure model and its mechanism.

    SPRTN Is Involved in Hepatocellular Carcinoma Development through the ER Stress Response

    Researchers analyzed SPRTN and UPR in 21 human HCC tissue samples using RT-qPCR, immunoblot, and immunohistochemistry. They found alterations in the expression levels of SPRTN and UPR-related genes and proteins in HCC samples.

    Abstract

    BMAL1 Deletion Protects against Obesity and Non-Alcoholic Fatty Liver Disease Induced by a High-Fat Diet

    Investigators explored the role of brain and muscle aryl hydrocarbon receptor nuclear translocator-like1 (BMAL1), a circadian clock regulator, in the development of obesity and non-alcoholic fatty liver disease.

    Abstract

    Combination of Melt-Electrospun Poly-ε-Caprolactone Scaffolds and Hepatocyte-Like Cells from Footprint-Free hiPSCs to Create 3D Biohybrid Constructs for Liver Tissue Engineering

    3D biohybrid constructs were created by combining hepatocyte-like cells derived from patient-specific footprint-free human induced pluripotent stem cells and 3D melt-electrospun poly-ε-caprolactone scaffolds.

    Construction of a ceRNA Regulatory Network to Explore Potential Pathogenesis Mechanisms Involved in Human Hepatocellular Carcinoma

    Transcriptional profile analysis was used to analyze expression of circRNAs in HCC in this study. The top ten upregulated circRNAs were selected and validated by quantitative reverse transcription polymerase chain reaction in another 34 HCC patients.
