    The Mitochondrial Fusion Protein OPA1 Is Dispensable in the Liver and Its Absence Induces Mitohormesis to Protect Liver from Drug-Induced Injury

    Researchers showed that optic atrophy 1 (OPA1) was required for proper complex V assembly and that OPA1 liver knockout protected the liver from drug toxicity.

    Broad-Spectrum Kinome Profiling Identifies CDK6 Upregulation as a Driver of Lenvatinib Resistance in Hepatocellular Carcinoma

    Scientists employed a lysine-targeted sulfonyl fluoride probe, named XO44, which bound to 133 endogenous kinases in intact lenvatinib-resistant HCC cells.

    Etiology-Independent Activation of the LTβ-LTβR-RELB Axis Drives Aggressiveness and Predicts Poor Prognosis in Hepatocellular Carcinoma

    Four human HCC cohorts and four mouse HCC models were assessed for expression and localization of nuclear factor kappa B signaling components and activating ligands.

    Circular RNA cFAM210A, Degradable by HBx, Inhibits HCC Tumorigenesis by Suppressing YBX1 Transactivation

    Investigators found that cFAM210A could be silenced by hepatitis B protein x (HBx). cFAM210A expression was downregulated and negatively correlated with tumorigenesis in patients with hepatitis B virus-related HCC.

    Lactobacillus plantarum Ameliorates NASH-Related Inflammation by Upregulating L-Arginine Production

    The authors used a choline-deficient high-fat diet-induced murine model and investigated the effect of L. plantarum on nonalcoholic steatohepatitis (NASH) pathogenesis using transcriptomic, metagenomic, and immunohistochemistry analyses.

    Decreased B4GALT1 Promotes Hepatocellular Carcinoma Cell Invasiveness by Regulating the Laminin-Integrin Pathway

    Investigators found that Beta1,4-galactosyltransferase (B4GALT) 1 was significantly downregulated in HCC tissue compared with the adjacent liver tissue, and low B4GALT1 expression was associated with vascular invasion and poor overall survival in patients with HCC.

    High Fat Diet-Induced Downregulation of TRPV2 Mediates Hepatic Steatosis via p21 Signaling

    Investigators reported that high-fat diet feeding induced hepatic steatosis in mice, which was accompanied by a reduction in the expression and function of hepatic TRPV2.

    Abstract

    PPARα Activation Promotes Liver Progenitor Cell-Mediated Liver Regeneration by Suppressing YAP Signaling in Zebrafish

    Using the zebrafish model of liver progenitor cell (LPC)-mediated liver regeneration, scientists presented that peroxisome proliferator-activated receptor-alpha (PPARα) activation augmented LPC-to-hepatocyte differentiation.

    Diet-Induced Rewiring of the Wnt Gene Regulatory Network Connects Aberrant Splicing to Fatty Liver and Liver Cancer in DIAMOND Mice

    The authors investigated the regulatory and transcriptional landscape in fatty livers and liver tumors from DIAMOND mice that faithfully mimicked human HCC development in the context of metabolic associated fatty liver disease.

    The Prothrombotic Tendency of Metabolic-Associated Fatty Liver Disease

    Investigators review the safety and efficacy of anticoagulation in advanced liver disease and consider whether antithrombotic agents could slow or halt the progression of fibrosis in metabolic-associated fatty liver disease.

    NSF-Funded Research to Study Liver Regeneration in Space Will Fly on SpaceX CRS-29

    To better understand the mechanisms behind the decline of liver regeneration in the elderly, researchers from the University of California, San Francisco will send tissue chips containing liver cells and immune cells to space.
