    CircMEMO1 Modulates the Promoter Methylation and Expression of TCF21 to Regulate Hepatocellular Carcinoma Progression and Sorafenib Treatment Sensitivity

    Scientists found that circMEMO1 was significantly downregulated in hepatocellular carcinoma (HCC) samples and that the level of circMEMO1 was closely related to the OS and disease-free survival of HCC patients.

    Selective Inhibition of Cullin 3 Neddylation through Covalent Targeting DCN1 Protects Mice from Acetaminophen-Induced Liver Toxicity

    Researchers reported the discovery of DI-1548 and DI-1859 as two potent, selective and covalent DCN1 inhibitors. These inhibitors selectively inhibited neddylation of cullin 3 in cells at low nanomolar concentrations and were two-three orders of magnitude more potent than previously reported reversible DCN1 inhibitor.

    Blueberry-Derived Exosomes-Like Nanoparticles Ameliorate Nonalcoholic Fatty Liver Disease by Attenuating Mitochondrial Oxidative Stress

    Investigators found that blueberry-derived exosomes-like nanoparticles could ameliorate oxidative stress in rotenone-induced HepG2 cells and high-fat diet-fed C57BL/6 mice.

    Evaluation and Comparison of In Vitro Intrinsic Clearance Rates Measured Using Cryopreserved Hepatocytes from Humans, Rats, and Rainbow Trout

    Cryopreserved hepatocytes from humans, rats, and rainbow trout were used to measure CLint values for 54 industrial and pesticidal chemicals at starting test concentrations of 0.1 and 1 µM.

    TFB2M Activates Aerobic Glycolysis in Hepatocellular Carcinoma Cells through the NAD+/SIRT3/HIF-1α Signaling

    Researchers found that mitochondrial transcription factor B2 (TFBM2) promoted the progression of hepatocellular carcinoma cells through HIF‐1α‐regulated reprogramming of glucose metabolism.

    LY-294002 Enhances the Chemosensitivity of Liver Cancer to Oxaliplatin by Blocking the PI3K/AKT/HIF-1α Pathway

    Scientists investigated the effects of the PI3K inhibitor LY‑294002 and AKT inhibitor MK2206 on the chemosensitivity of oxaliplatin‑resistant liver cancer cells and the molecular mechanism involved.

    Mechanisms and Disease Consequences of Nonalcoholic Fatty Liver Disease

    Investigators provide an in-depth discussion of the underlying pathogenetic mechanisms that lead to progressive liver injury, including the metabolic origins of nonalcoholic fatty liver disease (NAFLD), the effect of NAFLD on hepatic glucose and lipid metabolism, bile acid toxicity, macrophage dysfunction, and hepatic stellate cell activation, and consider the role of genetic, epigenetic, and environmental factors that promote fibrosis progression and risk of hepatocellular carcinoma in nonalcoholic steatohepatitis.

    Regulation and Functional Roles of Chemokines in Liver Diseases

    Scientists provide an overview of chemokine biology, with a particular focus on the genetic and epigenetic regulation of chemokine transcription as well as on the cell type-specific production of chemokines by liver cells and liver-associated immune cells.
