    p53 Positively Regulates the Proliferation of Hepatic Progenitor Cells Promoted by Laminin-521

    The authors showed that p53 expression increased gradually and reached maximal levels around eight days when laminin α4, α5, β2, β1, and γ1 subunit levels also reached a maximum during hepatic progenitor cell activation and expansion.

    Arid1a Mutation Suppresses TGF-β Signaling and Induces Cholangiocarcinoma

    Using cultured cells, researchers found that Arid1a loss caused cellular proliferation, escape from cell-cycle control, senescence, and widespread changes in chromatin structure.

    Hepatocyte-Specific Prominin-1 Protects against Liver Injury-Induced Fibrosis by Stabilizing SMAD7

    To understand the role of hepatocellular PROM1 in liver fibrosis, global and liver-specific Prom1-deficient mice were analyzed after bile duct ligation. Investigators found that PROM1 was upregulated in the plasma membrane of fibrotic hepatocytes.

    High Level of Polarized Engraftment of Porcine Intrahepatic Cholangiocyte Organoids in Decellularized Liver Scaffolds

    Researchers generated porcine intrahepatic cholangiocyte organoids from adult stem cells and demonstrated that these cultures remained stable over multiple passages whilst retaining the ability to differentiate into hepatocyte- and cholangiocyte-like cells.

    Corosolic Acid Sensitizes Ferroptosis by Upregulating HERPUD1 in Liver Cancer Cells

    The authors found that corosolic acid could inhibit glutathione synthesis (GSH) via HERPUD1, decreasing the cellular GSH level and causing liver cancer cells to become more sensitive to ferroptosis.

    Long Non-Coding RNA SNHG6 Couples Cholesterol Sensing with mTORC1 Activation in Hepatocellular Carcinoma

    Investigators reported that the long non-coding RNA SNHG6 increased progression from non-alcoholic fatty liver disease to HCC by modulating cholesterol-induced mTORC1 activation.

    Health Disparities in Chronic Liver Disease

    The authors review the existing literature on racial and ethnic, gender, and socioeconomic disparities in chronic liver diseases using a social determinants of health framework to better understand how social and structural factors cause health disparities and affect chronic liver disease outcomes.
