    Single-Cell Analysis of Hepatoblastoma Identifies Tumor Signatures That Predict Chemotherapy Susceptibility Using Patient-Specific Tumor Spheroids

    Scientists used single-cell transcriptomic techniques to analyze resected human pediatric hepatoblastoma specimens, and identified five hepatoblastoma tumor signatures that may have accounted for the tumor heterogeneity observed in this disease.

    Isoginkgetin, a Potential CDK6 Inhibitor, Suppresses SLC2A1/GLUT1 Enhancer Activity to Induce AMPK-ULK1-Mediated Cytotoxic Autophagy in Hepatocellular Carcinoma

    Investigators revealed that isoginkgetin (ISO) effectively inhibited HCC proliferation and migration in vitro. LC3-II expression and autophagosomes were increased under ISO treatment.

    Abstract

    Inhibition of EGFR Overcomes Acquired Lenvatinib Resistance Driven by STAT3-ABCB1 Signaling in Hepatocellular Carcinoma

    ATP-binding cassette transporter B1 (ABCB1) was activated by epidermal growth factor receptor (EGFR) in a lipid raft-dependent manner, which enhanced the exocytosis of lenvatinib to mediate resistance.

    Abstract

    Extended-Synaptotagmin 1 Engages in Unconventional Protein Secretion Mediated via SEC22B+ Vesicle Pathway in Liver Cancer

    The authors investigated the identification of extended-synaptotagmin 1, an endoplasmic reticulum (ER)-bound protein, as a key mediator for cytosolic protein secretion at the ER–plasma membrane contact sites.

    Abstract

    Regulating Nrf2-GPx4 Axis by Bicyclol Can Prevent Ferroptosis in Carbon Tetrachloride-Induced Acute Liver Injury in Mice

    Erastin-treated L-O2 hepatocytes were transfected with glutathione peroxidase 4 (GPx4) or nuclear factor erythroid 2-related factor 2 (Nrf2) siRNA to delineate the pathway of bicyclol against ferroptosis in vitro.
