    Hepatocyte CYR61 Polarizes Profibrotic Macrophages to Orchestrate NASH Fibrosis

    Cysteine-rich angiogenic inducer 61 (CYR61) liver-specific knockout mice on a nonalcoholic steatohepatitis (NASH) diet showed improved glucose tolerance, decreased liver inflammation, and reduced fibrosis.
    [Science Translational Medicine]

    Secreted Folate Receptor γ Drives Fibrogenesis in Metabolic Dysfunction–Associated Steatohepatitis by Amplifying TGFβ Signaling in Hepatic Stellate Cells

    Scientists identified that soluble folate receptor γ was a secreted protein that was elevated in the livers of patients with metabolic dysfunction–associated steatohepatitis.

    Abstract

    Metabolic Crosstalk between Skeletal Muscle Cells and Liver through IRF4-FSTL1 in Nonalcoholic Steatohepatitis

    The authors elucidated an endocrine pathway that was regulated by skeletal muscle interferon regulatory factor 4 (IRF 4), which manipulated liver pathology.

    Targeting LINC01607 Sensitizes Hepatocellular Carcinoma to Lenvatinib via Suppressing Mitophagy

    Researchers identified inhibition of reactive oxygen species levels and reduced redox status in Lenvatinib-resistant HCC. Integrating RNA-seq with unbiased whole-genome CRISPR-Cas9 screen analysis indicated LINC01607 regulated the P62 to enhance drug resistance by affecting mitophagy and antioxidant pathways.

    CRY1/2 Regulate Rhythmic CYP2A5 in Mouse Liver through Repression of E4BP4

    Scientists investigated a potential role of CRY1/2 in circadian regulation of hepatic cytochromes P450 (CYP) 2A5. Regulatory effects of CRY1/2 on CYP2A5 were determined using cryptochrome 1 (Cry1)-null and Cry2-null mice, and validated using AML-12, Hepa1-6, and HepG2 cells.

    4EBP2-Regulated Protein Translation Has a Critical Role in High-Fat-Diet-Induced Insulin Resistance in Hepatocytes

    The authors mapped the phosphorylation rewiring events in palmitic acid (PA)-stimulated HepG2 cells and found PA decreased the phosphorylation level of the eukaryotic translation initiation factor 4E-binding protein 4EBP2 at S65/T70.

    Tex10 Interacts with STAT3 to Regulate Hepatocellular Carcinoma Growth and Metastasis

    The expression of testis expression 10 (Tex10) in the HCC cell line and tissue microarray was determined by Western blot and immunohistochemistry, respectively.

    Abstract

    Gas7 Attenuates Hepatocellular Carcinoma Progression and Chemoresistance through the PI3K/Akt Signaling Pathway

    Researchers revealed that growth arrest-specific gene 7 (Gas7) was downregulated in various HCC cell lines and low Gas7 expression was associated with decreased overall survival in patients with HCC.
    [Cellular Signalling]

    Abstract

    ROR1-AS1 Might Promote In Vivo and In Vitro Proliferation and Invasion of Cholangiocarcinoma Cells

    Investigators assessed cell viability, proliferation, invasion, and migration using three cell lines to explore the biological characteristics of receptor-tyrosine-kinase-like orphan receptor-1 antisense 1 (ROR1-AS1) in cholangiocarcinoma.

    Found in Translation—Fibrosis in Metabolic Dysfunction–Associated Steatohepatitis (MASH)

    Recent advances in single-cell methodologies, refined disease models, and genetic and epigenetic insights have provided a nuanced understanding of MASH fibrogenesis, with substantial cellular heterogeneity in MASH livers providing potentially targetable cell-cell interactions and behavior.
    [Science Translational Medicine]

    Abstract

    Contemporary Applications of Y90 for the Treatment of Hepatocellular Carcinoma

    The potential synergy between transarterial radioembolization and immunotherapy has been recognized, and prospective studies evaluating this combination are needed for patients with Barcelona Clinic Liver Cancer B and C HCC.
