    TOP STORY

    Short-Term Tamoxifen Administration Improves Hepatic Steatosis and Glucose Intolerance through JNK/MAPK in Mice

    Researchers conducted in vitro experiments and found that tamoxifen protected hepatocytes against sodium palmitate-induced lipotoxicity.

    Multi-Targeted Peptide-Modified Gold Nanoclusters for Treating Solid Tumors in the Liver

    The authors designed amphiphilic peptide-modified glutathione-gold nanocluster aggregates with the enrichment of solid liver tumors and the prolonged stress in the endoplasmic reticulum.

    Abstract

    Alcohol-Induced Extracellular Asc Specks Perpetuate Liver Inflammation and Damage in Alcoholic Hepatitis Even after Alcohol Cessation

    Researchers showed that while chronic alcohol-induced NLRP3 inflammasome activation in the liver, alcohol binge resulted not only in NLRP3 inflammasome activation but also in increased circulating extracellular ASC specks and hepatic ASC aggregates.

    AbstractGraphical Abstract

    p53 Protects against Alcoholic Fatty Liver Disease via ALDH2 Inhibition

    Scientists showed the role of p53 in regulating ethanol metabolism via acetaldehyde dehydrogenase 2 (ALDH2), a key enzyme responsible for the oxidization of alcohol.
    [EMBO Journal]

    AbstractGraphical Abstract

    ROCK Inhibition Enhanced Hepatocyte Liver Engraftment by Retaining Membrane CD59 and Attenuating Complement Activation

    Researchers found that ROCK (Rho-associated kinase) inhibitors significantly enhanced in vivo hepatocyte engraftment. Mechanistic studies suggested that the isolation of hepatocytes caused substantial degradation of cell membrane proteins.

    AbstractGraphical Abstract

    Necroptosis of Macrophage Is a Key Pathological Feature in Biliary Atresia via GDCA/S1PR2/ZBP1/P-MLKL Axis

    Investigators determined the effect of macrophage necroptosis in biliary atresia (BA) pathology and explored the specific molecular mechanism. They found that necroptosis existed in BA livers, which occurred in liver macrophages.

    SIRT3-Dependent Delactylation of Cyclin E2 Prevents Hepatocellular Carcinoma Growth

    The authors reported that SIRT3 could delactylate non-histone proteins and suppress HCC development. Using SILAC-based quantitative proteomics, they identified cyclin E2 as one of the lactylated substrates of SIRT3 in HCC cells.
    [EMBO Reports]

    AbstractGraphical Abstract

    Melatonin Modulates the Warburg Effect and Alters the Morphology of Hepatocellular Carcinoma Cell Line Resulting in Reduced Viability and Migratory Potential

    Investigators evaluated the effects of melatonin on cell cytotoxicity and proliferation, colony formation, morphological and immunohistochemical aspects, and on glucose consumption and lactate release.

    AbstractGraphical Abstract

    Ribonucleotide Reductase Subunit Switching in Hepatoblastoma Drug Response and Relapse

    Scientists found ribonucleotide reductase subunit M2 (RRM2) was one of the key genes supporting cell proliferation in high-risk hepatoblastoma.
    [Communications Biology]

    Hepatic ZBTB22-Mediated Detoxification Ameliorates Acetaminophen-Induced Liver Injury by Inhibiting Pregnane X Receptor Signaling

    Investigators explored the role of hepatic Zinc Finger And BTB Domain Containing 22 (ZBTB22) in defense against Acetaminophen-mediated hepatotoxicity.

    Dual Targets of Lethal Apoptosis and Protective Autophagy in Liver Cancer with Periplocymarin Elicit a Limited Therapeutic Effect

    Researchers demonstrated that periplocymarin synchronously activated lethal apoptosis and protective autophagy in liver cancer, and the initiation of autophagy counteracted the inherent pro‑apoptotic capacity and impaired the anti‑cancer effects.

    REVIEWS

    Primary Sclerosing Cholangitis and Overlap Features of Autoimmune Hepatitis: A Coming of Age or an Age-Ist Problem?

    Investigators discuss the concept that autoimmune sclerosing cholangitis and primary sclerosing cholangitis (PSC)/autoimmune hepatitis-overlap are not distinct entities. Rather, they represent inflammatory phases of PSC frequently manifesting earlier in disease course.

    Combinatorial Targeting of Immune Checkpoints and Epigenetic Regulators for Hepatocellular Carcinoma Therapy

    Scientists outline current immune checkpoint inhibitors (ICI) treatments for HCC and how ICIs can be combined with distinct epigenetic inhibitors to increase the durability of ICIs and potentially treat “immune-cold” HCC.
    [Oncogene]

    Abstract

    The Role of Pyroptosis in Hepatocellular Carcinoma

    The authors discuss the pyroptosis pathways and pyroptosis-related components, as well as the role of pyroptosis and its components in HCC. Finally, they review the therapeutic significance of pyroptosis in HCC.

    Abstract
    INDUSTRY AND POLICY NEWS

    Cancer Will Cost the World $25 Trillion over Next 30 Years

    The total cost of cancer to the global economy will reach 25.2 trillion international dollars between 2020 and 2050, according to an analysis of 29 cancers across 204 countries.
