    Dissecting Spatial Heterogeneity and the Immune-Evasion Mechanism of CTCs by Single-Cell RNA-Seq in Hepatocellular Carcinoma

    Scientists revealed that the transcriptional dynamics of circulating tumor cells were associated with stress response, cell cycle and immune-evasion signaling during hematogeneous transportation.

    Hepatocyte Membrane Potential Regulates Serum Insulin and Insulin Sensitivity by Altering Hepatic GABA Release

    Researchers established that hepatocyte depolarization depressed hepatic afferent vagal nerve firing, increased GABA release from liver slices, and caused hyperinsulinemia.

    Metabolic Characterization of a Potent Natural Neuroprotective Agent Dendrobine In Vitro and in Rats

    Scientists investigated the metabolic characteristics of dendrobine in vitro and in rats. The metabolic stability and temporal profile of metabolites formation of dendrobine were assayed in human/rat liver microsomal and S9 fractions.

    Abstract

    Novel CDK9 Inhibitor Oroxylin a Promotes Wild-Type P53 Stability and Prevents Hepatocellular Carcinoma Progression by Disrupting Both MDM2 and SIRT1 Signaling

    Researchers demonstrated that CDK9 was closely associated with the progression of hepatocellular carcinoma (HCC) and could serve as an HCC therapeutic target by modulating the recovery of wild-type p53 function.

    Abstract

    Proteomic Profiling of Murine Biliary-Derived Hepatic Organoids and Their Capacity for Drug Disposition, Bioactivation and Detoxification

    Differentiation of organoids significantly increased the expression of multiple cytochrome P450, phase II enzymes, liver biomarkers and hepatic transporters. The differentiated organoids were shown to exhibit increased sensitivity to midazolam and irinotecan, when compared to the undifferentiated organoids.

    Tumor Microenvironment Alters Chemoresistance of Hepatocellular Carcinoma through CYP3A4 Metabolic Activity

    Investigators utilized four common hepatocellular carcinoma (HCC) cell lines embedded in 3D collagen type-I gels of varying stiffnesses to mimic normal and cirrhotic livers with environmental oxygen regulation to quantify the impact of these microenvironmental factors on HCC chemoresistance.

    Auranofin Prevents Liver Fibrosis by System Xc-Mediated Inhibition of NLRP3 Inflammasome

    The antifibrotic effect of auranofin was assessed in thioacetamide- and carbon tetrachloride-induced liver fibrosis models. Hepatic stellate cells, bone marrow-derived macrophages, kupffer cells, and hepatocyte were used to examine the underlying mechanism of auranofin.

    The Mechanism of Increased Intestinal Palmitic Acid Absorption and Its Impact on Hepatic Stellate Cell Activation in Nonalcoholic Steatohepatitis

    Researchers clarified the intestinal absorption kinetics of dietary palmitic acid (PA) and the effect of trans-portal PA on the activation of hepatic stellate cells involved in liver fibrosis in nonalcoholic steatohepatitis.

    Validation of an Adipose-Liver Human-on-a-Chip Model of NAFLD for Preclinical Therapeutic Efficacy Evaluation

    Investigators developed a human-on-a-chip model composed of human hepatocytes and adipose tissue chambers capable of modeling the metabolic factors that contribute to liver disease development and progression, and evaluation of the therapeutic metformin.

    Abstract

    Molecular and Pathobiological Involvement of Fetuin-A in the Pathogenesis of NAFLD

    The authors review the various molecular pathways, and genetic relevance of mRNA expression of fetuin-A which is correlated with progression of non-alcoholic fatty liver disease (NAFLD).
