    An Endoplasmic Reticulum Stress‐MicroRNA‐26a Feedback Circuit in Nonalcoholic Fatty Liver Disease

    Scientists identified a negative feedback loop comprising hepatic endoplasmic reticulum (ER) stress and micro RNA (miRNA)‐26a in nonalcoholic fatty liver disease pathogenesis. Combining miRNA dot blot array and quantitative PCR, they found that miR‐26a was specifically induced by ER stress in liver cells.

    The miR-92a-2-5p in Exosomes from Macrophages Increases Liver Cancer Cells Invasion via Altering the Ar/Phlpp/P-Akt/β-Catenin Signaling

    Mechanism dissection revealed that miR-92a-2-5p from the exosomes could target the 3′UTR of androgen receptor (AR) mRNA to suppress AR translation, altering the PHLPP/p-AKT/β-catenin signaling to increase liver cancer cells invasion.

    Regulation of Hepatic Differentiation of Human Embryonic Stem Cells by Calcium Silicate Extracts for Liver Injury Repairing

    The roles of calcium silicate (CS)-activated H9 cells in liver injury repair were tested by cell tracking and immunohistochemical staining. Results indicated that high concentrations of CS extracts initially enhanced definitive endodermal (DE) lineage, followed by gradual DE differentiation at low CS concentrations.

    Abstract

    The Role of Bone Morphogenetic Protein Signaling in Non-Alcoholic Fatty Liver Disease

    Treatment with either of two bone morphogenetic protein (BMP) inhibitors reduced hepatic triglyceride content in diabetic mice. BMP inhibitor-induced decrease in hepatic triglyceride levels were associated with decreased mRNA encoding Dgat2, an enzyme integral to triglyceride synthesis.

    Transcriptional Regulation of the Angptl8 Gene by Hepatocyte Nuclear Factor-1 in the Murine Liver

    Mutation of the hepatocyte nuclear factor (HNF)-1 binding site significantly decreased the promoter activity in hepatocytes, and the promoter carrying the mutated HNF-1 site was not transactivated by co-transfection of HNF-1 in a non-hepatic cell line.

    IFN-α-2b Induces Apoptosis by Decreasing Cellular Cholesterol Levels in Rat Preneoplastic Hepatocytes

    Using in vitro and in vivo approaches, the authors evaluated apoptosis and lipid metabolism. IFN-α-2b induced changes in hepatic cholesterol mass due to decreased synthesis and increased secretion.

    Study on the Relationship between Hepatic Fibrosis and Epithelial-Mesenchymal Transition in Intrahepatic Cells

    Researchers explored the relationship between the relevant regulatory factors and the epithelial-mesenchymal transition signaling pathways in the various intrahepatic cells.

    Combination of Luteolin and Lycopene Effectively Protect against the “Two-Hit” in NAFLD through Sirt1/AMPK Signal Pathway

    Scientists found that luteolin (20 μM) + lycopene (10 μM) was the best therapeutic combination in sodium palmitate (PA)-induced HepG2 cells, and significantly improved cell viability and lipid accumulation in PA-induced HepG2 cells and primary hepatocytes.

    PD173074 Blocks G1/S Transition via CUL3-Mediated Ubiquitin Protease in HepG2 and Hep3B Cells

    Researchers found fibroblast growth factor receptor 4 (FGFR4) was overexpressed in hepatocellular carcinoma cell lines HepG2 and Hep3B. They used PD173074, an FGFR4 inhibitor, to explore the role of FGFR4 and its underlying mechanism in these cell lines.

    The Role of MDM2–p53 Axis Dysfunction in the Hepatocellular Carcinoma Transformation

    The authors focus on the current studies of the MDM2–p53 axis in hepatocellular carcinoma, and specifically discuss the impact of MDM2–p53 axis dysfunction by viral infection and metabolic disease in the transformation of normal hepatocytes into hepatoma cells.

    NIH’s New Sexual-Harassment Rules Are Still Too Weak, Say Critics

    On 24 June, the US National Institutes of Health (NIH) described the actions it will take when alerted to reports of unsafe behaviour, including restricting scientists from peer-review panels, holding back pending grants and refusing university requests to transfer funding to other institutions in cases where a harasser changes jobs.
