Sirt6 Alleviated Liver Fibrosis by Deacetylating Conserved Lysine 54 on Smad2 in Hepatic Stellate Cells

Scientists aimed to elucidate the role of the deacetylase Sirt6 in hepatic stellate cell (HSC) activation and liver fibrosis. Gain‐ and loss‐of‐function models were used to study the function of Sirt6 in HSC activation.

Hepatic HuR Modulates Lipid Homeostasis in Response to High-Fat Diet

Hepatocyte-specific HuR knockout reduced the expression of APOB, UQCRB, and NDUFB6 in mice, reducing liver lipid transport and ATP synthesis, and aggravating high-fat diet-induced non-alcoholic fatty liver disease.

Aging Suppresses Sphingosine-1-Phosphate Chaperone ApoM in Circulation Resulting in Maladaptive Organ Repair

Investigators showed that the liver-derived apolipoprotein M (ApoM) protected the lung and kidney from pro-fibrotic insults and that this circulating factor was attenuated in aged mice. Aged mouse hepatocytes exhibited transcriptional suppression of ApoM.

Roseotoxin B Alleviates Cholestatic Liver Fibrosis through Inhibiting PDGF-B/PDGFR-β Pathway in Hepatic Stellate Cells

Roseotoxin B was shown to possess an improving effect on cholestatic liver fibrosis in bile duct-ligated mice, as proved by histochemical and immunohistochemical staining, hepatic biochemical parameters, and TUNEL apoptotic cell detection in tissue sections.

Hydrazinocurcumin and 5-Fluorouracil Enhance Apoptosis and Restrain Tumorigenicity of HepG2 Cells via Disrupting the PTEN-Mediated PI3K/Akt Signaling Pathway

Scientists investigated the role and mechanism of hydrazinocurcumin (HZC) in regulating HepG2 cell apoptosis and tumorigenicity, and its synergistic effects with 5-fluorouracil (5-Fu). HepG2 cells were treated with HZC and/or 5-Fu to analyze the possible synergistic effects on cell proliferation, apoptosis and cell cycle distribution in vitro using EdU staining.

SOX9 Enhances Sorafenib Resistance through Upregulating ABCG2 Expression in Hepatocellular Carcinoma

The authors found that sorafenib treatment increased the proportion of SOX9 positive cells in hepatocellular carcinoma (HCC) cell lines. Overexpression of exogenous SOX9 in HCC increased sorafenib resistance both in vitro and in vivo, whereas down-regulation led to inhibition of sorafenib resistance.

Asiatic Acid Ameliorates Acute Hepatic Injury by Reducing Endoplasmic Reticulum Stress and Triggering Hepatocyte Autophagy

Researchers investigated the effects and underlying mechanisms of Asiatic acid from Potentilla chinensis on acute liver injury (ALI). The model of ALI in mice was induced by administration with Lipopolysaccharide/D-Galactosamine.

Astaxanthin Inhibits the Reduction of Glycolysis during the Activation of Hepatic Stellate Cells

Compared with quiescent hepatic stellate cells (HSCs), activated HSCs (aHSCs) had significantly lower expression of glucose transporter 1, the major glucose transporter in HSCs, and its transcription factor hypoxia-inducible factor 1α, which was markedly increased by astaxanthin in aHSCs.

Abstract

Anti-Inflammatory, Hepatoprotective and Antioxidant Activity of Ellagitannin Isolated from Melaleuca styphelioides

The hepatoprotective activity of styphelioidin was tested using the CCl4-challenged HepG2 cell model by measuring alanine aminotransferase and aspartate aminotransferase levels in HepG2 cells treated with styphelioidin for one hour followed by 40 mM CCl4.

MicroRNA200a Enhances Antitumor Effects in Combination with Doxorubicin in Hepatocellular Carcinoma

Scientists investigated the effects of specific microRNA-200a (miR-200a) on hepatocellular carcinoma (HCC) tumor cell growth and effect of doxorubicin-mediated cytotoxicity. Their results showed miR-200a to be downregulated in human HCC and HCC tumor cell lines.
