The aim of this study was to investigate the methylation status of fragile histidine triad (FHIT) and the effects of FHIT on cell growth and cyclin D1 expression in hepatoma cells. The total proteins from the human hepatoma cell lines HepG2, Hep3B and Huh7 were collected and the expression levels of FHIT were analyzed. The methylation status in the promoter region of FHIT in the hepatoma cells ...

A new compound, 1,3,7,9-tetrahydroxy-6 H-dibenzo[ b, d]pyran-6-one (1), together with 6 known compounds (2-7), was isolated from the extract of whole plants Centella asiatica. The chemical structure elucidated on basis spectroscopic and mass spectrometric analyses. All isolates were evaluated for their cytotoxicities against 4 human cancer cell lines (MCF-7, HepG2, Hela, A549). Among them, comp...

This study is to investigate the effects of decorin (DCN) on human hepatoma HepG2 cells under oxygen-glucose deprivation (OGD) condition. HepG2 cells were cultured under OGD condition. CCK-8 assay was used to assess the cell survival, and flow cytometry was performed to detect the apoptosis. Protein expression levels were detected with Western blot analysis. Transfection was performed with lipo...

Objective(s): Hepatocellular carcinoma (HCC) is one of the leading fatal neoplasms and the most common primary liver malignancy worldwide. Peptide hormone ANGPTL8 (betatrophin) may act as an important regulator in HCC development through the Wnt/β-catenin pathway. We aimed to evaluate the effects of recombinant ANGPTL8 on Wnt/β-catenin signaling in human liver carcinom...

Pregnane X receptor (PXR) mRNA was detected in HepG2 cells by RT-PCR, but not in human fetal liver (HFL) cells. CYP3A4 was induced by rifampicin (RIF), mifepristone (RU486), clotrimazole (CTZ), and dexamethasone (DEX) in HepG2 cells, while these PXR ligands with the exception of DEX did not induce CYP3A4 mRNA expression in HFL cells. Ad-PXR infection increased mRNA levels of PXR and CYP3A4 in b...

Two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. Cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HepG2 (liver hepatocellular cells), A549 (adenocarcinomic human alveolar basal epithel...

The aim of this study was to investigate the selective killing effect of the herpes simplex virus-thymidine kinase/ganciclovir (TK/GCV) suicide gene system controlled by the survivin promoter on hepatocellular carcinoma (HCC) cells in vitro. Recombinant plasmid vectors driven by the survivin promoter were constructed. HepG2 HCC and LO2 normal huma...

The treatment of cancer draws interest from researchers worldwide. Of the different extracts from traditional Chinese medicines, Tubeimoside 1 (TBMS 1) is regarded as an effective treatment for cancer. To determine the mechanism of TBMS 1, the shape/pattern of HepG2 cells based on the microscopic imaging technology was determined to analyze experimental results; then the fluorescent spectra met...
