BACKGROUND The mechanism of rapid growth of the residual tumor after radiofrequency (RF) ablation is poorly understood. In this study, we investigated the effect of hyperthermia on HepG2 cells and generated a subline with enhanced viability and dys-regulated angiogenesis in vivo, which was used as a model to further determine the molecular mechanism of the rapid growth of residual HCC after RF ...

Abstract In this paper, we studied the inhibitory effect of oleanolic acid (OA) on non-enzymatic glycosylation and improvement glycometabolism in insulin resistant (IR) human liver tumour (HepG2) cells. The anti-glycosylation activity OA was determined by bovine serum albumin (BSA) fructose model. results showed that moderately inhibited formation intermediates glycosylation, fructosamine ?-dic...

A new series of 1,2-diaryl-4,5,6,7-tetrahydro-1H-benzo[d]imidazoles, possessing trimethoxy phenyl pharmacophore, were synthesized to evaluate their biological activities as tubulin inhibitors. Cytotoxic activity of the synthesized compounds 7a-f was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HEPG2 (liver hepatocellular cells), A549 (adenocarcinomic h...

Previously, we characterized the biological properties of Akbu-LAAO, a novel L-amino acid oxidase from Agkistrodon blomhoffii ussurensis snake venom (SV). Current work investigated its in vitro anti-tumor activity and underlying mechanism on HepG2 cells. Akbu-LAAO inhibited HepG2 growth time and dose-dependently with an IC50 of ~38.82 μg/mL. It could induce the apoptosis of HepG2 cells. Akbu-LA...

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 ...

In an attempt to dissect the mechanism of Strychnos nux-vomica, a commonly used Chinese folk medicine in the therapy of liver cancer, the cytotoxic effects of four alkaloids in Strychnos nux-vomica, brucine, brucine N-oxide, strychnine, and isostrychnine, on human hepatoma cells (HepG2) were screened by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl-tetrasolium bromide (MTT) assay. Brucine, among th...

Augmenter of liver regeneration (ALR), which is critically important in liver regeneration and hepatocyte proliferation, is highly expressed in cirrhotic livers and hepatocellular carcinomas (HCC). In the current study, the functional role of ALR in hepatocancerogenesis was analyzed in more detail. HepG2 cells, in which the cytosolic 15 kDa ALR isoform was reexpressed stably, (HepG2-ALR) were u...

BACKGROUND Recent clinical studies have linked polymorphisms in the xeroderma pigmentosum group D (XPD) gene, a key repair gene involved in nucleotide excision repair, to increased risk of hepatocellular carcinoma (HCC). However, the cellular effects of XPD expression in cultured HCC cells remain largely uncharacterized. Therefore, the aim of this study was to characterize the in vitro cellular...

In an attempt to dissect the mechanism of Strychnos nuxvomica, a commonly used Chinese folk medicine in the therapy of liver cancer, the cytotoxic effects of four alkaloids in Strychnos nux-vomica, brucine, brucine N-oxide, strychnine, and isostrychnine, on human hepatoma cells (HepG2) were screened by 3-(4,5dimethylthiazol-2-yl)-2,5-diphenyl-tetrasolium bromide (MTT) assay. Brucine, among the ...

BACKGROUND This work demonstrates successful propagation of HCV in HepG2 and human blood cells as well as viral shedding into their culture media. The influence of Schistosoma mansoni crude soluble egg antigens (SEA) on the rate of viral propagation in both mammalian cells was also monitored. METHODOLOGY HepG2 cells were inoculated with HCV viremic human sera and some wells were exposed to HC...
