In the present study, we investigated the antitumor effects of Smh-3 on the viability, cell cycle and apoptotic cell death in human hepatocellular carcinoma Hep3B cells in vitro. We also investigated the molecular mechanisms involved in the effects of Smh-3 on human hepatoma Hep3B cells, including the effects on protein and mRNA levels which were determined by western blotting and DNA microarra...

Objective(s): In the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (EGCG) on lipopolysaccharide (LPS)-induced hepatotoxicity by using Hep3B human hepatoma cells. Specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of LPS-associated cytotoxicity. Consequently, the hepatocellu...

In several reports, the respiratory syncytial virus (RSV) was identified as an oncolytic virus in cancer cells (e.g., lung and prostate cancer). However, the effects of RSV in hepatocellular carcinoma (HCC) cells have not yet been investigated. Here, we observed the inhibitory effects of RSV infection in HCC cell-lines. Cell growth was significantly decreased by RSV infection in BNL-HCC, Hep3B,...

Erythropoietin (€PO) gene transcription is activated in kidney cells in vivo and in Hep3B cells exposed to hypoxia or cobalt chloride. Hypoxia-inducible factor 1 (HIF-1) is a nuclear factor that binds to the hypoxia-inducible enhancer of the €PO gene at a site that is required for transcriptional activation. HIF-1 DNA-binding activity is induced by hypoxia or cobalt chloride treatment of Hep3B ...

As the main source of extracellular matrix proteins in tumor stroma, hepatic stellate cells (HSCs) have a great impact on biological behaviors of hepatocellular carcinoma (HCC). In the present study, we have investigated a mechanism whereby HSCs modulate the chemoresistance of hepatoma cells. We used human HSC line lx-2 and chemotherapeutic agent cisplatin to investigate their effects on human ...

A new flavonol glycoside derivate named kaempferol 3- O- trans- p-coumaroyl-7- α-ʟ-rhamnoside (1), together with five known compounds (2–6), was isolated from the EtOAc-soluble extract of leaves Tripterygium wilfordii. The structure compound elucidated spectroscopic and physico-chemical analyses. All isolates were evaluated for in vitro cytotoxic activity against four human cancer cells includi...

objective(s): in the present study, our aim was to investigate the possible protective effects of epigallocatechin gallate (egcg) on lipopolysaccharide (lps)-induced hepatotoxicity by using hep3b human hepatoma cells. specifically, the study examines the role of some proinflammatory markers and oxidative damage as possible mechanisms of lps-associated cytotoxicity. consequently, the hepatocellu...

The anticancer activities of gambogic acid (GA) on two hepatocellular carcinoma cells with either p53 deletion (Hep3B) or p53 mutation (Huh7) were investigated in the present study. GA inhibited the growth of Hep3B and Huh7 through similar apoptotic pathways. After treatment of Hep3B and Huh7 with GA for 24 h, the IC₅₀ was determined for both cell lines at 1.8 and 2.2 µM, respectively. The resu...

Previous studies reported that a Gamitrinib variant containing triphenylphosphonium (G-TPP) binds to mitochondrial Hsp90 and rapidly inhibits its activity to induce apoptosis. We investigated the mechanisms underlying the antitumor activity of G-TPP in Hep3B hepatocellular carcinoma cells. Contrary to our predictions, we observed mitochondrial elongation in the G-TPP-treated Hep3B cells undergo...

PMA has both mitogenic and antiproliferative effects on human hepatoma Hep3B cells. In response to low PMA concentration (10 nM), Hep3B cells displayed an increasing proliferation potentiation. At high PMA concentration (1 microM) Hep3B cells exhibited modest cytostatic effects. Determinations of protein kinase C (PKC) activity in PMA-treated cells revealed that alterations in PKC activity are ...
