objective: a number of studies have demonstrated the potential antitumor effects of saffron and its constituents on different malignant cells in vitro. it has been reported that a novel glycoconjugate isolated from corms and callus of saffron possesses cytotoxic activity against different tumor cellswith nitric oxide (no) production. these data suggest that the cytotoxic effect of saffron extra...
background: erythropoietin (epo) is a glycoprotein hormone function to regulate the production of red blood cells. deficiency of epo is known to cause anemia in chronically infected renal patients and they require regular blood transfusion. availability of recombinant epo has eliminated the need for blood transfusion and now it is extensively used for the treatment of anemia. glycosylation of e...
Primary human hepatocytes (PHH) are a main instrument in drug metabolism research and in the prediction of drug-induced phase I/II enzyme induction in humans. The HepG2 liver-derived cell line is commonly used as a surrogate for human hepatocytes, but its use in absorption, distribution, metabolism, and excretion and toxicity studies can be limited because of lowered basal levels of metabolizin...
Recent researches have demonstrated improved survival in oncologic patients treated with low molecular weight heparins (LMWHs) which are anticoagulant drugs. We evaluated "second generation" LMWH bemiparin and its in vitro anti-tumor effects on HepG2 hepatocellular carcinoma and MIA PaCa-2 cancer cells. The aim of the study is to investigate anti-cancer mechanism of bemiparin in HepG2 and Mia-P...
Five flavonoid glycosides were isolated from the n-butanol soluble fraction of the ethanolic extract of Rapistrum rugosum and their structures were assigned from 1H- and 13C-NMR spectra (DEPT) with 2D NMR as quercetin-3-O-α-L-rhamnopyranoside (1), quercetin-3-O-β-D-xyloside (2), quercetin, 3-O-α-L-arabinopyranoside,7-O-α-L-rhamnopyranoside (3), kaempferol 3-O-α-L-arabinopyranoside, 7-O-α-L-rham...
abstract cancer is the leading cause of death worldwide. current anticancer drugs involve various toxic side effects; efforts are ongoing to develop new anticancer agents especially from the screening of natural compounds. present study investigated cytotoxic effects and mode of cell death induced by the caspian cobra venom in some human cancer cell lines. cytotoxic effects of snake venom toxin...
The human hepatoblastoma cell line HepG2 produces and secretes hepatitis B virus (HBV) after transfection of cloned HBV DNA. Intact virions do not infect these cells, although they attach to the surface of the HepG2 cell through binding sites in the pre-S1 domain. Entry of enveloped virions into the cell often requires proteolytic cleavage of a viral surface protein that is involved in fusion b...
background: we aimed at evaluating the toxicity effects of low (subtoxic) concentrations of silver nanoparticles (agnp, 5-10 nm) in human hepatoblastoma (hepg2) cell line after and during a period of about one month. methods: xtt and mtt assays were used to draw a dose-response curve ic50 (half maximal inhibitory concentration) value of the agnp on hepg2 cells was calculated to be 2.75-3.0 mg/l...
