Introduction: Free radicals are molecules that have unpaired electrons in their last layer. The excessive production of free radicals causes oxidative stress. Oxidative stress thus adversely alters proteins, DNA and oxidation of the membrane phospholipids. Methods: The cytotoxic effects of zinc oxide nanoparticle were evaluated using MTT (3- (4-5-dimethylthiazol-2-yl) -2,5-difenyltetrazolium br...
One new coumarin, dryofracoumarin A (1), and eight known compounds 2-9 were isolated from Dryopteris fragrans (L.) Schott. Their structures were established on the basis of extensive spectroscopic data analyses and comparison with reported spectroscopic data. The new compound 1 was determined to be 8-hydroxyl-4-isopropyl-7-methyl-6-methyl-2H-benzopyran-2-one. Two dimers, trans- and cis-3-(3,4-d...
Among the genes regulated by estrogen receptor (ER) are miRNAs that play a role in breast cancer signaling pathways. To determine whether miRNAs are involved in ER-positive breast cancer progression to hormone independence, we profiled the expression of 800 miRNAs in the estrogen-dependent human breast cancer cell line MCF7 and its estrogen-independent derivative MCF7:2A (MCF7:2A) using NanoStr...
Bee venom (BV) was used from long time ago in the medical field as treatment of chronic joint affections. In the recent decades, the screening process of new sources of antimicrobials discovers its high advantageous characteristics for combating various types of microbes, as well as trials to discover its anti-cancer medicinal fields. Lumpy skin disease virus (LSDV) causes disease in cattle of ...

Mentha pulegium L. is one of the Mentha (Labiatae) species that is grown in many different parts of the earth including northern Iran. The total ethanolic extract of the aerial parts of this plant is used in this work to investigate on the possible cytotoxicity on two different cell lines. Human lung carcinoma cells (A549) and human breast cancer (MCF7), have been used to show the clonogenic co...
abstract background and aims: to identify and isolation of viruses a susceptible cell is need which can be primary or line. the use of primary cells is laborious, time consuming and expensive, while the use of cell lines is much easier and faster. irkhbk cell line was originated from primary cells of bovine kidney by continuous passage. the aim of this study was to introduce the irkhbk cell lin...
objective: the study of physiological changes in recombinant cell lines provides useful information to improve production performance. in this study, we investigate the effects of an anti-cd33 chimeric igg4 expression on sp2.0 cell growth. methods: variable region genes of light and heavy chains of monoclonal antibody produced by m195 were cloned in pfuse-clig-hk and pfuse-chig-hg4 expression ...
The aim of the study was to investigate the effect of selected polyphenols: gallic acid (GA) and epigallocatechin gallate (EGCG) on matrix metalloproteinase (MMP-2 and MMP-9) activity in multidrug resistant (MDR) human breast adenocarcinoma cells: MCF7/DOX cells and obtained recently in our laboratory MCF7/DOX500 cells by the permanent selection of MCF7/DOX cells with 500 nM doxorubicin (DOX). ...
background: both azadirachtin and rotenone, two botanical pesticides have shown inhibit the growth of cultured insect cells. the inhibitory effect of rotenone on cell growth is through disruption of electron transport chain, but exact mechanism of effect of azadirachtin on growth of cell is unknown. this study was carried out to compare the effect of these phytochemical on oxygen consumption by...
