This research aimed to assess the impact of static magnetic field (SMF) on apoptosis rate and cell cycle progression in presence Aloe vera Crude Extract (ACE) normal (Huo2) cancer cells (HeLa). The specimens were split into one untreated group (control) two experimental groups, including treatment with ACE (Alo) compound SMF (Alo+SMF). MTT assay determined IC50 value, flow cytometry was employe...

During their passage through the circulatory system, tumor cells undergo extensive interactions with various host cells including endothelial cells and platelets. Mechanisms mediating tumor cell adhesion, migration, and metastasis to vessel wall under flow condition are largely unknown. The aim of this study was to investigate the potential roles of GPIIb/IIIa and alphavbeta3 integrins underlyi...

conclusions these results suggest that toxins induce inflammatory responses, particularly through expression of chemokine. recombinant stx and native toxin induced apoptosis by balancing between different pro- and anti-apoptotic bcl-2 family-factors in epithelial cells. in this study, for the first time, recombinant and native stx induction of apoptotic factors and stimulation of immune respons...

It has been reported that several conifers possess cytotoxic activities on some human tumor cell lines. Taxol as a natural cytotoxic compound has been extracted from this family. In a program to screen the cytotoxic effects of natural resources, male and female branchlets, fruit or bark of two different species of Iranian conifers were collected, identified and the cytotoxic effects of their hy...

Background: Essential oils are found to have multiple active components which can show in vitro cytotoxic action against various cancerous cell lines. This study reports the in vitro cytotoxic effects of the essential oil from Artemisia absinthium L. (Asteraceae) growing wild in Iran. Methods: Water-distilled essential oil of A. absinthium collected from Ardabil, north-western Iran, was examin...

Background: Gemcitabine (2′, 2′-difluoro-2′- deoxycytidine, an analogue of deoxycytidine) is a relatively new drug with wide range of anti-cancer activity. In this study, radiosensitizing effects of gemcitabine was investigated on HeLa and MRC5 human originated cell lines under both chronically hypoxic and normoxic conditions using the micronucleus (MN) assay. Materials and Methods: F...
