Background and objectives: Plants have been used to treat diseases like cancer for many years and today the trend towards their use is increasing. One of the most effective mechanisms of plants against cancer is inducing apoptosis. Apoptosis is a programmed cell death which acts opposite to cell division. It starts in response to some stimuli. Despite the effectiveness of apopt...

Objective(s):Genetic and environmental factors are involved in the pathogenesis of systemic lupus erythematosus (SLE). Autoreactive lymphocytes are cleared through apoptosis and any disturbance in the apoptosis or clearance of apoptotic cells may disturb tolerance and lead to autoimmunity. Vitamin D has anti-proliferative effects and controls cell cycle progression. In this study we investigate...

Objective(s): T-cell acute lymphoblastic leukemia (T-ALL) is an aggressive hematologic malignant tumor. Administration of chemical compounds influencing apoptosis and T cell development has been discussed as promising novel therapeutic strategies. Valproic acid (VPA) as a recently emerged anti-neoplastic histone deacetylase (HDAC) inhibitor and pioglitazone (PGZ) as a high-affinity peroxisome p...

abstractferulago angulata boiss. known in iran as chavir, has some bioactive compounds having antioxidant activity. because of its antioxidant activities, it sounded chavir extract can be a good candidate for finding chemopreventive agents having inductive apoptosis properties on cancer cells. in this study, the cytotoxic effects and proapoptotic activities of chavir’s leaf and flower extracts ...

introduction: it has been reported that platelets can eradicate tumor cells in vitro, although the mechanism of this effect has not been determined. the effect of platelets on the induction of apoptosis in tumor cells is largely unknown. materials and methods: to investigate this effect, two human hematologic cell lines, k562 and daudi, were independently faced with unstimulated and thrombin-ac...

Introduction: Hormesis and adaptive responses are two important biological effects of low-dose ionizing radiation (LDIR) in organism and mammalian cell lines. Notably, LDIR generates distinct biological effects in cancer cells from normal cells, e.g., it may affect the growth of cancer cells via the activation of certain cell signaling pathway, which does not exist in normal ...

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...

Objective(s): The purpose of this study was to investigate cytotoxicity and membrane toxicity effects induced by Mesobuthus eupeus venom (MEV) on the HT-29 cell line. Materials and Methods: To determine the in vitro cytotoxicity via MTT assays, HT-29 (as cancer cell line) and Hek-293T (as normal cell) were treated through different conce...

Objective(s): The purpose of this study was to investigate the role of chloride channel protein 2 (ClC-2) in glutamate-induced apoptosis in the retinal ganglion cell line (RGC-5). Materials and Methods: RGC-5 cells were treated with 1 mM glutamate for 24 hr. The expression of ClC-2, Bax, and Bcl-2 was detected by western blot analysis. Cell survival and apoptosis were measured by 3-(4,5-dimeth...
