introduction : arsenic trioxide (as2o3) causes antitumor effects by various mechanisms, including degradation of pml-rara in the acute promyelocytic cells, growth inhibition and induction of apoptosis. however, the precise mechanisms of these processes remain incompletely understood. the purpose of this study was to evaluate the effects of arsenic trioxide on cell growth, cell cycle regulation ...
fasting, that is usually described as abstinence from all food and drink for a period of time, has been experienced for ages. health, protest, religious expressions of devotion and purification are the most important reasons for fasting. many changes occur in the body during fasting including metabolic, mineral, hormonal, immunological and psychological. its use as one of the oldest therapies a...
background and aims. there is no report on the apoptotic impact of allium sativum l. (garlic) on the oral squamous cell carcinoma (kb); hence, this study was designed to survey the apoptotic effects of garlic fresh juice (gfj) on the kb cells. materials and methods. mtt assay (microculture tetrazolium assay) was carried out to evaluate the cytotoxicity of gfj on kb cells. furthermore, tunel (te...
background and objective: garlic has been known worldwide as a dietary constituent with many pharmacological effects. the present in vitro study was designed to investigate the putative anticancer effect of garlic extract on cancer cells, and if this effect was through apoptosis induction. material and methods: human colon adenocarcinoma cells ht29 were treated with different doses (1, 5 and 1...
apoptotic and cytotoxicity effects of all trans retinoic acid (atra) in cultured human uterine myoma
background: uterine leiomyoma is the most common tumor among the female in the reproductive period. the first step to control the tumor is employing medical treatment. currently gnrh agonists are the most common drugs for medical therapy of uterine myoma. climacteric-like symptoms and osteoporosis and recurrence of the size of tumor after gnrh agonists consumption are among the most common sid...
background and objective: the management of apoptotic cell death has been considered as a putative therapeutic strategy for cancer treatment. in the present study we investigated the putative pro-apoptotic effect of allicin, the main garlic organosulfur component with repeatedly claimed chemopreventive potency, on the human adenocarcinoma cell line ht29 as an apoptosis resistant cell line, in v...
econazole nitrate (en), a synthetic compound, is now in use as a routine antifungal drug. en was shown to have antitumor effect, the tumor cell killing mechanisms, however, remain unclear. in this research, the apoptosis-inducing effect of en on mcf-7 cells was investigated. the results showed that en inhibited the proliferation of mcf-7 cells in a time- and dose-dependent manner by mtt method ...
background: rna interference (rnai) is the mechanism of gene silencing-mediated messenger rna degradation by small interference rna (sirna), which becomes a powerful tool for in vivo research, especially in the areas of cancer. in this research, the potential use of an expression vector as a specific sirna producing tool for silencing of bcr-abl in k562 cell line has been investigated. methods:...
Apoptosis is a complex network of biochemical and molecular pathway with fine regulatory mechanisms that control the death event during several pathological situations in multi cellular organisms. It is the part of normal development that occurs in a variety of diseases and is known as aberrant apoptosis. Pancreatic β cell apoptosis is also a pathological feature which is common in both type 1 ...
objective: it is a firm belief that blood transfusion is life-saving in many situations, but at the same time transfusion complications could be life-threatening. the possible effects of blood transfusion related immunomodulatory (trim) and its related mechanisms is one of the important debatable subjects in the field of blood transfusion medicine. one of the mechanisms through which transfus...
