Purpose: To determine the effect of melatonin in combination with capecitabine on proliferation and induction apoptosis MCF-7 SK-BR-3 breast cancer cell lines.Methods: The MTT assay (3- (4,5-dimethylthiazol-2-yl) -2,5-diphenyltetrazolium bromide) was performed to investigate lines half-maximal concentration (IC50) index. Expression apoptotic markers, Bax, Bcl-2, caspase-3 were measured by polym...

background and aims: epigallocatechin-3-gallate (egcg) is a polyphenolic compound from green tea, which its anticancer effects on many types of cancers have been confirmed, but the molecular mechanism by which egcg induces apoptosis remains unknown. the aim of the present study was to investigate anti-proliferative properties and apoptotic signaling pathway of egcg on pc3 human prostate cancer ...

BACKGROUND Bax and Bcl-2 are the major members of Bcl-2 family whose play a key role in tumor progression or inhibition of intrinsic apoptotic pathway triggered by mitochondrial dysfunction. Therefore, the balance between pro- and anti-apoptotic members of this family can determine the cellular fate. METHODS In this study, the relative level of mRNA expression of Bax and Bcl-2 genes was deter...

Background: BCL-2 is the most important anti-apoptotic regulator and Bax is a pro-apoptotic protein. The status of these parameters or the ration of BCL-2 to BAX is important in malignant cell fate as well as normal cells. Methods: Sixty-two ALL patients and 62 healthy sex-and age-matched controls were studied. After genotyping, the promoter region of the BAX and BCL-2 genes by RFLP-PCR meth...

Background and Aims: Cadmium is an important environmental pollutant and a potent toxicant to organisms. However, the toxicity of Cadmium and its influences on stomach is still unclear. We examined the effects of intraperitoneal injection of Cadmium on mRNA expression of Bcl-2 and Bax genes in rat stomach. Materials and Methods: Twenty eight male Wistar rats weighing 200 to 250 g were randomly...

Background and objectives: Epidemiological studies have shown that high dose of ethanol can lead to apoptosis. On the other hand, the consumption of medicinal plants such as turmeric in the diet and performing physical activities are considered as factors to control apoptosis. Therefore, this article aims to mainly evaluate the anti-apoptotic effects of swimming and curcumin interactively durin...

Objective(s): Radiotherapy is one of the most effective modalities of cancer therapy, but clinical responses of individual patients varies considerably. To enhance treatment efficiency it is essential to implement an individual-based treatment. The aim of present study was to identify the mechanism of intrinsic apoptosis pathway on radiosensitivity and normal tissue complications caused by the ...

The inability to undergo apoptosis is a crucial mechanism of multidrug resistance in acute myeloid leukemia (AML), and the analysis of mitochondrial apoptotic proteins may represent a significant prognostic tool to predict outcome. Bcl-2 and Bax oncoproteins were evaluated in 255 de novo AML patients (pts) by flow cytometry using an anti-bcl-2 monoclonal antibody (MoAb) and an anti-bax MoAb. Th...
