the role of antioxidants in prevention and treatment of cancers have been reported by several studies. in our investigation we studied the effects of ascorbic acid, ?-tocopherol, and sodium selenite on proliferation of two breast cancer cell lines: t47d (estrogen-receptor positive) and mda-mb-231 (estrogen-receptor negative). we also used 17-?-estradiol as positive control for proliferation of ...

current therapies for breast cancer are often limited by short-term efficacy due to the emergence of drug resistance. there has been increased interest in the use of naturally occurring compounds with chemopreventive and chemotherapeutic effects in the treatment of cancers. saffron, dry stigmas crocus sativus l., used in iran as a spice, is known for its anticancer properties. in this study, th...

A new series of 1,2-diaryl-4,5,6,7-tetrahydro-1H-benzo[d]imidazoles, possessing trimethoxy phenyl pharmacophore, were synthesized to evaluate their biological activities as tubulin inhibitors. Cytotoxic activity of the synthesized compounds 7a-f was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HEPG2 (liver hepatocellular cells), A549 (adenocarcinomic h...

Objective(s): Breast cancer remains a global challenge, and further chemopreventive therapies are still immediately required. Emerging evidence has revealed the potent anti-cancer effects of biguanides, Metformin (MET) and phenformin (PHE). Thus, to explore an efficient chemopreventive strategy for breast cancer, the antiproliferative effects of the combination of MET and PHE against breast can...

Background: Breast cancer is one of the most common cancers among women worldwide. Tumor protein 53 (TP53) and its regulator the mouse double murine 2 (MDM2) have important roles in tumorigenesis by playing key roles in cell division and response to DNA damage. MDM2 SNP309 T>G (rs2279744) polymorphism in the promoter region of MDM2 gene can cause dysfunction and inactivation of TP53 which promo...

Objective: Inhibition of lipid metabolism in breast cancer has been suggested as an effective approach for cancer therapy. Saffron-derived crocetin (Crt) and crocin (Cro) with the known anticancer activity, have shown hypolipidemic effect in diabetes and atherosclerosis. Here, we investigated the effect of Crt/Cro on lipid content in breast cancer. Materials and M...

background: exposure to endogenous hormones such as estrogen is known as a lifetime breast cancer (bc) risk factor. polymorphisms in genes that are involved in the steroidogenic process, such as cytochrome p450c17alpha ( cyp17) , affect individuals’ susceptibility to bc. in iran, the highest incident of bc is among young women. this study aimed to find prevalence of single nucleotide polymorphi...

Introduction: Breast cancer is the most common malignancy in women worldwide. It also second leading cause of death among after lung cancer. Considering relationship plasma folate levels, level uracil, and DNA damage cell division, methyl tetrahydrofolate reductase (MTHFR) a suitable candidate for studies on susceptibility to cancer, including breast This study aimed investigate between two pol...
