introduction: atherosclerosis, hypertension, ischemic diseases, alzheimer’s disease, parkinson disease, cancer and inflammation emerge from imbalance between antioxidant and oxidants. cancer is a most important public health problem in both developed and developing countries. natural antioxidants such as polyphenols are being used for prevention and treatment cancer. polyphenols include phenoli...

Objective(s):Multidrug resistance (MDR) of cancer cells is a major obstacle to successful chemotherapy. Overexpression of breast cancer resistance protein (BCRP) is one of the major causes of MDR. In addition, it has been shown that PI3K/Akt signaling pathway involves in drug resistance. Therefore, we evaluated the effects of novel approaches including siRNA directed against BCRP and targeted t...

Cancer is one of the main causes of mortality. Therapeutic importance in some diseases, especially cancers has led to considering the anti-cancer effects of probiotics more than ever. Probiotics have stimulatory effects on the immunity and suppressor effects on cancer activity. Various studies report that probiotic bacteria have cytotoxicity effects on different types of solid tumors. In this r...

Background:Dysregulation of HOX Transcript Antisense Intergenic RNA (HOTAIR) has been linked to the etiopathogenesis of several human cancers. According to epidemiological evidences, the risk of susceptibility to breast cancer varies among different populations. This study was designed to determine the transcriptional level of HOTAIR in tumor cells of breast cancer pat...

Cancer is a fatal disease and relatively widespread in the world; Breast cancer is the most prevalent cancer among women. Hydroxyurea (HU) is a chemotherapy drug for the cure of cancer different types in patients, for example breast cancer, but has several defects, for to remove these problems in this study a nanoliposome (NL) suspension for Hydroxyurea (HU) delivery in breast cancer cell thera...

a multiple colorimetric assay has been introduced to evaluate the proliferation and determination of survival fraction (sf) of irradiated cells. the estimation of sf based on the cell‑growth curve information is the major advantage of this assay. in this study, the utility of multiple‑mts assay for the sf estimation of irradiated ht‑29 colon cancer cells, which were plated before irradiation, w...

objective(s): development of molecules that specifically recognize cancer cells is one of the major areas in cancer research. human epidermal growth factor receptor 2 (her2) is specifically expressed on the surface of breast cancer cells. her2 is associated with an aggressive phenotype and poor prognosis. in this study we aimed to isolate rna aptamers that specifically bind to her2 overexpressi...

background: regulatory t cells (t-regs) have an important role in cancer by suppression of protective antitumor immune responses. regulatory t cells express the forkhead/winged helix transcription factor (foxp3) and ox40 molecules which have important regulatory roles in the immune system. objective: to evaluate foxp3 and ox40 transcripts in the peripheral blood mononuclear cells of women with ...

Sophora pachycarpa Schrenk ex C.A.Mey. belongs to the family Fabaceae. Some species of the genus Sophora have shown to possess anti-proliferative and apoptosis-inducing activites in cancer cells. However, there is no available information addressing this effect in S. pachycarpa. Here, we investigated the cytotoxic effects of methanol extract and different fractions obtained from S. pachycarpa r...
