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...

One of the emerging therapeutic strategies for targeted therapy of cancer is the use of chimeric proteins. The p28 peptide has the ability of selective entrance and activating apoptosis in breast cancer cells. The NRC antimicrobial peptide showed cytotoxic activity on various breast cancer including drug-resistant variants but also normal cell lines. Here we designed a chimeric protein consiste...

objective: thymoquinone (tq), as the main component of nigella sativa plant, shows anticancer properties. this study was aimed to evaluate the combined effect of tq and tamoxifen (tam) on viability and apoptosis of human breast cancer cell lines. materials and methods: in this experimental study, estrogen positive mcf-7 and estrogen negative mda-mb-231 human breast cancer cell lines were induce...

adipocytokines, hormones secreted from adipose tissue, have been shown to be associated with many cancers such as breast, prostate and colorectal cancer. recent studies have indicated that resistin and visfatin, two of these adipokines have high level plasma concentrations in colorectal cancer patients and may be promising biomarkers for colorectal cancer. the aim of this study was to identify ...

nanotechnology has slowly but steadily revolutionized the diagnosis, imaging and treatment of cancer. detecting cancer at earliest stages, locating the tumor at different areas in the body and specific delivery of the drugs to malignant cells including surgically inaccessible tumors are the core areas of medical and pharmaceutical research across the world. in this endeavour, nanodevices have e...

objective: in an attempt to develop safer and more effective gene therapy approaches as a realistic treatment for various forms of cancer, researchers are increasingly using tumor-specific promoters (tsp) to drive the expression of the gene of interest and eradicate cancer cells. in this study, for the first time we introduce the oct-4 promoter as a cancer-specific promoter with a high efficacy...
