backgrounds: evidence is accumulating to support disruption of tissue architecture as a powerful event in tumor formation. for the past four decades, intensive cancer research with the premise of “cancer as a cell based-disease” focused on finding oncogenes or tumor suppressor genes. however, the role of the tissue architecture was neglected. three dimensional (3d) cell cultures which can recap...

Breast cancer is the second main cause of death among women. The use of medicinal plants has been common in many countries since ancient times. The aim of this study was to evaluate the antioxidant and anti-proliferative potential of Achillea millefolium L. The antioxidant activity of the aqueous and hydroalcoholic extracts of Achillea millefolium L. leaf and flower was measured by DPPH and FRA...

background: the metabolically active tumor cells may be characterized by a pronounced adenosine release that regulates the growth and development of the tumor. consequently, the expression pattern of defined receptor subtypes will be an important determinant for specific effects of adenosine on the control of tumor cell growth. in recent studies, the expression profile, signal transduction, mol...

Background: Nisin, an effective natural food preservative, is an antimicrobial peptide produced by Lactococcus lactis. Although it has been mainly studied and developed as a potential alternative for antibiotics, other pharmacological effects of the nisin including cytotoxic and anti-tumor activity have been attracted many attentions.Objectives: Here, we ...

background: quantification of radiation-induced apoptosis in peripheral blood lymphocytes (pbls) has been proposed as a possible screening test for cancer-prone individuals and also for the prediction of normal tissue responses after radiotherapy. materials and methods: the neutral version of the comet assay (single-cell gel electrophoresis) was used 24, 48, 72 hours after irradiation with 8 gy...

Our previous studies revealed an inhibitory effect of ICD-85 (Venom derived peptides) on breast cancer cell line MDA-MB231. ICD-85 was also confirmed by in-vivo studies to suppress the breast tumor in mice. However, the exact mechanism of ICD-85 was unknown. Hence, the present study was undertaken to assess the mechanism of ICD-85 effect as an anti-proliferative agent of cancer cells. The effec...

Introduction: A main choice for cancer treatment is radiotherapy. But, the radiotherapy disadvantage is damages caused by radiation given to normal tissues/organs surrounding cancer. One way to avoid this is via increasing radiosensitization of cancer cells. Gold nanoparticles (GNPs) have shown sensitizing effect on cancer cells by enhancing their absorbed dose. Unlike earlier ...

Cancer Nanovaccines In article number 2104849, Mi Liu and co-workers demonstrate a simple universal method to prepare therapeutic preventive cancer nanovaccines based on tumor tissues/cells. Such show both potent efficacy in lung cancer, melanoma, breast cancer. This can be applied make tumor-cell-based for immunotherapy prevention.

background: the incidence rate of breast cancer has been dramatically increasing since the last decade in iran, and it is now one of the most common female malignant tumors. b?cell lymphoma 2 (bcl2) family is the most important regulator of apoptosis, and ?938c>a single nucleotide polymorphism (snp) of bcl2 gene promoter has been demonstrated to influence breast cancer susceptibility. in this r...
