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...

A series of Adriamycin-resistant human breast MCF-7 and human colon DLD-1 cancer cell lines were established by stepwise selection. The concentration of Adriamycin required to inhibit cell proliferation by 50% (IC50) in the parent breast line (MCF-7), Adriamycin-resistant lines (MCF-Ad5 and MCF-Ad10), and a 5-fluorouracil (5-FU)-revertant line (MCF-R) was 0.005, 3.3, 6, and 4.9 microM, respecti...

Chaharmahal and Bakhtiari province is a most important endemism states of flora of Iran with a considerable plant species diversity in the country. In the present study the cytotoxic activity of 13 plant species grown in Chaharmahal and Bakhtiari have been evaluated on prostate (PC-3), breast (MCF-7), liver (HepG2), ovary (CHO) and melanoma (B16-F10) cancer cell lines. The cytotoxicity and apop...

Luminal A breast cancer usually responds to hormonal therapies but does not benefit from chemotherapies, including microtubule-targeted paclitaxel. MicroRNAs could play a role in mediating this differential response. In this study, we examined the role of micro RNA 100 (miR-100) in the sensitivity of breast cancer to paclitaxel treatment. We found that while miR-100 was downregulated in both hu...

      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...

conclusions these results show that zen and α-zol enhance the rate of cell division in er positive cells and therefore, exposure to this mycotoxin may increase the risk of breast cancer. results the results obtained from the present study demonstrated that both zen and α-zol enhance the cell viability of mcf-7 especially at low doses (1 - 500 ng/ml) and at a high dose of 125µg/ml after 24 and 4...

This study aimed to synthesis of new compounds that containing nitrogen atom and test their anticancer activity. New alkaloids have been synthesized 1H, 13C NMR, IR LC-MS thoroughly characterized. Cytotoxicity was measured against the MCF-7 human breast cell lines. The results showed better significant cytotoxic activity RU8 followed by RU6 finally RU7 cancer lines MCF-7.
