tumor growth is characterized by uncontrolled cell division. for centuries, silver kushta powder, composed of nano and submicro silver particles, has been used in traditional iranian and pakistani medicine for the treatment of melanoma and breast cancer. we have found that these nanocomposite particles are similar to silver nanoparticles (agnps) in size and shape and that there are so differenc...

The effects of 1-O-octadecyl-2-O-methyl-sn-glycero-3-phosphocholine (ET-18-OCH3), an alkyl lysophospholipid derivative, on the binding of epidermal growth factor (EGF) to human breast cancer cell lines (MCF-7, ZR-75-1, and BT-20), the human epidermoid cancer cell line (A431), and the rat fibroblast cell line (NIH3T3) were investigated. The addition of 10 micrograms/ml ET-18-OCH3 to the growth m...

two set of 2-aryl-5,6-dihydropyrrolo[2,1-a] isoquinolines were designed and synthesized to evaluate their biological activities as topoisomerase inhibitors. cytotoxic activity of the synthesized compounds 4a-e and 7a-d was assessed against several human cancer cell lines, including mcf-7 (breast cancer cell), hepg2 (liver hepatocellular cells), a549 (adenocarcinomic human alveolar basal epithel...

Background: The objective of this study is to evaluate combined effect of Thymoquinone (The main active component of black seeds) with Tamoxifen drug on apoptosis of human breast cancer MCF-7 cells (Noninvasive human breast cancer cell line, estrogen receptor positive). Materials and Methods: The human breast cancer MCF- 7 cells were treated with Tamoxifen (2 μM) alone or in combination with Th...

We present a novel method for deriving network models from molecular profiles of perturbed cellular systems. The network models aim to predict quantitative outcomes of combinatorial perturbations, such as drug pair treatments or multiple genetic alterations. Mathematically, we represent the system by a set of nodes, representing molecular concentrations or cellular processes, a perturbation vec...

Curcuma longa (tumeric) is listed in several therapeutic regimens used the management of cancer. The present study investigated potential cytotoxic effects ethanol extract (turmeric) leaves on HepG2 (a human hepatocellular carcinoma cell line), and MCF-7 mammary gland adenocarcinoma line) cells. cells were exposed to different concentrations; 2, 0.2, 0.02, 0.002, 0.0002, 0.00002, 0.000002 μg/ml...
