multipotent mesenchymal stem cells (mscs) are recently found to alter the tumor condition. however their exact role in tumor development is not yet fully unraveled. mscs were established to perform many of their actions through paracrine effect. thus investigation of msc secretome interaction with tumor cells may provide important information for scientists who are attempting to apply stem cell...

melanocortin-1 (mc1) receptor is an attractive melanoma-specific target for the development of α-msh peptide based imaging and therapeutic agents. in this work a new lactam bridge α-msh analogue was synthesized and radiolabeled with 99mtc via hynic chelator and tricine as co-ligand. also, stability in human serum, receptor bound internalization and tissue biodistribution in tumor bearing nude m...

the adhesive interaction between tumor cells and the host cells or the extracellular matrix plays a crucial role in tumor metastasis. to evaluate the mediation of cell adhesion by daphne mucronata, an anti-cancer medicinal plant in iranian folk medicine, the adhesion of thrombin activated human platelets to the cultured monocytes or hl-60 cells was investigated under the effect of the plant ext...

The cytotoxic activity of ethanolic extracts of Thymus vulgaris, Thuja orientalis and Achillea millefolium was investigated on various growing tumor cell lines. MTT colorimetric assay was used for measuring the inhibition of cell proliferation. All of the three extracts showed a relatively dose-dependent inhibition of proliferation of human breast cancer (SK-Br-3, MDA-MB-435) and leukemia ...
