cancer cell-stromal cell interaction plays a crucial role in the growth and invasion of tumor cells of various organs. it has been recently suggested that adipocytes and preadipocytes, two specific types of stromal cells, affect the biological behavior of variety of breast cancer cell lines. in spite of few investigations, there is a controversy in the literatures about the effects of adipocyte...

A new series of 1,2-diaryl-4,5,6,7-tetrahydro-1H-benzo[d]imidazoles, possessing trimethoxy phenyl pharmacophore, were synthesized to evaluate their biological activities as tubulin inhibitors. Cytotoxic activity of the synthesized compounds 7a-f was assessed against several human cancer cell lines, including MCF-7 (breast cancer cell), HEPG2 (liver hepatocellular cells), A549 (adenocarcinomic h...

conclusions considering the strong historical background about the therapeutic potential of the genus hypericum and the considerable cytotoxic and apoptosis induction ability of hypericum scabrum, this species is suggested for future biological studies. results di-chloromethane fraction demonstrated ic50 values of 25.72 μg/ml and 24.73 μg/ml against ht-29 and hepg-2 cell lines, respectively and...

a hydroponic experiment was conducted to investigate the effect of of magnesium (mg) deficiency on plant cell metabolism in pgs durum wheat cultivar. the experiment was conducted in 4 replications as a completely randomized design in 2010. result showed that magnesium deficiency increased reactive oxygen species (ros) production such as hydrogen peroxide (h2o2). furthermore, mg deficiency decli...

background: the exposure of cell lines to low-dose irradiation leads to changes at molecular level, which may induce adaptive response. we examined radio-adaptive doses effect on human colorectal adenocarcinoma cell line (ht29) and human fetal fibroblasts (mrc5) cell line followed by hyper and hypo fractionation regimes, with main purpose to decrease cell viability in ht29, and at the same time...
