In vitro anti-proliferative activity of clove extract on human gastric carcinoma

Background and objectives: Cancer cell resistance to common chemotherapy agents is on rise. Plants are considered valuable sources of herbal drugs for cancer therapy. The present study was conducted to investigate the in vitro antioxidant, anti-proliferative, and apoptosis-inducing properties of clove (Syzygium aromaticum L.) extract in human gastric carcinoma...

Antimitotic and antitubulin activity of the tumor inhibitor steganacin.

Steganacin, a newly isolated tumor inhibitor, completely inhibits cleavage in sea urchin eggs at 3 X 10(-7) M by preventing the formation of the mitotic apparatus. Steganacin inhibits the polymerization of tubulin in vitro and also causes a slow depolymerization of preformed microtubules. Optical ultracentrifuge studies of steganacin-treated tubulin show a small reduction in 20 S and 30 S peaks...

Tumor-Associated Macrophages Suppress the Cytotoxic Activity of Antimitotic Agents

Antimitotic agents, including Taxol, disrupt microtubule dynamics and cause a protracted mitotic arrest and subsequent cell death. Despite the broad utility of these drugs in breast cancer and other tumor types, clinical response remains variable. Tumor-associated macrophages (TAMs) suppress the duration of Taxol-induced mitotic arrest in breast cancer cells and promote earlier mitotic slippage...
