Induction of apoptosis and inhibition of cell proliferation by the cyclooxgenase enzyme blocker nimesulide in the Ishikawa endometrial cancer cell line.


PMID 22656329

Abstract

Endometrial cancer remains a leading cause of death in women and therefore the development of new therapies is essential. The present study evaluated the effects of nimesulide alone, cisplatin alone, and combination of cisplatin and nimesulide on an Ishikawa cell line with respect to cytotoxicity and induction of apoptosis in vitro. Ishikawa cells were treated with increasing doses of nimesulide alone, cisplatin alone, and a combination of cisplatin and nimesulide. Subsequently their effects on cytotoxicity were investigated by MTT assay, while apoptosis was investigated by DAPI and JC-1 staining and caspase-3 colorimetric assays. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay showed that nimesulide alone and combination of cisplatin and nimesulide have growth inhibitory effect on Ishikawa cells. Nimesulide alone and the combination of cisplatin and nimesulide induced apoptosis. Apoptosis induced by nimesulide might be related to caspase-3 activation. These results suggest that nimesulide treatment is as effective as cisplatin treatment in Ishikawa cells. The combination of cisplatin and nimesulide treatment is more effective than cisplatin alone in Ishikawa cells.
