| pubmed-article:3351366 | pubmed:abstractText | The present study was designed to potentiate the antitumor effects of cisplatin by combination with calmodulin antagonists (W-7 and W-5) by using nude mice bearing human ovarian carcinoma. Tumor growth in nude mice treated with W-7 or W-5 combined with cisplatin was significantly inhibited, compared to that in nude mice treated with W-7 alone, W-5 alone or cisplatin alone. Although treatment with cisplatin alone markedly inhibited lytic activity of the spleen cells from tumor bearing nude mice against the tumor cells, the inhibitory effect was eliminated by combination with W-7 or W-5. There was no significant difference in the survival time among untreated, cisplatin-treated, W-7-treated and W-5-treated groups. Only when cisplatin was followed by W-7 or W-5, a significant enhancement by W-7 or W-5 of the antitumor effect of cisplatin was observed with respect to inhibition of the tumor growth as well as prolongation of the survival time. | lld:pubmed |
