Growth inhibition of ovarian tumor-initiating cells by niclosamide

ABSTRACT: The gene expression profile in treated CP70 side population spheroid cells (CP70sps cells) was analyzed to investigate the effect of niclosamide inhibition on ovarian tumor-initiating cells. CP70sps cells are isolated and characterized as one kind of ovarian tumor-initiating cells, and they show stemness properties and drug resistance capacity. According gene expression profiles and mechanistic analysis, all evidences revealed niclosamide disrupted multiple metabolic pathways affecting biogenetics, biogenesis and redox regulation. These studies support niclosamide as a promising therapeutic agent for ovarian cancer. CP70sps cells were treated with niclosamide for 0, 2, 4 and 6 hours respectively, and then cells were harvested and analyzed their gene expression profiles.

A recent hypothesis for cancer chemoresistance posits that cytotoxic survival of a subpopulation of tumor progenitors drives the propagation of recurrent disease, underscoring the need for new therapeutics that target such primitive cells. To discover such novel compounds active against drug-resistant ovarian cancer, we identified a subset of chemoresistant ovarian tumor cells fulfilling current definitions of cancer-initiating cells from cell lines and patient tumors using multiple stemness phe  ...[more]
