摘要: Osteosarcoma (OS) is the most common primary malignant tumor of bone with a high propensity for lung metastasis. Despite significant advances in surgical techniques and chemotherapeutic regimens over the past few decades, there has been minimal improvement in OS patient survival. There is an urgent need to identify novel antitumor agents to treat human OS. Repurposing the clinically-used drugs represents a rapid and effective approach to the development of new anticancer agents. The anthelmintic drug niclosamide has recently been identified as a potential anticancer agent in human cancers. Here, we investigate if niclosamide can be developed as an anti-OS drug. We find that niclosamide can effectively inhibit OS cell proliferation and survival at low micromolar concentrations. Cell migration and wounding closure are significantly inhibited by niclosamide. Niclosamide induces cell apoptosis and inhibits cell cycle progression in OS cells. Analysis of niclosamide’s effect on 11 cancer-related signal pathway reporters reveals that three of them, the E2F1, AP1, and c-Myc-responsive reporters, are significantly inhibited. To a lesser extent, the HIF1α, TCF/LEF, CREB, NFκB, Smad/TGFβ, and Rbpj/Notch pathway reporters are also inhibited, while the NFAT and Wnt/β-catenin reporters are not significantly affected by niclosamide treatment. We demonstrate that the expression of c-Fos, c-Jun. E2F1, and c-Myc in OS cells is effectively inhibited by niclosamide. Furthermore, niclosamide is shown to effectively inhibit tumor growth in a mouse xenograft tumor model of human osteosarcoma cells. Taken together, these results strongly suggest that niclosamide may exert its anticancer activity in OS cells by targeting multiple signaling pathways. Future investigations should be directed to exploring the antitumor activity in clinically relevant OS models and ultimately in clinical trials.
