Abstract:
Objective To investigate the cytotoxicity on normal cell lines of cerium nitrate, the inhibitory effect on tumor cell lines and the effect on cell cycle in vitro. Methods The cytotoxicity of cerium nitrate on FL, L929 and inhibition rate on Hela, SGC-7901, B16, Lewis, K562, and H_(22) in vitro were detected with the method of MTT. The effect of cerium nitrate on cell cycle of SGC-7901 was studied by one-fluorescence dying method on flow cytometer. Results Cerium nitrate did not show the toxic activities on FL and L929 cell lines when the dose of cerium nitrate was it could noticeably inhibit the growth and proliferation of tumor cells nitrate inhibited the growth and proliferation of tumer cells including HeLa, SGC-7901, B16 and K562; cerium nitrate had a noticeably inhibitory effect on the growth and proliferation of H_(22) cell lines in vitro on Conclusion Cerium nitrate has the property of low toxicity and high selectivity on normal cells, but it can inhibit growth and proliferation of many kinds of tumor cell lines by adjusting cell cycle.
