Frontiers of Medicine 2009, Volume 3, Issue 3,   Pages 336-340 doi: 10.1007/s11684-009-0053-2

Abstract: Lanthanum salt is a prescription drug, but its underlying functions and mechanisms are not fully understood currently. To explore the potential therapeutic value of , cytotoxicity test was applied to investigate its effects on cell proliferation. Furthermore, we observed its influence on pro-oncogene by reverse transcription polymerase chain reaction (RT-PCR). In MCF-7 cell line, repressed cell proliferation at high concentration but had no significant inhibition effect on cell growth at low concentration. However, we observed that repressed transcription at a low concentration. This may suggest that is a potent drug to inhibit the high expression of in carcinoma cells and play a clue for inhibiting the growth and invasion of tumor.
