Objective To assess the effects of thalidomide on VEGF mRNA level in human breast cancer cell lines. Methods Breast cancer cells were treated with thalidomide for 24～72h, RT-PCR was uced to detect the level of VEGF mRNA expression. Results When the concentration of drug is 50μg/L,thalidomide strongly inhibited the level of VEGF mRNA expression. Conclusion Within certain concentration range of thalidomide can inhibit the level of VEGF mRNA expression in breast cancer cell.
