Figure 1. Ropivacaine inhibits proliferation and promotes apoptosis of breast cancer cells. (A–F) The MCF-7 and MDA-MB-231 cells were treated with ropivacaine (1 mmol/L) or equal volume saline. (A and B) The cell viability was analyzed by the MTT assays in the cells. (C and D) The cell proliferation was measured by the colony formation assays in the cells. (E and F) The cell apoptosis was measure by flow cytometry analysis in the cells. N = 3, The independent experiments were repeated for three times. Data are presented as mean ± SD. Statistic significant differences were indicated: ^*P < 0.05, ^**P < 0.01.
