Propofol, an intravenous anesthetic agent, has been found to inhibit growth of breast cancer cells. However, the mechanisms underlying the antitumor are not known. A recent report has found that propofol could significantly downregulate miR-24 expression in the human malignant cancers. In breast cancer cells, overexpression of miR-24 promotes cell proliferation and inhibits cell apoptosis by downregulation of p27. The miR-24 has been reported to be overexpressed in breast cancer and breast cancer cell lines. In the present study, we hypothesized that propofol induces apoptosis of breast cancer cells by miR-24/p27 signal pathway.
