| Notes | Objective To investigate the role of yes-associated protein （YAP） signaling pathway in morphineinduced migration of breast cancer cells.Methods YAP in BT474 cells was down-regulated using siRNA.Migration assays were conducted using in vitro transwell cell migration assays.Western blots were performed to detect changes of YAP and phosphorylated YAP expressions in breast cancer cells after treatment with morphine.The translocation of YAP in cells was analyzed by immunofluorescence staining.Results The expression of YAP in BT474 cells was significantly inhibited by YAP-siRNA.Morphine could significantly increase the migration of breast cancer cells as compared to that of controls （79.4 ± 5.48 vs.32.2-t-6.42,P=0.0005）.Down-regulated YAP led to inhibition of morphine-induced BT474 cell migration （29.2 ± 4.08 vs.21.2 ± 2.58,P =0.135 9）.In addition,morphine-induced YAP dephosphorylation and nuclear translocation in the time-dependent manner.Conclusion Morphine can promote the metastasis of breast cancer by activatin |
