RESUMO
Aim To study the effects of calycosin on proliferation and migration of human triple-negative breast cancer MDA-MB-231 cells and the underlying mechanisms. Methods MDA-MB-231 cells were intervened by calycosin,and the proliferation ability was detected by CCK-8 method. The apoptosis and cycle of MDA-MB-231 cells were detected by flow cytometry. The effect of calycosin on the migration of MDA-MB-231 cells was observed using cell scratch. The mRNA expression of EMT related genes was detected by RT-PCR. The effects of calycosin on the expression of key proteins of Hippo pathway and EMT related proteins were detected by Western blot. Results Calycosin could significantly inhibit the proliferation,migration and apoptosis of MDA-MB-231 cells,and markedly inhibit the expression of Hippo signaling pathway and EMT related protein. Conclusion Calycosin may induce MDA-MB-231 cell apoptosis,block cell cycle and inhibit cell migration by inhibiting Hippo signaling pathway and EMT pathway.
