Antiproliferation effect of Pinocembrin (PCB) on breast cancer (BC) cells. (A) The chemical structure of PCB. (B) BC cells (MCF-7, MDA-MB-231, and SKBR3) and breast epithelial cells (MCF-10A) were incubated with 0, 20, 40, 80, 120, 160, 200, or 240 μM PCB for 48 or 72 h. The viabilities of cells in the different treatment groups were measured with the CCK-8 assay. (C) PCB treatment inhibited colony formation of MCF-7, MDA-MB-231, and SKBR3 cells. *p < 0.05, **p < 0.01 vs. the control group.
