phase was significantly reduced, from 85.48% to 51.35%, and the population of cells in the G₂ phase increased markedly from 9.27% to 37.5%, which indicated that kaempferol contributed to the induction of G₂/M arrest. Kaempferol also induced apoptosis and DNA damage in MDA-MB-231 cells. Kaempferol increased the expression levels of γH2AX, cleaved caspase 9, cleaved caspase 3, and p-ATM compared to those of the control group. Collectively, these results showed that kaempferol may be a potential drug for the effective treatment of TNBC.
