Kaempferol induces the cell cycle at the G2/M phase in MDA-MB-453 breast cancer cells and reverses the EMT process in gastric, ovarian, and breast cancer cells by modulating key markers such as E-cadherin, Smad2/4, TGF-β, N-cadherin, vimentin, and Snai1 [46,47]. This evidence concerns the gene SMAD2 and breast cancer.
