MTOR and breast cancer: The mechanism of action of biochanin-A in breast cancer by dephosphorylation of HER-2 receptor and MAPK or ERK1/2 causing blockade of cancer cell development, growth, metastasis, and mitogenesis, the inhibition of Akt phosphorylation and downregulation of mTOR signals that disrupt the cell cycle, the inhibition of NF-kB and interrupted transcription and blockade of topoisomerase-II and DNA replication is depicted inFigure 2.
