ABSTRACT
Aim To study the effect of genistein on apoptosis in human breast cancer MDA-MB-231 cells and the underlying mechanisms. Methods MTT as-say was used to observe the inhibitory rate on human breast cancer MDA-MB-231 cells treated with genistein. Colony assay was used to determine the cell colony formation rate on human breast cancer MDA-MB-231 cells treated with genistein. Western blot was used to detect the expression of Bcl-2, Bax, caspase-3,NF-κB, ERK, p-ERK, JNK and p-JNK in human breast cancer MDA-MB-231 cells treated with genistein. Results The results of MTT assay showed that genistein inhibited the viability of breast cancer MDA-MB-231 cells in a time- and concentration-de-pendent manner. Colony assay suggested that genistein had an antiproliferative effect on MDA-MB-231 cells. The expression levels of Bcl-2, NF-κB and p-ERK were significantly down-regulated compared with con-trol(P < 0.01). However, the expression of Bax, caspase-3 and p-JNK was significantly up-regulated(P<0.01). Conclusions Genistein could inhibit the growth of human breast cancer MDA-MB-231 cells and induce apoptosis,and the mechanism may be related to the inhibition of NF-κB, ERK/MAPK signaling path-ways and the activation of JNK/MAPK signaling path-way.
