Knockdown of SIL1 promoted the apoptosis in human breast cancer cells. (a) The apoptosis of MDA-MB-231 and MCF7 cells was determined using flow cytometry analysis. (b) The percentage of apoptosis cell numbers was shown in a column diagram, which showed that it was enhanced by the knockdown of SIL1 both in MDA-MB-231 and MCF7 cells. (c) The expressions of apoptosis-related proteins, Bax, Bcl2, and Actived-Caspase9 were determined by western blot analysis. The expressions of Bax and Actived-Caspase9 were increased, but Bcl2 level was decreased after the transfection of si-SIL1 in MDA-MB- 231 (d) and MCF7 (e) cells.
