Repressing BIRC5 expression could inhibit the proliferation of MDA-MB-231 cells. (A) Immunoblots of BIRC5 protein in MDA-MB-231 cells treated with control siRNA or BIRC5 siRNA. β-actin was used as a loading control. (B) Colony formation assay was used to measure cell proliferative capacity in MDA-MB-231 cells treated with control siRNA or BIRC5 siRNA. *, P < 0.05.
