(A) Cyclin-dependent kinase inhibitor 3 silencing downregulated PCNA, Bcl-2, vimentin and RhoA expression levels, and upregulated Bax expression levels in (B) MCF-7 and (C) BT474 cells. Data are presented as the mean ± standard deviation. *P<0.05; **P<0.01; ***P<0.001 compared with the control group. PCNA, proliferating cell nuclear antigen; Bcl-2, B-cell lymphoma 2; Bax, Bcl-2-associated X protein; RhoA, Ras homolog gene family, member A; siRNA, small interfering RNA; GAPDH, glyceraldehyde 3-phosphate dehydrogenase.
