Effects of IGFBP3-specific siRNA on Bcl-2, Bax, and active caspase-3 expression levels in A431 cells.
Notes: Representative Western blot images and summary data showing Bcl-2 (A, B), Bax (A, C), and active caspase-3 (A, D) protein expression levels in A431 cells transfected with scrambled or IGFBP3-specific siRNA. The OD of each protein was normalized to β-tubulin. Values shown are the mean ± SEM (n = 3–4). *P < 0.05 for scrambled siRNA vs IGFBP3-specific siRNA.
Abbreviations: Bcl-2, B-cell lymphoma-2; IGFBP3, insulin-like growth factor binding protein-3; SEM, standard error of the mean.
