MCF10A cells transfected with 100 nM control RNA (cRNA) or p63-specific siRNA (p63siRNA) 14 or 15 were kept in 3D culture for 3 h and assayed for Irf6 expression by Western blotting. β-actin was used as a loading control in one experiment, and α-tubulin was used as a loading control in another independent experiment. Films were scanned, and densitometric analysis of the resulting digital images was performed. Irf6 protein levels were normalized to those of the loading controls. The data represent the average of two independent experiments plus the SD. * p < 0.05. (PPT 53 kb) 2018-12-13 05:00:00 Anoikis Apoptosis ErbB2 Irf6 Breast cancer
