Induction of anti-proliferative pathways by food-derived polyphenols. (A) The effect of food polyphenols on protein expression levels was assessed by immunoblotting after 24 h of treatment at the MED and hMED of the polyphenols and sulforaphane. The results for the densitometric analysis of blots are shown in the lower panel. PARP, poly (ADP-ribose) polymerase (PARP); GAPDH, glyceraldehyde-3-phosphate dehydrogenase. Full, non-adjusted blots are available in Supplementary Fig. 2. (B) Transcription levels of the indicated genes were measured by RT-qPCR. Values are the mean ± SE, n = 3. An asterisk (*) represents a significant difference (p < 0.05) compared to the vehicle control.
