The effect of 72 h incubation with cabbage juices (a, b) and indoles (c, d) on the level of the CYP19 transcript (a, c) and protein (b, d) in MDA-MB-231 cells. The values were calculated as a relative change in transcript or protein level in comparison with control cells (expression equals 1). The mean values ± SEM from three independent experiments run in duplicate (protein) or triplicate (mRNA) are presented. The asterisk above the bar denotes significant difference of mean values from the control group (P < 0.05)
