Percentage reduction in CYP1A1 and CYP1B1 expression levels and benzo[a]pyrene-diol-epoxide-DNA adduct (BPdG) levels in the presence of chlorophyllin for normal human mammary epithelial cells from 20 individual donors that were exposed to benzo[a]pyrene in vitro. This box and whisker plot indicates the median percentage and 25% and 75% percentage changes, and outliers are indicated by the whiskers. The mean values are indicated by arrows marked M, these values are 41.1 (±6.5 SE) for CYP1A1, 41.0 (±6.7 SE) for CYP1B1, and 53% (±4.2 SE) for BPdG. These changes were statistically significant p < 0.005 for CYP1A1, p < 0.005 for CYP1B1 and p < 0.0005 for BPdG adducts.
