Figure 4. Venn diagrams depicting the anti-estrogen specific effects on estrogen-dependent and -independent genes.

(A) Venn of genes whose expression levels were significantly altered by 1.5 fold or greater in MCF7 cells treated with 10 nM estrogen plus 100 nM concentrations of indicated anti-estrogens, relative to cells treated with estrogen alone following 24 hours of exposure. (B) Venn diagram of genes whose expression levels were significantly altered by 1.5 fold or greater in MCF7 cells treated with 10 nM estrogen plus 100 nM concentrations of indicated anti-estrogens, but not by estrogen treatment alone, relative to vehicle treated controls following 24 hours of exposure.
