Expression of the estrogen receptor alpha (ERα) and the androgen receptor (AR) in CAMA-1, MCF-7, and MCF7-AR1 breast cancer cell lines at the protein level

Cell extracts were prepared during exponential proliferation in maintenance medium containing 10% fetal bovine serum. Immunoblots were performed as described in Materials and methods. A representative immunoblot. Relative expression of sex steroid receptors quantified to actin content. Each bar represents the mean ± standard error of the mean of four independent experiments. Double asterisk indicates < 0.01 versus wild-type MCF-7 cells as determined by an analysis of variance followed by a Bonferroni test.<p><b>Copyright information:</b></p><p>Taken from "1,1-dichloro-2,2-bis(-chlorophenyl)ethylene (-DDE) disrupts the estrogen-androgen balance regulating the growth of hormone-dependent breast cancer cells"</p><p>http://breast-cancer-research.com/content/10/1/R16</p><p>Breast Cancer Research : BCR 2008;10(1):R16-R16.</p><p>Published online 14 Feb 2008</p><p>PMCID:PMC2374972.</p><p>
